F.0.1:5.2.2 - actuation and control output
  • Recognition cue — control theory. If actuation may mean a signal applied to plant actuators, select one exact control-theory publication, edition, and passage before using that reading.
  • Recognition cue — IEC 61131-3. If control output may mean a program-produced value sent to field I/O, identify the exact edition and clause before using that reading.

These cues establish no relation. After both readings become worked results, F.9 may test whether the PLC output can be read as the controller’s actuation signal for one stated operating regime while keeping hardware and scan-cycle limits visible.
