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

f. performance analysis and reporting
g. shadow billing
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

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.

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.):

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.

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

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)

Using The Software

Help/Message Line

The Powermonitor Software system provides a HELP/MESSAGE line at the
bottom of every screen, which serves two important purposes:

a. While any menu or screen is being displayed, a HELP line is

shown at the bottom indicating which keyboard keys are active on
the present screen. (Note: A quick keyboard reference for the
Powermonitor Software system is also given in Appendix D).

b. A MESSAGE line is used to display system status messages to the

operator. Examples of system status messages include password
prompts, modem connection status messages and system error
messages.

Screens And Functions

The Powermonitor Software automatically determines which type of remote
device it is communicating with, and configures the MAIN MENU
accordingly to provide the options specific to that device.

The MAIN MENU screen provides access to all of the Powermonitor
Software’s remote device data display and configuration screens and
functions, as well as the on–line HELP and the Powermonitor Software
PASSWORD screens.

F5 MIN/MAX LOG screen
F6 CONNECTION screen

Screen Descriptions

Detailed descriptions of each remote device data and configuration screen
can be found in Chapter 5, ‘‘Powermonitor Data Display and Configuration.”

The Powermonitor Software provides a security system to protect
Powermonitors from inadvertently:

a. having their relays manually operated/released.
b. having their kWH, kVARH or kVAH totals cleared, or Min/Max

Logs reset.

c. having any of their user–programmable operating parameters reset

from the computer.

The Powermonitor Software password is used for this purpose. Prior to any
of the above listed operations, the Powermonitor Software will prompt the
user for the required password. If the password entered by the operator is
incorrect, the Powermonitor Software will abort the operation.

When the Powermonitor Software is run for the first time, the Powermonitor
Software password is set to the single digit zero (“0”). It is recommended
that the user change this default password as soon as possible, using the
Powermonitor Software PASSWORD screen (see Figure 4.4 on Page 4–10).

Immediately prior to the operator being returned to DOS, the Powermonitor
Software will save the last information entered in the CONNECTION screen
(SITE ID, UNIT ID, COMM PORT, etc.) to a disk file.

When the Powermonitor Software is started again later, the previous
connection configuration will be loaded into the CONNECTION screen
automatically. This means the operator will not be required to re–enter data
in the CONNECTION screen fields, if connection to the same remote device
is desired. The operator need only position the cursor on the CONNECT
OPTION field and press <Enter> to reconnect to that device.

Important: The Powermonitor Software saves the connection setup to the
file in the SP disk directory named PASSWORD.CFG, which is the same file
containing the Powermonitor Software password. If this file is missing from
the SP directory, the Powermonitor Software will always display the default
communications options in the CONNECTION screen when the program is
first started.

Powermonitor Data Display And Configuration

This chapter describes the steps necessary to display real–time and logged
data from a Powermonitor, and how to configure the operating parameters of
the device.

Data Display Formats

Following connection to a Powermonitor (as described in Chapter 4) the
system operator can display data from that device by selecting the desired
data screen from the MAIN MENU. These include:

a. REAL–TIME
b. EVENT LOG
c. SNAPSHOT
d. STATUS (incl. Relay Status, Status Inputs, and Setpoint Status)
e. MIN/MAX

Displaying Device Data

To display data from a particular device:

1. Connect with the Powermonitor as described in Chapter 4 (if not
previously performed).

2. Return to the MAIN MENU by pressing <Esc>, select the desired data
screen using the cursor keys, and press <Enter>.

Alternately, the operator can use the shortcut keys to view data screens
directly, rather than using the MAIN MENU. Shortcut key functions are
listed in the HELP line at the bottom of the screen.

The most recent data for the selected device screen should appear almost
immediately.

Important: If the site is accessed via a modem that is not presently
connected, a series of messages will appear at the bottom of the screen
indicating modem connection status. It may take 30 seconds to establish
connection with the site before updated data will appear on the
Powermonitor.

5–1

Chapter 5

Powermonitor Data Display and Configuration

Important: An audible alarm (beep) will be encountered if a
communications failure occurs when attempting to display any device screen.
In this case, the operator should verify communication with the device by
entering the CONNECTION screen and checking that the CONNECT
STATUS field is reading CONNECTED. If this is not the case, attempt to
reconnect with the device as described in Chapter 4, ‘‘Using The Software.”
If connection cannot be accomplished, refer to Chapter 8,‘‘Troubleshooting.”

An example of a typical device data screen is provided in Figure 5.1.

Figure 5.1
Example of Powermonitor Data Screen

5–2

At the bottom of each data screen the UNIT ID indicates from which unit
data is presently being monitored. The DATE and TIME shown at the
bottom of some screens (ex. REAL–TIME and STATUS screens) indicates
the time at which the data was last updated.

The data shown on each screen will be continually updated as long as the
device is connected. The rate at which data is refreshed will depend upon the
baud rate of the communications link.

Displaying Additional Data

In the case of screens which contain too much information to be shown at
once, such as the SNAPSHOT LOG, the up/down arrow or PgUp/PgDn keys
can be used to scroll or page up/down through the data, respectively. The
left/right arrow keys can also be used to select any available adjacent screens
(ex. SNAPSHOT Left, Center, Right).

Chapter 5

Powermonitor Data Display and Configuration

If additional data is available, a message line at the bottom of the data screen
will tell the operator which key functions to use to view the data.

To Exit From Any Data Display Screen

To exit from any screen, the operator can either press the <Esc> key to return
to the MAIN MENU, or press one of the shortcut keys to display another
data screen directly.

Configuring Powermonitors

The Powermonitor Software gives the system operator the ability to remotely
view or reconfigure the DEVICE SETUP and SETPOINT/RELAY SETUP
parameters of a Powermonitor from the Master Display Station.

Displaying The Setup Or Setpoint Parameters Of Any Devices

All device configuration functions are accessed from the MAIN MENU. To
display data from a particular device:

1. Connect with the desired Powermonitor as described in Chapter 4.

2. Return to the MAIN MENU.

3. Place the cursor onto the DEVICE SETUP or SETPOINT/RELAY
SETUP field for the desired device (depending on which set of

Chapter 5

Powermonitor Data Display and Configuration

Important: Communication alarm conditions that were described for
displaying device data screens also apply to displaying configuration screens.

Important: Device configuration screens are not available to the operator if
the PASSWORD.CFG file is missing from the SP directory on disk.

Modifying Parameter Values

In the device configuration screens, the Powermonitor Software will prompt
the operator to enter the Powermonitor Software password. This is necessary
before any device parameters may be modified.

When working in the device configuration screens, the arrow keys are used
to position the cursor onto the desired parameter field. The cursor position is
indicated by a flashing parameter value.

Some parameter fields are changed by entering a numerical value. If an
attempt is made to set a parameter to a value outside its allowable limits, the
value is rejected. Should a value be rejected, the user must re–enter with a
proper value. The operator may also cancel the entry of any value by
pressing the <Esc> key.

Some parameter fields are changed by pressing the plus or minus keys which
cause the field to increment/decrement through a pre–defined range of
values, or number of parameter selections. This is indicated by +/– toggle
UP/DN appearing in the lower right hand portion of the screen.

Reconfiguring The Device With The New Parameter Values

The Powermonitor will be reconfigured using the new values entered into the
screen when the operator presses the <Esc> key to return to the MAIN
MENU. The <Esc> key, in this case, is used as a SAVE & EXIT command.

After transmitting the changes and returning to the MAIN MENU, it is

Event Log

The Powermonitor contains a record of events that is stored within its
internal nonvolatile memory. An event is defined as any alarm condition,
over/under limit condition, status input change, or relay operation. Also
included as events are changes in the device setup parameters and device
power–ups.

Figure 5.5
Event Log Screen

The EVENT LOG screen displays the record of device events that has been
up loaded by the Powermonitor Software system (see Figure 5.5).
Information is divided into six columns:

1. EVENT. This column describes the type of event that has occurred.
Examples of typical events include the occurrence of a device power–up,
a change in the device set–up parameters, setpoint alarms, a change in any
of the device’s four status inputs, and events that cause changes in any of
the three control output relays.

2. STATE. This column gives the current state of any alarms resulting
from the occurrence of an event. Examples of typical state messages
include the state of the alarm (ACTIVE or NORMAL) along with a relay
number if one is associated with the setpoint alarm. The manual
operation and release of relays is also indicated here.

3. VALUE. This column is reserved for numerical information that is
related to the event. Examples include parameter values that are
associated with the triggering of any setpoint alarm event.

4. RELAY. This column shows the state of the three on–board device relays
(R1, R2, and R3, respectively) immediately following the event (ON =
operated, OFF = released). Please note that the state of the relays may not
be associated with the occurrence of every event.

5. DATE. This column gives the date that the event occurred.

6. TIME. This column gives the date and time that the event occurred.

Status Data

The STATUS screen (Figure 5.9) displays and monitors the present state of
the three Powermonitor control relays, four status inputs, and any of
setpoints or alarms that are in an active condition. A description of the data
shown on the STATUS screen is given below.

Figure 5.9
Status Screen

5–10

Relay

This portion of the STATUS screen shows the present condition of the three
relays.

1. OFF. A relay is considered to be OFF when its normally–open contacts
are open (for Relay #1 this is R14/R11) and normally–closed contacts are
closed (R11/R12). This state occurs when the relay is not assigned to any
setpoint, or when the assigned setpoint is not in an active condition.

2. ON. A relay is considered to be ON when it has been activated by a
setpoint. In this state, the normally–open contacts have been closed and
the normally–closed contacts have been opened. This state occurs when
a relay has been assigned to a setpoint and the setpoint parameter value is
outside the bounds of its low or high limits.

Chapter 5

Powermonitor Data Display and Configuration

3. FORCED OFF. A relay is considered to be forced off when it has been

manually released by the operator from the keyboard. All device relays
can be manually released from the RELAY CONTROL section of the
STATUS screen.

4. FORCED ON. A relay is considered to be forced on when it has been

manually operated by the operator from the Main Menu. All relays can
be manually operated from the RELAY CONTROL section of the
STATUS screen.

Status Input

This portion of the STATUS screen displays the condition of the
Powermonitor’s four status inputs.

1. OFF. This state indicates that the voltage present at the Status Input

terminal is less than the INACTIVE voltage as specified in the
Publication 1400–800 ‘‘Bulletin 1400 Powermonitor Installation and
Operation Manual.”

2. ON. This state indicates that the voltage present at the Status Input

terminal is greater than the ACTIVE voltage as specified in the
Publication 1400–800 ‘‘Bulletin 1400 Powermonitor Installation and
Operation Manual.”

Count

This parameter displays the number of pulses (contact transfers) that have
been accumulated on the device’s Status Input #1 since the last time the
counter was cleared.

Active Alarms

This portion of the STATUS screen displays:

1. All of the user specified setpoints that are presently active. All 17
setpoints (if active) will be displayed in this area of the STATUS screen.

2. All other alarm conditions detected by the Powermonitor

k. SNAPSHOT PERIOD. Each Powermonitor provides a

SNAPSHOT log, allowing the device to store Average Volts,
Average Amps, kW, kVAR, kW Demand, Amp/kVA Demand,
Power Factor, Auxiliary Voltage Input, Frequency, kWH, kVARH,
and kWH Reverse readings at user defined intervals ranging from
1 sec. to 400 days. Position the cursor onto each of the four fields
provided and enter the desired total interval value.

l. DEMAND PERIOD and NUMBER OF DEMAND PERIODS.

The Powermonitor uses a “sliding window method” to calculate
kW Demand and Amps Demand. Both the DEMAND PERIOD (1
to 99 minutes) and NUMBER OF DEMAND PERIODS to be
averaged (1 to 15) are user programmable. This allows for
matching virtually any utility demand measurement method. Refer
to Publication 1400–800, ‘‘Bulletin 1400 Powermonitor Installation
and Operation Manual,” for additional information.

RELAY SETUP PARAMETERS. These parameters determine the
operation of the on–board relays.

m. RELAY MODE. This parameter is used only by the

Powermonitor to set the function of each relay. Each of the three
relays may be used for SETPOINT, kWH PULSE or kVAH PULSE
functions.

ATTENTION: When enabling the kWH and/or kVARH pulse
outputs, first check the device’s setpoint configuration to ensure

!

there will be no conflicts between the setpoint and pulse output
relay assignments.

n. RELAY # VALUE. The purpose of this parameter depends on the

relay mode set.
If the relay mode is SETPOINT, this parameter sets the duration of

the pulse output by the relay when the setpoint assigned to that
relay becomes active. Range of values is 1 to 65535 seconds. A
value of 0 will set the relay to latched operation, which provides a
transition rather than a pulse output.

If the relay mode is kWH or kVARH PULSE, this parameter sets
the number of kWH or kVARH between pulses. This is the
number of kW Hours or kVAR hours that must accumulate before a
pulse is generated on the indicated device relay. Range of values is
1 to 65535. A value of zero will disable the pulses.

Save & Exit

The Powermonitor will be reconfigured using the new values entered into the

If the user responds with a “Y”, then the Powermonitor Software will display
an appropriate message. If the user responds with an “N”, then
Powermonitor Software will display the message:

CLEARING OPERATION ABORTED

Upon completion of the CLEAR function, the Powermonitor Software will
return to the MAIN MENU screen.

The option CLEAR HOURS provides three sub–options to choose from,
following the entry of the correct password. The operator must then enter the
number “1” to clear kWH or “2” to clear the kVARH, or ‘‘3” to clear kVAH.
As above, the Powermonitor Software asks for confirmation to complete the
operation.

After entering this menu selection and successfully entering the SP software
password, the prompt “CLEAR ALL HRS, kWH, kVARH, OR kVAH –
(0/1/2/3) ?” will be displayed. By entering the value of 0, this will clear the
kWH, kVARH, and kVAH counters simultaneously.
NOTE: The kVAH option is displayed and cleared for only those
powermonitor units with firmware version 0.7 or later.

Manual Control Of Powermonitor
Internal Relays

This chapter describes how relay modes affect manual control operations,
and the steps required to perform manual control using the Powermonitor
Software.

The Powermonitor Software gives any system operator with the appropriate
software password the ability to manually control the on–board relays of any
Powermonitor directly from the computer running the Powermonitor
Software.

Operations include operate (or pulse), release, and return control to unit.
Refer to Publication 1400–800,‘‘Bulletin 1400 Powermonitor Installation and
Operation Manual,” for detailed descriptions of relay operation.

The Effect Of Relay Mode On Manual Control

The type of manual control possible for any Powermonitor relay will be
dependent on the RELAY MODE that has been defined for that relay.

Performing a manual OPERATE relay command may produce one of two
different conditions depending on the relay mode. A contact closure will be
produced if the relay is set for latch type operation (ie. OPERATED or
RELEASED) . A pulse output will be produced if the relay has been set for
pulse operation.

For the Powermonitor, the following rules apply. Relays assigned to kVA,
kWH, kVAH or kVARH PULSE mode will ignore all manual control
commands. Relays assigned to SETPOINT functions in latch mode will
respond to manual OPERATE, and RELEASE commands.

Important: During the duration of a relay pulse output, all other commands
to that relay will be ignored. This includes commands generated manually
by the Powermonitor Software operator or generated internally by the
Powermonitor as a result of an active setpoint condition.

Manual Control of Powermonitor Relays

Logging Of Relay Control Commands

Manual Relay Operations

The Event Logs of Powermonitors will log only commands which they
respond to. Powermonitors will not log relay commands which are ignored
due to the conditions outlined above.

To manually operate a Powermonitor relay, select the OPERATE RELAY
function by selecting the RELAY CONTROL option from the MAIN
MENU. This will display the RELAY CONTROL SCREEN as shown in
Figure 6.1.

Figure 6.1
Relay Control Screen

6–2

Upon entry to this screen, the user is required to enter the Powermonitor
Software password. Failure to enter the correct password will cause
Powermonitor Software to exit the RELAY CONTROL SCREEN and return
to the MENU screen.

After pressing <Enter>, the user is asked what operation to perform on the
selected relay. Valid operations are:

a. 1 – NORMAL. This operation will cause the control of the

indicated relay to return to the device setpoints if the relay is in
latch mode.

This command has no effect if the relay is in any pulse mode.

b. 2 – FORCED ON. This operation will cause the indicated relay

number to operate. if the relay is in latch mode, or pulse if the relay
is in pulse mode.

Chapter 6

Manual Control of Powermonitor Relays

An operate operation causes normally open contacts (RX4 / RX1)
to close, and normally closed contacts (RX1 / RX2) to open.

A pulse operation will cause normally open contacts (RX4 / RX1)
to close, and normally closed contacts (RX1 / RX2) to open for a
duration specified by the VALUE parameter for the device, after
which the relay will return to its previous state.

This command will override the setpoint control functions.

c. 3 – FORCED OFF. This operation will cause the indicated relay

number to release if the relay is in latch mode. This causes
normally open contacts (RX4 / RX1) to open, and normally closed
contacts (RX1 / RX2) to close.

This command has no effect if the relay is in pulse mode.
This command also overrides the setpoint control functions.

After the type of relay operation has been selected, the operator is prompted
with:

CONFIRMING OPERATION OF RELAY (Y/N)?

This provides an added level of security by forcing the operator to confirm
the intention to execute the command.

If “Y” is selected, the Powermonitor responds to the Powermonitor Software
with the outcome of the operation. A relay successfully operated or released
manually by the operator will be shown as having been FORCED ON or
FORCED OFF. If control is returned to the Powermonitor, the relay status
will be shown as either ON or OFF.

If “N” is selected, Powermonitor Software will display the message:

RELAY OPERATION ABORTED

ATTENTION: 1) Manual operation or release of a relay
overrides the normal setpoint operation of that relay.

!

2) In the event of a power interruption to the device, all relays
revert to the normal state, with all setpoint functions re–enabled.

Printing Log Disk Files

This chapter discusses the printing of log disk files. Instructions will indicate
how to save, locate, and name your log files.

An important feature of the EVENT, MIN/MAX or SNAPSHOT LOG
screens is the ability to store the contents of the logs into disk files. These
files can later be displayed on the computer screen or printed to a connected
dot–matrix printer using the standard DOS commands TYPE or PRINT,
respectively.

Saving A Log To Disk

Location And Filenames Of Log Files

Saving the contents of the EVENT, MIN/MAX or SNAPSHOT LOG to a
disk file is performed by depressing the F7 function key (SAVE DISK) while
viewing any of the three screens.

Log files will be stored on the current directory from which the
Powermonitor Software was invoked and will be labelled in the following
way:

a. An EVENT LOG file will be labelled as EVNTxxxx.LOG, where

xxxx is the UNIT ID of the remote device currently being viewed.

b. A SNAPSHOT LOG file will be labelled as SNAPxxxx.LOG,

where xxxx is the UNIT ID of the remote device currently being
viewed.

c. A MIN/MAX log file is labelled as MNMXxxxx.LOG where xxxx

is the UNIT I.D. of the Powermonitor currently being used.

Chapter 7

Printing Log Disk Files

Contents Of Log Files

Printing Log Disk Files

Headers displayed in the log screens in the Powermonitor Software are saved
to disk with the data log. This means log files printed via DOS include the
column labels describing the data listed in each column.

Data entries in log disk files are organized with the oldest data at the
beginning of the file, and the most recent data at the end of the file. Note
that this is opposite to the order in which log data is displayed on the screen
in the Powermonitor Software.

If an EVENT, MIN/MAX or SNAPSHOT LOG for a selected device has
previously been saved to a disk file, the Powermonitor Software will append
the new log data for that device to the end of the file. However, the
Powermonitor Software will first determine if there are any duplications of
events or snapshots between the current log and the previously stored log.
The Powermonitor Software will not store duplicates of the same event or
snapshot.

The Powermonitor Software will continue to append data to the end of
existing log files on disk each time the operator uses the SAVE DISK
function. For this reason, the operator may be required to occasionally
remove large log files from the hard disk to free up disk space.

Logs saved to disk can be displayed on the screen or printed to a printer
through DOS using standard TYPE or PRINT commands. For example, to
print an EVENT LOG file for a remote device with a UNIT ID of 3099, go to
the directory from which the Powermonitor Software was originally invoked,
then use the command:

Printer Considerations

7–2

PRINT EVNT3099.LOG

SNAPSHOT parameter data normally displayed by the Powermonitor
Software using three separate screens (ie. SNAPSHOT LOG Left, Center,
and Right) is saved to disk in one 14 parameter wide print format.

To allow SNAPSHOT LOG disk files to be printed in their intended full 14
parameter width, a 132 column printer set to COMPRESSED mode must be
used. If any other printer configuration is used, the printer will be forced to
wrap–around line segments, causing headers to be misaligned with data
columns, as rows of data become interleaved.

EVENT LOG and MIN/MAX disk files may be printed using a standard
80–column printer.

Troubleshooting

The Powermonitor Software will alert the system operator to conditions that
will cause incorrect operation of the software. This is accomplished by
displaying messages at the bottom of the computer screen and, in some
cases, annunciating an audible alarm.

Introduction

What Is RS–232C?

This document gives a brief overview and comparison of the RS–232C and
RS–485 communication standards, along with a list of factors to consider
when deciding which of the standards is best suited to your metering
application.

Also included is an application note covering using modems with the
Powermonitor Software.

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.

RS–232C is an electrical standard used to provide serial communications
between electronic devices.

IBM PC–AT/286/386 or compatible computers have the ability to
communicate via RS–232C when a serial communications card or “PORT”
is installed into one of its internal PC expansion slots. The connector for this
port is usually located at the back of the computer.

When two electronic devices are equipped with an RS–232C port, they can
be connected together via an RS–232C cable over which information is
transferred. The minimum cable requirements for RS–232C is a 22 AWG
shielded three conductor cable.

Normally, the maximum length of cable used to connect two electronic
devices via RS–232C is 50 feet.

B–1

Appendix B

Communications Application Note

What Is RS–485?

RS–485, like RS–232C, is also an electrical standard used to provide serial
communications between electronic devices.

IBM PC–AT/286/386 or compatible computers can also communicate via
RS–485. This requires the installation of an RS–485 communications card or
“PORT” into one of the internal PC expansion slots. Alternatively, if the
computer is already equipped with an RS–232C serial port, an external
RS–232C to RS–485 converter device can be used to convert the existing
RS–232C port to RS–485.

When two electronic devices are equipped to communicate via RS–485, they
can be connected together via an RS–485 cable over which information is
transferred. This RS–485 cable consists of a 22 AWG shielded two
conductor twisted pair cable.

One of the advantages of RS–485 over RS–232C is that RS–485 can
communicate over much greater cable distances. The maximum length of an
RS–485 cable used to connect electronic devices is 4000 feet.

The most important feature of RS–485 communications is that it allows up
to 32 devices to be connected anywhere along the length of the two
conductor cable. This feature has important benefits for customers who wish
to connect a large number of Powermonitors to a single computer and to
display the data from any of the devices. RS–232C does not have this ability
as it allows only the connection of one device to each RS–232C serial port.

Summary Of Advantages And
Disadvantages Of RS–232C vs
RS–485

B–2

Advantages Of RS–232C:

1. Very easy to install.

2. Allows single cable connection from the computer to the Powermonitor.

Disadvantages Of RS–232C

1. Only one device can be connected to each computer RS–232C port.

2. Maximum cable length limitation = 50 feet.

3. RS–232C is more susceptible to electrical noise than RS–485.

Advantages Of RS–485

1. Very easy to install.

2. Up to 32 devices can be connected to a single computer serial port.

3. RS–485 can communicate over very large distances, up to 4000 feet.

4. RS–485 has greater immunity to electrical noise than RS–232C.

Disadvantages Of RS–485

1. Requires an RS–485 communications card to be installed into an empty
slot in the computer or an external RS–232C to RS–485 converter device.

Appendix B

Communications Application Note

Considerations When Choosing Powermonitors With Communications Capability

1. If you wish to display the data measured by a Powermonitor on your
computer, you have three options:

a. Use the purchased copy of the Powermonitor Software.
b. You can write your own program to up load and display the data

measured by the device.

c. You can purchase the Bulletin 6190–PMO ControlView Option

package. It requires a PLC–5 and the Bulletin 6200 PLC software
package.

2. If you wish to connect your computer to a single device, then you have
the option of communicating via RS–232C or RS–485.

If the computer is located less than 50 feet from the device you wish to
communicate with, then RS–232C will be suitable.

If the computer is located more than 50 feet from the device (but less than
4000 feet) then it is best to use RS–485 communications. In this case,
you will be required to purchase either:

a. an RS–485 communications port for the computer

or

b. an RS–232C to RS–485 converter device (if the computer is

already equipped with an RS–232C port).

3. If you wish to connect your computer to more than one device, then only
RS–485 will permit this.

ATTENTION: Powermonitors that communicate via the
RS–232C standard should never be connected to devices that

!

communicate via RS–485. If this is attempted, damage to the
RS–485 devices will occur

DISTANCE X

NOTE: When an intermediate terminal block is used to connect any device to the RS–485 bus, the length of the cable segments between the device and the terminal
block must be taken into account when calculating the overall length of cable (4,000 ft. max.). This length is equal to 2 times distance X in the diagram.

Calculating Overall Cable Length

When determining the overall length of an RS–485 communication straight
line or loop connection, it is important to account for all cable segments.
For example, when RS–485 connections to the device are made via an
intermediate terminal block, the lengths of cable between the device and the
terminal block must be added to the total cable distance (see Figure B–3).

Using Modems

If communications over a telephone network is used with modems, each
modem will require configuration.

DIP Switch Configuration

If the modems used are configured using hardware DIP switches or a similar
method, set the DIP switches to provide the functionality outlined in Chapter
3, Section 3.1.3.

Configuration Via
Communications – Standard
Modem Setup

B–6

For modems that are configured via their communications port, the
Powermonitor Software automatically executes a predefined procedure at the
time that the operator selects the MODEM (TOUCH TONE) or MODEM
(PULSE) option in the CONNECTION screen.

This procedure automatically transmits two sets of commands to the
modem(s) which will configure both a Hayes–compatible 2400 baud modem
and a Hayes–compatible 9600 baud modem.

Appendix B

Communications Application Note

Configuration Via
Communications – Custom
Modem Setup

If the modem you are using requires a unique set of configuration
commands, a modem configuration file with the name MODEM.CFG must
be created and placed in the SP directory. This file may be created using any
ASCII text editor; however, a quick way to create the file is to use a simple
DOS line editor. This can be run by using the following DOS command:

TYPE CON MODEM.CFG <Enter>

The operator should then type in the sequence of modem commands
necessary to configure the device. The device must be configured to provide
the functionality outlined in Chapter 3, ‘‘Installation.” Refer to the manual
for the modem to determine the communications commands necessary to
perform the configuration.

ATTENTION: It is extremely important that information is
entered correctly into the MODEM.CFG file. Any errors may

!

incorrectly configure a modem, which may cause malfunctions
when running the Powermonitor Software.

When the complete string has been entered, press:

Ctrl + Z
to escape from the DOS line editor.

Loading Event, MIN/MAX, or Snapshot
Log Files Into Lotus

Spreadsheet programs such as Lotus 123 can be used to analyze,
sort, perform calculations, and graph the data contained in the
snapshot, MIN/MAX, and event log files. To use the Snapshot
logs with Lotus 123, boot up Lotus, then import the
SNAPxxxx.log file using the following procedure:

1. Import the file by using the following Lotus command:
/file import text (filename = snapxxxx.log)

This will result in the snapshot file being loaded into the
spreadsheet as a text file. It now has to be converted into a
standard Lotus work sheet by using the “parse” command.

2. Put the cursor on cell A2; the first cell below the counter line
and perform the following commands:

a. Create a format line: /data parse format_line create
b. Edit the format line to define the first column as a date

column:
(/data parse format_line) edit and change the first
V>>> to D>>>.

c. Define the top left and bottom right corners of the data

which you wish to parse:

d. Define the output location where the parsed data will

be located (normally a column A cell a few lines below
the text data):

(/data parse) output–column

e. Do the parse: (/data parse) go

The original test format data should now be reproduced
in a WKS format just below the original data.

(/data parse) input–column

3. The text data should now be deleted:
/work sheet delete rows 1 to the beginning of the parsed data

4. The first two data and time columns need to be formatted to
display correctly. Format the entire first column to display
dates:
/range format date 5–short–intnl

5. Increase the width and change the format of the second
column to display the time:
/work sheet global column–width 10/range format date time
3–long intnl

6. Save the data as a standard Lotus file.

Loading Logs into Lotus

AppendixAppendix

The snapshot log is now in a standard Lotus format. Standard
Lotus commands can now be used to sort, perform calculations,
and graph the data.

If you are going to be using this procedure frequently, a Lotus
Macro should be written to automate the process.
