
Master Control Relay
When the master control relay closes depends on the trigger type:
For Internal Part Trigger, it closes when the Part Finding Sensor is true.
For External Part Trigger, it closes when the trigger input is set and the
Part Finding Sensor (if used) is true.
The master control relay is only present in Free Running mode if a Part
Finding Sensor is used, and it is closed when the sensor is true.
Rungs
A rung is true if a path exists across the rung that passes only through
closed contacts. A contact is closed when the sensor or coil that is
assigned to it is true. An inverted contact is closed when its assigned
sensor or coil is not true.
You can tie logic results to discrete output lines, or you can assign them
to contacts on other logic rungs.
