Hi, I am try as first time to work with this type of relay (BE1-951 OPS-Overcurrent Protection System) and using Modbus protocol.
I can communicate with device and read some holding registers function code 3.
I can write also some setting to relay using function code 6 and 16.

If I want to switch some contact output on relay via line command as an example using virtual switch I do so: ACCESS=951 To get the global access and I write the command CS-43=1 to select the switch and CO-43=1 to operate the switch and close the output relay, but to do this via Modbus I can not only I am able to select but to operate I can not.

Somebody cane assist please.
