Overview
This chapter is an overview of Powermonitor Software system components
and capabilities. Detailed information regarding system requirements can be
found in Chapter 2.
Powermonitor Software is a software package designed to remotely display
the data measured by the Powermonitor. The Powermonitor Software is
capable of configuring and controlling all aspects of remote devices. In
addition, the Software can up load and store the Event and Snapshot Logs of
the devices onto disk files for database analysis or printout.
System Components
The Powermonitor Software system is comprised of a personal computer that
is connected via communication links to a Powermonitor through a Bulletin
1400–DCU communications card.
Computer Station
The Powermonitor Software requires an IBM Personal Computer AT, 286, or
386, or a true compatible with a monochrome or color monitor. The
computer must have a minimum 256K of RAM, an 80 column monochrome
or color monitor, and either a 5–1/4” (360KB or 1.2MB) or 3–1/2” (720KB
or 1.44MB) floppy disk drive. A hard disk drive is optional.
The computer set at a minimum should be equipped with one (RS–232C)
serial interface (port). With two serial (RS–232C) interface ports the
computer could be connected to a Powermonitor via one port and at the same
time be connected to another Powermonitor via the other port.
For remote connection, one port could have an internal modem or one of the
serial ports could be connected to an external modem. Modem connection
allows communication via the telephone network, radio links, fiber optic
links, and microwave data links.
The computer running the Powermonitor Software provides the system
operator interface to perform the following functions:
• Remote device programming.
• Data display from each device in the system.
• Communication of manual relay control commands to Powermonitors.
• Access to logs (Min./Max., etc.) setpoint control

h. engine/generator efficiency studies
Powermonitor Display Module
The Powermonitor provides electrical monitoring and control functions in a
wide variety of applications. The Powermonitor can be operated
independently in stand–alone applications, or used with a computer running
Powermonitor Software for local or remote device programming, setpoint
control, viewing of data, and manual relay operation. All functions of each
Powermonitor may be accessed from the Powermonitor Software computer
station. The Powermonitor Software also provides access to features that are
not accessible when the Powermonitor is used in strictly stand–alone
applications.
1–2
The Powermonitor performs high accuracy measurement of Volts (L–L,
L–N), Amps, kW, kVA, kVAR, kW Demand, Amps Demand, Power Factor,
Frequency, kWH, kVARH, kVAH, and Neutral Current. Dependent on the
range, connections can be made directly to potential transformers and current
transformers without the need for intermediate transducers.
An auxiliary voltage input can be used to measure parameters, such as,
transformer temperature or battery voltage. Four status inputs can be used to
monitor circuit breaker status, ground fault relay status, or any other voltage
input within the status input range.
The Powermonitor has an extensive user–programmable setpoint system.
Three on–board relay outputs can be used for fully automated demand,
power factor, or load control, or to trip a critical breaker or activate an alarm
in the event of under/over voltage, voltage or current unbalance, phase
reversal, etc. The three relays can be programmed for multiple setpoints.
On–board data logging capabilities provide Event/Alarm, Min/Max, and
Snapshot data which can be accessed and displayed through Powermonitor
Software.
Chapter 1
Overview
Communication Links
Many forms of communication can be used to transfer power data on a local
data bus to the computer running the Powermonitor Software. The local data
buses presently used by the Catalog Number 1400–DCU communications
card are either the electrical standards RS–232C or RS–485 and
Allen–Bradley Remote I/O link for PLCR (programmable logic controllers)
processors.
The RS–232C electrical standard is commonly used for point–to–point
communications and is excellent when only one
installed at a site.
For sites requiring more than one Powermonitor device, the RS–485
electrical standard is used. This standard utilizes a shielded two–wire twisted
pair cable as the communications media and can operate at distances up to
4000 feet.
Powermonitor is to be
System Features
ATTENTION: Special high level isolation is required between
units when the possibility of high ground potential differences
!
exist. This may occur when separate grounds are used, or when
communicating to a unit off of the power ground matt. Failure to
do so can lead to personal injury or death, property damage, or
economic loss.
The Powermonitor Software uses a non–proprietary packet protocol to
transfer information and data between the computer running the
Powermonitor Software and remote devices connected on the RS–485 bus.
The packet protocol features unit addressing and error checking capability.
Generally, a Catalog Number 1400–CC communications converter will be
needed to convert the computer RS–232C to RS–485 communications.
The Powermonitor Software does not support Allen–Bradley’s Remote I/O
network.
Control Features
The Powermonitor is equipped with on–board control relays. The relays may
be manually controlled by the system operator, or placed under automatic
control of the device itself in accordance with user defined parameters.
Only computer system operators with the appropriate password have access
to the relay control functions. The Powermonitor Software forced relay
requests require confirmation. This minimizes unintentional relay activity.
All forced relays return to normal operation if power to the unit is lost.

Overview
Data Acquisition Features
A Powermonitor has on–board Snapshot logging capability which allows
each device to store instantaneous measured values (ex. Volts, Amps, kW,
kVAR, etc.) at user–defined intervals ranging from 1 second to 400 days.
A computer running the Powermonitor Software can up load and display
Snapshot Logs, and save an entire log to a disk file for analysis at a later
date. The Powermonitor Software disk files are stored in format that is easily
converted to a LOTUS 1–2–3
TM
compatible format allowing users to apply
their own database application programs to generate any desired type of
report or graph. The use of this standard database file format also allows the
user to apply presently existing database application macros that have
already been developed.
Data Display Features
All real–time measured data, relay and status input conditions, and on–board
data logs can be accessed from a Powermonitor.
Operator Support
The Powermonitor Software provides an on–screen HELP utility which
provides information regarding communications, modem usage, and how to
obtain technical assistance should a user experience difficulties.

retained in some cases.
DOS versions 2.0 or greater can be used with the Powermonitor Software.
The computer running the Powermonitor Software utilizes one serial port to
communicate with the Powermonitors at each site in the system. Each
computer serial port can be connected to one or more Powermonitors via a
wide array of communications interface hardware options. Examples of
communications options supported by Powermonitor Software include direct
connection to single Powermonitors or telephone modem links via RS–232C,
and direct connection to multiple device sites via RS–485 local area
networks.
Number Of Serial Ports Required
The Powermonitor Software supports dual RS–232C or RS–485 serial ports
(COM1 and COM2). COM1 must be set to IRQ4 and COM2 to IRQ3.
The number of serial ports required by the computer varies from system to
system and will depend on the size of the system to be monitored.

Chapter 2
System Requirements
RS–232C vs RS–485 Communications
The Powermonitor Software can communicate to all Powermonitors in the
system either via the RS–232C electrical standard or via the RS–485
standard. The type of communication hardware required at each site is
dependant on which of these electrical standards is used by the
Powermonitors located at that site.
If there is only one Powermonitor installed at a site, then the optional port
can be set for either the RS–232C standard or the RS–485 standard. If more
than one Powermonitor is installed at a site, then the RS–485 electrical
standard must be used and all Powermonitors located at that site must have
their optional RS–232C/RS–485 port set for RS–485 communications.
ATTENTION: Special high level isolation is required between
units when the possibility of high ground potential differences
!
exist. This may occur when separate grounds are used, or when
communicating to a unit off of the power ground matt. Failure to
do so can lead to personal injury or death, property damage, or
economic loss.
To determine the setting of optional RS–232C/RS–485 port refer to
Publication 1400–5.0, ‘‘Catalog Number 1400–DCU Communications Card
Instructions Sheet.”
Connection To Remote Sites Via Telephone Lines and Modems
2–2
The Powermonitor Software supports Hayes compatible internal and external
modems at 300, 1200, 2400, 4800, 9600 and 19.2K baud. Before selecting a
particular baud rate, verify that all equipment used supports that particular
baud rate.
Installations using modems require individual RS–232C and telephone cables
at each modem location.
Configuration of external modems is described in Chapter 3, ‘‘Installation.”
Internal modems should be useable with their factory–configured settings. If
necessary, please contact Allen–Bradley.
Chapter 3, ‘‘Installation” contains detailed instructions regarding the
installation of telephone modem data links.

Installation
Connection To A Single
Powermonitor Via RS–232C
This section provides the information necessary to connect the computer to a
single Powermonitor via an RS–232C communications link.
To install an RS–232C communications link, both the computer running the
Powermonitor Software and the Powermonitor must be configured for
RS–232C communications.
ATTENTION: Before attempting to connect any
communications cables, confirm that each device is equipped
!
with a Catalog Number 1400 – DCU communication card, and
the port has been configured for RS–232C operation. For
jumper configuration, refer to Publication 1400–5.0
Instruction Sheet.
To implement an RS–232C communications link, a three conductor
RS–232C cable is required between the RS–232C serial port of the computer
and the serial port of the Powermonitor. If you wish to assemble the
RS–232C cable yourself, the cable pin assignments are given below.
Alternatively, pre–assembled RS–232C cables can be ordered from
Allen–Bradley.
To install the RS–232C cable, connect one end of the RS–232C cable to the
desired serial port at the back of the computer running Powermonitor
Software. The three conductors at the other end of the cable are then inserted
into the appropriate communications connection points located on the
Powermonitor. The three connection lines are as follows (refer to Figure 3.1
on Page 3–3.):

1. Computer DB–25P pin 2 (computer Tx ) connect to the RXD of the
communications card.
2. Computer DB–25P pin 3 (computer Rx ) connect to the TXD of the
communications card.
3. Computer DB–25P pin 7 (computer signal GND) connect to the SG of the
communications card.
Important: The RS–232C communications link described above allows
only one device to be connected to each computer serial port.

This section provides the information necessary to connect the computer
running Powermonitor Software to multiple Powermonitors via an RS–485
communications link.
An RS–485 communications link permits many Powermonitors to be
networked together on a two–wire twisted–pair local area network or LAN.
The computer can access information from any one of and up to 32 devices
connected to the RS–485 LAN.
To implement an RS–485 communications link, the computer running the
Powermonitor Software must be equipped with either an internal RS–485
communications card or an RS–232C serial port and an external RS–232C to
RS–485 converter. The Catalog Number 1400–CC converter can be used for
this purpose. Each Powermonitor to be connected to the RS–485 LAN must
be equipped with a Catalog Number 1400–DCU communications card
configured for RS–485. The communications cable required to connect the
computer to each of the Powermonitors consists of a shielded two conductor
twisted pair cable.
ATTENTION: Before connecting any communications cables,
confirm that every Powermonitor is equipped with a RS–485
!
communications port, and the port has been configured for
RS–485 operation. Refer to Publication 1400–800, ‘‘Bulletin
1400 Powermonitor Installation and Operation Manual,” for the
device to determine correct configuration of the port.

Chapter 3
Installation
ATTENTION: Never connect an RS–232C equipped
device to the DATA+ or DATA– lines of an RS–485
!
equipped communication system. Doing so will damage
the RS–485 driver circuits of every device within the site.
ATTENTION: Converters such as the Catalog Number
1400–CC converter must always be used between devices
!
that use RS232C/RS–485 communications standards.
If the computer running the Powermonitor Software uses an RS–232C serial
port in conjunction with an external Catalog Number 1400–CC RS–232C to
RS–485 converter, then install a straight 25–conductor RS–232C cable or a
cable configured with (3) wires to pins 2, 3, and 7 from the desired serial port
at the back of the computer to the RS–232C input on a Catalog Number
1400–CC converter. The DATA+ and DATA– lines on the RS–485 side of
the converter are then connected to the DATA+ and DATA– on each
Powermonitor via a shielded two–wire twisted pair cable as shown in
Figure 3.2.

Powermonitors.
Important: The multi–device remote site configuration outlined on page 3–8
should be used if more than one Powermonitor is to be installed at the remote
site in the future, or if a single device at a remote site is located more than 50
feet from the telephone modem.
To implement a telephone modem link, two telephone modems are required.
One modem must be located at the computer and one located at each remote
site requiring a Powermonitor. The single device port at the remote site must
be configured for an RS–232C communications port. The connection
diagram for the modem at the remote site is shown in Figure 3.3. Note that
this configuration (RS–232C) permits only one Powermonitor to be
connected to each modem.

Modem Configuration Information
Modems used with computers running the Powermonitor Software must be
fully Hayes compatible.
If the modems are configured via their communications ports, the
Powermonitor Software will configure them automatically using a set of
default commands. These commands assume that a standard Hayes modem
is being used. If you are using a modem which requires a unique command
set to configure it, refer to Appendix B for instructions on creating a special
MODEM.CFG file for Powermonitor Software to use.
If the modems are configured via hardware DIP switches or a similar
method, configure them to the specifications on next page.
Modems should be configured as follows:
The modem located at the destination site must be configured for
“auto–answer” mode. The modem connected to the computer running the
Powermonitor Software must be configured for “originate” mode.
Both modems must also be configured as follows:
1. Force the RS–232C Data Terminal Ready lead true.
2. Result codes must be sent as numbers.
3. Result codes must be sent by the modem.
4. Echo characters while in command state.
5. Do not force Carrier Detect lead true.
6. Single line connection.
7. Enable modem command recognition.
8. 8 data bits per byte.
9. No parity.
10. 1 stop bit.
The modem must be Hayes compatible. If you are using a sophisticated or
high speed modem, some of the advanced features need to be disabled.
To use a Telebit 3000 modem, disable flow control, disable data compression
and specify CTS operation and delay. Re–configure modem command
register as shown below: (This is an example only.)
AT Z Reset Modem
AT &RO CTS follows RTS
AT S26=1 RTS to CTS Delay Interval
AT S50=6 9600 Baud per second (V.32)

Installing The Software Onto A Hard Drive
The Powermonitor Software is designed to run either from the floppy disk it
comes on, or from a hard disk drive, onto which it can be copied.
If you wish to run the Powermonitor Software from the floppy disk, proceed
to Chapter 4 for instructions on starting and running the Powermonitor
Software.
If you wish to run the Powermonitor Software from the hard drive of your
computer, first perform the following steps to install the Powermonitor
Software onto the hard drive:
1. Create a directory called SP on your hard disk. You may select any drive
to create the directory on (C:, D:, etc.). The following instruction set
creates the directory on the C: drive:
C: <Enter>
MD SP <Enter>
2. Insert the Powermonitor Software program diskette into the A: drive of
your computer and copy the entire contents of the disk into the SP
directory on your hard disk. The following instruction assumes that the
SP directory was created on your C: drive. If this is not the case, replace
C: with the appropriate drive designation.
COPY A:*.* C:\SP <Enter>
3. Check that the SP directory on your hard disk contains the following files:
SP.EXE
SP.EXE is the Powermonitor Software program.
PASSWORD.CFG
Password.CFG is the Powermonitor Software password and setup file.
This file must be present to allow any protected functions to be performed
such as: changes to Powermonitor parameters, or relay control
commands. This file also allows communications setups to be saved.
