MatrixBBC : BACnet Building Controller

BACnet Building Controller

A high-performance, fully programmable, Native BACnet Building Controller (B-BC), the MatrixBBC is designed to provide dependable global and area control functions to a connected BACnet building automation system. As a BTL-listed device, the MatrixBBC is ideal for various applications ranging from traditional area control, large mechanical rooms, and central plant applications, to other applications that require support for bulk I/O.

Combining both software and hardware flexibility into one package, the MatrixBBC provides support for expansion I/O and high-speed BACnet network data routing. It also allows for centralized control of devices, schedules, calendars, and alarms, along with other features and items. Scalable program routines can be accomplished using line-by-line programming or creatable logic-blocks based on second-generation NB-GPC product technology.


  • The MatrixBBC provides technicians with the ability to dynamically create and delete objects as they are needed. Common objects supported include:
  • Bulk I/O Support (MATRIX-BBC-DP-SSB)
    Up to 13 STATbus IOX Modules can be connected. This allows a possible maximum count of 144 Universal Inputs, 72 Analog Outputs, and 72 Digital Outputs.
  • Full BACnet Data Routing
    Routes information between BACnet MS/TP, BACnet/IP, and BACnet/Ethernet (8802-3) networks.

    Supports localized, as well as Internet-based BBMD applications that involve Network Address Translation (NAT) equipment.

    Acts as a foreign-device registrar, supporting temporary access for engineering tools and other devices across network connections.

  • Schedules (32 Max)
    Schedules support the ability to adjust values within the MatrixBBC, as well as values on remote devices connected to the BACnet network. Provides full support for flexible weekly scheduling and exception scheduling.
  • Data Storage Objects (1000 each, max.)
    Analog Value and Binary Value objects are supported. Both provide support for alarming and command prioritization.
  • Calendars (32 max)
    Supports the ability to define a list of dates, date ranges, and special events for use with Schedules and other programmatic routines
  • SPL Program Support (64 program regions max)
    Each region supports up to 8kb of compiled program statements with accessibility to all internal objects, as well as data on remote devices connected on the BACnet network.
  • GPC Logic Blocks
    Common blocks such as Control Loops (PID, Thermostatic, Pulse Pair), Data Movement (Remaps, Netmaps, Broadcasts), and Data Manipulation (Math, Logic, Scale, Input Select, Staging, etc..) can be created and used when necessary.
  • Trend Logs (256 max) 
    Contains BACnet compliant Trend Log objects which sample a single data point within the MatrixBBC or a connected network-device. Supports collection in polled duration or change of value (COV).
