Hello all,
Just airing this out to see if I've missed any trouble shooting step.
This is for PLC5 DeviceNet Scanner.
My module is the AB 1790D-T8BV8B, I set it to address 20 using the wheel, reset it. I see it when I scan channel A. But it has a solid red light under the NET LED. I check the scanner and there is no error code flashing anything above 63. it only flash the number of the node that are not connected, 20 is one of it.
I scan all 4 channels, A,B,C, D and 20 is only on A.
Does indicates a wiring problem according to the manual. Is there anything else I can try ?
I can't measure resistance on the line as I have to power down the scanner at the PLC
