Interfacing UPS Systems to a BACnet Network

Interfacing UPS Systems to a BACnet Network

Monitoring the UPS alarms from BACnet presents challenges that are not compatible with traditional gateways. BACnet stands for Building Automation and Control Networks. It is a communication protocol standard designed specifically to provide a way to integrate building control products made by different manufacturers.

To interface a UPS system with a BACnet network, you typically need a dedicated "BACnet gateway" or a network card within the UPS that can translate the UPS data (often communicated via SNMP) into BACnet objects, allowing the UPS status and parameters to be monitored and controlled by a Building Management System (BMS) on the BACnet network; essentially acting as a protocol converter between the UPS's native language and the BACnet protocol.

Data centers monitor all of their equipment using SNMP, which stands for Simple Network Management Protocol. This protocol is intended for managing networks and network equipment. Therefore, data centers will monitor everything from servers, routers, and switches to UPS systems and transfer switches using SNMP. 

The old way of doing things had the IT people monitoring the IT related equipment with their own network while the building management people had their own network to monitor HVAC and building related things (if they had any network at all). The line in the sand between these two monitoring networks is rapidly washing away. Building management wants more information from the IT side, especially when it comes to backup power systems. Network management wants to know more from the building side, especially when it relates to HVAC and keeping network equipment running cool.

What is a UPS?

A UPS is a battery-powered device you can plug into your building's electrical system to provide a backup source of power. It does this by continuously monitoring the available electricity and routing it around any problems, such as brownouts or blackouts.

Key points about interfacing UPS systems with BACnet: -

·        Gateway Device:

A dedicated gateway is usually required to bridge the communication between the UPS (often using SNMP) and the BACnet network, mapping SNMP variables to appropriate BACnet objects. 

·        Data Translation:

The gateway translates UPS data like voltage, current, battery status, alarms, etc., into standardized BACnet objects that can be readily understood by the BMS. 

·        Network Card Option:

Some UPS models may offer built-in BACnet network cards that directly enable communication on the BACnet network without an external gateway. 

·        Monitoring and Control:

Once integrated, a BMS can monitor various UPS parameters like power status, battery level, alarms, and even initiate actions like graceful shutdown in case of power failure.

·        Controller with BACnet support:

The Distech controller you use needs to be equipped with a BACnet module or functionality to communicate with other BACnet devices on the network. 

·        Wiring connection:

Connect the UPS to the controller using the appropriate wiring based on the UPS model and controller input specifications. 

·        Configuration within controller:

Access the controller's programming interface and navigate to the BACnet settings to add the UPS as a device, defining its parameters like voltage, current, battery status, etc. 

·        Data points and object types:

Within the BACnet network, the UPS will be represented by specific data points (like "battery level", "power factor") which can be accessed by the BMS system for monitoring and control. 

Benefits of integrating UPS with BACnet:

·        Centralized Monitoring: Access all UPS information within the BMS alongside other building systems like HVAC, lighting, and security. 

·        Automated Response: Trigger alarms and take corrective actions based on UPS status changes. 

·        Improved Efficiency: Monitor power consumption and identify potential power issues proactively. 

Considerations when integrating UPS with BACnet:

·        UPS Compatibility:

Check if your UPS model supports BACnet communication, either natively or through a compatible network card. 

·        Gateway Selection:

Choose a gateway that supports the specific UPS communication protocol (like SNMP) and can accurately map data to BACnet objects. 

·        Object Mapping:

Properly configure the mapping between UPS data points and BACnet objects to ensure accurate data interpretation by the BMS

How to access the UPS data on BACnet:

·        Access the controller interface: Use the Distech controller's web interface or dedicated software to access the BACnet network.

·        Browse devices: Navigate to the BACnet device list to view the connected UPS.

·        View data points: Select the UPS device to access its individual data points, allowing you to monitor parameters like battery level, power consumption, and fault status. 

How it works:

1. Data collection:

The UPS collects information about its operational status, including battery level, input voltage, and alarm conditions.

2. BACnet translation:

The UPS gateway or module converts this data into BACnet objects, which are standardized data structures recognized by the BMS.

3. Network communication:

The BACnet objects are transmitted over the network to the BMS server using the BACnet protocol.

4. Data presentation:

The BMS software displays the UPS data on the user interface, allowing monitoring and control actions based on the received information.

BACNET interface allows UPS models of the MASTERYS, MODULYS GP 2.0 and DELPHYS families to be connected to a BACNET network for BMS management.

NetMan 208 is a network communications card that enables Riello UPS systems to easily integrate into medium or large networks, providing a high level of reliability in communication between the UPS and associated management systems. 

The Babel Buster 3 creates a BACnet interface for UPS systems by converting SNMP to BACnet. The Babel Buster 3 acts as a protocol translator, converting variables found in the SNMP MIB to BACnet objects. You may then use BACnet to monitor the UPS from your Building Management System.

To connect a Distech BMS UPS to a BACnet network, you would need to use a Distech controller with BACnet capabilities, connect the UPS to the controller via the appropriate wiring, and then configure the controller to recognize and communicate with the UPS using BACnet protocol, allowing you to monitor and control the UPS status within your building automation system.

APC single phase UPS (SMT, SMX, SMTL, SRTL, SURT, SURTD) units global offer with APC Network Management Cards which is BACnet capable.
