Set coil: When the value ‎TRUE‎ arrives at a set coil, the coil retains the value ‎TRUE‎. As long as the application is running, the value can no longer be overwritten here.

Reset coil: When the value ‎TRUE‎ arrives at a reset coil, the coil retains the value ‎FALSE‎. As long as the application is running, the value can no longer be overwritten here.

You can use the “FBD/LD/IL  Set/Reset” command to define an inserted coil as a set coil or reset coil, or insert it as a “Set Coil” and “Reset Coil” element from the “Tools” view.
