Hi,
i am trying to set up comms between a modicon m340 and a modicon m168 controller. I am using the mbs1 connection on the m168 to the modbus port on a p342020 modicon m340 plc. All i am trying to do is take 5 analog signals into the m168 and send the values to the m340. I am doing this because the m168 has the ability to take thermistor inputs directly into it. I will also be using the m168 to talk bacnet to 4 chillers with a bac/net mstp module. I have tried to setup the m168 to send the info to the m340, but obviously without success. I have attached the m168 program for an example...
