Hello,
I have an Anybus 7702-B / MB100 that I am interfacing to a Modbus RTU RS485 Gateway. I have verified data output from my RS485 Gateway up to the Anybus with Modscan32.
I have configured the Modbus settings of the Anybus to match those of the Modbus RS485 gateway and the settings used for Modscan, but I do not get a Serial Link light on the Anybus. I have attached screenshots of the configuration here. Swapping polarity of the RS485 A and B signal lines and using a 120ohm termination resistor has had no effect.
