A month a go we had a problem in the CPU0 which does not pass in RUN mode ... now we decrease the causes of problems:
We isolate the CP 443-1 CPU 0 and Liasons synchronization was allowed: (Cable optic fiber, Cable Profibus) with the Second CPU1 , I switched on the Run ... the REDF LEDs start blinking in both CPU about 10s .... both CPUs are in Run mode "works" .the CPU 0 on stand by, CPU 1 Master ...
So we conclude that the CPU0 is good , the problem is either in the CP or in the rack.
-> I control the pins in the rack and the rear of the PC but nothing seems anormal all is ok.
So please we don't have piece of rechange , I want to know is what we can do ,to deduct handling if the problem is in the CP or in the Rack Or in other things that block the links?
And thank you in advance
