MELSECQ Driver

The MELSECQ driver supports TCP/IP communication with the Mitsubishi Electric MelsecQ via TCP/IP, MelsecQnA via TCP/IP and Melsec iQ-R PLCs.

Note: The MelsecQ driver supersedes the MelsecQnA driver.

TCP/IP Protocol Setup

The driver will communicate with the Ethernet card in the SCADA computer using the Plant SCADA TCP/IP driver (TCPIP.DLL).

This protocol requires Winsock v1.1 TCP/IP software to be installed in your computer. This protocol does not require any software from Mitsubishi Electric.

The software needs to be properly installed before configuring this protocol. In particular, the correct values for IP address, subnet mask and default gateway need to be set before proceeding.

Note: It is recommended that you use the MELSECQ driver with a version of Plant SCADA that is fully supported in accordance with AVEVA's Software Support Lifecycle and Retirement Policy. The driver will work with Citect SCADA 7.20 or later (or a later version of Plant SCADA), however it will not be fully tested or supported on these earlier versions. Search the AVEVA Support Site Technology Matrix to determine the support status for your current version of Plant SCADA.
