Hi,

I'm to connect a MC403 controller to an existing network as a slave and simply retrieve some data from the VR. 

Existing network is a RS485 two wire with a plc as the master reading data from three ABB drives. Thinking about connecting before the drives (physically easier).

Question, is it possible, can only find info on Modbus RTU clients and if so does anybody have any "pointers"  ;).
