I have a 1769 sdn scanner on one panel and a 1769 adn i/o module on another panel, this module got burned and replaced but after replacement scanner shows code 79 and I cannot find how to fix this.
I checked all the cables, power supply, terminator resistors and nothing.
I'm also not able to see the i/o module on the network.
Am I missing something or doing something wrong?
Any help would be much appreciated.
Thanks!
