Sample Program
You may refer to the sample structured text program WALLCLOCK.ST to update
the module’s wallclock after powerup. After power up the module will not perform
time-of-day scheduled operations until it receives a valid wallclock value (date
and time) from the Quantum processor. During this, the module will set the
following register from the Supervisory Input block to 1 until it receives the
walllclock from the Quantum:
