Product Description: 

The UK24BAC device is a gateway from MP to BACnet MS/TP. Up to eight MP-bus-capable 
Belimo actuators can be connected on the MP-Bus side. This permits the actuator functions as 
well as the connected sensors to be integrated directly into BACnet. 
The datapoint mapping from MP to BACnet is fix defined. The configuration of the device is 
accomplished with DIP switches and with Standard BACnet clients. 

BACnet Standard Device Profile:

  

BACnet Application Specific Controller (B-ASC) 

BACnet Interoperability Building Blocks supported:  

Data Sharing - ReadProperty-B (DS-RP-B) 
Data Sharing - ReadPropertyMultiple-B (DS-RPM-B) 
Data Sharing - WriteProperty-B (DS-WP-B) 
Data Sharing - WritePropertyMultiple-B (DS-WPM-B) 
Data Sharing - COV-Unsolicited-B (DS-COVU-B) 
Device Management - DynamicDeviceBinding-B (DM-DDB-B) 
Device Management - DynamicObjectBinding-B (DM-DOB-B) 
Device Management - DeviceCommunicationControl-B (DM-DCC-B) 

Segmentation Capability:  

No

 

Data Link Layer Options:  

MS/TP master,  

   

 

 

baud rates: 9'600, 19'200, 38'400, 76'800 

Device Address Binding:  

No static device binding supported

 

Networking Options:  

None

 

Character Sets Supported:  

ANSI X3.4 / UTF-8 

Standard objects (general) 

These BACnet objects exist only once per device: 

Datapoint 

BACnet Object 

-- Device 

Device   [x] 

-- Device ID Offset 

AV  

[1] 

-- COV Mode 

MV  

[1] 

  The Device Object Identifier (Device-ID) is defined by the BACnet MAC address (TS) and 

the Device ID Offset: Device-ID=TS+Offset. 

  The Device Object Name is defined by the Product Name and the Device-ID:  

e.g. "UK24BAC_1001" 
The calculated value can be overwritten using WriteProperty services. Reset to 
automatically calculation by writing an empty object name (empty or space character only).
