5.1 Device Object
The following properties are supported in the Device Object (available for all pump types).
Property identifier Data type Notes Access
Object_Identifier BACnetObjectIdentifier See section Selecting the Device Object Instance Number. R
Object_Name CharacterString
See section Selecting the Device Object Name for details on
object name.
W
Object_Type BACnetObjectType DEVICE. R
System_Status BACnetDeviceStatus OPERATIONAL. R
Vendor_Name CharacterString Grundfos. R
Vendor_Identifier Unsigned16 227. R
Model_Name CharacterString
Will show the Grundfos pump model to which the CIM/CIU
module is connected.
R
Firmware_Revision CharacterString Revision of the firmware in the CIM/CIU module. R
Application_Software_Version CharacterString Software build date, DD-MM-YYYY. R
Location CharacterString
The user can enter a location here (maximum 200
characters).
W
Description CharacterString
The user can enter a description here (maximum 200
characters).
W
Protocol_Version Unsigned Actual version of the BACnet protocol. R
Protocol_Revision Unsigned Actual revision of the BACnet protocol. R
Protocol_Services_Supported BACnetServicesSupported
Indicates which standardised protocol services are
supported.
R
Protocol_Object_Types_Supported BACnetObjectTypesSupported
Indicates which standardised protocol object types are
supported.
R
Object_List
BACnetARRAY[N]of
BACnetObjectIdentifier
An array of objects available. R
Max_APDU_Length_Accepted Unsigned
CIM 300: The maximum number of bytes that may be
contained in a single APDU. Fixed to 480.
CIM 500: The maximum is 1476.
R
Segmentation_Supported BACnetSegmentation
Indicates if segmentation of messages is possible. Will
always read NO_SEGMENTATION to indicate that
segmentation is not possible.
R
APDU_Timeout Unsigned Indicates the amount of time in ms before time-out. R
Number_Of_APDU_Retries Unsigned Maximum number of times an APDU is to be retransmitted. R
Max_Master Unsigned
Specifies the highest possible address for master nodes and
must be between 1 and 127.
The default value is 127, but this value can be lowered by the
user to reduce transmission overhead.
W
Max_Info_Frames Unsigned
Specifies the maximum number of information frames that
are sent before the token is passed on. Fixed to 1.
R
Device_Address_Binding List of BACnetAddressBindings Holds address bindings to other devices, if any. R
