An issue occurred at an organization here in whereby the ControlNet card developed a fault.
Card Details:
Catalog/Series; 1756-CN2RXT B
Part No; PN-30150
The A & B lights on the card were solid green and the OK light was blinking green with a display showing OK. The card was showing Status: Running in RSLogix 5000.
However, all the the Flex I/Os connected to the card were showing Status: Faulted in RSLogix 5000.
Upon soft reset of the bridge card, the system began to work fine. However, significant damage had been done and critical I/Os were tripped.
Please advise on what could have happened and what can we do to prevent it from happening in the future.
