Input Description

EN (enable)

Data_Type	Default_Value	Range	Unit
BOOL	FALSE	-	-

In order to enable the function block processing, input EN has to be continuously set to TRUE. The function block is not processed if input EN = FALSE. While input EN is set to TRUE input IN is evaluated and used to update BACnet object property Present_Value.

OBJ_ID (object ident number)

Data_Type	Default_Value	Range	Unit
WORD	0	0…4194302	-

Defines the BACnet object ident number. The object ident number has to be unique within the BACnet network.

OBJ_NAME (object name)

Data_Type	Default_Value	Range	Unit
STRING(40)	Empty string	-	-

Defines the BACnet object name. The object name has to be unique within BACnet network.

UNIT

Data_Type	Default_Value	Range	Unit
BASC_ENG_UNITS_ENUM	BASC_NO_UNITS	All units defined in BACnet standard.	-

Indicates the engineering unit of the Present_Value property of the object. In BACnet network the value connected to the function block input IN will be interpreted as value of this engineering unit.

IN

Data_Type	Default_Value	Range	Unit
REAL	0.0	-3.40282347E38…3.40282347E38	-

To be connected to an IEC variable representing a physical input of the Processor Module. The value will be used to update BACnet property Present_Value.
