Inputs

Name	Type	Description
bEnSfty	BOOL	Enabling the "Safety" priority.
bValSfty	BOOL	Binary value for the "Safety" priority.
bEnCrit	BOOL	Enabling the "Critical" priority.
bValCrit	BOOL	Binary value for the "Critical" priority.
bEnManLoc	BOOL	Enabling the "Manual Local" priority.
bValManLoc	BOOL	Binary value for the "Manual Local" priority.
bEnPgm	BOOL	Enabling the "Program" priority.
bValPgm	BOOL	Binary value for the "Program" priority.

Outputs

Name	Type	Description
bPresentValue	BOOL	Current binary output value of the object.
eActivePrio	E_BA_Priority	Active priority.

Inputs CONSTANT PERSISTENT

Name	Type	Description
nMinimumOffTime	UDINT	Minimum time [s] in which the Present Value should remain in the INACTIVE state after a write operation to Present Value has assumed the INACTIVE state. This can be used to implement protection against too fast restarting.
nMinimumOnTime	UDINT	Minimum time [s] in which the Present Value is to remain in the ACTIVE state after a write operation to Present Value has assumed the ACTIVE state. This can be used to implement protection against premature, renewed switch-off.
bDefaultValue	BOOL	Value that is assumed if all 16 priorities of the Priority array of a commandable object have no entry or are NULL.
bEnOutOfService	BOOL	This variable sets an object out of service. It is thus OutOfService.
sInactiveText	T_BA_StateText	Text output when the object is inactive.
sActiveText	T_BA_StateText	Text output when the object is active.
bAlarmValue	BOOL	Value in the event of an alarm.
nStateChangeCount	UDINT	The variable indicates how often the state of the Present Value has changed since the date and the last reset.
nActiveTimeElapsed	UDINT	Time [s] in which the Present_Value of the object had the value ACTIVE. The time is valid from the last reset by the property Time_Of_Active_Time_Reset.
bEnManualRm	BOOL	Enabling the "Manual Remote" priority.
bValManualRm	BOOL	Binary value for the "Manual Remote" priority.
