132 Using High-Speed Outputs
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:
The Done (DN) bit becomes true (1) when the PTO completes and
remains set until the PTO rung logic is false. The false rung logic
re-activates the PTO instruction. To detect when the PTO instruction
completes its output, monitor the done (DN) bit.
