Modifying Cycle Timer to Ignore Downtime

Now we can modify our CYCLE timer so that it does not run when the machine is down for any reason. We do this by modifying the Start Condition to check that the "OK to Run" timer is running. The variable in MDC-Max for this is TIMERRUNS[timername] and it returns True (timer is running) or False (timer is not running).

Highlight the CYCLE timer and modify the start condition as follows:

Notice the use of AND in the expression:

This makes sure that the cycle timer will only start when it receives a CYCLESTART message from the machine AND the OKTORUN timer is running.
