Modules connected to cpu PM783F have error
Modules connected to cpu PM783F have error although the module connected to the same cpu through Profibus is OK.
After CPU restart (Hardware or software ) the modules return to normal status.
Those red led's are for group channel error indication.
Check few things
All physically not connected channels configure it as "unused", specially analog one.
Also check supply voltage is above required threshold voltage.
Note if all the 4 CHErr led continuous light up red it is module error some internal error. but if it's blinking then there is some issue in one of the channel in that group of channels.
From the images you have shared seems on DC 732 might have module error.
Btw after CPU restart error gone permanently or it appears again ?
