Indicators and Controls

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

Measurement Units

Port Activity LEDs

Navigation Buttons

Displayed Parameters

diSP

Con.Err

Chapter 3 Display Operations Data Display

Series PM172 Powermeters 33

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.

Chapter 3 Display Operations Data Display

34 Series PM172 Powermeters

• 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.

• 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.

Navigation Buttons

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.

• 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

Chapter 4 PAS Application Software Configuration Database

56 Series PM172 Powermeters

Chapter 4 PAS Application Software

Supplemental PAS software can be used for configuring the PM172 through communication ports, for retrieving real-time and recorded data, and for remote upgrading device firmware.

For information on how to install PAS on your PC, see the “PAS Getting Started” guide supplied on the installation CD.

Configuration Database

To communicate with your meters, create a separate site database for each device. All communication and configuration data for your meter is stored in this database. During configuration, store all setups to the site database so that PAS recognizes device properties regardless of whether the device is online or offline.

To create a new database for your meter:

1. Select Configuration from the Tools menu, and then click the Sites button on the right-hand side.

2. From the “Look in” box, select the directory where a new database will be stored. By default, it will be the “Sites” directory. Type a site name for your device in the “File name” box, click New, and then click OK.

3. On the Instrument Setup tab, select “PM172-N” for the PM172P and PM172E, or select “PM172EH-N” for the PM172EH, in the “Model” box. PAS automatically selects the appropriate instrument options for your meter.

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.

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

Chapter 4 PAS Application Software Configuring Communications in your Meter

Series PM172 Powermeters 63

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.

Daylight Saving Time

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.

The available options are shown in the following table.

Parameter Options Default Description

where both transitions are used.

Debounce time 1-1000 ms 10 ms The amount of time while the state

of the digital input should not

change to be recognized as a new

state. Too low debounce time could

produce multiple events on the

Chapter 4 PAS Application Software General Meter Setup

70 Series PM172 Powermeters

The debounce time is used the same for both digital inputs. If you change the debounce time for one digital input, the same debounce time is automatically assigned to the other.

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.

Chapter 4 PAS Application Software General Meter Setup

Series PM172 Powermeters 71

The available relay options are shown in the following table:

Programming Analog Inputs

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 Meter Setup menu, and then click on the Analog Inputs tab. If you are programming your device online, analog inputs are designated as not available if they are not present in the device.

The available options are described in the following table.

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.

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.

The available analog output options are described in the following table.

Chapter 4 PAS Application Software General Meter Setup

74 Series PM172 Powermeters

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.

Chapter 4 PAS Application Software General Meter Setup

Series PM172 Powermeters 75

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.

Before entering the setup dialog, ensure that you selected the correct analog current option for your expander on the Instrument Setup tab in the Tools/Configuration dialog. For scaling output parameters, see “Programming Analog Outputs” above.

Ì Analog expander outputs are not operational until you globally enable the analog

expander option in your meter through the Device Options menu.

Using Counters

The meter provides four six-digit counters that count different events.

To configure the device counters, select General Setup from the Meter Setup menu, and then click on the Pulse/Event Counters tab.

Each counter is independently linked to any digital input and count input pulses with a programmable scale factor. Each counter can also be incremented in response to any internal or external event, checked and cleared through the Control Setpoints.

The following table lists available options.

contents

You can preset a counter to a desired value or clear it through this dialog without affecting the counter setup. Check the Online button on the PAS toolbar before entering the setup dialog, type in the desired value into the 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.

Chapter 4 PAS Application Software General Meter Setup

78 Series PM172 Powermeters

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.

The available setpoint options are described in the following table.

Series PM172 Powermeters 79

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

Chapter 4 PAS Application Software General Meter Setup

80 Series PM172 Powermeters

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.

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

Chapter 4 PAS Application Software General Meter Setup

Series PM172 Powermeters 81

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).

Chapter 4 PAS Application Software Configuring Summary Energy and TOU Registers

82 Series PM172 Powermeters

Configuring Summary Energy and TOU Registers

The PM172E and PM172EH provide 8 total (summary) energy and 8 concurrent tariff energy and maximum demand registers that can be linked to any internal energy source or to any external pulse source that delivers pulses through the device digital inputs.

The meter tariff structure supports 8 different tariffs using an arbitrary tariff schedule. A total of 4 types of days and 4 seasons are supported with up to eight tariff changes per day.

The meter can provide automatic daily profile recording for total and tariff energy and maximum demand registers.

By default, the billing registers in your meter and the tariff system are not operational. To activate the summary/tariff registers or to change the profile for the first billing register:

1. Link the billing registers to the respective energy sources, and then configure the options for these registers like whether the only totalization or both total and tariff registers would be used, and whether daily profiling should be enabled for the energy usage and maximum demand registers.

2. Configure the daily tariff schedule using the TOU daily profiles for all types of days and seasons.

3. Configure the season tariff schedule using the TOU calendar.

Setting up Total and Tariff Registers

To configure the device total (summary) and TOU registers, select Energy/TOU from the Meter Setup menu.

are no limitations on how to define your schedule. The meter is able to automatically recognize your settings and to select a proper daily tariff schedule for any day within a year.

The above picture gives you an example of a single-season tariff schedule configured for weekends and the designated U.S.A. holidays.

To configure your season tariff schedule:

1. In the “Season” box, select the season, and in the “Day Type” box, select a day type for this calendar entry.

2. Select the time interval when this daily tariff schedule is effective, based on the start and the end weekdays and, for a multi-season schedule, on the start and the end month for the selected season. It does not matter which order of weekdays or months you select: the meter can recognize the correct order by itself.

3. For exception days like designated holidays, select a specific day either by specifying a day and month, or by selecting a month, a week and a weekday within the month.

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”). I f you selected to profile TO U

Chapter 4 PAS Application Software Configuring Recorders

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:

Chapter 4 PAS Application Software Configuring Recorders

Series PM172 Powermeters 91

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.

Configuring Communication Protocols

This section describes how to customize protocol options for use with your application software.

Configuring Modbus

Modbus Point Mapping

The PM172 provides 120 user assignable registers in the address range of 0 to 119. You can re-map any register available in the meter to any assignable register so that Modbus registers that reside at different locations may be simply accessed using a single request by re-mapping them to adjacent addresses.

Initially these registers are reserved and none of them points to an actual data register. To build your own Modbus register map:

1. Select Protocol Setup from the Meter Setup menu and click on the Modbus Registers tab.

2. Click on the Default button to cause the assignable registers to reference the actual default meter register 6656 (0 through 119 are not allowable register addresses for re-mapping).

3. Type in the actual addresses you want to read from or write to via the assignable registers. Refer to the PM172 Modbus Reference Guide for a list of the available registers. Notice that 32-bit Modbus registers should always start at an even register address.

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

The Select Before Operate command causes the device to start a timer. The following Operate command must be sent before the specified timeout value expires.

The device requests time synchronization by bit 4 in the first octet of the internal indication word being set to 1 when the time interval specified by the Time Sync Period elapses. The master should synchronize the time in the device by sending the Time and Date object to clear this bit. The device does not send time synchronization requests if the Time Sync Period is set to 0.

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.

Scaling 16-bit Binary Counters

Scaling 16-bit Binary Counters allows changing a counter unit in powers of 10 to accommodate a 32-bit counter value to 16-bit BC object format.

Chapter 4 PAS Application Software Configuring Communication Protocols

96 Series PM172 Powermeters

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

Chapter 4 PAS Application Software Configuring Communication Protocols

Series PM172 Powermeters 97

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.

Chapter 4 PAS Application Software Configuring Communication Protocols

98 Series PM172 Powermeters

A hysteresis for the return threshold is 0.05 Hz for frequency and 2% of the operating threshold for all other points.

4. Check the “Ev On” box for the points you wish to be included into event poll reports.

5. In the “Ev Class” box, select the event poll class for the change event points.

6. Repeat these steps for all points you want to be monitored for events.
