[WP_DATI] Write property for date and time value

Function block WP_DATI writes to a specified write property or array element of data type DateAndTime in the data point.

WP_DATI writes to a specified write property or array element of data type DateAndTime in the data point.

Functioning

Compatible data points:

Any BACnet data point with write property or array element of data type DateAndTime.

WP_DATI does not consider the BACnet object state nor the BACnet object usage.

Pins

Input	Description	Data type	Default value Value range
EnWrit	Enable write Control input that enables or disables writing of [Val] to the property or array element. If [EnWrit] changes from 0 to 1, writing occurs.	Boolean	1
Val	Value Calculated or configured value written by the control program to the property or array element. [Val] is written in the following cases: [EnWrit] = 1 and [SetUnspf] = 0 and [Val] changes. [EnWrit] = 1 and [SetUnspf] changes. [EnWrit] changes from 0 to 1. [EnWrit] = 1 and [RptWrit] = 1.	Date And Time	01.01.1990 00:00:00.000
SetUnspf	Set unspecified value Defines whether an unspecified value can be written on the property or array element.	Boolean	0
SetUnspf	0 - The value from [Val] is written. 1 - An unspecified value is written. ([Val] is ignored)
RptWrit	Repeat write Forces writing of [Val] to the property or array element. Writing is repeated in each programming cycle as long as [RptWrit] = 1. [RptWrit] typically is calculated and set by the control program. Note [RptWrit] cannot be forced permanently to 1. This may result in increased network traffic.	Boolean	0
RptWrit	0 - No action. 1 - [Val] is written to the property or array element with each programming cycle.
BaObjRef	BA-Object reference Link between function block and BACnet object.	Structure	---
BaObjRef > DeviceID	Device identifier [DeviceID] includes object type and object instance in one ID. Identifies the device object: local or remote. A local device object can also be identified by value 16#3FFFFF.	Double Word	16#3FFFFF
BaObjRef > ObjectID	Object identifier [ObjectID] includes object type and object instance in one ID. Identifies the object on a device.	Double Word	16#3FFFFF
BaObjRef > ItemID	Item identifier [ItemID] represents an index in a view node object that references the BACnet object. [ObjectID] and [ItemID] together define an indirect reference to the BACnet object. Value -1 indicates a direct interface.	Integer	-1
PrpyId	Property identifier Parameterized BACnet ID number of the property that is written.	Integer	0
ArrayIdx	Array index Index number of the array element accessed by the function block. Optional, configured input to indicate access to a property element of data type BACnetArray or BACnetPriorityArray. Cannot be changed during runtime.	Integer	-1
ArrayIdx	-1: Not used. 0: Specifies the array length of the referenced property. Note: As writing this field is not a control program function, the requirements of [ArrayIdx] = 0 are rejected by the function block. >0: Configured value.

Output	Description	Data type	Default value Value range
Dstb	Disturbed [Dstb] indicates whether the referenced BACnet object was accessed. [Dstb] = 0, if: BACnet object access = Access successful [Dstb] = 1, if: BACnet object access = Error during access	Boolean	0
ErrCode	Error code indication	Integer	0: No error
= 0 - No error > 0 - XFB error codes
