Hi, may this will help. At least for starting, the procedure should be similar.

> Hello all, I have experienced to read the data from 494 module under 750-362 modbus coupler from 3rd party modbus master sw/device. In my case, ı have polled the module from Modbus Poll. But if you read the document ı have shared, you will understand the method how you can implement it for another master devices. This only done with modbus but you can use same method for different special modules / couplers.
