PowerNetGeneral Description

The Cutler-Hammer PowerNet sys-tem is designed to manage the power distribution system. This integrated power management system is the ideal tool to help manage energy costs, troubleshoot power quality problems, and ensure the reliability and integrity of the electrical distribu-tion system. It is well suited for appli-cation in a manufacturing facility, a process-oriented plant, a commercial office building, a utility generating plant and a multi-building campus.

The Cutler-Hammer PowerNet system consists of PowerNet software net-worked with Cutler-Hammer prod-ucts of unparalleled breadth, accuracy and reliability: meters, relays, trip units, motor protectors, starters and transfer switch controllers, thus form-ing the most comprehensive power management system solution in the industry. In addition, the extensive library of third-party interfaces makes Cutler-Hammer PowerNet uniquely qualified to be the single solution for an existing or new application.

Energy Management

A Cutler-Hammer Power-Net system is the keystone of a successful energy management program. It

can provide data to verify the energy bill for the site, allocate the cost to individual users, identify potential energy saving opportunities through submetering and load profiling, and provide the information necessary to construct and implement an energy strategy in the deregulated environ-ment. Cutler-Hammer PowerNet data can be delivered to desktop PCs throughout the facility, enabling energy users to be active participants in managing energy costs. With Cutler-Hammer PowerNet, facilities have lowered energy costs by

reducing consumption, identifying and modifying usage patterns, nego-tiating more attractive utility rate structures, and allocating costs to departments or processes.

Power Quality

A Cutler-Hammer PowerNet system helps to ensure optimal electrical power quality, an increasingly

important consideration with the con-tinued growth of nonlinear loads and increasingly sensitive production and office equipment. Poor power quality can result in expensive downtime and costly equipment failures. The Cutler-Hammer PowerNet system provides real-time data and alarms as well as historical profiles to isolate the source, magnitude, time and direction of power quality problems, including voltage disturbances, harmonics and power factor.

Reliability and Uptime

A Cutler-Hammer Power-Net system provides crucial electrical distribution sys-tem information to ensure

power system uptime. It provides alarms warning of protective trips, potential equipment maintenance requirements, detailed trip diagnostic data, and other troubleshooting data essential to reliable operation. Use of this data can eliminate unnecessary trips and isolate a fault to ensure min-imum downtime, thus minimizing lost revenue and profits. The remote con-figuration and data-gathering feature of Cutler-Hammer PowerNet reduces labor costs, recording errors and potential miscoordination.

Information and Systems Integration

A Cutler-Hammer PowerNet system ensures that the right information is avail-able to anyone on- or off-

site to make an informed decision. It combines the above mentioned

as — energy usage correlated with parts produced providing cost per piece — or — quality of power corre-lated with part rejects producing potential quality linkages — provides the facility, production and front office staff more information to make better decisions.

Architecture

Flexibility is a key feature of the Cutler-Hammer PowerNet open design network. Multiple users and vendors may use the same Cutler-Hammer PowerNet network, elimi-nating the need for a proprietary net-work dedicated to a single vendor. Your existing plant Ethernet network can be used as the backbone for your Cutler-Hammer PowerNet monitoring system, avoiding the cost of installing dedicated network wiring or hardware.

In addition, power management data can be shared across the facility or across the world. The high-speed Ether-net architecture of Cutler-Hammer PowerNet is the same architecture that moves gigabits of data to millions of Internet and e-mail users.

energy management, power quality and system uptime information with the software tools to turn that data into information that can help you manage your business more effec-tively. The information can be made available at the plant site, at head-quarters or at a key consultant or service provider — anywhere it is needed and the expertise to use it is available. The system “brings the problem to the expert, instead of requiring the expert to go to the problem” — significantly improving productivity. All this using standard, open, Windows-based software, uti-lizing open Ethernet TCP/IP architec-ture, substantially reducing the cost of implementing the Cutler-Hammer PowerNet system.

Cutler-Hammer PowerNet and

DeviceNet

The Cutler-Hammer PowerNet system can also be seamlessly integrated with the Cutler-Hammer DeviceNet system into a single, common, site automation system. This combina-tion of the “facility” (Cutler-Hammer PowerNet) and the “factory floor” (DeviceNet) provides real-time and historical information to help manage your business. Information such

IMPACC Compatibility

Cutler-Hammer PowerNet is back-ward compatible with existing IMPACC systems on a dedicated network or twisted pair network.

Engineering Services

Supplementing the hardware and software, Cutler-Hammer Engineer-ing Services can provide local start-up and integration services to cus-tomize the Cutler-Hammer PowerNet system to your specific business needs. Basic field start-up, integra-tion of Cutler-Hammer PowerNet into other plant systems, and remote monitoring of the plant with industry experts in energy and power quality are all services provided by our local field representatives. These services will ensure that you get maximum return on all of your system investments.

Cutler-Hammer PowerNet Software

Cutler-Hammer PowerNet systems do not consist of exclusively Cutler-Hammer products. Hundreds of drivers exist to communicate with many vendor’s meters, protective relays and PLCs.

Flexible Network Architecture

A Cutler-Hammer PowerNet network can be built in a variety of configura-tions. Systems can be built using existing Ethernet networks as the backbone as well as on a dedicated twisted shielded pair running throughout a facility. Telephone, radio and fiber modems can be used to create networks where it is cost prohibitive to run dedicated cables. The most flexible, highest perfor-mance network architecture includes a dedicated twisted shield pair net-work within the switchboard or equipment room connecting into a high speed Ethernet backbone. For a layout of a typical facility network, please refer to the Cutler-Hammer PowerNet network overview on

pages 66-67.

Ethernet Backbone

TCP/IP Ethernet networks have become the worldwide standard for moving information. Industry has recognized Ethernet as a high speed, flexible, low-cost network that is not vendor dependent. Multiple vendors and users can share Ethernet back-bone networks. The Cutler-Hammers PowerNet network utilizes a standard TCP/IP Ethernet as the high speed backbone for carrying information to clients across the plant or across the world. The two products designed for interfacing directly to a TCP/IP Ether-net network are the Ethernet PONI, designed for a single device, and a NetLink, designed to connect multiple devices to an Ethernet backbone. Ethernet networks can utilize a com-bination of cable, including unshielded twisted pair, coax and fiber.

Dedicated Twisted Shielded Pair

Customers who desire to run a dedi-cated network for the power monitor-ing network have a choice between a dedicated Ethernet network or run-ning a twisted shielded pair. A net-work of 1000 devices running up to 10,000 feet can be networked through one twisted shielded pair of wire. For networks involving more than 1000 devices, a second twisted shielded pair can be added allowing 2000 devices to be monitored by a single computer.

Existing Network Media

When creating a network in an exist-ing facility, it may not be economical to run a dedicated twisted shielded pair and Ethernet may not be avail-able. In this case, line drivers are used to route communications across existing networks other than Ethernet. Line drivers allow the use of telephone lines, fiber and radio transmitters for wireless communications.

Cutler-Hammer

The NetPower Monitor client is a sim-ple-to-use, spreadsheet-like interface for real-time monitoring of the electri-cal distribution system. NetPower Monitor allows the user to customize the output in an interactive table for-mat.

Other features of NetPower Monitor are:

■

Drag and drop configuration

■

ActiveX Monitor and Control screens for all configured Cutler-Hammer PowerNet devices

■

Customizable device groups.

■

Device alarm monitoring

NetPower Graphics

NetPower Graphics is the powerful graphical user interface for integrating multiple vendors’ equipment within one software package for display of custom one-lines, elevation views and site plans. NetPower Graphics can provide the user with color-coded one-line symbols which indicate the device status, including open, close alarm and trip. It also has the ability to indicate the bus energization state and can be customized to locate alarms within user one-lines where an event has occurred.

NetPower Graphics was developed based on the Wonderware InTouch

�

software packaged with the Cutler-Hammer Net DDE Server and ActiveX components for use as an integral component in the Cutler-Hammer PowerNet system, fully compliant with the Cutler-Hammer PowerNet security and communication network.

NetPower DDE Pager

The DDE Pager automatically alerts essential personnel that a parameter monitored through PowerNet has

registered outside the predefined limits. The conditions warranting an alarm page are set by the PowerNet administrator and can be based on any monitored parameter.

The administrator may require that an alarm page be sent immediately after a condition is registered, such as a circuit breaker timing out to trip, or may require that the alarm condi-tion be present for a predefined period of time before creating an alarm page. Conditions such as an undervoltage present for less than five seconds may not be considered an alarming event, but if the condi-tion persists, a page may be sent. Additionally, a follow-up alarm page may be sent in response to any alarm condition not corrected.

The alarms are picked up through a DDE server, allowing the integration of multiple vendors’ equipment as well as existing Series

III

systems. Both numeric and alphanumeric pag-ers are supported.

NetPower Waveform

The Cutler-Hammer PowerNet suite also features the Waveform software which provides a snapshot of metering and power quality data at the time of wave captures.

The user can view and upload cap-tured waveforms from the following Cutler-Hammer devices shown in the table below. NetPower Waveform can then be used to upload the waveform from the device for analyzing.

Cutler-Hammer PowerNet Software Suite

The Cutler-Hammer PowerNet Software Suite includes multiple client and server programs. Cutler-Hammer PowerNet software is sold in packages or can be purchased as individual components. Regardless of the components a user chooses to purchase, the customer will receive a compact disk including all client and server applications. These client applications can be loaded on any personal computer. A customer actu-ally purchases the licenses to run the software. These licenses are con-trolled at the server and grant users anywhere on the network with the correct security privileges the right to run the software. Client licenses will run on a Windows 95, 98 and NT4.0 workstation or server. A DeviceS-erver communicating to a CONI card must run on Windows NT.

NetPower Bill

NetPower Bill is a billing software package that allocates energy con-sumption costs to individual tenants, departments, processes or products.

This software produces reports, or Energy Bills, of individual energy usage which can be printed, saved to file or distributed via e-mail.

Energy is allocated based on kWh and peak kW demand coincident to the utility peak demand. kVAh on kVA demand billing will also be available early 1999.

NetPower Trend displays historical load-profiles for the entire power dis-tribution system. When used in con-junction with the NetPower Bill software, NetPower Trend presents load-profiles for individual meters or energy users.

NetPower Trend can be configured to automatically plot curves at defined intervals — daily, weekly or monthly. The flexibility of NetPower Trend allows a user to view an entire cate-gory of load or user data without manually selecting each member of that group; for example, a user may choose to view all chiller data, all department meters, all utility meters or all energy users.

Energy Trending of Multiple Meters

NetPower Bill also serves as a mech-anism to evaluate alternate utility rate structures. Based on monthly billing data and various user-defined utility rate structures, NetPower Bill will provide reports which can be compared for cost effectiveness.

NetPower Bill must be used in con-junction with the NetPower Core. NetPower Track, an add-on option to NetPower Bill, when used by indus-trial users as part of an MRP system, provides manufactured cost-per-piece information.

NetPower DDE Energy Logging is an optional component that allows NetPower Bill to work with any non-Cutler-Hammer meters with a standard DDE Server or a DDE Server from the meter manufacturer.

NetPower Trend

NetPower Trend also displays the time and value of a particular trend point when the user merely places the cursor near a trend point, thus eliminating the need for the user to approximate where the curve would intersect the axis.

NetPower DDE Server

The DDE Server provides real-time, power monitoring data in Microsoft Standard DDE format. HMI Programs, such as Cutler-Hammer’s NetPower Graphics, Wonderware InTouch, and others offer DDE interfaces into their software. The NetPower DDE server eliminates the use of NetDDE for transporting information across a network. User security and access control commands are controlled through PowerNet Security. DDE values provide validity bits ensuring data is valid and the network con-nection is intact. One DDE Server is required for each machine running a DDE client.

NetPower Modbus Tools

Modbus Tools allow a device server to be configured to output Modbus RTU information to an RS-232 port at speeds up to 19.2K baud. Register mapping places information from IMPACC meters and protective relays into Modbus RTU registers. The bridge also supports control features to allow a Modbus master to send control commands to the IMPACC devices.

NetPower CoreNetPower Core consists of NetPower Configurator, DeviceServer, NetPower License Manager, NetPower Security Manager and NetPower Tools, all of which are described below.

NetPower Configurator➀

The NetPower Configurator is the Cutler-Hammer PowerNet client package that allows configuration of PowerNet devices through a Device-Server. Systems can be configured while communicating or off-line for downloading at a later time.

Cutler-Hammer

The Configurator allows the user to define the device parameters to be polled and the polling rates for each parameter producing optimal, cus-tomized results. Three polling rates can be set to a one-second resolu-tion. Device status can be polled at a higher polling rate than analog data to ensure quick notification of critical status changes such as trips.

NetPower Setpoints & Trip Curve

The NetPower Setpoints & Trip Curve client provides access to meter and protective relay settings, and if these devices allow remote configuration, the software enables these devices to be configured on-line. For devices not equipped for remote configuration, the device set-tings are displayed, but editing is disallowed. Meter and protective relay settings can be saved and downloaded to other devices with similar settings.

The trip curve display feature allows for the display of an unlimited num-ber of protective relay coordination curves to verify the system is prop-erly coordinated.

Other features of Trip Curve Display include:

■ A log-log coordination curve plot-ted on screen for trip units and motor protective relays with the click of a button.

■ Online modification of trip curve pickups and time delays; instant verification of coordination with an updated trip curve.

■ Automatic scale adjustment based on device pickup level.

■ Addition or Removal of trip curves directly from the display screen.

■ Color-coded curves tied to the device description for added clarity.

DeviceServerThe DeviceServer is a software or firmware program that can commu-nicate to a maximum of 2000 devices per DeviceServer. The DeviceServer enables communications on a TCP/IP network, providing Cutler-Hammer PowerNet clients with real-time power data, device event information, device waveforms, energy logging, and historical profile data.

The DeviceServer takes advantage of the message cueing capabilities of the CONI 3 card, buffering incom-ing and outgoing messages, thus reducing operating system delays by servicing multiple data messages per system request. A DeviceServer may be purchased to support Modbus RTU through a serial port in place of or in conjunction with its Ethernet network.

Device LicensingDevice licenses are available in packages of 20, 100, 200 or 1000. A device license must be applied to an individual DeviceServer running on a personal computer running Microsoft Windows NT or 95/98. NetLinks are included with an imbedded DeviceServer capable of communicating to 200 devices.

NetPower License ManagerNetPower License Manager is the server component of the Cutler-Hammer PowerNet suite that man-ages the number of client licenses that have been purchased by the customer. Each license is a “floating” license which, upon being relinquished by one client, may be issued to another client by the server.

For example, suppose a customer purchased three Waveform client licenses. At any given time, three individuals may check out a license and run the software. When one of the individuals is finished running the software, the license may be returned to the server, allowing another individual to check out the unused license and begin running the Waveform client. Returning a license is as simple as clicking on “Exit” rather than “Exit and Keep License.”

NetPower Security ManagerThe user with administrator privi-leges can create users on the Cutler-Hammer PowerNet system, each with specific privileges. Cutler-Hammer PowerNet Security system then monitors users’ requests to access functions and either grants or denies access based on those pre-defined privileges. Devices also can be grouped into different classes and a user can be granted or denied control of a specific device class.

NetPower ToolsThe NetPower Tools component of Cutler-Hammer PowerNet manages the process of collecting power dis-tribution data from Device Server and merging it to central ODBC data-bases. No user intervention is required. At predefined time intervals — hourly, daily or weekly — data is merged into the central database. The ODBC database then provides the composite information to client applications such as NetPower Trend to display load profiles and NetPower Bill to calculate energy bills.

The advantage of distributing data storage is that the backbone network need not be available for data collec-tion, and no data is lost when the network is temporarily shut down.

NetPower Tools can also be used to archive and restore historical data.
