I've been a controls engineer for decades.
RSLogix 5000 for Allen-Bradley Logix line of PLCs (or PACs - Programmable Automation Controller) has a special folder called "Controller Fault Handler". This is for special code that, surprisingly enough, is for CATCHING major faults (i.e. not if a sensor isn't acting correctly, but if, say, a whole input module is dead), then handling the fault in an, hopefully, orderly fashion, such as shutting the machine down gracefully if possible.
Siemens does the same thing with special Function Blocks
