LMC058LF42 Schneider PLC to Kepware Kepserver

[pssriram16]

I am working on code to send some data from LMC058LF42 Schneider PLC to our factory database using kepware kepserver as the OPC server. In order for Kepware Kepserver to connect to LMC058LF42 Schneider PLC via Modbus/IP looks like it needs access to the internal registers. I am not sure how to identify the internal registers to the corresponding Global variables. Anyone have experience with connecting a Schneider PLC to OPC server?

configure variables to use modbus with AT %MW0, AT %MW1... command after variable names on Codesys

Hi Lare,
One of the suggestions I received is to add a Modbus slave device inside the PLC Somachine software and map the global variables to Modbus holding registers. I have not tested this yet.
