Display Diagnostics

The display may indicate a connection error as shown on the left picture if it fails to establish a connection with the meter. Check the connection between the display module and the meter body. If the error message is still displayed, contact your local distributor.

Numeric LED Display

The meter has a simple user interface that allows you to view numerous measurement parameters by scrolling through different display pages. The

32 Series PM172 Powermeters

Chapter 3 Display Operations

Data Display numeric LED display shows up to three parameters at a time. Small rectangular or triangular LEDs at right and below the display indicate the displayed parameters and their measurement units.

The display layout may change depending on the meter type and mode of operation. There are three modes of display operation: data display, status display, and programming mode display.

Load Bar Graph

The load bar graph displays the amount, in percent (40% to 110%), of the present current load with respect to user-defined nominal load current. The reference nominal current can be set up in amps through the Display Setup menu. If it is set to 0 (default), the current load is referenced to the specified

CT primary current.

Energy Pulse LED

The PM172E and PM172EH have a red “Energy Pulse” LED. It flashes at a constant rate when a load is applied to the meter. There are two modes of

LED operation: normal and test. In normal mode, the LED pulses indicate imported Wh at a rate of 1,000 pulses per kWh in secondary units. In test mode, the LED pulses indicate either imported Wh, or imported (inductive) varh at a rate of 10,000 pulses per kWh/kvarh. The energy test mode can be enabled through the Display Setup menu. When in test mode, the energy and demand accumulators do not account for consumed energy.

Port Activity LEDs

The meter has two yellow LEDs “COM1” and “COM2”, which indicate activity on the two communication ports. The port’s LED flashes when the port is receiving or transmitting data. With the Ethernet or Profibus option, the

“COM1” LED flashes constantly regardless of the port activity.

When the display module is connected remotely through a 3-wire RS-485 interface, the “COM1” LED indicates the display port activity, while the

“COM2” LED is not operational.

Navigation Buttons

The PM172 is provided with six push buttons that are normally used to navigate between different measurement displays. In programming mode, the buttons access the device setup menus and the default factory-set device settings can be changed.

Data Display

In data mode, the display is normally updated once per second; you can adjust the display update rate via the Display Setup menu.

Display Features

Measurement Units

Currents are always displayed in amperes with two decimal places.

Measurement units for voltage and power depend on the connection scheme of the meter:

• When direct wiring is used, voltages are displayed in volts with one decimal place, and power in kilowatts with three decimal places.

Series PM172 Powermeters 33

Chapter 3 Display Operations

• When wiring via PT is used, for the PT ratio up to and including 4.0, voltages are displayed in volts, and power in whole kilowatts.

Data Display

• For the PT ratio above 4.0, voltages are displayed in kilovolts, and power in megawatts with three decimal places.

The small round “Kilo” and “Mega” LEDs light up showing the appropriate measurement units for a displayed page.

Primary and Secondary Volts

Volts can be displayed in primary (default) or secondary units. The volts display mode can be changed through the Display Setup menu.

Phase Power Readings

In configurations with the neutral wire, in addition to total three-phase powers, the meter can show per-phase power readings. By default, they are disabled. See Display Setup on how to enable per-phase power readings in your meter.

Fundamental Component

The meter can display total power factor and active power for the fundamental component if it is enabled through the Display Setup menu.

Whenever phase power readings are allowed, the PM172 also displays perphase power factor and active power for the fundamental component.

Auto Return

If no buttons are pressed for 30 seconds while the display Auto Return option is enabled, the display automatically returns to the main screen from any other measurement display or programming mode.

The Auto Return option can be enabled through the Display Setup menu

Auto Scroll

If no buttons are pressed for 30 seconds while in the common measurements display, and the Auto Scroll option is enabled in the meter, the display automatically scrolls through all available pages. The scroll interval can be adjusted through the Display Setup menu.

To stop auto scrolling, press briefly the SCROLL button.

In Data Display mode, the navigation buttons function as follows.

The MIN/MAX button switches to the Min/Max - Maximum Demands display pages. When briefly pressed again, it switches back to the common measurements display.

The THD/TDD button in the PM172P and PM172E switches to the Total

Harmonics display. The similar H/ESC button in the PM172EH switches between different harmonic displays: Total Harmonics, Individual Harmonics,

Harmonic Powers, and Harmonic Energies. When briefly pressed once again, it switches back to the common measurements display

The UP and DOWN arrow buttons, labeled by arrowheads, scroll forwards and backwards through the display pages. Pressed briefly, they move one page forward or backward. If you hold down the button, the display pages are scrolled at rate of a twice per second.

34 Series PM172 Powermeters

Chapter 3 Display Operations

Data Display

Pressing both the UP and DOWN arrow buttons together returns to the first page within the current display.

The SELECT button operates once it’s released. The button has two functions:

When pressed briefly, it switches to programming mode.

When pressed together with the ENTER button for more than 5 seconds, it resets Min/Max records, maximum demands, or energies depending on the currently displayed page. If the meter is password protected and a simple reset of data from the display is not allowed, the action has no effect.

The ENERGY button switches to the Energy display in the PM172E and

PM172EH. In the PM172P, the button is not operational. If TOU registers are configured in the meter, you can repeatedly press this button to scroll through all available TOU registers. When briefly pressed once again, it switches back to the common measurements display

Simple Reset of Accumulated Data

When the meter is not password protected, or the simple reset of data is allowed from the display regardless of the security setting (see “Display

Setup”), the meter allows the simple “two-button’ reset of the Min/Max registers, maximum demands, energies, and counters from the data display mode without entering the reset menu:

1. Select a display page where the data you want to reset is displayed:

Min/Max log - select a Min/Max page from the Min/Max Display.

Ampere and volt maximum demands - select the ampere or volt maximum demand page from the Min/Max Display.

Power maximum demands - select the power maximum demand page from the Min/Max Display.

Total and phase energies - select a total energy, or phase energy page from the Energy Display.

Counters – select a counter page from the Status Display

2.

While holding the SELECT button, press and hold the ENTER button for about 5 seconds. The displayed data is reset to zero.

Configuring GE EGD Production Exchanges

The PM172 provides a GE EGD (Ethernet Global Data) data producer that supports four data exchanges. Each data exchange is individually configurable and can produce and send data to the same or to different consuming nodes. For EGD implementation and configuration details, see the PM172 GE EGD Communications Protocol Reference Guide.

To enter the Setup dialog, select the device site from the list box on the PAS toolbar, select Communications Setup from the Meter Setup menu, and then click on the GE EGD Producer Setup tab.

62

To configure an EGD exchange:

1. Select a desired exchange ID.

2. Specify a destination IP address of the data-consuming node.

3. Specify the production period for the exchange. The

PM172 exchanges provide production rates from 70 ms to

10 minutes in 10 ms increments. Though lower settings are allowed, the actual production period in most cases will not be less than 70 ms.

4. Select “Enabled” in the Exchange Status box to enable the exchange operations.

5. Define address ranges for the points to be sent via the exchange and the data element type for each address range. Up to 30 point ranges can be selected for each exchange that may identify a single point or a range of contiguous points.

Specify the data ranges using the range start point and end point identifiers (ID) in decimal notation. For the available device data points and their IDs, refer the

Series PM172 Powermeters

Chapter 4 PAS Application Software

Configuring Communications in your Meter

PM172 GE EGD Communications Protocol Reference

Guide.

Select a desired data type for the point range. Data transferred through the exchange can be represented in word (16-bit) or double word (32-bit) integer format, or in

IEEE single precision floating-point format.

As you specify an address range for the exchange, PAS immediately shows you the data offset in bytes in the production data area for the following range. Each exchange can send a total of 480 bytes of production data. PAS automatically truncates your range if you specify more data than the exchange can accommodate.

To indicate the end of the address range list, put a zero start point ID in the range following the last range you specified.

6. Click on Send to download your new setup to the meter.

The device will reject your setup if you specified an inexistent start point ID for one of the address ranges. If you specified more points in a range than the device can provide, it truncates the range to the maximum number of points available.

From this dialog box, you can also temporarily put a configured exchange into the pending (disabled) state, and then resume (enable) it whenever needed.

NOTE

When you change the consumer IP address for an exchange through the

Ethernet, the device port restarts so communications will be temporarily lost.

You may need to wait some additional time until PAS restores a connection with your device.

When the daylight saving time is enabled, the meter automatically advances the device clock one hour (by default at 02.00 AM) when daylight saving time begins and puts the clock back one hour (by default at 02.00 AM) when it ends. The default daylight saving time change points are preset for the

U.S.A.

The daylight saving time option is disabled in the PM172 by default. If the daylight saving time option is disabled, you need to manually adjust the device clock for daylight saving time.

Time Synchronization Pulses

External time synchronization pulses can be delivered through one of the digital inputs. If a digital input is selected as the time synchronization source, the edge of an external pulse adjusts the device clock at the nearest whole minute. The time accuracy could be affected by the debounce time of the digital input, and by the operation delay of the external relay.

Using Digital Inputs

The meter is provided with two digital inputs that can trigger the alarm/control setpoints to give an alarm on input status change, or can be linked to the energy/TOU registers to count pulses from external watt meters, or gas and water meters.

To configure them in your device, select the device site from the list box on the PAS toolbar, select General Setup from the Meter Setup menu, and then click on the Digital Inputs tab.

Using Relay Outputs

The PM172 is equipped with two relays. Each relay can be operated either locally from the alarm/control setpoints in response to an external event, or by a remote command sent through communications, and can also be linked to an internal pulse source to produce energy pulses.

KYZ mode: the relay generates transition pulses. The relay changes its output state upon each command and remains in this state until the next command.

With normal polarity, the relay is normally de-energized in its non-active state and is energized in its active

(operated) state.

With inverting polarity, the relay is normally energized in its non-active state and is de-energized in its active

(operated) state. It is called failsafe relay operation.

Applicable for latched relays.

In non-retentive mode, the relay always returns to its non-active state upon power up.

In retentive mode, the relay status is restored to what it was prior to loss of power.

The actual pulse width is a multiple of the 1-cycle time rounded to the nearest bigger value.

The pause time between pulses is equal to the pulse width.

Programming Analog Inputs

General Meter Setup

The PM172 can be provided with two optional analog inputs with options for

0-1mA, ±1mA, 0-20mA or 4-20mA input currents, depending on the order.

Inputs with 0-1mA and ±1mA options can accept ×200% overload currents, i.e., can actually accommodate currents in the range of 0-2 mA and ±2mA.

The meter automatically converts the analog input readings received from the analog-to-digital converter to the user-defined engineering scale and shows the input values in true engineering units, for example, in volts, amps, or degrees, with the desired resolution.

To configure the Analog Inputs in your device, select General Setup from the

Scaling Non-directional Analog Inputs

For non-directional analog inputs with the 0-1mA, 0-20mA and 4-20mA current options, provide both zero and full engineering scales. Each of the scales operates independently.

Scaling ±1mA Analog Inputs

For directional ±1mA analog inputs, you should provide only the engineering scale for the +1 mA input current. The engineering scale for the 0 mA input current is always equal to zero. The device does not allow you to access this setting. Whenever the direction of the input current is changed to negative, the device automatically uses your full engineering scale settings for +1 mA with a negative sign.

Scaling Analog Inputs for 0-2 mA and ±2 mA

The input scales for 0-1 mA and ±1 mA analog inputs are always programmed for 0 mA and +1 mA regardless of the desired input range. If you want to use the entire input range of 2 mA or ±2 mA, set the analog input scales in your device as follows:

0-2 mA: set the 1 mA scale to 1/2 of the required full scale output for uni-directional parameters, and set the 0 mA scale to the negative full scale and the 1 mA scale to zero for bi-directional parameters.

±2 mA: set the 1 mA scale to 1/2 of the required full-scale output for both uni-directional and bi-directional parameters.

For example, to convert voltage readings from the analog transducer that transmits them in the range of 0 to 2 mA to the range 0 to 120V, set the full range for the +1 mA analog input to 60V; then the 2 mA reading is scaled to

120V.

Programming Analog Outputs

The meter can be ordered with two optional analog outputs with options for

0-1mA, ±1mA, 0-20mA or 4-20mA output currents.

The 0-1mA and ±1mA current outputs provide a 100% overload, and actually output currents up to 2 mA and ±2mA whenever the output value exceeds the engineering scale set for the 1 mA or ±1mA.

To configure the Analog Outputs in your device, select General Setup from the Meter Setup menu, and then click on the Analog Outputs tab. If you are programming your device online, analog outputs are designated as not available if they are not present in the device.

74

When you select an output parameter for the analog output channel, the default engineering scales are set automatically. They represent the maximum available scales. If the parameter actually covers a lower range, you can change the scales to provide a better resolution on the analog outputs.

Scaling Non-directional Analog Outputs

When programming scales for non-directional analog outputs with a 0-1mA,

0-20mA or 4-20mA current option, you can change both zero and full engineering scales for any parameter. The engineering scale need not be symmetrical.

Scaling Directional Power Factor

The engineering scale for the signed power factor emulates analog power factor meters. The power factor scale is -0 to +0 and is symmetrical with regard to

±1.000 (-1.000 ≡ +1.000). Negative power factor is scaled as

-1.000 minus measured value, and non-negative power factor is scaled as

+1.000 minus measured value. To define the entire power factor range from

-0 to +0, the default scales are specified as -0.000 to 0.000.

Scaling ±1mA Analog Outputs

Programming engineering scales for directional ±1mA analog outputs depends on whether the output parameter represents unsigned (as volts and amps) or signed (as powers and power factor) values.

If the output value is unsigned, you can change both zero and full engineering scales.

If the parameter represents a signed (directional) value, you should provide only the engineering scale for the +1 mA output current. The engineering scale for the 0 mA output current is always equal to zero for all values except the signed power factor, for which it is set to 1.000 (see “Scaling Directional

Power Factor” above). The device does not allow you access to this setting if the parameter is directional. Whenever the sign of the output parameter is changed to negative, the device automatically uses your full engineering scale settings for +1 mA with a negative sign.

Series PM172 Powermeters

Chapter 4 PAS Application Software

General Meter Setup

Scaling Analog Outputs for 0-2 mA and ±2 mA

The output scales for 0-1 mA and ±1 mA analog outputs are programmed for

0 mA and +1 mA regardless of the desired output current range. To use the entire output range of 2 mA or ±2 mA, set the analog output scales in your device as follows:

0-2 mA: set the 1 mA scale to 1/2 of the required full scale output for unidirectional parameters, and set the 0 mA scale to the negative full scale and the 1 mA scale to zero for bi-directional parameters.

±2 mA: set the 1 mA scale to 1/2 of the required full-scale output for both uni-directional and bi-directional parameters.

For example, to provide the 0 to 2 mA output current range for volts measured by the meter in the range of 0 to 120V, set the 1 mA scale to 60V; then the 120V reading will be scaled to 2 mA.

Programming the Analog Expander

Your meter can support up to two analog expanders that are connected through a serial RS-422 interface to the meter port COM2. Each expander has its own address 0 or 1 on the serial interface and provides 8 analog channels with options for 0-1mA, ±1mA, 0-20mA or 4-20mA output currents.

To configure the Analog Expander outputs in your device, select General

Setup from the Meter Setup menu, and then click on the Analog Expander tab.

The expanded analog outputs are enumerated in the following manner: analog output channels 1 through 8 are associated with the analog expander with address 0, while channels 9 through 16 are associated with the analog expander with address 1.

The available analog expander outputs options are described in the following table.

Counter Value box, and then click Send.

Using Periodic Timers

The PM172E and PM172EH provide two programmable interval timers that can be used for periodic recording and triggering operations on a time basis through the Control Setpoints. When a pre-programmed timer interval expires, the timer generates an internal event that can trigger any setpoint

(see “Using Alarm/Control Setpoints”).

To configure the device timers, select General Setup from the Meter Setup menu, and then click on the Periodic Timers tab.

To run a periodic timer, specify a non-zero time period for the timer. The time period can be set from 1 to 9999 seconds.

To stop a timer, set the time period to zero.

Using Control Setpoints

The PM172 has an embedded logical controller that runs different actions in response to user-defined internal and external events. Unlike a PLC, the meter uses a simplified programming technique based on setpoints that allows the user to define a logical expression based on measured analog and digital values that produce a required action.

Series PM172 Powermeters 77

Chapter 4 PAS Application Software

General Meter Setup

The meter provides 16 control setpoints with programmable operate and release delays. Each setpoint evaluates a logical expression with up to four arguments using OR/AND logic. Whenever an expression is evaluated as

“true”, the setpoint performs up to four concurrent actions that can send a command to the output relays, increment or decrement a counter, or trigger a recorder.

The logical controller provides very fast response to events. The scan time for all setpoints is 1 cycle time (16.6 ms at 60Hz and 20 ms at 50/400 Hz).

To program the setpoints, select General Setup from the Meter Setup menu, and then click on the Control/Alarm Setpoints tab.

Chapter 4 PAS Application Software

General Meter Setup

Setpoint #1 is factory preset to provide standard periodic data logs on a 15minute time basis. It is linked to the device clock and runs data logs #1 and

#2 at 15-minute boundaries of an hour.

Using Logical Expressions

Logical operators OR/AND are treated in a simplified manner. They have no specific priority or precedence rules.

Any trigger condition bound to the logical expression by the OR operator and evaluated as “true” will override any preceding condition evaluated as “false”.

Similarly, any trigger condition evaluated as “false” and bound by the AND operator will override any condition evaluated before it as “true”.

To avoid confusion, it is recommended not to alternate different logical operators in one expression. Instead, bring all conditions that use the same logical operator together at one side of the expression, and the others - at the opposite side.

To explicitly override all other conditions with the critical trigger, put it at the end of the expression using the OR operator if you want the setpoint to be operated anyway when the trigger condition is asserted, and with the AND operator, if the setpoint should not be operated while the critical trigger is not asserted.

Using Numeric Triggers

For numeric (analog) triggers, a setpoint allows you to specify two thresholds for each trigger to provide hysteresis (dead band) for setpoint operations.

The Operate Limit defines the operating threshold, and the second Release

Limit defines the release threshold for the trigger. The trigger thresholds are specified in primary units.

If you do not want to use hysteresis for the trigger, set the Release Limit to the same as the Operate Limit.

Using Binary Triggers

Binary (digital) triggers, like digital inputs, relays, or internal static and pulsed events, are tested for ON (closed/set) or OFF (open/cleared) status.

The binary events are divided into two types: static events and pulsed events. Static events are level-sensitive events. A static event is asserted all the time while the corresponding condition exists. Examples are digital inputs, relays and event flags.

Pulsed events are edge-sensitive events with auto-reset. A pulsed event is generated for a trigger only once when a positive transition edge is detected on the trigger input. The examples of pulsed events are pulse inputs

(transition pulses on the digital inputs), internal pulsed events (energy pulses and time interval pulses), and events generated by the interval timers. The logical controller automatically clears pulsed events at the end of each scan, so that triggers that used pulsed events are prevented from being triggered by the same event once again.

Using Event Flags

The PM172EH provides 8 common binary flags, called event flags, which can be individually set, cleared and tested through setpoints and via communications.

Event flags can be used in different applications, for example, to transfer events between setpoints in order to expand a logical expression or a list of actions that have to be done for a specific event, or to externally trigger setpoint actions from the SCADA system or from a PLC through communications.

Using Interval Timers

The PM172E and PM172EH provide two interval timers that are commonly used for periodic recording of interval data at the time of the fault or in the presence of other events detected by a setpoint. The timers can be

Series PM172 Powermeters 79

Chapter 4 PAS Application Software

General Meter Setup programmed to generate periodic events at user-defined intervals (see

“Using Periodic Timers”).

Interval timers are not synchronized with the clock. When you run a timer, it generates a pulsed event that can trigger a setpoint if you have put the timer into a list of the setpoint triggers. When the setpoint event is asserted, the timer is restarted, and then generates the next event when the timer interval expires.

If you want to record interval data at predefined intervals without linking to other events, just select a timer as a setpoint trigger and specify a data log file you want to use for recording, in the setpoint actions list. If you want the periodic data to be recorded in presence of a specific event, select triggers that will identify your event, and then add the timer at the end of the trigger list using the AND operator.

Using Time Triggers

If you want the setpoint actions to be synchronized with the clock, for example, to provide synchronous recording interval data each 15 minutes or each hour, or to output time pulses through relay contacts, use the time triggers that generate static events synchronized to the device clock.

You can exercise the default setting for Setpoint #1 in your device as an example of using time triggers. The setpoint is pre-programmed for data profiling at 15-minute intervals using data logs #1 and #2.

Using the Voltage Disturbance Trigger

The PM172EH provides the voltage disturbance trigger (found under the

VOLT DISTURB name) that detects all types of the voltage waveshape faults on any phase caused by fast transient voltages. You can use it for recording disturbances.

The operate threshold for the voltage disturbance trigger defines the maximum allowable voltage deviation from the steady-state level above which the device will declare a waveshape fault. By default, it is specified as a percent of the nominal device voltage. If you wish to use volts units instead, you can select the desired voltage disturbance units from the

Preferences tab in the Tools/Options/Preferences dialog.

Ì

The voltage waveforms in 4LN3, 4LL3, 3LN3, 3LL3, 3BLN3 and 3BLL3 wiring modes represent line-to-neutral voltages; otherwise, they will be lineto-line voltages. Take it into account when specifying the nominal device voltage that is used as a reference for the disturbance trigger.

The trigger does not respond to slow voltage variations whenever the voltage rise above or drop below the specified threshold takes longer than 1 cycle time.

Delaying Setpoint Operations

Two optional delays can be added to each setpoint to extend monitoring setpoint triggers for a longer time before making a decision on whether the expected event occurred or not. When a delay is specified, the logical controller will change the setpoint status only if all conditions are asserted for a period at least as long as the delay time.

Note that you cannot use delays with pulsed events since they are cleared immediately and will no longer exist on the next setpoint scan.

Using Setpoint Events and Actions

When a setpoint status changes, i.e., a setpoint event is either asserted or de-asserted, the following happens in your device:

1. The new setpoint status is logged to the setpoint status register that can be monitored through communications from the SCADA system or from a programmable

80 Series PM172 Powermeters

Chapter 4 PAS Application Software

General Meter Setup controller in order to give an indication on the expected event.

2. The operated setpoint status is latched to the setpoint alarm latch register accessible through communications.

The register holds the last setpoint alarm status until it is explicitly cleared through communications.

3. Up to four programmable actions can be performed in sequence on setpoint status transition when a setpoint event is asserted.

Generally, setpoint actions are performed independently for each setpoint and can be repeated a number of times for the same target. The exceptions are relay operations, data logging and waveform logging that are shared for each separate target between all setpoints using an OR scheme.

A relay output is operated when one of the setpoints linked to the relay is activated and will stay in the operated state until all of these setpoints are released (except for latched relays that require a separate release command to be deactivated).

Data logging and waveform logging directed to the same file are done once for the first setpoint among those that specify the same action, guaranteeing that there will not be repeated records related to the same time.

Recording Setpoint Events

Time-tagged setpoint events can be recorded to the device Event Log if you put a corresponding action into the setpoint action list. The Event Recorder will log any setpoint transition event: both when the setpoint is operated, and when it is released. The Event Recorder will put into a log file a separate record for each active trigger caused a setpoint status transition, and a separate record for each action done on the setpoint activation (except for data logging actions that are not recorded to the Event Log).

Configuring Recorders

The PM172E and PM72EH are provided with a 1-Megabyte onboard nonvolatile memory for data, event and waveform recording.

Before using recorders, the device memory should be partitioned between log files. The device memory is fully configurable. You can define how much memory to allocate for each log file. If you want to change the factory settings, follow the guidelines in the section below.

Configuring Device Memory

The device memory can be partitioned for a total of 11 log files:

Event Log

8 Data Logs

2 Waveform Logs

To view the present device memory settings, select Memory/Log from the

Meter Setup menu, and then click on the Log Memory tab.

TOU Profile Data Log Files

Data Log #8 is configurable to store TOU daily profile log records on a daily basis.

A TOU profile log file is organized as a multi-section file that has a separate section for each TOU energy and maximum demand register. The number of sections is taken automatically from the Summary/TOU Registers setup (see

“Configuring Summary and TOU Registers”). If you selected to profile TOU

Series PM172 Powermeters 89

maximum demands along with energy registers, then the number of sections in the file will be twice the number of the allocated TOU registers.

To configure a TOU daily profile log file:

1. Configure your TOU registers and TOU schedule in the meter before allocating memory for the profile log file (see

“Configuring Summary and TOU Registers”).

2. Double click on the DATA LOG #8 partition with the left mouse button.

3. Select the TOU Daily profile file type for your file.

4. Select the number of season tariffs in your TOU schedule.

Add one additional parameter if you selected to record the

Summary (TOU total) registers as well.

5. Select the maximum number of records you want to be recorded in the file assuming that a new record will be added once a day.

6. Click OK and send your setup to the meter or save to the database.

Configuring the Waveform Recorder

Waveform log files are organized as multi-section files that store data for each recording channel in a separate section. A waveform log file stores 6 channels simultaneously: three voltage and three current channels.

A single waveform record for a channel contains 512 points of the sampled input signal. If a waveform log is configured to record more samples per event than a single record can hold, the waveform recorder stores as many records per event as required to record the entire event. All waveform records related to the event are merged in a series and have the same series number, so that they can be plotted together.

The PM172EH supports two waveform files that record waveforms at two fixed sampling rates:

• Waveform Log #1 – at 32 samples/cycle

• Waveform Log #2 – at 128 samples/cycle

To configure a waveform log file:

1. Double click on a waveform log partition with the left mouse button.

2. Select a file type for your file.

3. Select the maximum number of records you want to be recorded in the file.

The number of records in the waveform log file needed to store one waveform event (series) is defined as follows:

Series PM172 Powermeters

Number of Records per Series = Sampling Rate (Samples per Cycle) x

Number of Cycles per Event / 512

The total number of records you must allocate to store the required number of events (series) is defined as follows:

Number of Records = Number of Records per Series x Number of Series

For example, if you want to record a 64-cycle waveform sampled at a rate of 32 samples per cycle, the number of records required for one waveform series would be:

Number of Records per Series = (32 x 64)/512 = 4.

If you want to allocate space sufficient to store 20 waveform events (series), you should set up the waveform log file for 4 x 20 = 80 records.

4. Click OK, and send your setup to the meter or save to the database.

5. Click “Setup Recorder”, or click on the “Waveform

Recorder” tab.

The total number of AI, BI and BC change event points may not exceed 64. When

you change the number of the change event points in the device, all event

setpoints are set to defaults (see Configuring DNP Event Classes below).

Scaling 16-bit AI objects

Scaling 16-bit AI objects allows accommodating native 32-bit analog input readings to 16-bit object format; otherwise it may cause an over-range error if the full-range value exceeds a 16-bit point limit.

Scaling is enabled by default. It is not applied to points that are read using

32-bit AI objects.

Refer to the PM172 DNP3 Reference Guide for information on the data point scales and on a reverse conversion that should be applied to the received scaled values.

If the scaling unit is greater than 1, the counter value is reported being divided by the selected scaling unit from 10 to 1000. To get the actual value, multiply the counter reading by the scaling unit.

Configuring DNP Class 0

The most common method of getting static object information from the meter via DNP is to issue a read Class 0 request.

The PM172 allows you to configure the Class 0 response by assigning ranges of points to be polled via Class 0 requests.

To view or change the factory-set DNP Class 0 assignments, select Protocol

Setup from the Meter Setup menu and click on the DNP Class 0 Points tab.

The factory-set Class 0 point ranges are shown in the picture below. To change the factory settings and build your own Class 0 response message:

1. Select the object and variation type for a point range.

2. Specify the start point index and the number of points in the range. Refer to the PM172 DNP3 Reference Guide for available data points.

3. Repeat these steps for all point ranges you want to be included into the Class 0 response.

4. Click Send to download your setup to the meter.

Configuring DNP Event Classes

The PM172 can generate object change events for any static analog input, binary input and binary counter point when a corresponding point either exceeds a predefined threshold, or the point status changes. A total of 64 change event points are available for monitoring.

Object change events are normally polled via DNP Class 1, Class 2 or Class

3 requests. You can link any change event point to any event class upon the event priority. Refer to the PM172 DNP3 Reference Guide for more information on polling event classes via DNP.

A change event point index is normally the same as for the corresponding static object point. If you wish to use independent numeration for event

Series PM172 Powermeters

Chapter 4 PAS Application Software

Configuring Communication Protocols points, enable re-mapping event point indices via DNP Options setup (see above) so they would start with index 0.

You should define a separate event setpoint for each static object point you wish to be monitored for change events. To view or change the factory-set

DNP event setpoints, select Protocol Setup from the Meter Setup menu and click on the DNP Event Setpoints tab.

The number of event setpoints for each static object type is specified via the

DNP Options setup (see above). Notice that the device clears all event buffers and links the default set of static points to each event object type every time you change the number of points for any of the objects.

To define setpoints for selected static points:

1. Check the “Ext” box if you wish to use the extended point list.

2. Select a parameter group and then a desired parameter for each event point.

3. For AI and BC points, select a relation and an operating threshold or a deadband to be used for detecting events.

All thresholds are specified in primary units. The following relations are available:

Delta – a new event is generated when the absolute value of the difference between the last reported point value and its current value exceeds the specified deadband value;

More than (over) - a new event is generated when the point value rises over the specified threshold, and then when it returns below the threshold minus a predefined return hysteresis – applicable for AI objects;

Less than (under) - a new event is generated when the point value drops below the specified threshold, and then when it returns above the threshold plus a predefined return hysteresis – applicable for AI objects.

Viewing Recorded Files

Viewing the Device Event Log

Event log files are displayed in a tabular view. PAS loads the entire database table to a window, so that you can scroll through the entire log to view its contents.

Filtering and Sorting Events

To filter events, click on the Filter button , or click on the report window with the right mouse button and select “Filter...”. Check the causes of events you want to display, and then click OK.

Event records are normally shown in the order based on the date and time of the event appearance. To change the sorting order, click on the Sort button

, or click on the report window with the right mouse button and select

“Sort...”, check the desired sort order, and then click OK.

Linking to Waveforms and Data Records

If a setpoint triggers the Waveform or Data recorder and is programmed to

log setpoint events to the Event log (see Recording Setpoint Events ), then

PAS automatically establishes links to retrieved waveforms and data records where it finds a relationship with the event.

The event ID for which PAS finds related data is blue colored. To check a list of the event links, click on the colored event ID. Click on a list item to move to the waveform or data log record.

Selecting Primary and Secondary Units

Voltages and currents can be displayed in primary or secondary units. Click on the report window with the right mouse button, select Options, select the desired units for voltages and currents, and then click OK.

Selecting Waveform Channels

Viewing Recorded Files

To select the channels you want to view on the screen, click on the waveform window with the right mouse button, select “Channels...”, check the channels you want displayed, and then click OK.

Using the Marker Lines

Waveform and RMS panes have two blue dashed marker lines. The left marker indicates the position from where data is taken to calculate the harmonics spectrum and phasor diagrams, and as the starting position for calculating the RMS, average and peak values. The right marker indicates the end position for calculating the RMS, average and peak values. The minimum distance between the two markers is exactly one cycle.

To change the marker position, click on the button, or click on the waveform window with the right mouse button and select Set Marker, and then click on the point where you want to put the marker. You can drag both markers with the mouse, or use the right and left arrow keys on your keyboard to change the marker position. Click on the waveform pane to allow the keyboard to get your input before using the keyboard.

Delta Measurements

To measure the distance between two waveform points, click on the Delta button , then click on one point, and then click on the second point. The first reference point is still frozen until you close and reopen Delta, while the second point can be placed anywhere within the waveform line. You can measure a delta in both directions. To disable the Delta, click on the Delta button once again.

Selecting the Time Axis

The horizontal axis can be displayed either in absolute time with date and time stamps, or in milliseconds relatively to the beginning of a waveform. To change the time units, click on the waveform window with the right mouse button, select “Options...”, click on the “Axes” tab, select the desired units, and then click OK.

Viewing Phasor Diagrams

The phasor diagrams show you the relative magnitudes and angles of the three-phase voltage and current fundamental component. All angles are shown relative to the reference voltage channel.

To change the reference channel, click on the waveform window with the right mouse button, select “Options...”, click on the “Phasor” tab, check the channel you want to make a reference channel, and then click “OK”.

If you leave the Triangle box checked, PAS connects the ends of the voltage and current vectors showing you three-phase voltage and current triangles.

This is useful when analyzing voltage and current unbalances.

Phasor diagrams are calculated over one waveform cycle pointed to by the left marker line. As you move the marker, the phasor diagrams are updated reflecting the new marker position.

Viewing Symmetrical Components

PAS can calculate the symmetrical components for voltages and currents at the point indicated by the left marker line. To enable or disable the symmetrical components, click on the waveform window with the right mouse button, select “Options...”, check or uncheck the “Symmetrical components” box on the “Channels” tab, and then click OK.

Selecting Primary and Secondary Units

Voltages and currents can be displayed in primary or secondary units. Click on the waveform window with the right mouse button, select “Options...”,

Using a Zoom

Use the green arrowheads on the local toolbar to zoom in or out of the waveform graph. Every click on these buttons gives you a 100-percent horizontal or 50-percent vertical zoom. Use the magnifying glass buttons to get a proportional zoom in both directions.

When in the overlapped waveform view, you can zoom in on a selected waveform region. Click on the waveform window with the right mouse button, click 'Zoom', point onto one of the corners of the region you want to zoom in, press and hold the left mouse button, then point to another corner of the selected region and release the mouse button.

Customizing Line Colors and Styles

To change the colors or line styles, click on the waveform window with the right mouse button, select “Options...”, click on the Display tab, adjust colors and styles, and then click OK. You can also change the waveform background and gridlines color.

To change a phase, click on the window with the right mouse button, select

“Options...”, check the phase you want displayed, and then click OK.

Viewing a Frequency Plot

Click on the button to view a cycle-by-cycle voltage frequency plot.

Viewing Synchronized Waveforms

If you have a number of devices with synchronized clocks, you can view waveforms recorded at different locations in one window. PAS synchronizes the time axes for different waveforms so they could be displayed in a single plot.

To get synchronized waveforms:

1. Put the databases with waveforms into the same folder, or put the sites from which you have uploaded data to the same group in the sites tree.

2. Open a waveform you want to synchronize with other waveforms, and then click on the Multi-site View button . PAS searches for timecoordinated waveforms that have the same time span as the selected waveform.
