Using the CCBB Files to Control a Drive over Modbus

(65 mins)

About This Lab

This lab demonstrates how to connect and control a PowerFlex4M drive using a MicroLogix controller over Modbus RTU.

As Modbus RTU is built into all PowerFlex 4 class drives, controlling a drive on Modbus RTU provides one of the most cost effective methods of control. The MicroLogix 1400 PLC, when used as a Modbus RTU master, communicates with only one drive at a time using explicit messages. This means that the more drives are added to the network, the longer it takes to communicate with all of the drives. Using an explicit message takes around 50ms to communicate with a drive, so a network of up to 16 drives could take 800ms to update all their control commands. Therefore it is important to understand the impact this has on the controlled equipment, by assessing the risks operating the equipment, and whether the response of the drive is dynamic enough for operation. To give some examples:

� Safety related - If an operator presses a stop button, how long will the drive take to respond.

� Operation related – If a drive needs to stop in the same place every time, the variances within explicit messaging will not be repeatable.

As these issues are quite complex, some further discussion on this subject is provided in more detail in Appendix B of this document.

This lab can be executed with control program files included on all revisions of the Connected Components Building Blocks DVD.

What You Will Accomplish In This Lab

� You will use the pre-configured program code from the Connected Components Building Blocks DVD to control the PowerFlex 4M drive using the PanelView Component HMI.

� You will use the pre-configured program code from the Connected Components Building Blocks DVD to backup and restore drive parameters over the network.

� Modify the program to control the drive with the user program.

� Modify the program to count the number of pulses from the proximity sensors, and stop the drive once a set point is reached.

� Change a drive parameter using an explicit message.

7. Click on Read IO Config

8. The following screen should now show your processor type as MicroLogix 1400. Close this I/O configuration screen.

This shows how easy it is to read the I/O configuration of a MicroLogix processor. All connected modules are now uploaded. Normally you need to setup the modules for your process. The MicroLogix 1400 controller can be expanded with 7 I/O modules for a maximum of 256 discrete I/O

14 of 72

9. Now save this file. We will use it later on after having set the drive parameters to allow proper Modbus RTU communications.

10. Although the CCBB program contains the core of our control program, we need to modify the program so that we can use it for our car wash application. We also need to configure the PF4M drive to be able to receive start and stop commands, as well as the speed reference value, from the PLC using Modbus RTU.

Setting up the PowerFlex 4M drive

In this section, you will configure the parameters in the drive necessary for the MicroLogix controller to

communicate with the PowerFlex drive.

As you complete the exercises in this hands-on lab, you will:

� Reset the PowerFlex 4M drive back to the factory default settings.

� Reconfigure the PowerFlex 4M drive to be controlled remotely via its built-in communication port.

� Set the minimum number of parameters that need to be changed from the factory default settings in order to establish communications with the MicroLogix 1400 controller.

Assumptions

� This lab will provide step-by-step instructions for the PowerFlex 4M drive only, however the procedure is very similar for PowerFlex 4, 40 and 400 drives.

� This lab will specify the minimum number of parameters that need to be changed from the factory default settings in order to establish communications with the MicroLogix controller. For an actual machine application, there may be other drive parameters that need to be adjusted as well.

Resetting the PowerFlex 4M drive to factory default settings

It is very easy to visually verify whether the PowerFlex 4M drive is currently configured to be controlled via

the integral keypad (default setting). Just to the left of the green start pushbutton is a green LED. If this

LED is on, then the start and stop pushbuttons are used to start and stop the drive. Just to the left of the

speed potentiometer knob is another green LED. If this LED is on, then the speed potentiometer is used

to adjust the final speed of the drive – clockwise to go faster and counter-clockwise to go slower. Follow

these steps to become familiar with setting the drive back to its factory default settings.

11. If the displays shows anything different than 0.0, press the Esc key (multiple times if necessary) until the display shows “0.0”.

12. Press the Sel key once – the leftmost alphanumeric value displayed should be flashing.

13. Press the Up Arrow or Down Arrow key until the leftmost alphanumeric value displayed is a flashing “P”. Press the Enter key. Now the “P” stops flashing and the rightmost numeric character is flashing.

14. Press the Up Arrow or Down Arrow key until “P112” is displayed.

15. Press the Enter key and a “0” will be displayed as the current value of parameter P112.

16. Press the Enter key again and “0” begins flashing. Press the Up Arrow key to adjust the value to “1” and press the Enter key to enable the default settings. This parameter resets Drive Parameter Set to Default.

17. The display will flash “F048” and the red FAULT LED will flash also. This fault indicates that the drive parameters have been reset to factory default. Press the Red Stop Button to clear the fault. Power cycle the drive by switching the Motor Power switch to 190E until the drive display goes blank, then switching it back to DRIVE.

Make sure that Motor Power Drive switch is in the LEFT position.

18. Since both green LEDs on the front of the drive are on, verify that you can:

� Start the drive by pushing the Green Start Button (if the drive doesn’t start and the display still reads “0.0”, try rotating the speed potentiometer clockwise).

� Then verify that you can stop the drive by pushing the Red Stop Button (note that the drive does not stop immediately, but decelerates at a configured rate to zero).

� Start the drive again and verify that once the drive is done accelerating, the speed potentiometer can be used to speed up or slow down the drive.

� Now stop the drive by pressing the Red Stop Button.

Drive parameter adjustment

Follow these steps to change the default settings so that the drive can be controlled by the MicroLogix

controller via the Modbus network. The first parameter that needs to be adjusted on the drive is the

16 of 72

Modbus network node address. The factory default node address is 100. The Speed Control Building

Block allocates Modbus addresses from 1-16. It is assumed that the drives will be addressed

consecutively starting with address 1. The table below documents the drive Modbus node address

parameter numbers and the Value to which it has to be set for this lab.

Drive Type Modbus Node Address

Parameter Number

Parameter value to be set

PowerFlex 4M C303 001

PowerFlex 4 A104 001

PowerFlex 40 A104 001

PowerFlex 40P A104 001

PowerFlex 400 C104 001

To change the Modbus node address for the PowerFlex 4M drive, perform the following steps.

19. Press the Esc key (multiple times if necessary) until the display shows “0.0”.


21. Press the Up Arrow or Down Arrow key until the leftmost alphanumeric value displayed is a flashing “C”. Press the Enter key. Now the “C” stops flashing and the rightmost numeric character is flashing.

22. Press the Up Arrow or Down Arrow key until “C303” is displayed.

23. Press the Enter key and the current value of parameter C303 will be displayed, which by default is “100”.

24. Press the Enter key again and “100” begins flashing. Press the Down Arrow key to adjust the value to Modbus node address “001” and then press the Enter key to accept this value.

The other drive parameters that need to be changed from factory default, to allow the MicroLogix

controller to control the drive are the Start Source and Speed Reference parameters. By default, this

pair of parameters is set to “0” meaning “Keypad” control.

Testing the Speed Control Functionality with the User Program

This section will show you how easy it is to do start/stop control over Modbus using the code provided in CCBB. The building block also provides a PanelView Component application for this purpose which will not be used in this lab.

However, we are going to use the PLC code which is placed in the USER_PRGRM routine. It can be modified accordingly to user’s needs so let’s do it.

36. Return to your RSLogix 500/Micro programming software, and double click on the USER_PRGRM routine in the Program Files tree.

37. The original program from the CCBB DVD uses digital inputs that are not wired as per your Demobox, so we need to modify the program to use our Demobox inputs. Double-click on the XIC instruction on rung 0000 (Reset Machine) and instead of the current bit use I:0/17 and then adjust the current description name to Reset Machine.

38. Now, go to the Start Machine XIC instruction on rung 0001, change the currently used bit to I:0/12, and re-assign the description My Start to this bit.

19 of 72

39. Now do the same for Stop Machine input on Rung 0002. Change it to I:0/14 and use My Stop as the description.

40. Right click on the left side of rung 0002, and select Append Rung, then from the Instruction Menu, drag and drop a MOV instruction onto our new rung 0003.

41. Type in the data for the Source as N7:0, and the Dest. as B246:53, so the instruction looks as below. This instruction will allow us to set the required speed in N7:0.

42. Now double-click on the LAD 2 – MAIN routine in the Program Files tree. Select Rung 0000 XIC instruction and delete it. We do not need to condition this program execution during this lab.

43. Click the Verify Project icon at the top of the screen to accept all the changes.

44. Let’s download the program to the PLC. From Comms menu select the System Comms, then select the MicroLogix 1400 at address 192.168.1.2. Now click the Download button

20 of 72

45. The download procedure will then ask if you want to add any revision notes. In this case we don’t need any notes so click the OK button

46. Click Yes to each of the following screens.

47. Observe the program being transferred to the PLC,

21 of 72

48. IMPORTANT: Click to apply communication configurations.

49. Select Yes to go to Run mode and go Online.

50. Your screen should now look like this, with the PLC status shown in green in Remote_Run.

22 of 72

System Validation and Application Tips

Before proceeding, let’s check that communications are working as intended between the MicroLogix

controller and the PowerFlex drive, then between the MicroLogix controller and the PanelView

Component terminal. The operation of the sample Speed Control screens will be described.

The MicroLogix Speed Control routine supports communications with 1-16 PowerFlex 4-Class drives. By

default the routine is configured for communicating with one drive, addressed to node address 1.

51. Check to see if the MicroLogix controller is in RUN mode by inspecting the RUN LED next to the LCD screen to see if it is on. If not, you can change the controller to RUN mode using either the programming software or through the Mode Switch function of the MicroLogix LCD display.

52. The mode can be changed on the controller by pressing ESC (multiple times if necessary) to get to the menu selections of:

� I/O Status

� Monitoring

� Mode Switch

53. Scroll down to Mode Switch and press OK. Scroll down to Run and press OK. The RUN green LED next to the display screen should now be lit. Scroll up to Remote and press OK.

54. The Speed Control routine should now be constantly communicating with the drive via communication Channel 0. Inspect the “COMM0” LCD indicator in the top left corner of the LCD display and verify that it is flashing rapidly.

55. If the “COMM0” LCD indicator is only flashing once every couple of seconds, then the drive is not responding to the MicroLogix communication attempts. Go back and verify the wiring connections and the drive communication parameters settings.

56. If the “COMM0” LCD indicator is always off, then either the MicroLogix controller is not in RUN mode or the Speed Control routine was not properly downloaded to the controller.

57. Clear any faults on the drive by pressing the red stop button on the drive or by switching ON and OFF the switch DI17 on your Demobox.

58. Double click on the Data File N7 – INTEGER and change the value of N7:0 (in range 0-600). Use Base DI12 button to start the drive, and Base DI14 button to stop the drive. Observe the speed of the drive on its display.

59. Now save this file.

Modbus Control of Drives

Although Modbus control of PowerFlex 4 class drives is cost effective, tests have shown that with the default communications, it takes approximately 50ms to get a status update from a PowerFlex4M enabled drive. This means that the time to communicate with further drives is cumulative, with 16 PowerFlex4M drives taking 800ms. Therefore it is important to review any installation with regard to response time and Health & Safety implications.

For More Dynamic Response

Controlling drives on Modbus is better suited to installations that do not need dynamic control of equipment. However starting and stopping a drive is usually more important than controlling the speed reference, which may not change for hours at a time. Therefore for some critical installations, PowerFlex drives could be started / stopped via their digital inputs, with the reference still coming via a message over Modbus. Alternatively PowerFlex 4 class drives have the facility for a broadcast Message over Modbus RTU, which could be setup for all the drives to be started / stopped together, or could be setup for all the drives to be sent a common speed reference. This cuts down on the number of Messages and the response time. Further information is detailed in Appendix B.

Importing the Control Program from a Library File

60. Go offline with your RSLogix500 software, and select Program Files on your project configuration tree, and now right click to select New.

61. Create Program File Number 4 called CARWASH below, and click OK.

62. Double click on LAD 4 - CARWASH and click on rung

0000.

24 of 72

63. Right click and select Paste from SLC Library.

64. Select the file CARWASH.SLC from the Connected Components folder. You will need to browse to the My Documents\Connected Components folder and click Open.

Configuring & Validating PanelView to MicroLogix Communications

The 6” color touch-screen PanelView Component (PVc) terminal communicates with the MicroLogix

controller over Ethernet. The PVc application reads from and writes to the data table of the MicroLogix.

Since the MicroLogix program is continually updating status data from all of the enabled drives into its

data table via Modbus reads, the PVc application is monitoring the latest drive status data.

Follow these steps to verify the IP address of the Ml1400 to which your PVc is reading/writing values

83. Select the CarWash application name in the PVc Dashboard screen and then click Edit. (It takes some time to load this quite complex application.)

84. If you get the following error message,

85. then click OK, click the Firefox Options button and click “Allow popups for 192.168.1.4”.

86. You will need to click Edit again from the Dashboard screen.

As you can see, you don’t need to install any extra software to create or edit a PanelView Component application. It’s built-in to the operator panel.

Ideal for field modifications by service reps or engineers

- View on terminal as you build

- Design time automatically matches the PanelView firmware

- Showing up with the wrong software is no longer a problem

- Updating software for multiple people who only need occasional use is eliminated

34 of 72

87. Click on the Communication tab once the Edit window opens.

88. Verify that the controller type says “MicroLogix 1400” and modify the IP Address to 192.168.1.2 if necessary.

Firmware revs for PVc can be downloaded from

http://www.ab.com/eoi/graphicterminals/panelviewcomponent.html .

Here you can also download, help files, fonts, emulator, objects, graphics, …. .

Note also that PVc provides a lot of multivendor drivers Including GE, Mitsubishi, Omron, Siemens,

Modbus, …

Adding Security to your PVc application.

The PVc panel has 3 levels of security.

1. You can limit the access to the Dashboard page, so that people cannot change IP address, edit, delete, transfer applications, …

2. The second level is to limit the access to the design area of the application so that un-authorized people cannot access or modify the application

3. The third level allows security within your application to grant or deny access to certain displays.

In this section we are going to talk about the third level of security.

* The security screen contains a button ($SysSecurityDisable) to enable or disable security. If you put this button on an unsecured screen you will get a warning from the application validator.

You can secure any screen in an application but the startup screen.

If you do this you will get an error message which means that you cannot complete the validation of the

application. You must remove the security and re-validate.

106. Click the Application Validator : . This will validate the application

The validation process checks for errors and warnings. The application communicates with the connected terminal to perform the validation.

If the validation passes, the Validation Results dialog displays:

No errors or warnings to report

If the validation does not pass, the Validation Results dialog opens. Each result has an ID, Type, and Message.

ID - A unique number the application assigns to the object. You can sort this field in ascending or descending order by clicking the up or down arrow in the header.

Type - The type of message is an Error or Warning. You can sort this field in ascending or descending order by clicking the up or down arrow in the header.

Message - Text describing the cause of the message.

For a screen validation, the message shows the name of the object in error, the problem, and the screen location.

Testing the Speed Control Functionality with PVc

109. Before we start the drive, please check that the demonstration box is selected for drive control. Turn the switch underneath the rotating wheel to the left for Drive Control. On the main screen click on the Yellow configuration button.

110. Once you clicked on the screen the security login is shown. For the configuration screens we need at least Operator rights. So login as ‘David’ with password david.

111. The HMI application loads the Network Overview screen. If the PowerFlex4M drive is showing disabled for Drive#1, press the #1 Disabled button to enable it

Once the PVc terminal is successfully communicating with the MicroLogix, you may observe a drive

status other than “Disabled” or “Ready”. The other possibilities are “Running”, “No Comms” and “Faulted”.

� Running: Indicates that the drive has been started

41 of 72

� No Comms: Indicates that the drive is not responding to communication attempts from the MicroLogix

� Faulted: Indicates that the drive is currently faulted

The original speed HMI application has been translated into English, Portuguese, French, Italian, German, Spanish, Czech and Polish. For this lab only English, Danish and Czech are selected.

112. As we only have one drive at Modbus address 1, we only show Drive#1. The rest of the drives have been removed but are available in the original application. Press the Drive #1 button.

42 of 72

The indicators on the left-hand side show whether the drive is Ready to run (not faulted), Active (running) or not, whether the direction is Forward or Reverse and whether it is running at the reference frequency (At Ref).

The numeric displays in the middle show the Output Current in amps, the Output Voltage in volts, the PLC reference frequency in hertz and the actual frequency in hertz.

113. The Drive #1 screen shown below details the control in Program mode. i.e. the drive would be controlled via start and stop commands from the user program in the PLC. Press the Program button so that commands can be given from the HMI.

114. Press the HMI Ref button, and input a value of 25.00.

Notice that the hertz value entered and hertz value displayed shows two digits to the right of the decimal

point. Although the PowerFlex 4M (along with the 4 and 40) drive only supports one digit to the right of

the decimal point for hertz, the PowerFlex 40P and 400 drives both support two digits to the right of the

decimal point. You must always enter in two digits to the right of the decimal point because this Speed

Control screen is designed to support any of the PowerFlex 4-class drives.

43 of 72

115. Now press the Start button and observe the HMI and drive at 25Hz. Play around with the controls to understand how they work. Note that the Jog button will only function with the drive stopped.

116. Next, verify that when the RJ45 network cable is unplugged from the drive that the “Lost Communication to Device” message flashes at the top of the screen.

117. Plug the RJ45 connector back in and the “Lost Communication to Device” message will automatically go away.

118. Verify that “F081” fault code flashes on the drive display.

119. The PVc screen will have the fault code flashing in a banner near the top of the screen that says “F81 Comm Loss”.

44 of 72

120. Press the F81 Comm Loss banner and a new screen will appear that gives the Fault Type, Description & recommended Action. This screen provides the same information and troubleshooting tips for that particular fault as found in the drive user manual!

121. As with the other screens, press the X button in the upper right-hand corner to go back to the last screen.

122. In order to clear the fault, press the Clear Fault button. After doing so the fault should clear as indicated by the fault display button disappearing, along with the Clear Fault button.

123. Notice that while in “Operator” mode, there is no X button in the upper right-hand corner of the screen. In order to navigate back to the Network Overview, you must first switch the screen mode to “Program”.

124. If you haven’t done so already, switch the screen back to “Program” mode by pressing the Operator button. The button label should now be Program. Press the X button in the upper right-hand corner of the screen to return back to the Network Overview screen.

You now have been testing the PF4M screens that come with the Connected Components Building Block

for Speed control.

What if you don’t have a PanelView Component or you want to do some modifications offline?

45 of 72

For Offline modifications, we offer two options:

1) Emulator: Virtual PanelView Component on PC (development environment exactly like a real terminal)

2) PVc DesignStation (offers the best development performance)

Both are available for free download from:

Using the High Speed Counter for motor feedback

Certain models of the MicroLogix 1400 have 12 high speed inputs which can be configured for high speed counting. In this part of the hands-on, we will configure the proximity sensor on the motor flywheel, as a high speed input to count the number of motor turns. After the specified number of turns the program will stop rotation.

The CCBB program we have modified so far will be further modified.

125. Now we need to go offline, so select the down arrow next to the green REMOTE RUN and select Go Offline

126. Double click the I/O Configuration on the project tree, and select the MicroLogix 1400 Series A in slot 0. Now click on the Adv. Config button

47 of 72

127. Once the I/O Configuration screen pops up, select the Embedded I/O Configuration tab, and change the Input Filter for Inputs 0+1 to a value of 2 mS. Click Apply and OK, and close the I/O Configuration screen.

48 of 72

128. Double click on the Function Files from the project tree, and select the HSC tab and expand the HSC:0 by clicking on the +. You will need to resize the window to see all the tags. Modify the tag values as shown.

The High Speed Counter needs a Program File routine allocated, and in this hands-on lab we have specified HSC:0.PFN = 3. Therefore we need to create the Program File routine 3.

49 of 72

129. Go to the Project tree and right click the Program Files and select New.

130. Enter 3 into the program file Number, and HSC into the Name, and click OK

The Program File routine 3 doesn’t require any code / ladder logic to enable the HSC to work but we will use it to interact with the Car Wash program.

131. Double-click on the LAD 3 – HSC program. Enter the following rung of code:

This program file will be executed once the High Preset of HSC:0 will be reached.

132. Click the Verify Project icon as before. Download to the PLC as before, and go online.

Operating the Car Wash

This section will guide you through the Car Wash application. You will be able to see how all the pieces

created and configured throughout this lab work as a whole. For any reference regarding the PanelView

Component application go to Appendix D of this lab book.

50 of 72

133. You should now be online with your MicroLogix 1400 controller. If not, download the program created in the previous section and go online.

134. The PanelView Component application should be loaded in the terminal and running. If this is not the case, connect to the terminal using your web browser, select the CarWash application and click on the RUN button.

135. From the main screen of the PVC application select the Start Car Wash screen.

136. On the Program Selection screen highlight the Normal_Clean program using the scrolling buttons and select it with the Enter button.

137. Next press the Download button. Once the indicator below changes from IDLE to Download Completed and turns green you know that the recipe was successfully loaded into the controller memory.

138. Having the recipe downloaded we can proceed to the Status screen and operate the Car Wash. Press the Car Wash button in the bottom right corner.

139. Now you can operate your Car Wash. Press the Start button to start a new cycle and observe consecutive steps. You can Stop the cycle at any time and resume by pressing the Start button again. It’s also possible to restart a cycle at any time. Notice that the brushes are simulated by an AC motor while the dryer is simulated by the fan, both located in your demobox.

Appendix B : Controlling PowerFlex Drives on

Modbus RTU with Explicit Messages

Overall Description

This application note provides some guidelines for controlling PowerFlex drives on Modbus RTU using explicit messages. This application note details a MicroLogix 1100 PLC being used as the controller, but the guidelines can also be used with other controllers capable of Modbus RTU. This lab takes approximately 15 minutes.

Background

52 of 72

As Modbus RTU is built into all PowerFlex 4 class drives, controlling a drive on Modbus RTU provides one of the most cost effective methods of control. The MicroLogix 1100 PLC when used as a Modbus RTU master, communicates with only one drive at a time, using explicit messages. This means that with more drives on the network, the longer it takes to communicate with all the drives. When explicit messages are used for control, it is important to understand how a message instruction works, and the risks and associated limitations when used.

A message instruction is configured as part of the ladder logic in the user program. When the ladder logic is processed and the message instruction is enabled, the contents of the message instruction are passed to one of the free communication buffers (ML1100 has 4 buffers), or the message queue if the buffers are all used. The message instruction will then be executed when the ladder completes, within the service communication interval. If the destination drive receives the data correctly, then it issues an ACK, and the message instruction completes and releases the buffer for further use.

To control a PowerFlex 4 class drive, the PLC needs to send a Message write instruction, for the Logic control and the Speed Reference. To get the status of a PowerFlex 4 class drive, the PLC needs to send a further Message read instruction, for the Logic Status and the Speed Feedback.

Although the specification of Modbus RTU allows for a maximum of 247 nodes, divided into a maximum segment size of 32 nodes, in practice the number of drives that can be controlled is significantly less than 31, as co-ordinating the number of messages becomes difficult. So as further drives are added, each message needs to be sequential to the last, and so the time response to the control word is cumulative. Therefore it is important to review any installation with regard to response time and Health & Safety implications. The limitations are detailed below:

Limitations

Most PLCs have a real time scheduler to control the program and normal I/O, with messages being unscheduled at the end of the ladder logic (service interval). This means that real time scheduler often interupts the message handler, and so messages have no priority. Therefore a message may be be updated within 1 to many program scans, which means that it is difficult to determine how long the drive will take to start / stop when the command is given. Therefore all equipment used in this manner, should be subject to a risk assessment, taking into account the mechanical and electrical implementation.

PLCs typically have a limited number of communication buffers / queue size (refer to PLC user manuals for max buffers – ML1100 has 4). If the message buffers and the queue are both full, messages will be executed at random or even lost. In addition, the Message instruction requires an ACKnowledgement response from the drive, before the Message instruction is complete. As further drives are added, they will need additional explicit messages for control. Therefore it is important these messages have their ACK, before moving to the next message. So the messages need to be carefully sequenced / managed within the program, if messages are not to be lost. This will limit the number of drives that can be connected on Modbus.

Modbus RTU uses the serial physical layer RS485 which is capable of in excess of 1000 m. However tests have shown that small drives using fast IGBTs produce significant electrical noise and interference. This noise / interference is picked up in the RS485 cabling, and may result in the drive dropping off the network, or indeterminate behavior. Therefore any installation should follow the good practice guidelines outlined in GMC-RM001A-EN-P, routing the Modbus cable well away from the drive and other cabling. Experience has shown that Modbus cabling should be kept to a minimum. i.e. within a cabinet.

53 of 72

To check for loss of communications, a time-out value (parameter in seconds) can be setup in the drive to issue a drive fault. This needs to be set to a value, in excess of that taken to message the maximum number of drives, and so needs to be in the order of seconds.

Controlling drives on Modbus is better suited to installations that do not need dynamic control of equipment. Usually starting and stopping a drive is more important than controlling the speed reference, which may not change for hours at a time. Therefore for some critical installations, PowerFlex drives could be started / stopped via their digital inputs, with the reference still coming via a message over Modbus. Alternatively PowerFlex 4 class drives have the facility for a broadcast Message over Modbus RTU, which could be setup for all the drives to be started /stopped together, or could be setup for all the drives to be sent a common speed reference. This cuts down on the number of Messages and the response time of each drive.

Although Modbus control of PowerFlex 4 class drives is cost effective, the items above effectively limit the number of drives that can be controlled. Tests have shown that with the default communications, it takes approximately 50ms to get a status update from each enabled drive. The PowerFlex40P requires 100ms as 2 read requests are made. This means that the time to communicate with further drives is cumulative, with 16 PowerFlex4M drives taking 800ms. Therefore it is important to review any installation with regard to response time and Health & Safety implications.

For an alternative / more dynamic method of control, or for a larger number of drives, PowerFlex drives can use implicit I/O control. This method of control creates a connection to the drive as part of the real time I/O control of the PLC. This method of control is used with the ControlLogix / CompactLogix PLC’s, with EtherNet/IP providing the easiest and most integrated form of implicit I/O control for a PowerFlex drives. Typically this could be around 30 drives in CompactLogix and 60 – 120 in ControlLogix..

The programming software RSLogix5000 v16.x and above for ControlLogix / CompactLogix, contains integrated profiles for PowerFlex drives that with a few clicks of the mouse create all control tags automatically and an implicit I/O connection at the specified Requested Packet Interval to control the drive. This connection is monitored at both ends to ensure that the PLC and drive are communicating. A watchdog will generate a drive fault if the drive doesn’t respond in the order of 100ms. As the drives are connected on EtherNet/IP, all their parameters are visible across web / internet, making remote diagnostics feasible. Therefore using fieldbus in conjunction with ControlLogix / CompactLogix, provides an easier, much more dynamic, deterministic and secure method of controlling drives.

Changing a drive parameter with an explicit message

1. Go offline with your processor, and in the Data Files area of the Project tree, select MG243 – DC MSGS file and right click to select Properties

54 of 72

2. Change the number of Elements to 9 and click OK. This provides an additional MSG instruction MG243:8 for use in our program.

3. Add a line of program in the USER_PRGPR program as shown below, specifying the MSG instruction being MG243:8.

4. Double click on the Setup Screen text of the MSG instruction, and enter the information in the MSG setup below:

The MSG instruction is configured to send Multiple Registers starting from N7:3, and the size is 2 elements of 16 bit. The register will be sent to the Target Device Slave Node address 1, to parameters

55 of 72

starting at 110. Modbus RTU uses the Direct Access method to communicate with the drive whereby 41000 is the base address of the parameters. i.e.

Modbus Address = 41000 + (Drive Parameter # - 1)

Therefore the above is accessing Parameter 109 and 110, so from the PowerFlex4M user manual 22F-UM001x-EN_E

� P109 [Accel Time 1] = values in 0.1 secs

� P110 [Decel Time 1] = values in 0.1 secs

5. Click the Verify Project icon as before. Download to the PLC as before, and go online. Double click of the N7 - INTEGER file, and double click N7:3 and N7:4 to change the values. i.e. 5 = 0.5 sec. Put the value of 400 to N7:0 as drive speed reference.

6. Start the drive using pushbutton DI12 ( notice that it’s just a temporary start command, as soon as you will release the pushbutton the drive will stop. Notice the acceleration and deceleration rate. Now operate the digital input on the demo box DI15 to send the MSG to the drive. The MSG output DN should turn green indicating that the MSG instruction was successful. Now start the drive again to observe the influence of the changed parameters.

7. Now save this file to your Desktop.

Appendix C : Parameter Backup and Restore for

PowerFlex 4-class Drives

Drive Parameter Backup and Restore (PB&R) Capability

PowerFlex 4-Class Drive Parameter Backup & Restore (PB&R) provides the capability of backing up all of

the configured drive parameters for up to 16 PowerFlex 4-class (PF4-class) drives connected on a

Modbus serial RS-485 network. The parameter sets are stored as recipes within a MicroLogix controller,

which is the Modbus master on the network. As recipes, are used to store the Drive parameters, those

are saved as part of the MicroLogix RSLogix program, as well as part of the optional memory module

backup image.

Once a PF4-class drive’s parameters have been backed up to the MicroLogix, if that drive fails and is

replaced with a new drive, the parameters can be quickly restored to the new drive with a few pushes of

the buttons on the front of the MicroLogix, without requiring any programming device and/or software.

This PB&R functionality can be initiated through the MicroLogix keypad and LCD user display.

Alternatively, PB&R can be initiated via the MicroLogix web server using Internet Explorer or directly from

56 of 72

the RSLogix 500 programming software while online with the MicroLogix.

This lab takes approximately 15 minutes.

Assumptions

Before importing the PB&R routine, be sure to confirm all of the following:

� All drives are PowerFlex 4-class drives (PowerFlex 4M, 4, 40, 40P and/or 400).

� All drives are networked together with the MicroLogix using RS-485 serial Modbus RTU.

� The MicroLogix must be the Modbus master on the network.

� The Modbus communication parameters for all devices are set to 9600 baud, 8 data bits, no parity bit and 1 stop bit, which is the factory default settings for PF4-class drives.

� All drive node addresses fall within the range of 1-16.

� No node address 100 exists on network-this is reserved for the device restore functionality, since this is the factory default node address for PF4-class drives.

� Recipe files 0-6 and recipe number 0-16 are available to be used.

� Program files #242-255 and data table files #248-255 are available to be used.

� Enough unused data table and program memory is available.

Merging the PB&R routine into a new or existing program

Follow these steps to merge the PB&R routine into the current Speed Control file.

1. Maximize (or restart) RSLogix 500 software. You should be viewing the offline Speed Control program file.

2. From within RSLogix 500, click File > Open and browse to the *.SLC PB&R file on the CCBB CD: D:\Files\Building Blocks Folder\Simple Speed Folder\PB&R Folder\PB&R_ML1100_PF4M-EN-PBR_PF4M-C0_0x.SLC

57 of 72

3. Click Open.

4. Verify that the following screen appears and after selecting the options as shown, click OK.

5. If either/both of the following warning messages appear, click OK.

58 of 72

6. The operation will automatically start to progress through windows. Once the progress stops you will get a series of warning screens that are similar to what is shown below; click Yes to all.

7. Click on Verify Project in the toolbar.

If you get the following errors after attempting to verify the file:

it is due to the fact that there was a processor mismatch between the Drive Control program file and the PB&R program file (MicroLogix 1100 vs. MicroLogix 1400).

8. To correct this, double click on Controller Properties, change the Processor Type to MicroLogix 1100 Series A, click Apply and then OK to confirm the processor type change.

9. Next, change it back to the MicroLogix 1400 Series A, click Apply and then OK.

10. Click on I/O Configuration,

59 of 72

11. Click on the Read I/O Config button, the configuration will be read, and the project should have verified with no errors.

12. Download the merged file to the MicroLogix.

13. Once the download has completed, a dialog box will appear to ask what mode the MicroLogix 1400 should be placed in. Click Yes to place the MicroLogix 1400 in Run mode.

14. A dialog box will appear asking if you want to go Online, click No.

60 of 72

15. Now save this file to your Desktop. As the drive has probably faulted with a display of F071, you will need to reset the fault. Press the Red Stop button on the drive.

Using the PB&R functionality

Every drive on the Modbus network has a node address between 1 and 16. The Parameter backup

function is initiated by writing in the node number to be backed up into data table word N255:0. Therefore,

the backup can be initiated from any device that can write to N255:0, including the MicroLogix LCD User

Display, the MicroLogix Web Server and RSLogix 500. Similarly the Parameter Restore function is

initiated by writing in the node number of the drive that was replaced into data table word N255:255. The

drive to be restored must be using its factory default communication settings.

From the MicroLogix LCD User Display

Follow these steps to utilize the LCD User Display on the front of the MicroLogix to use the PB&R

function to backup parameters.

16. Make sure that the MicroLogix is in Run or Remote Run mode.

17. Click ESC on the front panel of the ML1400 in order to go to top menu.

18. Move the cursor to User Displ by pressing the Down Arrow to the second screen of categories:

22. The LCD display will give a message “Good Backup for Node #1 ESC to Retrn”. If you do not see this message, notify your instructor.

23. Press ESC once to return to the main PB&R screen.

Before restoring the drive parameters, the drive must be returned back to factory defaults. Go back to Lab 2 and repeat steps 14 - 21. Then power cycle the drive completely off and then back on.

24. Check that the drive is back at factory defaults settings by verifying that the green LED’s close to the start button and the one close to the speed potentiometer are both on.

Follow these steps to utilize the LCD User Display on the front of the MicroLogix to restore parameters to

a drive after previously using the PB&R function to backup that drive’s parameters.

25. On the MicroLogix LCD display, use the Up Arrow pad to increase the displayed value from +00000 to +00002 for “Restore” and press OK.

26. On the following screen use the Up Arrow pad to increase the displayed value up to the node number of the drive to be backed up. For this lab the node address will be 1, then press the Ok button to launch the Drive Parameters Restore

27. You have the option of selecting nodes 1-16 if additional drives were connected.

28. The LCD display will give a message “Good Restore Pwr Cycl #1 ESC to Retrn”. If you do not see this message, notify your instructor.

29. Check that the drive parameters were restored by verifying that the green drive LED’s by the start button and speed potentiometer are now both off.

30. Power cycle the drive for the restored node address to take effect.

31. Press ESC once to return to the main PB&R screen on the MicroLogix.

32. To exit out of the PB&R main screen, press and hold ESC for several seconds.
