Hello everyone,
I am currently facing a challenge while trying to connect two Weintek HMI units with a Mitsubishi FX2N PLC. When connecting a single Weintek HMI using the 4-wire RS-485 interface, everything works perfectly. However, when attempting to connect a second HMI in a multi-drop configuration on the same 4-wire RS-485 interface, both HMIs seem to malfunction. I've tried changing the HMI station numbers, but the issue persists.
FX2N PLC only has a single available port. I'm seeking advice on how to successfully connect two HMIs to the FX2N PLC. Any guidance or suggestions would be greatly appreciated.
