Mitsubishi FX Ethernet Driver

Mitsubishi FX Ethernet implements the MELSEC-F (or MC) communication protocol that can be used with FX CPUs as described in the Mitsubishi document “FX3U-ENET USER’S MANUAL”, chapter 8 “Communication using MC protocol”. NOTE: Mitsubishi FX3U controller must be equipped with the appropriate Ethernet module: FX3U-ENET

Document code ptn0365 Version 1.01

Protocol Editor Settings

Add [+] a driver in the Protocol editor and select the protocol called “Mitsubishi FX ETH” from the list of available protocols.

Figure 1

IP address Ethernet IP address of the controller

Port Specifies the port number (decimal) used in the communication with the PLC.

PLC Model Defines the PLC model connected

PLC Network The protocol allows the connection of multiple controllers to one operator panel. To

set-up multiple connections, check “PLC network” checkbox and enter IP Address for all controllers.

Tag Editor Settings

Into Tag editor select the protocol “Mitsubishi FX ETH” from the list of defined protocols and add a tag using [+] button. Tag settings can be defined using the following dialog:

Figure 3

Resources Area of PLC where tag is located

Offset Offset address where tag is located.

SubIndex This allows resource offset selection within the register.

Type Data Type Memory Space Limits

boolean 1 bit data 0 ... 1

byte 8-bit data -128 ... 127

short 16-bit data -32768 ... 32767

int 32-bit data -2.1e9 ... 2.1e9

unsignedByte 8-bit data 0 ... 255

unsignedInt 32-bit data 0 ... 4.2e9

float IEEE single-precision 32-bit floating point type

1.17e-38 ... 3.40e38

string Refer to “String data type chapter”

NOTE: to define arrays, select one of Data Type format followed by square brackets like “byte[]”, “short[]”…

Arraysize When configuring array or string tags, this option define the amount of

array elements or characters of the string.

Tag Import

The Mitsubishi FX Ethernet tag import accepts symbol files with extension “csv” created by the Mitsubishi GX Works2 (Not from GX Developer). The “.csv” file can be exported from the Project tree, as shown in Figure 4.

(1) Right-click on the Global variable list that need to be exported, (2) Select “Write to CSV File…”

Figure 4

Into following dialog select the file name and location:

Figure 5

Once exported, open JMobile tag editor as in shown in Figure 6, then:

(1) Click on Import button (2) Confirm Controller and Import Type

Controller Settings with GX Developer

The Mitsubishi FX system must be properly configured for Ethernet communication using the Mitsubishi FX Configurator. Click on “Operational settings” as shown at point (1) in Figure 8:

Figure 8

Into Operational Settings dialog, verify the “Communication data code” is set to “Binary code”, Then type-in the Controller IP Address and confirm with [End] button.

Figure 9

Click now on “Initial settings” as shown at point (2) of Figure below:

Figure 10

For proper communication between HMI and controller it is required to change “Destination existence confirmation starting interval” from the default value of 1200 to 10ms.

Figure 11

In case of communication error, this avoid controller keeps alive the connection for a too long time before to allow a new connection from the HMI.

Click now on “Open settings” as shown at point (3) of Figure below

Figure 12

Figure 13 shows the “Ethernet open settings” configuration. The detailed explanation of the meaning of each setting is available in Chapter 5.5 of the Mitsubishi “FX3U-ENET USER’S MANUAL”. “Host station Port No.” defined here is the same must be used into Protocol Editor Settings chapter.

Figure 13

NOTE: the usage of more than one panel communicating with the same controller requires to define proper settings in the “Open settings” configuration dialog: one connection per each panel must be configured with proper properties.

Controller Settings with GX Works2

The Mitsubishi FX system must be properly configured for Ethernet communication inside GX Works2 programming suite. FX Parameter dialog can be recalled with double-click on PLC Parameter:

Figure 14

Then select “Ethernet Port” tab where is possible to configure IP Address. Verify the “Communication data code” is set to “Binary code” as shown below:

Figure 15

Then click on “Open Settings” button to recall the “Ethernet Port Open Setting” dialog.

Figure 16

“Host station Port No.” defined here is the same must be used into Protocol Editor Settings chapter. NOTE: For FX3GE Controller, the Open System must be set as “Data Monitor” and Port set to 1025. NOTE: the usage of more than one panel communicating with the same controller requires to define proper settings in the “Open settings” configuration dialog: one connection per each panel must be configured with proper properties.

Communication Status

The current communication status can be displayed using the dedicated system variables. Please refer to the User Manual for further information about available system variables and their use. The codes supported for this communication driver are:

Error Notes

NAK Returned in case the controller replies with a not acknowledge

Timeout Returned when a request is not replied within the specified timeout period; ensure the controller is connected and properly configured to get network access

Invalid response The panel did receive from the controller a response, but its format or its contents is not as expected; ensure the data programmed in the project are consistent with the controller resources

General Error Error cannot be identified; should never be reported; contact technical support
