Instruction Behavior

The PLS instruction behaves as follows:

  • When the execution condition goes from OFF to ON, the assigned data register, D, turns ON for 1 scan.
  • When the execution does NOT change states or changed from ON to OFF, then the assigned data register, D, does NOT turn ON.
  • Even if the RUN/STOP key switch is changed (STOP→RUN) after the execution of the PLS instruction, the instruction will NOT be executed again until the proper change of state of the executing statement from OFF to ON occurs.
