Hi,

I have an issue with AB Redundant PLC which was running perfectly for several years and all of a sudden both PLC was showing fault and stopped the plant. Any advice is highly appreciated!!
Error says- " watchdog fault-Task watch dog expired may have been caused by an infinite loop, complex program or a higher priority task

Sandy
