I am very new when it comes to programming thing using a Prosoft card using Modbus. I am fine to figure that out by studying the manual. However I cannot seem to find good information on what kind of hardware I will need to get the two devices to talk to each other. We have a similar system with a SLC rack that uses a rs232 to rs485 converter (isolated i believe, it has its own power source) and then two wire 'daisy chain' to each of the devices. I am just trying to get my foot in the door with testing communicating over modbus with a single device for the time being before getting any permanent wiring.
