S800 IO-module channel error
I have a problem with the S800 AI815 IO-card. All channels are connected to the card and one of these goes to signal error. The problem is that i dont know what channel because alarm/event-list only say: channel error. I try check alarm/event details and IO-card HwStatus bits/words.
I know that channels RealIO-variable contain Status-variable and it read to control module/function block alarm handling. Signal error is very fast so it is not visible in application. Now i have created a new test single control module and I set it to fast task (50ms). I read status variable in new control module. Is this the only way to find the right channel?
