Hi,

I have a cause & effect condition where if a LL PV Alarm is active, it needs to open a PIDConL (MV=100). Therefore, I used MV_ForOn (connected to the PV alarm)  and MV_Force(100). However, when the force condition is removed, the force value remains active (MV=100), i want it to return to the state before force. I'm thinking about MV_TrackOn but I can't use it because it was connected to my SFC Type instance block..

Hi Oreca, i tested using a 1s pulse timer, after 1s the MV_ForceOn = 0 but the output MV still equals to MV_Forced (100)

Hi,

When you first set the force value to 0.0 and a moment later set MV_ForceOn to false, I think the block will react. I think it's in the block that first the MV_ForceOn is handled and then the value is set and that is not how I would see it.

Otherwise you have to use a tracking signal -> MV_TrkOn to set the MV back to 0.0
