Issue:
R_TRIG, F_TRIG, TRIGGER, TON, TOFF, and TP function blocks usage in first PLC section


Product Line:
Quantum HSBY


Resolution:
No. R_TRIG, F_TRIG, TRIGGER, TON, TOFF, and TP function blocks cannot be used in Section 0 (First PLC section) of a HSBY system because their use can lead to unintended changes in state at switchover. Section 0 is the only section solved by a Standby System and is updated at the end of scan by the Primary.
