How to Use the Step Ladder Program Block Appendix A
Example of Step Ladder Program
Note A contact ITEM that has been turned ON by the OUT command stays ON even if program execution
moves to the next STEP. For this reason, care must be taken when using the OUT command when per-
forming step progression control. To turn OFF the contact ITEM, that has been turned ON by the OUT
command, by movement between STEPs, use the RESET command to reset the contact ITEM.
