Building Energy Management System (BEMS) BEMS Overview

1. BEMS OverviewThe Building Energy Management System is an analysis tool producing charts and

reports to evaluate energy usage in buildings, campuses and other facilities.

This Building Energy Management System (BEMS) Software runs in association withWebAccess HMI & SCADA software. This is a software product requiring users to

install appropriate energy monitoring hardware (such as electric kilowatt-hour

meters, gas flow meters , etc) that can be connected to IO or automation hardware.These sensors are then read by the WebAccess HMI & SCADA software which in turn

makes this data available to the BEMS software.

The BEMS software creates a set of ODBC databases (MS Access is the default)independent of the WebAccess HMI & SCADA databases.

The BEMS software creates a set of pre-formatted charts and reports commonly usedin Energy Analysis of Buildings and Facilities. These preformatted displays are best

viewed at 1280 x 1024 pixels resolution or greater.

1.1 BEMS Analysis Displays and Reports

There are ten (10) preformatted analysis displays, many with multiple options andmost with a report version , yielding several dozen possible analyses and reports.

The ten basic displays are:

Energy Profile - shows energy usage usually compared to a reference value.Energy Ranking - compares energy measurements in ascending or descending

order.

Energy Comparison - energy use versus different time periods or different sources.Average Daily Profile - energy use over a given day for one or more sources.

Differential Analysis - calculates the difference of actual energy use versus atarget value.

Max / Min Analysis - calculates the top Maxima or Minima for a Group of energysources over the selected time period.

Primary Energy Profile - displays energy use in equivalent use of Coal, Oil, CO2 orHeat.

Cost Profile - displays the cost of energy for selected sources and time periods.Cost Ranking displays energy costs in ascending or descending order for theselected period .

Statistics Report - displays summary of energy use and costs for selected period.

Figure 1.13 Statistics Report Energy Use and Costs, Jan 24 to 28 for

entire project named BEMS1.

Rate calculations of Cost are not enabled in this version of BEMS. The Rate part ofthe report will be all zeroes.

BEMS Architecture

The BEMS uses a set of ODBC databases on the Project Node to collect real-

time data (the default is Microsoft Access). These databases are separate andindependent of the databases used for Analog Tag log, Scheduled reports and

Data Log Trends.

The SCADA node collects the data for the BEMS and sends it to the Project

Node via the WebAccess Network Service (webvrpcs.exe).

The Project Node also generates the BEMS Analysis displays.



18/111


Both the SCADA node (VIEW and ViewDAQ) and the Project Node (BEMS

Project Manager) can display the BEMS reports. Although VIEW and ViewDAQare calling up an ASP page generated by the Project Node.

The SCADA Node and the Project Node can be the same computer.

1.2.1

1.2.2

Project Node stores data and generates displays

The Project Node is a web server and database server. The BEMS datatablesare located at drive:\WebAccess\Node\bamdb on the Project Node.

The Project Node also generates the BEMS Analysis displays and reports. Noconnection to the SCADA node is needed to generate the BEMS displays and

reports. These BEMS displays are generated in ASP (Active Server Pages) onthe Project Node (Web Server) using VMC (Vector Markup Language).

Data is stored via ODBC to Access database files located on the Project node

at drive:\WebAccess\Node\BAMDB. The database files are typically named:BA_Data_0.mdb through BA_Data_4.mdbBA_Cfg.mdb

BA_Rate_1.mdbBA_Rate_2.mdb

The ODBC system DSNs are typically named:BA_Data_0_Access to BA_Data_4_Access

BA_RATE_1_AccessBA_RATE_2_Access

BACFG_Access

SCADA Nodes collect data

The SCADA node collects the data for the BEMS and sends it to the Project

Node via the WebAccess Network Service (webvrpcs.exe).

The SCADA node must be running to collect data. View data already collected

in the past, only the Project node is needed.

The SCADA Node communicates in real-time with automation equipment.

The SCADA node is physically connected to automation hardware via Serial,Ethernet or proprietary communications. Typical automation equipment

include Programmable Logic Controllers (PLCs), Single Loop Controllers,

Direct Digital Control Systems (DDC), Distributed Control Systems (DCS) andIO (input / Output) systems.

The SCADA Node is the computer directly connected to a plant control

system. The SCADA Node typically has a serial, Ethernet or proprietarynetwork card communicating directly with PLCs, Controllers and IO racks. The

SCADA Node also has a network connection to Clients. The SCADA Node

retransmits data between the controllers and clients. In a sense, the SCADAnode is a "SCADA Server".

1.2.2.1

1.2.3

KiloWatt-Hour meters

The BEMS measurement and analysis of electrical power is designed to beused with Kilowatt-Hour meters. The BEMS takes a difference in readings

every 5 to 15 minutes to calculate the Kilowatts used over that period.

It is important that the Kilowatt-hour meters do not turnover, resulting innegative energy use calculated for that period.

There is no provision in the BEMS to change the units or scaling.

However Calculation tags could rescale the watt-hour meter to Kilowatt-hour

and the Calculation block be used for input to the BEMS.

Similarly, Accumulation tags could be used to calculate Kilowatt-Hours fromwatts or kilowatts.

The drawback to using Accumulation Tags or other software methods tocalculate Kilowatt hours is if the PC stops or is restarted. If the calculated

kilowatts are set to zero, then large negative values for Kilowatt-hour may becalculated for the next 5 or 15 minute period.

Each SCADA node communicates to kilowatt-hour meters either directly orindirectly through automation equipment (PLCs, DCS, IO, etc) using the

communication drivers supplied with WebAccess.

WebAccess Configuration Manager

The WebAccess Configuration Manager is used to create Projects, Items (i.e.

energy meters) and Groups of energy meters. The ability to configure a BEMSproject is available even if the option was not purchased as part of the SCADA

node license.



20/111


Figure 1.3.3 BEMS Project Manager development tool

The BEMS Project Manager is the development tool to create a BEMSproject by linking measurements of energy usage to items and groups.

An Item is a single energy source, often with multiple measurements from

the same meter, for example Kilowatt-Hours, Reactive Power (KVARs),maximum demand, costs etc.

A Group is a related set of measurements, for a example a Building withmultiple measurements or a campus with multiple buildings. A Group usually

consists of Items, although Groups can consist of other Groups and a mix ofItems and Groups.

Additional System Requirements

Project Node Additional System Requirements

The project node will be storing the collected data in ODBC database files.These are in addition to the other ODBC data files (analog tag log, digital taglog, et al). These BEMS files record to the Hard Drive of the Project Node.

BEMS data recording to ODBC database

The BEMS package records a data value every 15 minutes for each Item andits associated measurements (for electric power a single Item has potentially

5 measurements: KWH, KVARH, Max Demand, Kilowatts and Load Factor).

These apply to the Project Node (for BEMS ODBC database files).

BEMS Disk Space

Each ODBC record requires about 34 bytes on the hard drive of the Project

Node (a group of Access Database by default, in a subdirectory atdrive:\WebAcces\node\bamdb).

20 tags * 34 bytes/sample * 4 samples/hour * 24 hours/day * 30days/month = 2 Megabytes in a month.

20 tags * 34 bytes/sample * 4 samples/hour * 24 hours/day * 365

days/year = 23 Megabytes in a year.

The Maximum file size of an Access Database is 2 gigabytes.

Note - The Log Data Maintenance feature in WebAccess currently does

not support archiving or deleting of BEMS data..

SCADA Nodes minimal additional Requirements

There are additional communications required between the SCADA node and

the Project Node. But these do not appear to be large, approximately 34

bytes per record every 15 minutes.

Client Additional System Requirements

Display Resolution: The BEMS Analysis Displays are best viewed at 1280 x1024 pixels resolution or greater.

1.4.3

1.4.4

Development License (Project Node)

Users can begin configuration of a BEMS project without a license inWebAccess Configuration, which runs on the Project Node.

There is no charge for a Project Node License. Users may install multiple

Project Nodes at no additional charge if they own a valid SCADA node licenseand follow the License Agreement. The Project Node is the configuration

tool. It may be copied to laptops and other PCs to allow off-line development,graphics building, testing and training. There is no Hardkey required for a

Project Node.

There is no WebAccess licensing limit to the number of Clients that may

connect to a Project Node. However, since the Project Node uses IIS(Internet Information Server) or Peer Web Services as a Server for

WebAccess configuration, Microsoft Licensing will limit the number of clients.

The limit is 10 simultaneous connections in Windows 2000 and XPProfessional. In Windows 2000 and XP Server versions, the limit is dependant

on your license (it can be un-limited).

Please see the LICENSE AGREEMENT for more information

SCADA node License

The BEMS (Building Energy Management System) is sold as an option to aWebAccess HMI & SCADA software package. It uses the same Hardkey as

WebAccess HMI & SCADA software, but requires an addition to the LicenseControl file.

The SCADA node is the only node in the system with a Hardkey. EachSCADA node must have its own Hardkey and matching software license

control file. In the standard full-feature version, an unlimited number ofclients can connect to a SCADA node. However, the number of Clients might

be limited by the License purchased for the SCADA node.



30/111


1.4.5

1.4.5.1

HARD KEY

The BEMS uses the same Hardkey as the WebAccess HMI & SCADA software

(i.e. there is only one Hardkey per SCADA node). The hard key is a Sentinel

SuperPro manufactured by Rainbow Technologies. The hard keys connect tothe SCADA Node computers parallel or USB port.

The Hardkey serial number must match the serial number in the software

license control file. The software license control file describes how manytags are in the license. You will need the Software License Control file during

Installation of the SCADA node. The 'Control File" is usually distributed on aFloppy Diskette with your package. The "Control File" must match your

Hardkey.

If you have multiple SCADA nodes, you have to install a different 'Control

File" on each SCADA node and the "Control File" serial number must matchyour Hardkey's serial number.

If you do not have a Software License Control File, the "Demo License" will beinstalled. The Demo License is limited to 150 tags and runs for 2 hours.

If user moves his Hardkey to another computer and does not move his license

file, then the new computer will be forced into simulation.

If the user wants to upgrade his WebAccess BEMS, he would purchase a new

license file that he could copy to his computer, that matches his hardware keyand he could then use BEMS. Upgrades to BEMS can be accomplished via

email by updating only the License Control File. The serial number of Hardkey

and the license file must match.

Parallel Hard Key

The Parallel port version of the hard key is installed on a 25-pin parallel port

(D25) on the SCADA node that adheres to IBM standards: LPT1 is supported.

Electricity

The Electricity resource type requires the Active Energy field be filled. Theadditional fields are optional and used in some Rate Calculation to track cost

of electric power. The Rate Calculation is also optional.



67/111


Figure 3.10 Electricty Item. Only Active Energy is required.

3.4.2.1 Active Energy

In BEMS, Active Energy is designed to be from an electric power meter in

units of kWH (kilowatt-hours). The difference between the current readingand the previous reading is calculated and recorded to the database for this

time period (every 15 minutes is the default time period). It maybe be

necessary to use and Accumulation Tag in WebAccess if you are measuringKilowatts, then use the Accumulation Tag as the input to BEMS.

The Active Energy Field must have a tag name (it is required) for the

Electricity Resource type.

Reactive Energy

Rate calculations of Cost are not enabled in this version of BEMS. Since this

Reactive Energy field is only used in Rate calculation of Costs, it is not

currently useful.

Reactive Energy (kVArH ) is a reactive power, Q, over time = Q * h. Somerates are based on Reactive Power charges. And use wither kVArH, others on

just KVAr.

In BEMS, Reactive Energy is designed to be from an electric power meter in

units of kWH (kilowatt-hours). The difference between the current readingand the previous reading is calculated and recorded to the database for this

time period (every 15 minutes is the default time period). It maybe benecessary to use and Accumulation Tag in WebAccess if you are measuring

Kilowatts, then use the Accumulation Tag as the input to BEMS.

Reactive Energy is optional. It is needed only if your Electric Rate requires forcalculating the Cost of Power and you want to calculate Power Costs. It doesnot show directly on any BEMS display or report. It is shown indirectly only if

used in calculating costs.

Active Power

Rate calculations of Cost are not enabled in this version of BEMS. Since this

Active Power field is only used in Rate calculation of Costs, it is not currentlyuseful.

Active Power is the current kW (Kilowatts). This is current Rate from the

meter used to measure Active Energy. The current value is read every 15minutes and entered in the BEMS database.

Active Power is optional. It is needed only if your Electric Rate requires for

calculating the Cost of Power and you want to calculate Power Costs. It doesnot show directly on any BEMS display or report. It is shown indirectly only if

used in calculating costs.

Load Factor

Load Factor is Energy Used versus maximum allowed by rate contract duringa period.

Load Factor = kWH / (Max allowed Demand * h)

Load Factor Power is optional.

Load Factor is used as a Reference Value in the Energy Profile Display.

It is needed only if your Electric Rate requires for calculating the Cost ofPower and you want to calculate Power Costs. It does not show directly on

any BEMS display or report. It is shown indirectly only if used in calculating

Viewing & Using Energy

Analysis DisplaysThere are three methods to View the BEMS displays:

The BEMS Project Manager, which is inside the WebAccess Project Manager. This

uses only port 80 (or whatever you assigned as the http port). Only Admin andProject Users can view BEMS from the BEMS Project Manager.

VIEW. Currently only Power Users and Admin can view BEMS displays in View. The

default method is from the Right Click, Tools menu ( Right Click -> Tools -> BEMS).

View DAQ. All uses of ViewDAQ can view BEMS displays. The default method is from

the Tools menu on the upper menu bar.

BEMS Project Manager

The BEMS Project Manager is inside the WebAccess Project Manager.

This uses only port 80 (or whatever you assigned as the http port). The client plug-inis not needed, so this maybe an option for those unable to install the plug-in or

unable to connect via the Primary and Secondary TCP ports (default 4592 and14592) because of firewalls. However, only Admin and Project Users can view BEMS

from the BEMS Project Manager.

The toolbar and status bar in VIEW and ViewDAQ are also eliminated using this

method, allowing more area on the screen and being a little less cluttered if screencaptures are used.

Also, using the BEMS Project Manager, the BEMS displays can be viewed even if yhe

SCADA node is not running or is offline.

If you have not already done so, connect to the Project Node and Start WebAccess

Configuration.
