--Scanning drawing 1020306B.CAD Trip on fault: Module 1,02,03 Block 9064 (FC 79) has S19 zero (will trip on failure).
The "trip" specification controls if the module / controller should fail over to the redundant processor if a hardware fault is found. If the trip spec is set to "trip on fault", the module will stop working. If it is set to "continue operation" on fault, the module will smoothly transfer control to the redundant module. This is the normal mode of operation.
Anytime an input / output function is found that is set to "trip on fault", it indicates that the system could be negatively impacted when it is not expected. You should make sure that there really is no redundant hardware present when you see this message.
FC 132 has its own realities. In FC 132, the block is handled as a "chain" of three blocks, controlled by the specifications of the first block in the chain. Thus, any garbage value can be in S3 of a FC 132 block with no effect, unless that block is the first one in the chain.
