Name	Type	Description
fY	REAL	Control value
fYMin	REAL	Minimum control value
fYMax	REAL	Maximum control value
fW	REAL	Setpoint
fX	REAL	Process value
fE	REAL	Displays the control deviation of the sequence controller. This depends on the control direction of the respective sequence controller. E_BA_Action.eDirect -> fE = fX-fW E_BA_Action.eReverse -> fE = fW-fX
nActvSeqCtrl	UDINT	Number of the active sequence controller.
nMyNum	UDINT	My number in the sequence.
eActn	E_BA_Action	Controller control direction
bSeqCtrlOperable	BOOL	The sequence controller is ready to operate.
bWatchdog	BOOL	The watchdog is set at each PLC cycle in each sequence controller and reset after evaluation in the sequence link.
bSeqNumMultiple	BOOL	Indicates that the own sequence number nMyNum has been assigned multiple times to sequence controllers.
bEn	BOOL	Input Enable sequence controller
bIsActvSeqCtrl	BOOL	Indicates that the sequence controller is the active one in the sequence.
