Operating conditions for the Step Ladder Program block
The operating conditions for the Step Ladder Program block vary according to the startup mode of ITEM006.
You can specify one of the following:
• Operation at all times
• When S1 turns ON
Note The Step Ladder Program can be started up from other Step Ladder Program blocks by BLOCK SET.
When a single step is used as a logic sequence
The default step is STEP000. STEP000 operates at all times when the operating conditions are satisfied. This
step operates when run/stop command S1 (ITEM008) of the Step Ladder Program block turns ON.
