Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller.
I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC.
Further I added a ModbusTCP_Slave_Device with default settings.
I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC.
Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop.
Hope anybody can help me with this, thanks in advance!
