After reading through some older threads and checking out my old friend GFK-2224, it sounds like an RX3i CPU can talk Modbus TCP, this much I'm fairly confident about. But what I wonder is, if my CPU (CPE305) has just a single ethernet port, can the single ethernet port communicate multiple languages simultaneously? For example, my PLC to PLC comms are EGD. Could the CPU also, on top of EGD, communicate with a Modbus TCP device on the same network? I'm thinking no, you'd need an ETM001 module; can someone confirm or disconfirm this?
