Hello,
I have trouble with multi HMI communication using Modbus RS485. I'm trying to communicate with 3 HMIs. As idea is that 1 HMI is Master device, that control 2 others, that Will power on/off lights or something like that. I have manuals how to do that, but with PLC. Is it possible to do it without PLC? I am using Weintek HMIs, one MT8070iE and two MT8050iE. Do anyone can give me some hint to solve this problem?
Greetings
