Hello,

Is there a flag in RAPID that states if it is the first cycle after controller power on?  
Thank you!

Did you ever find anything to do with first cycle? I have a few things I need to do in first cycle only too.

Try an event routine for Power On to run a one instruction routine that sets a PERS boolean, e.g. bFirstCycleOnly, variable TRUE.

PROC rPowerON  
!  
bFirstCycleOnly: =TRUE;  
!  
ENDPROC

Be sure to change state of the PERS to FALSE in your production code.

As an idea in production code

PROC rFirstCycle()  
!  
IF bFirstCycleOnly THEN  
Stuff  
bFirstCycleOnly: =FALSE ;  
ELSE  
Return;  
ENDIF  
!  
ENDPROC
