My understanding is that the usr LED can be used by any application. It would be handy to have a guide how to access the GPIO that controls the usr LED.
I'm trying to connect my 3 phase WAGO Power Module to measure and view 3 phase voltages, currents, etc...
Is it possible to access these parameters from the power module using the WAGO CC100? It appears that the CC100 has an onboard RS-485 input, and the Power module can transmit its data using Modbus RTU through the same kind if connection.
