I have faced an issue after turning on the Control system which was in shutdown for a long period.The Control system failed to restart showing error connecting to I/O pack <R>. On observation it was found that the < R>I/O pack of an Analog I/O card was not communicating with the switch. On replacing the I/O pack with a new one similar problem was observed on this new I/O pack. However, the I/O pack was operating perfectly on the <S> slot of the I/O card. So, the I/O board was replaced with a new one.
After installation of this new I/O card and packs we faced the same error of communication issue.
The problem was resolved after going into the card and selecting the modify option wherein the barcode number of the new card is to be selected from the available option in the dialog box.After then building and double downloading solved the issue.
