ETHUB18 How do I poll multiple channels via tcp server? For example I have 2 modbus networks one has 6 slaves id 1 to 6, and the other 4 slaves ids 1 to 4. How do I specify what channel to use? Do I need to set up different ports?
Answer:
This is an Ethernet to RS485 HUB. All ports of the HUB share the same bus.
