Driver: Plant SCADA MELSECQ Driver

Version: 2.01.xx.xxx

Check the Drivers tab on the Products page at the AVEVA Knowledge & Support Center for information about driver updates and new driver pack releases.

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.

Citect SCADA 7.20 or later (or a later version of Plant SCADA) is required to use the MELSECQ 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.
