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:

Icon Tag Type Version Description
Channel Icon Mitsubishi Melsec UDP Channel Tag 1.1 A connection to a Mitsubishi Melsec device using MC Protocol over UDP.
Channel Icon Mitsubishi Melsec TCP Channel Tag 3.71 A connection to a Mitsubishi Melsec device using MC Protocol over TCP/IP.
Channel Icon Mitsubishi Melsec Serial Channel Tag 1.1 A serial port used for Mitsubishi Melsec serial communications.
PLC Device Icon Mitsubishi Melsec PLC Tag 1.1 A Mitsubishi Melsec PLC or communications module.
Register Block Tag Mitsubishi Melsec register block 1.1 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:

Icon Tag Type Version Description
Analog Data Point Tag I/O Analog Data Point Tag 3.12 Maps an Analog Data Point Tag to an external data source.
Digital Data Point Tag I/O Digital Data Point Tag 3.12 Maps a Digital Data Point Tag to an external data source.
Word Data Point Tag I/O Word Data Point Tag 3.12 Maps a 16-bit Word Data Point Tag to an external data source.
Double Word Data Point Tag I/O Double Word Data Point Tag 3.12 Maps a 32-bit Double Word Data Point Tag to an external data source.
Long Word Data Point Tag I/O Long Word Data Point Tag 3.48 Maps a 64-bit Long Word Data Point Tag to an external data source.
