Any Mitsubishi communication module, not listed above, that supports Mitsubishi Melsec Communication (MC) protocol should also work with the driver.

Fernhill SCADA Mitsubishi Melsec Tags

The Mitsubishi Melsec driver provides these tag types to support communication with Mitsubishi Melsec PLC Devices:

IconTag TypeVersionDescription
Channel IconMitsubishi Melsec UDP Channel Tag1.1 A connection to a Mitsubishi Melsec device using MC Protocol over UDP.
Channel IconMitsubishi Melsec TCP Channel Tag3.71 A connection to a Mitsubishi Melsec device using MC Protocol over TCP/IP.
Channel IconMitsubishi Melsec Serial Channel Tag1.1A serial port used for Mitsubishi Melsec serial communications.
PLC Device IconMitsubishi Melsec PLC Tag1.1 A Mitsubishi Melsec PLC or communications module.
Register Block TagMitsubishi Melsec register block1.1 A block of registers read from a Mitsubishi Melsec PLC.

To configure a connection to Mitsubishi Melsec PLC, do the following:

  1. Create and configure one of the following Channel Tags: Choose the channel tag based on how you want to communicate with the PLC.
  2. Create and configure a Mitsubishi Melsec PLC Tag.
  3. Create I/O Data Point Tags to represent data in the PLC Device. For each I/O Data Point Tag you create:

The Serial Device Configuration Walkthrough provides step by step instructions on configuring tags manually.

Fernhill SCADA I/O Data Point Tags

You can use these I/O Data Point Tags to represent individual data points in the PLC:
