142 Using High-Speed Outputs
structure of the control program determines when the DN bit goes off. So,
to detect when the PTO instruction completes its output, you can monitor
the Done (DN), Idle (ID), or Normal Operation (NO) status bits.
Standard Logic Enable Example
In this example, the rung state is a maintained type of input. This means
that it enables the PTO instruction Normal Operation (NO) and maintains
its logic state until after the PTO instruction completes its operation. With
this type of logic, status bit behavior is as follows:
Stage 0 1 2 3 4 5 6 7 8 9 10 11 12
