Supported hardware and software

The MELSEC Communication Driver enables Ethernet and serial communication with Q, QnA, L, and the iQ-R-series PLCs from Mitsubishi Electric, using the MELSEC protocol.

To program these PLCs, you need to use the GX Developer, GX Works2, or GX Works3 programming software from Mitsubishi Electric.

Device Configuration

The support PLCs communicate over both UDP and TCP ports.

The Communication Method for:

• Q-series PLCs is the MC protocol (MELSEC Communication Protocol)

• iQ-R series PLCs is the SLMP protocol

  Notes: It is necessary to configure the Destination IP Address when communicating over UDP/IP.
