Hi,
how is the connection mode? Using ADMI tool or port RS-485?
If you are using ADMI and you are using port on board RS-485 like master, you have to disable the master because the hardware port is the same.
If you are using ADMI or RS-4885 on board check the communication BIOS parameter CF30, CF31, CF32, using the BIOS menu navigation on keyboard and display.
If you are using LAN port in modbus check the communication BIOS parameter CF35, CF36, CF37,using the BIOS menu navigation on keyboard and display.
Best regards
Marco Cervati
