Hello @SaurabhShukla ,
May I ask what a custom OPCPublisher module is? On what is this module based? Did you follow the Tutorial: Deploy the OPC Publisher?
If you deploy a module on IoT Edge, you also need to declare a route. To inspect your OPC Publisher Module and messages send to the cloud from IoT Edge, you can view the logs of the edge modules on your device and the message passing the IoT Edge hub.
