Communication Between a Quantum Master and Momentum Slave using Modbus

Posted by Dallas on 7 August, 2008 - 12:53 am

I am currently working on a PLC project. I would like to establish a master and slave communication using Modbus protocol. I would like the Quantum (master) to talk to Momentum (slave) via Modbus. But I have little experience with Modbus. The PLC software I use is Concept v2.2. Please, could someone help with some tips and an example of the code for this communication?
