Hi Dekor
I have two PLC with same data's. And in one PLC i have a problem, but i didn't know the exact reason. And for that i took modules from the PLC that has work.
After i see that both modules have the same problem, i look elsewhere and i find the problem. After that i install modules in their places. In the first PLC i have a EPROM with program on it, and i go in over all restart, and after that the PLC start to work, but on second PLC that has work very good until i take their modules, when i install modules i have the alarm on St and BASP and machine hast stopped.
I have checked for modules again if they are in their places but nothing happened.
Thank in advance.
