A vital tag file was zeroed. The tags double integer (an array of 500) were set to zero for no apparent reason. The Controllogix plc was not faulted; however, the process was crippled. Anyone else ever experience something like this, and know a fix.
I am using a Controllogix 5555 with Ethernet communication for an OI that is reading the tags. The OI obviously has the ability to write to the tag, but is not setup to do this. I suspect AB has issues with other OI software, but don’t really know what happened. The processor is on a vital process in our facility. Any help is most appreciated.
