Modular Building Controller (MBC); Remote Building Controller (RBC)

Primary Control Unit
Modular (MBC) and Remote (RBC) Building Controller
Last Saved: Jul 20, 2006 10:22:42 AM

Description

Product Name(s):

  • Modular Building Controller (MBC)
  • Remote Building Controller (RBC)

Product Description:

The MBC and RBC are modular, programmable primary controllers with supervisory interface capability to monitor a secondary controller network. The MBCs are available in 48 I/O (24 module ports) or 80 I/O (40 module ports) capacity enclosures. RBCs have a 24 I/O (12 module ports) capacity enclosure. The enclosure assembly includes: enclosure; backplane; mounting rails for the Open Processor, Power Module, and Point Termination Modules; a duplex receptacle; and a step-down isolation transformer.

Product Application(s):

The MBC and RBC are designed to control general HVAC applications including air-handling units, chillers/boiler/central plant control and distribution systems, data acquisition, and other multi-equipment applications. The RBC is a smaller capacity version of the MBC with more communications and security options to allow for remote communications. Both the MBC and RBC provide on-board control of I/O points and central monitoring for distributed secondary control units and other building systems (e.g. fire/life safety, security, and lighting).

Additional Information  
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Trend Data Storage
Can trend data be stored in this controller? Yes
How many total trend values can be stored? Trend storage is limited to available RAM.
What is the controllers role in trending? Programming resident within SI gathers and stores trend data on-board. At set intervals, data is sent by the SI to workstation or called by the workstation for archival.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?  
When full, does controller automatically send up trend data; overwrite data, or stop logging data? Old data is overwritten if controller trend data memory fills before being called by archive workstation.
Programming

Programming Method(s)

(See Also 'Software' Form)

 Primary controllers are programmable from an operator workstation or portable operators terminal using proprietary line-based programming package (Powers Process Control Language; or PPCL).
Resident vs. Non-Resident Program Execution All programming is resident and executed at the controller.

Scheduling

(See Also 'Software' Form)
yes Resident/Supervisory. This controller supervises the scheduling of other controllers.
yes Resident/Stand Alone. This controller contains its own schedule.
no Non-Resident. This controller is dependent upon another controller for its schedule.
no None. This controller has no scheduling features.
no Other

Resident Energy Management

(Controller-resident energy management functions/algorithms calculated and performed by this controller. These typically require point-sharing and can involve calculations and multiple-loop functions. One or more of these choices may be selected.)
yes Energy management algorithms for this controller can be custom programmed
yes Pre-programmed/built-in algorithms available, and are fully editable using custom programming
no Pre-Programmed/built-in with limited editing via template-based programming
no Controller is not typically used for energy management functions
no Others
