I/O ADDRESSING ADDRESSING DETAILS

Since a PLC will be controlling real devices down on a plant floor, it has to have some way of communicating to the correct device. All PLCs use some sort of method of I/O Addressing to perform this function. Although addressing methods may vary, they all perform the same function. They all tie some symbolic representation, that you can use in a program, to a specific device.

8


AB MLX 1400 PLC

EXAMPLE FOR ADDRESSING THE I/0 PORTS.

I:0/1 O:0/1

• I/O addresses are a means to tie a physical I/O point to a location in PLC memory

• An input address will represent the state of an input device, i.e. the switch is on or off.

• An output address will represent the commanded state for a device. i.e., turn the motor on or off.

PROGRAMMING

Software for programming: Rslogix 1400Software for communication: RslinxSoftware for IP address: Bootp.Software for HMI: panel view.Software for servo drive: Motion veiw

Every PLC has associated Programming software, or a dedicated terminal, that allows the user to enter a program into the PLC.

• Most of the software used today is Windows based, and can be run on any PC.

• Software designed to program one controller may not be able to program other PLCs.

11


AB MLX 1400 PLC

Before a PLC can perform any control task, it must be programmed to do so. The most popular language used to program a PLC is ladder logic.

12


AB MLX 1400 PLC

In our conveyor example in the “PLC example system” section of this CD, we had several different “requirements” that we needed to accomplish. This included things like timing and counting parts on the conveyor. Each of these requirements must be programmed into the PLC so that it knows how to respond to different events.

In most cases today, a programmer will use a personal computer and the associated PLC programming software to create a program. The

13


AB MLX 1400 PLC

programmer will connect their personal computer to the PLC through a network or cable and then download the program to the PLC.

LADDER LOGIC

Here, we can see an example of ladder logic. Each line of code is known as a “rung”. In this example there are 4 rungs, numbered 0, 1 and 2, and the end rung marking the end of the program.The PLC executes the program 1 rung at a time, starting with the first rung and then working down. Each individual rung is executed from the left to the right. Therefore, you typically find the inputs on the left and the outputs on the right. Ladder logic rungs are basically if - then statements. If the input conditions are true, then command the outputs based on a true input. If the input conditions are false, then command the outputs based on a false input.

14


AB MLX 1400 PLC

Let’s take a look at a sample rung. The first instruction is known as an “XIC”, which stands for “examine if closed”. This is an input instruction.

This instruction checks to see if the input assigned to this instruction is on and then sets the rung to true if it is. If the input is off, then the rung will be set to false. If there were multiple XIC’s on the rung, then all would have to be on for the rung to be true.

This instruction checks to see if the input assigned to this instruction is on and then sets the rung to true if it is. If the input is off, then the rung will be set to false. If there were multiple XIC’s on the rung, then all would have to be on for the rung to be true.

All the inputs have to be on for the rung to be true

The second instruction is known as an “OTE”, which stands for “Output Energize”. This is an output instruction.

This instruction turns on the output assigned to this instruction if the rung is true. If the rung is false, then the output will be turned off. If there were multiple OTE’s on the rung, then all would be turned on or off based on the rung condition (true or false).

15


AB MLX 1400 PLC

All the outputs will turn on if the rung is true

Therefore, this rung literally reads as: “If the Start Button is on then turn on the motor. If the Start Button is off, then turn off the motor”.

OTHER PROGRAMMING LANGUAGES

While ladder logic is the oldest and most popular language used in PLCs today, many other languages are gaining in popularity and are in wide use. Examples are:

• Sequential Function Chart (SFC).

• Function Block

• Structured Text

• Higher level languages such as C.

• SEQUENTIAL FUNCTION CHART (SFC).

16


AB MLX 1400 PLC

• FUNCTION BLOCK

• STRUCTURED TEXT

• HIGHER LEVEL LANGUAGES SUCH AS C.

HMI (HUMAN MACHINE INTERFACE)

17


AB MLX 1400 PLC

These allow control systems to be much more interactive than before. The basic purpose of an HMI is to allow easy graphical interface with a process. These allow an operator to use simple displays to determine machine condition and make simple .The most common uses are,- display machine faults- display machine status- allow the operator to start and stop cycles- monitor part counts settings.

DESIGN CASESDesign an HMI for a press controller. The two will be connected by a Devicenet network.

A PLC With Connected HMI

• The common trend is to adopt a user interface which often have,

- Icons- A pointer device (such as a mouse)- Full color- Support for multiple windows, which run programs simultaneously- Popup menus- Windows can be moved, scaled, moved forward/back, etc.

• The current demands on user interfaces are,

- on-line help- adaptive dialog/response- feedback to the user- ability to interrupt processes

18


AB MLX 1400 PLC

- consistent modules- a logical display layout- deal with many processes simultaneously

• To design an HMI interface, the first step is to identify,

1. Who needs what information?2. How do they expect to see it presented?3. When does information need to be presented?4. Do the operators have any special needs?5. Is sound important?6. What choices should the operator have?

ADAVANTAGES- colour coding allows for easy identification (eg. red for trouble)- pictures/icons allow fast recognition- use of pictures eases problems of illiteracy-screen can be changed to allow different levels of information and access

• The general implementation steps are,

1. Layout screens on PC based software.2. Download the screens to the HMI unit.3. Connect the unit to a PLC.4. Read and write to the HMI using PLC memory locations to get input and update screens.

DRIVE BASED BACK UP MEMORY• The drive based ADR is done through the memory module. The memory

module is based on EEPROM technology, and is good for 100,000+ write cycles.

• All configured tags are stored in the memory (when drive is not in run mode).

27


AB MLX 1400 PLC

• Any tags that get changed via Ethernet during runtime are not written to memory module.

KEYPAD• The Kinetix 300 drive is equipped with a diagnostic LED display and three push

buttons that are used to select displayed information and to edit a limited set of parameter values.

• Parameters can be scrolled by using the “UP” and “DOWN” buttons.

28


AB MLX 1400 PLC

• To view a value, press “Enter” . To return back to scroll mode press “Enter” again.

• After pressing the ”Enter” button on editable parameters, the yellow LED “C” will blink indicating that parameter value can be changed. Use “UP” and “DOWN” buttons to change the value.

• Press “Enter” to store new setting and return back to scroll mode.

STATUS DISPLAY BEHAVIOR• By default, if there is no activity on the input keypad for 30 seconds, the Kinetix

300 drive continuously scrolls the drive’s IP address.• Upon power up, the display shows its status: “diS” (disabled) or “run” (enabled),

then after 30 seconds, the drive alternately scrolls the drive’s IP address along with its status.

29


AB MLX 1400 PLC

• If the Kinetix 300 is faulted, the drive displays the fault code (non-scrolling). Then after 30 seconds, the drive alternately scrolls the drive’s IP address along with its fault code.

SAFE OFF• The Kinetix 300 has an ISO 13849-1 Safety Category 3 Performance Level d,

compliant safety circuit. • Safety functionality is implemented to allow the drive output to the motor to be

disabled so that the drive cannot generate torque in the motor. • 6-pin quick-connect terminal block for the safety function interface.

30


AB MLX 1400 PLC

SAFETY BYPASS WIRING

If Safe Off is not used, the safety circuit must be wired to bypass the safety function, as shown above.By default, the Safe Off is NOT bypassed

ANALOG INPUTS

• Analog Reference Input– The analog reference input accepts up to a ±10V analog signal across AIN1+ and AIN1-. – The analog signal will be converted to a digital value with 13 bit resolution (12 bit plus sign). – If used in single-ended mode, one of the inputs must be connected to a voltage source while

the other one must be connected to Analog Common (ACOM).

31


AB MLX 1400 PLC

– If used in differential mode, the voltage source is connected across AIN1+ and AIN1- and the driving circuit common (if any) needs to be connected to the drive Analog Common (ACOM) terminal.

ANALOG OUTPUT

• Analog Output– The analog output is a single-ended signal (with reference to Analog Common (ACOM)) which

can represent the following motor data:– Not Assigned – RMS Phase Current– RMS Peak Current– Motor Velocity– Phase Current R– Phase Current S– Phase Current T– Iq Current– Id Current

• The analog output resolution is 10 bit, and supplies a maximum of 10 mA from -10 to +10 VDC

DIGITAL INPUTS• The Kinetix 300 has twelve digital inputs that can be utilized by the drive.

Example uses includes travel limit switches, proximity sensors, push buttons and hand shaking with other devices. Each input can be assigned an individual de-bounce time via tags.

32


AB MLX 1400 PLC

• Some inputs can have additional special functionality such as Travel Limit switch, Enable input, Homing, and Registration input and can only be used on certain digital inputs as shown below:

The inputs listed as Not Assigned are configurable to be any of the following inputs:– Abort Homing– Start Homing– Home Sensor– Start Index– Abort Index– Reset Faults
