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

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

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

Create and configure one of the following Channel Tags:
Choose the channel tag based on how you want to communicate with the PLC.
Create and configure a Mitsubishi Melsec PLC Tag.
Create I/O Data Point Tags to represent data in the PLC Device. For each I/O Data Point Tag you create:
- Set the IODataSource property to the name of the Mitsubishi Melsec PLC Tag tag you created in step 2.
- Set the IOItemName property to a data item in the PLC.

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

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

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

These autodetect wizards are supported by the Mitsubishi Melsec driver:

Wizard	Description
Mitsubishi Melsec Serial	Searches serial ports for Mitsubishi PLC Devices. Supports Q-Series, QnA Series, A-Series and FX PLC Devices.
Mitsubishi Melsec TCP	Searches an Ethernet network for Mitsubishi PLC Devices using TCP/IP. Supports FX PLC Devices
Mitsubishi Melsec UDP	Searches an Ethernet network for Mitsubishi PLC Devices using UDP. Supports Q-Series, QnA Series, A-Series and FX PLC Devices
