Q Series Modbus

[John Crombie 0]

Hello All I am would like to connect a Contrec 802 blend controller to my Q02H via Modbus. As far as I know Mitsubishi doesn't make an dedicated Modbus card. Does anyone know how I might be able to interface the two? Cheers John

Look back through the topis here, or perhaps search Modbus. Someone had posted some sample code of writing a Modbus command using the no-protocol mode on the serial port or something like that a while back. If you're looking for Modbus/TCP, Mitsu now has a module for the Q series, the QJ71MT91 Modbus/TCP module. That will allow you to talk Modbus Ethenet.
