I am working with a TGW-715 Modbus gateway which is connected to a Modbus device.
Modbus device is configured with following parameters:
And I also configured the gateway with these parameters.
I connected the D1+ and D1- of the gateway to B and A of the Modbus device.
But when I want to test if everything is working on Modbus Doctor, I got the exception code 0B which means that there was no response from slave.
I tried to increase the timeout to 3000ms but still get no response.
Do you have any idea why?
