Communicating Citect Scada with Mitsubishi IQR series PLC

Puru

Hi team,

We were trying to communicate Mitsubishi IQR PLC with Citect Scada using Melsec Q driver.

As we were not successfull in establishing the same .

Kindly share sample backup or settings required at Citect end or in Mitsubishi software to establish the communication.

Thanks in advance.

Regards,

Puru

  • I have been working with the Mitsubishi iQR product, but I abandoned the internal Melsec Q driver in favour of the OPC Driver and Mitsubishi's own OPC Server OPC MX UA. This worked great.

    The Melsec Q drivers are very old and do not support the larger addresses spaces the iQR supports (well outside the 16bit address range of the Melsec Q protocol).

    Mitsubishi have an internal (private) protocol they use between their PLCs and their OPC server which is far more efficient in the amount of data that can be transferred in one transaction.
