f) Step synchronized output
The code that is specified in the step being executed is output to the external control I/O connector.
However, “0” is output during a normal output step.

g) Step end phase setting
When the step end phase is set as enabled, the step execution time is as described below.
The step execution time = Set step time + Time for superimposed AC phase to become 0 
After the set step time elapses, the setting for that step is retained in the subsequent operation.
