FB_BA_MV

The function block FB_BA_MV represents the Multi-State_Value object.
It has a priority array and can therefore be commanded (see Commanding objects).

The Multi-State_Value object specifies an object type whose properties represent externally visible characteristics of a virtual data point for a "Multi-State Value". The Multi-State_Value has no I/O hardware in the associated Device object, it is stored in memory.

Outputs

Name	Type	Description
nPresentValue	UDINT	Current value for multi-stage outputs.
eActivePrio	E_BA_Priority	Active priority

Inputs CONSTANT PERSISTENT

Name	Type	Description
nDefaultValue	UDINT	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.
aStateText	T_BA_StateTextArray	The array is used to declare the state texts of a multi-state object.
aAlarmValues	ARRAY [1..BA_Param.nMultistate_StateCount] OF UDINT	Within the array the states of the multi-state object are described for which an alarm is present.
aFaultValues	ARRAY [1..BA_Param.nMultistate_StateCount] OF UDINT	Within the array the states of the multi-state object are described where an error is present.
bEnManualRm	BOOL	Enabling the "Manual Remote" priority.
nValManualRm	UDINT	Variable for writing a value to the "Manual Remote" priority.

VAR

Name	Type	Description
