Time monitoring function:
Starts timing when execution condition A goes
ON. Generates a non-fatal error if output B
isn't turned ON within the monitoring time.
Diagnoses a failure in an instruction block by monitoring the time
between execution of FPD(269) and execution of a diagnostic output
and finding which input is preventing an output from being turned ON.
