Hello Armin,
the NIOT-Gateway came to my desk today. To transfer the OPC Server was made in the blink of an eye.
Next to do is the setup of the MODBUS-Interface. Here I'm feeling a little bit lost. MODBUS. The standard defines addresses for the slaves. So, if I cannot set a address to the MODBUS-nodes, does this mean, that the NIOT and the netPI are always the server?
Second, very confusing thread is, that the LEDs on the RS485-NPIX do not automatically reflect the corresponding state of the interface.
Do you have a working example for MODBUS RTU RS485 communication?
Looking forward a brighter future,
Carsten
