Test the TONOFF Predefined Function
The TONOFF instruction starts an internal timer up to a given value PT when
input IN makes a transition from low to high, and energizes the output when
ET = PT.
Restart the internal timer up to a given value PTOF when input IN makes a
transition from high to low, and de-energize the output when EP=PTOF. To test
the operation, we connect a push button to I03, and a pilot light to output O01.
