■Advance function
In the AUT mode, this function block proceeds to the next step by forcibly ending the step in execution.
This function is executed on the rising edge of the input variable ADVANCE command and proceeds the processing by one
step. To proceed the processing by one step next time, turn off the command and then turn it on again.
Setting value (SV)
Skips the remaining time.

When the advance command is executed in the waiting status, the status is cleared and the processing shifts to the one of the
next step.
When the advance command is executed at the last step, the control will be immediately completed and the setting value
before the execution of the advance command will be held.
■Wait function
In the AUT mode, this function block checks if the process variable (PV) has followed the setting value (SV), and controls the
progress of steps every time each step is completed.
The wait width setting is common to all steps.

*1 When the time in the step was changed and the step was completed (T = Tn), the setting value (SVPGS) immediately before the change
of the time in the step is held instead of the last value of the step. To hold the last value of the step (SVn), change the time in the step to
the time immediately before the end of the step (T = Tn - 1).
