Review the following information for setting up and configuring the Mitsubishi F Ethernet driver.

Litmus Edge Compatible Series

Compatibility parameter	Compatible items
Driver type	Ethernet
Validated devices/series	MELSEC-F Use this driver to connect to the built-in Ethernet port on the CPU or FX3U-ENET modules. When connecting to an FX3U-ENET module, the Station ID must be set to the default value of 255 or the setting must be absent in GXWorks2 or FX Configurator-EN.

To set up and configure this device in Litmus Edge, you will need to do the following:

Step 1: Set up and Configure the PLC Device

Step 2: Set up the PLC Device in Litmus Edge DeviceHub

Step 3: Configure the List of Registers

Step 1: Set up and Configure the PLC Device

Note: Only one connection is allowed per port defined in the PLC. See the steps below to view and edit the open ports on the PLC.

If the device is configured for Ethernet access, find its network parameters. Otherwise, follow the steps below.

To configure your device:

Note down the following information and refer to it as needed.

Device: Mitsubishi FX3GE-24M

Communication I/F: Ethernet. Refer to the following figure.

Reference image of device

Connect the device to your pc using USB and launch the GX Works 2 v1.560J software.

Click Online > Read from PLC.

Select PLC series.

Set up the connection.

Click Connection Test.

From the Navigation panel, click Parameter > PLC Parameter > Ethernet Port.

From the Navigation panel, click Connection Destination > connection1.

Double-click PLC Module , click Search for FXCPU on network, and then select the target device.

Click Connection Test.

Step 2: Set up the PLC Device in Litmus Edge DeviceHub

Configure the following parameters when you Connect a Device with this driver. Update default values to the specific setup of your device.

Parameter	Value
Type	Mitsubishi
Driver	Mitsubishi F Ethernet
Network Address	The device address you defined in Step 1
Port	5001

Step 3: Configure the List of Registers

When you Add a Tag to the connected device, see the following Register Table and Tag Parameters sections. See the following additional resources if necessary:

Tag Parameters

Name: Select a register name from the drop-down list. The available options depend on the names in the register table.

Value Type: Select a data type from the drop-down list. The available options depend on the register name selected.

Polling Interval: Enter a value in seconds. This determines how often the tag should poll the register for data.

Tag Name: Enter a name for the tag.

Description (Optional): Enter a description for the tag.

Address: Enter a tag address. The value must in the decimal format, within the allowed min/max range. Omit the leading zeros. The device might use the decimal (D), hexadecimal (H), or octal (O) address format. See the Register Table at the bottom of the dialog box. For Bit tags, append the bit address without the bit separator. The lowercase letters in the address format indicate how many digits you should enter in the Bit address.

Tag Formula: Enter a formula for the tag to process the generated data. Two variables are permitted: value (current tag value) and timestamp (current tag UNIX time in milliseconds). The following math functions are available:

sqrt

power: power(x) performs the operation 10^x.

log: log(x) is the natural logarithm (the logarithm is in base e).

exp: exp(x) performs the operation e^x.

Only Publish on Change of Value: Select the checkbox to only publish NATS messages when the value parameter changes to a new value. Change of Value only applies to boolean, numeric (such as int or float), and simple string data types. It does not apply to complex types, such as JSON or array. Poll-once topics will not be affected by Change of Value settings. These topics will still only see a single message.

Meta Data: Metadata summarizes basic information about data. This feature allows you to define key-value pair data for the device output payload later on. Metadata can then be used to find, use, and reuse particular instances of data.

Note: If you use special characters in meta data key names, the special characters are replaced with underscore characters in the payload. This can cause two key names to be combined into one. For example, configuring the key names a**b and a&&b will cause only one key name to be created (a__b).
