Dear colleagues. I need your wise help for a problem with a network of cj1w-clk21 and cj1w-clk23.
I'll explain.
Normally this network worked well, without any problems, but after adding 3 more machines to the network, every time the electrical panel of one of the machines was turned off, the communication stopped working, something that previously did not happen. I've already checked all the programming and everything is fine, because after reestablishing communication, there is no problem with the network.
How do I reestablish communication.
It was the last communication letter and I disconnected the final resistance terminal, then immediately connected the terminal again and everything started working normally again.
Can anyone tell me a way to fix this or maybe even know why this happens???
