Three-Phase Power Measurement
This introduction to three-phase power and power measurement is intended to provide only a brief overview of the subject. The professional meter engineer or meter technician should refer to more advanced documents such as the EEI Handbook for Electricity
Metering and the application standards for more in-depth and technical coverage of the subject.

CHAPTER 1: THREE-PHASE POWER MEASUREMENT
1.1
Three-Phase System Configurations
Three-phase power is most commonly used in situations where large amounts of power will be used because it is a more effective way to transmit the power and because it provides a smoother delivery of power to the end load. There are two commonly used connections for three-phase power, a wye connection or a delta connection. Each connection has several different manifestatWye Connection
The wye connection is so called because when you look at the phase relationships and the winding relationships between the phases it looks like a Y. Figure 1.1 depicts the winding relationships for a wye-connected service. In a wye service the neutral (or center point of the wye) is typically grounded. This leads to common voltages of 208/120 and 480/277
(where the first number represents the phase-to-phase voltage and the second number represents the phase-to-ground voltage).

CHAPTER 1: THREE-PHASE POWER MEASUREMENT
The three voltages are separated by 120 o
electrically. Under balanced load conditions the currents are also separated by 120 o
. However, unbalanced loads and other conditions can cause the currents to depart from the ideal 120 o
separation. Three-phase voltages and currents are usually represented with a phasor diagram. A phasor diagram for the typical connected voltages and currents is shown in Figure 1.2.

The phasor diagram shows the 120 o
angular separation between the phase voltages. The phase-to-phase voltage in a balanced three-phase wye system is 1.732 times the phaseto-neutral voltage. The center point of the wye is tied together and is typically grounded.
Table 1.1 shows the common voltages used in the United States for wye-connected systems.

Usually a wye-connected service will have four wires: three wires for the phases and one for the neutral. The three-phase wires connect to the three phases (as shown in Figure 1.1).
The neutral wire is typically tied to the ground or center point of the wye (refer to Figure
1.1).
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE 1–3
CHAPTER 1: THREE-PHASE POWER MEASUREMENT
In many industrial applications the facility will be fed with a four-wire wye service but only three wires will be run to individual loads. The load is then often referred to as a deltaconnected load but the service to the facility is still a wye service; it contains four wires if you trace the circuit back to its source (usually a transformer). In this type of connection the phase to ground voltage will be the phase-to-ground voltage indicated in Table 1, even though a neutral or ground wire is not physically present at the load. The transformer is the best place to determine the circuit connection type because this is a location where the voltage reference to ground can be conclusively identified.
1.1.1
Delta Connection
Delta-connected services may be fed with either three wires or four wires. In a three-phase delta service the load windings are connected from phase-to-phase rather than from phase-to-ground. Figure 1.3 shows the physical load connections for a delta service.

In this example of a delta service, three wires will transmit the power to the load. In a true delta service, the phase-to-ground voltage will usually not be balanced because the ground is not at the center of the delta.
Figure 1.4 shows the phasor relationships between voltage and current on a three-phase delta circuit.
In many delta services, one corner of the delta is grounded. This means the phase to ground voltage will be zero for one phase and will be full phase-to-phase voltage for the other two phases. This is done for protective purposes.

In this connection the center point of one winding is grounded. On a 120/240 volt, fourwire, grounded delta service the phase-to-ground voltage would be 120 volts on two phases and 208 volts on the third phase.

CHAPTER 1: THREE-PHASE POWER MEASUREMENT
1.1.2 Blondell’s Theorem and Three Phase Measurement
In 1893 an engineer and mathematician named Andre E. Blondell set forth the first scientific basis for polyphase metering. His theorem states:
If energy is supplied to any system of conductors through N wires, the total power in the system is given by the algebraic sum of the readings of N wattmeters so arranged that each of the N wires contains one current coil, the corresponding potential coil being connected between that wire and some common point. If this common point is on one of the N wires, the measurement may be made by the use of N-1 Wattmeters.
The theorem may be stated more simply, in modern language:
In a system of N conductors, N-1 meter elements will measure the power or energy taken provided that all the potential coils have a common tie to the conductor in which there is no current coil.
Three-phase power measurement is accomplished by measuring the three individual phases and adding them together to obtain the total three phase value. In older analog meters, this measurement was accomplished using up to three separate elements. Each element combined the single-phase voltage and current to produce a torque on the meter disk. All three elements were arranged around the disk so that the disk was subjected to the combined torque of the three elements. As a result the disk would turn at a higher speed and register power supplied by each of the three wires.
According to Blondell's Theorem, it was possible to reduce the number of elements under certain conditions. For example, a three-phase, three-wire delta system could be correctly measured with two elements (two potential coils and two current coils) if the potential coils were connected between the three phases with one phase in common.
In a three-phase, four-wire wye system it is necessary to use three elements. Three voltage coils are connected between the three phases and the common neutral conductor. A current coil is required in each of the three phases.
In modern digital meters, Blondell's Theorem is still applied to obtain proper metering. The difference in modern meters is that the digital meter measures each phase voltage and current and calculates the single-phase power for each phase. The meter then sums the three phase powers to a single three-phase reading.
Some digital meters calculate the individual phase power values one phase at a time. This means the meter samples the voltage and current on one phase and calculates a power value. Then it samples the second phase and calculates the power for the second phase.
Finally, it samples the third phase and calculates that phase power. After sampling all three phases, the meter combines the three readings to create the equivalent three-phase power value. Using mathematical averaging techniques, this method can derive a quite accurate measurement of three-phase power.
More advanced meters actually sample all three phases of voltage and current simultaneously and calculate the individual phase and three-phase power values. The advantage of simultaneous sampling is the reduction of error introduced due to the difference in time when the samples were taken.

FIGURE 1–5: Figure 1.6: Three-Phase Wye Load Illustrating Kirchhoff’s Law and Blondell’s Theorem
Blondell's Theorem is a derivation that results from Kirchhoff's Law. Kirchhoff's Law states that the sum of the currents into a node is zero. Another way of stating the same thing is that the current into a node (connection point) must equal the current out of the node. The law can be applied to measuring three-phase loads. Figure 1.6 shows a typical connection of a three-phase load applied to a three-phase, four-wire service. Krichhoff's Law holds that the sum of currents A, B, C and N must equal zero or that the sum of currents into
Node "n" must equal zero.
If we measure the currents in wires A, B and C, we then know the current in wire N by
Kirchhoff's Law and it is not necessary to measure it. This fact leads us to the conclusion of
Blondell's Theorem- that we only need to measure the power in three of the four wires if they are connected by a common node. In the circuit of Figure 1.6 we must measure the power flow in three wires. This will require three voltage coils and three current coils (a three-element meter). Similar figures and conclusions could be reached for other circuit configurations involving Delta-connected loads.

CHAPTER 1: THREE-PHASE POWER MEASUREMENT
1.2
Power, Energy and Demand
It is quite common to exchange power, energy and demand without differentiating between the three. Because this practice can lead to confusion, the differences between these three measurements will be discussed.
Power is an instantaneous reading. The power reading provided by a meter is the present flow of watts. Power is measured immediately just like current. In many digital meters, the power value is actually measured and calculated over a one second interval because it takes some amount of time to calculate the RMS values of voltage and current. But this time interval is kept small to preserve the instantaneous nature of power.
Energy is always based on some time increment; it is the integration of power over a defined time increment. Energy is an important value because almost all electric bills are based, in part, on the amount of energy used.
Typically, electrical energy is measured in units of kilowatt-hours (kWh). A kilowatt-hour represents a constant load of one thousand watts (one kilowatt) for one hour. Stated another way, if the power delivered (instantaneous watts) is measured as 1,000 watts and the load was served for a one hour time interval then the load would have absorbed one kilowatt-hour of energy. A different load may have a constant power requirement of 4,000 watts. If the load were served for one hour it would absorb four kWh. If the load were served for 15 minutes it would absorb ¼ of that total or one kWh.
Figure 1.7 shows a graph of power and the resulting energy that would be transmitted as a result of the illustrated power values. For this illustration, it is assumed that the power level is held constant for each minute when a measurement is taken. Each bar in the graph will represent the power load for the one-minute increment of time. In real life the power value moves almost constantly.
The data from Figure 1.7 is reproduced in Table 2 to illustrate the calculation of energy.
Since the time increment of the measurement is one minute and since we specified that the load is constant over that minute, we can convert the power reading to an equivalent consumed energy reading by multiplying the power reading times 1/60 (converting the time base from minutes to hours).

MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE 1–9
CHAPTER 1: THREE-PHASE POWER MEASUREMENT
Demand is also a time-based value. The demand is the average rate of energy use over time. The actual label for demand is kilowatt-hours/hour but this is normally reduced to kilowatts. This makes it easy to confuse demand with power, but demand is not an instantaneous value. To calculate demand it is necessary to accumulate the energy readings (as illustrated in Figure 1.7) and adjust the energy reading to an hourly value that constitutes the demand.
In the example, the accumulated energy is 14.92 kWh. But this measurement was made over a 15-minute interval. To convert the reading to a demand value, it must be normalized to a 60-minute interval. If the pattern were repeated for an additional three 15minute intervals the total energy would be four times the measured value or 59.68 kWh.
The same process is applied to calculate the 15-minute demand value. The demand value associated with the example load is 59.68 kWh/hr or 59.68 kWd. Note that the peak instantaneous value of power is 80 kW,, significantly more than the demand value.
Figure 1.8 shows another example of energy and demand. In this case, each bar represents the energy consumed in a 15-minute interval. The energy use in each interval typically falls between 50 and 70 kWh. However, during two intervals the energy rises sharply and peaks at 100 kWh in interval number 7. This peak of usage will result in setting a high demand reading. For each interval shown the demand value would be four times the indicated energy reading. So interval 1 would have an associated demand of 240 kWh/ hr. Interval 7 will have a demand value of 400 kWh/hr. In the data shown, this is the peak demand value and would be the number that would set the demand charge on the utility bill.

CHAPTER 1: THREE-PHASE POWER MEASUREMENT
1.3
Reactive Energy and Power Factor
The real power and energy measurements discussed in the previous section relate to the quantities that are most used in electrical systems. But it is often not sufficient to only measure real power and energy. Reactive power is a critical component of the total power picture because almost all real-life applications have an impact on reactive power.
Reactive power and power factor concepts relate to both load and generation applications. However, this discussion will be limited to analysis of reactive power and power factor as they relate to loads. To simplify the discussion, generation will not be considered.
Real power (and energy) is the component of power that is the combination of the voltage and the value of corresponding current that is directly in phase with the voltage. However, in actual practice the total current is almost never in phase with the voltage. Since the current is not in phase with the voltage, it is necessary to consider both the inphase component and the component that is at quadrature (angularly rotated 90 o
or perpendicular) to the voltage. Figure 1.9 shows a single-phase voltage and current and breaks the current into its in-phase and quadrature components.

) are combined to calculate the reactive
The quadrature current may be lagging the voltage (as shown in Figure 1.9) or it may lead the voltage. When the quadrature current lags the voltage the load is requiring both real power (watts) and reactive power (VARs). When the quadrature current leads the voltage the load is requiring real power (watts) but is delivering reactive power (VARs) back into the system; that is VARs are flowing in the opposite direction of the real power flow.
Reactive power (VARs) is required in all power systems. Any equipment that uses magnetization to operate requires VARs. Usually the magnitude of VARs is relatively low compared to the real power quantities. Utilities have an interest in maintaining VAR requirements at the customer to a low value in order to maximize the return on plant invested to deliver energy. When lines are carrying VARs, they cannot carry as many watts.
So keeping the VAR content low allows a line to carry its full capacity of watts. In order to encourage customers to keep VAR requirements low, some utilities impose a penalty if the
VAR content of the load rises above a specified value.
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE 1–11
CHAPTER 1: THREE-PHASE POWER MEASUREMENT
A common method of measuring reactive power requirements is power factor. Power factor can be defined in two different ways. The more common method of calculating power factor is the ratio of the real power to the apparent power. This relationship is expressed in the following formula:
Total PF = real power / apparent power = watts/VA
This formula calculates a power factor quantity known as Total Power Factor. It is called
Total PF because it is based on the ratios of the power delivered. The delivered power quantities will include the impacts of any existing harmonic content. If the voltage or current includes high levels of harmonic distortion the power values will be affected. By calculating power factor from the power values, the power factor will include the impact of harmonic distortion. In many cases this is the preferred method of calculation because the entire impact of the actual voltage and current are included.
A second type of power factor is Displacement Power Factor. Displacement PF is based on the angular relationship between the voltage and current. Displacement power factor does not consider the magnitudes of voltage, current or power. It is solely based on the phase angle differences. As a result, it does not include the impact of harmonic distortion.
Displacement power factor is calculated using the following equation:
Displacement PF = cos
θ where
θ is the angle between the voltage and the current (see Fig. 1.9).
In applications where the voltage and current are not distorted, the Total Power Factor will equal the Displacement Power Factor. But if harmonic distortion is present, the two power factors will not be equal.

Harmonic Distortion
Harmonic distortion is primarily the result of high concentrations of non-linear loads.
Devices such as computer power supplies, variable speed drives and fluorescent light ballasts make current demands that do not match the sinusoidal waveform of AC electricity. As a result, the current waveform feeding these loads is periodic but not sinusoidal. Figure 1.10 shows a normal, sinusoidal current waveform. This example has no distortion.

CHAPTER 1: THREE-PHASE POWER MEASUREMENT
The distortion observed in Figure 1.11 can be modeled as the sum of several sinusoidal waveforms of frequencies that are multiples of the fundamental 60 Hz frequency. This modeling is performed by mathematically disassembling the distorted waveform into a collection of higher frequency waveforms.
These higher frequency waveforms are referred to as harmonics. Figure 1.12 shows the content of the harmonic frequencies that make up the distortion portion of the waveform in Figure 1.11.

FIGURE 1–11: Figure 1.12: Waveforms of the Harmonics
The waveforms shown in Figure 1.12 are not smoothed but do provide an indication of the impact of combining multiple harmonic frequencies together.
When harmonics are present it is important to remember that these quantities are operating at higher frequencies. Therefore, they do not always respond in the same manner as 60 Hz values.
Inductive and capacitive impedance are present in all power systems. We are accustomed to thinking about these impedances as they perform at 60 Hz. However, these impedances are subject to frequency variation.
X
L
= j ωL and
X
C
= 1/j ωC
At 60 Hz, ω = 377; but at 300 Hz (5th harmonic) ω = 1,885. As frequency changes impedance changes and system impedance characteristics that are normal at 60 Hz may behave entirely differently in the presence of higher order harmonic waveforms.
Traditionally, the most common harmonics have been the low order, odd frequencies, such as the 3rd, 5th, 7th, and 9th. However newer, new-linear loads are introducing significant quantities of higher order harmonics.
Since much voltage monitoring and almost all current monitoring is performed using instrument transformers, the higher order harmonics are often not visible. Instrument transformers are designed to pass 60 Hz quantities with high accuracy. These devices, when designed for accuracy at low frequency, do not pass high frequencies with high
1–14 MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE
CHAPTER 1: THREE-PHASE POWER MEASUREMENT accuracy; at frequencies above about 1200 Hz they pass almost no information. So when instrument transformers are used, they effectively filter out higher frequency harmonic distortion making it impossible to see.
However, when monitors can be connected directly to the measured circuit (such as direct connection to a 480 volt bus) the user may often see higher order harmonic distortion. An important rule in any harmonics study is to evaluate the type of equipment and connections before drawing a conclusion. Not being able to see harmonic distortion is not the same as not having harmonic distortion.
It is common in advanced meters to perform a function commonly referred to as waveform capture. Waveform capture is the ability of a meter to capture a present picture of the voltage or current waveform for viewing and harmonic analysis. Typically a waveform capture will be one or two cycles in duration and can be viewed as the actual waveform, as a spectral view of the harmonic content, or a tabular view showing the magnitude and phase shift of each harmonic value. Data collected with waveform capture is typically not saved to memory. Waveform capture is a real-time data collection event.
Waveform capture should not be confused with waveform recording that is used to record multiple cycles of all voltage and current waveforms in response to a transient condition.

Power Quality
Power quality can mean several different things. The terms "power quality" and "power quality problem" have been applied to all types of conditions. A simple definition of "power quality problem" is any voltage, current or frequency deviation that results in misoperation or failure of customer equipment or systems. The causes of power quality problems vary widely and may originate in the customer equipment, in an adjacent customer facility or with the utility.
In his book Power Quality Primer, Barry Kennedy provided information on different types of power quality problems. Some of that information is summarized in Table 1.3.

It is often assumed that power quality problems originate with the utility. While it is true that may power quality problems can originate with the utility system, many problems originate with customer equipment. Customer-caused problems may manifest themselves inside the customer location or they may be transported by the utility system to another adjacent customer. Often, equipment that is sensitive to power quality problems may in fact also be the cause of the problem.
If a power quality problem is suspected, it is generally wise to consult a power quality professional for assistance in defining the cause and possible solutions to the problem.

EPM7000 Meter Overview
The EPM7000 meter is a multifunction, data logging, power and energy meter with waveform recording capability, designed to be used in electrical substations, panel boards, as a power meter for OEM equipment, and as a primary revenue meter, due to its high performance measurement capability. The unit provides multifunction measurement of all electrical parameters and makes the data available in multiple formats via display, communication systems, and analog retransmits. The unit also has data logging and load profiling to provide historical data analysis, and waveform recording that allows for enhanced power quality analysis.
The EPM7000 meter offers up to 4 MegaBytes of flash memory. The unit provides you with up to seven logs: three historic logs, a log of limit alarms, a log of I/O changes, a waveform log, and a sequence of events log. (See NOTE on flash memory on page 2-6.)
The purposes of these features include historical load profiling, voltage analysis, and recording power factor distribution. The EPM7000 meter’s real-time clock allows all events to be time-stamped.
Optional 100BaseT Ethernet capability is available for the meter. When it is equipped with an Ethernet card, the meter’s real-time clock can be synchronized with an outside Network Time Protocol (NTP) server (see the GE Communicator EXT USer Manual for instructions on using this feature.) A EPM7000 meter with an Ethernet card also becomes a
Web server. See Chapter 8 for more information on this feature.
The EPM7000 meter is designed with advanced measurement capabilities, allowing it to achieve high performance accuracy. It is specified as a 0.2% class energy meter for billing applications as well as a highly accurate panel indication meter.
The EPM7000 meter provides additional capabilities, including standard RS485, Modbus and DNP 3.0 Protocols, an IrDA Port for remote interrogation, and Option cards that can be added at any time.

Voltage and Current Inputs
Universal Voltage Inputs
Voltage Inputs allow measurement up to Nominal 480VAC (Phase to Reference) and
600VAC (Phase to Phase). This insures proper meter safety when wiring directly to high voltage systems. One unit will perform to specification on 69 Volt, 120 Volt, 230 Volt, 277
Volt, and 347 Volt power systems.
Higher voltages require the use of potential transformers (PTs).
Current Inputs
The unit supports a 5 Amp or a 1 Amp secondary for current measurements.
The secondary current must be specified and ordered with the meter.
The EPM7000 meter’s Current Inputs use a unique dual input method:
2–2 MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE
CHAPTER 2: METER OVERVIEW AND SPECIFICATIONS
Method 1: CT Pass Through
The CT passes directly through the meter without any physical termination on the meter.
This insures that the meter cannot be a point of failure on the CT circuit. This is preferable for utility users when sharing relay class CTs. No Burden is added to the secondary CT circuit.
Method 2: Current “Gills”
This unit additionally provides ultra-rugged Termination Pass Through Bars that allow CT leads to be terminated on the meter. This, too, eliminates any possible point of failure at the meter. This is a preferred technique for insuring that relay class CT integrity is not compromised (the CT will not open in a fault condition).

Utility Peak Demand
The EPM7000 meter provides user-configured Block (Fixed) Window or Rolling Window
Demand modes. This feature enables you to set up a customized Demand profile. Block
Window Demand mode records the average demand for time intervals that you define
(usually 5, 15 or 30 minutes). Rolling Window Demand mode functions like multiple, overlapping Block Window Demands. You define the subintervals at which an average of demand is calculated. An example of Rolling Window Demand mode would be a 15minute Demand block using 5-minute subintervals, thus providing a new demand reading every 5 minutes, based on the last 15 minutes.
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE 2–5
CHAPTER 2: METER OVERVIEW AND SPECIFICATIONS
Utility Demand Features can be used to calculate Watt, VAR, VA and PF readings. Voltage provides an Instantaneous Max and Min reading which displays the highest surge and lowest sag seen by the meter. All other parameters offer Max and Min capability over the user-selectable averaging period.

Considerations When Installing Meters
Installation of the EPM7000 meter must be performed by only qualified personnel who follow standard safety precautions during all procedures. Those personnel should have appropriate training and experience with high voltage devices.
Appropriate safety gloves, safety glasses and protective clothing is recommended.
During normal operation of the EPM7000 meter, dangerous voltages flow through many parts of the meter, including: Terminals and any connected CTs (Current
Transformers) and PTs (Potential Transformers), all I/O Modules (Inputs and Outputs) and their circuits. All Primary and Secondary circuits can, at times, produce lethal voltages and currents. Avoid contact with any current-carrying surfaces.
Do not use the meter or any I/O Output Device for primary protection or in an energylimiting capacity. The meter can only be used as secondary protection. Do not use the meter for applications where failure of the meter may cause harm or death. Do not use the meter for any application where there may be a risk of fire.
All meter terminals should be inaccessible after installation.
Do not apply more than the maximum voltage the meter or any attached device can withstand. Refer to meter and/or device labels and to the Specifications for all devices before applying voltages. Do not HIPOT/Dielectric test any Outputs, Inputs or
Communications terminals.
GE Multilin recommends the use of Shorting Blocks and Fuses for voltage leads and power supply to prevent hazardous voltage conditions or damage to CTs, if the meter needs to be removed from service. CT grounding is optional.
• If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• There is no required preventive maintenance or inspection necessary for safety. however, any repair or maintenance should be performed by the factory.

CT Leads Terminated to Meter
The EPM7000 meter is designed to have Current Inputs wired in one of three ways.
Diagram 4.1 shows the most typical connection where CT Leads are terminated to the meter at the Current Gills. This connection uses Nickel-Plated Brass Studs (Current
Gills) with screws at each end. This connection allows the CT wires to be terminated using either an “O” or a “U” lug. Tighten the screws with a #2 Phillips screwdriver. The maximum installation torque is 1 Newton-Meter.
Other current connections are shown in Figures 4.2 and 4.3. Voltage and RS485/KYZ
Connection is shown in Figure 4.4.

EPM7000 Meter Communication
The EPM7000 meter provides two independent Communication Ports. The first port, COM
1, is an Optical IrDA Port. The second port, COM 2, provides RS485 communication speaking Modbus ASCII, Modbus RTU, and DNP 3.0 protocols. Additionally, the EPM7000 meter has two optional communication cards: the Fiber Optic Communication Card and the 10/100BaseT Ethernet Communication Card. See Chapter 7 for more information on these options.
5.1.1
IrDA Port (COM 1)
The EPM7000 meter’s COM 1 IrDA Port is on the face of the meter. The IrDA Port allows the unit to be read and programmed without the need of a communication cable. Just point at the meter with an IrDA-equipped laptop PC to configure it.
• Settings for COM 1 (IrDA Port) are configured using GE Communicator EXT software.
• This port only communicates via Modbus ASCII Protocol.
• Refer to Appendix D for instructions on using the USB to IrDA Adapter.
5.1.2
RS485 / KYZ Output (COM 2)
COM 2 provides a combination RS485 and an Energy Pulse Output (KYZ pulse).
See Chapter 2, Section 2.2 for the KYZ Output Specifications; see Chapter 6, Section 6.4 for
Pulse Constants.

FIGURE 5–1: EPM7000 Meter Back with RS485 Communication Installation
RS485 allows you to connect one or multiple EPM7000 meters to a PC or other device, at either a local or remote site. All RS485 connections are viable for up to 4000 feet (1219.20 meters).
FIGURE 5–2: EPM7000 Meter Connected to a PC via RS485 bus
As shown in Figure 5.2, to connect a EPM7000 meter to a PC, you need to use an RS485 to
RS232 converter.

FIGURE 5–3: 2-wire RS485 Connection
For All RS485 Connections:
• Use a shielded twisted pair cable and ground the shield, preferably at one location only.
• Establish point-to-point configurations for each device on a RS485 bus: connect (+) terminals to (+) terminals; connect (-) terminals to (-) terminals.
• You may connect up to 31 meters on a single bus using RS485. Before assembling the bus, each meter must have a unique address: refer to Chapter 5 of the GE
Communicator EXT 3.0 User’s Manual for instructions.
• Protect cables from sources of electrical noise.
• Avoid both “Star” and “Tee” connections (see Figure 5.5).
• No more than two cables should be connected at any one point on an RS485 network, whether the connections are for devices, converters, or terminal strips.
• Include all segments when calculating the total cable length of a network. If you are not using an RS485 repeater, the maximum length for cable connecting all devices is 4000 feet (1219.20 meters).
• Connect shield to RS485 Master and individual devices as shown in Figure 5.4. You may also connect the shield to earth-ground at one point.
• Termination Resistors (RT) may be needed on both ends for longer length transmission lines. However, since the meter has some level of termination internally, Termination Resistors may not be needed. When they are used, the value of the Termination Resistors is determined by the electrical parameters of the cable.

Performing Watt-Hour Accuracy Testing (Verification)
To be certified for revenue metering, power providers and utility companies must verify that the billing energy meter performs to the stated accuracy. To confirm the meter’s performance and calibration, power providers use field test standards to ensure that the unit’s energy measurements are correct. Since the EPM7000 meter is a traceable revenue meter, it contains a utility grade test pulse that can be used to gate an accuracy standard.
This is an essential feature required of all billing grade meters.
• Refer to Figure 6.5 for an example of how this process works.
• Refer to Table 6.1 for the Wh/Pulse Constants for Accuracy Testing.

Formula Explanation:
C4E11DB9 (hex): 11000100 11100001 00011101 10111001 (binary)
The sign of the mantissa (and therefore the number) is 1, which represents a negative value.
The Exponent is 10001001 (binary) or 137 decimal.
The Exponent is a value in excess 127. So, the Exponent value is 10.
The Mantissa is 11000010001110110111001 binary.
With the implied leading 1, the Mantissa is (1).611DB9 (hex).
The Floating Point Representation is therefore -1.75871956 times 2 to the 10.
Decimal equivalent: -1800.929
• Exponent = the whole number before the decimal point.
• Mantissa = the positive fraction after the decimal point.

Retrieving Logs Using the EPM7000 Meter's Modbus Map
This section describes the log interface system of the EPM7000 meter from a programming point of view. It is intended for Programmers implementing independent drivers for Log
Retrieval from the meter. It describes the meaning of the meter's Modbus Registers related to Log Retrieval and Conversion, and details the procedure for retrieving a log's records.
• All references assume the use of Modbus function codes 0x03, 0x06, and 0x10, where each register is a 2 byte MSB (Most Significant Byte) word, except where otherwise noted.
• The carat symbol (^) notation is used to indicate mathematical "power." For example,
2^8 means 28; which is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2, which equals 256.

B.5.2 EPM7000 Meter Logs
The EPM7000 meter has 6 logs: System Event, Alarm (Limits), 3 Historical, and I/O
Change. Each log is described below.
1.
System Event (0): The System Event log is used to store events which happen in, and to, the meter. Events include Startup, Reset Commands, Log Retrievals, etc. The System Event Log Record takes 20 bytes, 14 bytes of which are available when the log is retrieved.

B.5.3 Block Definitions
This section describes the Modbus Registers involved in retrieving and interpreting a
EPM7000 Meter Log. Other sections refer to certain 'values' contained in this section. See the corresponding value in this section for details.
• “Register” is the Modbus Register Address in 0-based Hexadecimal notation. To convert it to 1-based decimal notation, convert from hex16 to decimal10 and add 1.
For example: 0x03E7 = 1000.
• “Size” is the number of Modbus Registers (2 byte) in a block of data.
Historical Log Programmable Settings:
The Historical Logs are programmed using a list of Modbus Registers that will be copied into the Historical Log record. In other words, Historical Log uses a direct copy of the
Modbus Registers to control what is recorded at the time of record capture.
To supplement this, the programmable settings for the Historical Logs contain a list of descriptors, which group registers into items. Each item descriptor lists the data type of the item, and the number of bytes for that item. By combining these two lists, the Historical
Log record can be interpreted.
For example: Registers 0x03E7 and 0x03E8 are programmed to be recorded by the historical log. The matching descriptor gives the data type as float, and the size as 4 bytes.
These registers program the log to record "Primary Readings Volts A-N."
Historical Log Blocks:
Start Register: 0x7917 (Historical Log 1)
0x79D7 (Historical Log 2)
Block Size:
0x7A97 (Historical Log 3)
192 registers per log (384 bytes)
The Historical Log programmable settings are comprised of 3 blocks, one for each log.
Each is identical to the others, so only Historical Log 1 is described here. All register addresses in this section are given as the Historical Log 1 address (0x7917).
Each Historical Log Block is composed of 3 sections: The header, the list of registers to log, and the list of item descriptors.

• # Registers: The number of registers to log in the record. The size of the record in memory is [12 + (# Registers x 2)]. The size during normal log retrieval is [6 + (#
Registers x 2)]. If this value is 0, the log is disabled. Valid values are {0-117}.
• # Sectors: The number of Flash Sectors allocated to this log. Each sector is 64kb, minus a sector header of 20 bytes. 15 sectors are available for allocation between
Historical Logs 1, 2, and 3. The sum of all Historical Logs may be less than 15. If this value is 0, the log is disabled. Valid values are {0-15}.
• Interval: The interval at which the Historical Log's Records are captured. This value is an enumeration:

End of Interval (EOI) Pulse*
* Setting the interval to EOI causes a record to be logged whenever an EOI pulse event is generated. This is most commonly used in conjunction with the Digital I/O Option Cards.
The interval between records will not be even (fixed), and thus should not be used with programs that expect a fixed interval.
Register List:
Registers:
Size:
0x7919 - 0x798D
1 register per list item, 117 list items
The Register List controls what Modbus Registers are recorded in each record of the
Historical Log. Since many items, such as Voltage, Energy, etc., take up more than 1 register, multiple registers need to be listed to record those items.
For example: Registers 0x03E7 and 0x03E8 are programmed to be recorded by the historical log. These registers program the log to record "Primary Readings Volts A-N."
• Each unused register item should be set to 0x0000 or 0xFFFF to indicate that it should be ignored.
• The actual size of the record, and the number of items in the register list which are used, is determined by the # registers in the header.
• Each register item is the Modbus Address in the range of 0x0000 to 0xFFFF.

Item Descriptor List:
Registers:

1 byte per item, 117 bytes (59 registers)
While the Register List describes what to log, the Item Descriptor List describes how to interpret that information. Each descriptor describes a group of register items, and what they mean.
Each descriptor is composed of 2 parts:
• Type: The data type of this descriptor, such as signed integer, IEEE floating point, etc. This is the high nibble of the descriptor byte, with a value in the range of 0-14.
If this value is 0xFF, the descriptor should be ignored.

15 Disabled: used as end list marker.
• Size: The size in bytes of the item described. This number is used to determine the pairing of descriptors with register items.
For example: If the first descriptor is 4 bytes, and the second descriptor is 2 bytes, then the first 2 register items belong to the 1st descriptor, and the 3rd register item belongs to the
2nd descriptor.
As can be seen from the example, above, there is not a 1-to-1 relation between the register list and the descriptor list. A single descriptor may refer to multiple register items.
Register Items

The sum of all descriptor sizes must equal the number of bytes in the data portion of the

Max Records when the log has filled. This value will be set to 1 when the log is reset. The data type is an unsigned integer from 1 to 2^32.
The first record in every log before it has rolled over is a "dummy" record, filled with all
0xFF's. When the log is filled and rolls over, this record is overwritten.

• Image [2]: The full record, as it is stored in memory. Contains a 2-byte checksum, 4-byte sequence number, 6-byte timestamp, and then N data bytes for the record data.
• Records Per Window: The number of records that fit evenly into a window. This value is set-able, as less than a full window may be used. This number tells the retrieving program how many records to expect to find in the window.
(RecPerWindow x RecSize) = #bytes used in the window.
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE
APPENDIX B: MODBUS MAP AND RETRIEVING LOGS
This value should be ((123 x 2) \ recSize), rounded down.
For example, with a record size of 30, the RecPerWindow = ((123 x 2) \ 30) = 8.2 ~= 8
• Number of Repeats: Specifies the number of repeats to use for the Modbus
Function Code 0x23 (35). Since the meter must pre-build the response to each log window request, this value must be set once, and each request must use the same repeat count. Upon reading the last register in the specified window, the record index will increment by the number of repeats, if auto-increment is enabled.

Log Retrieval Window Block:
The Log Retrieval Window block is used to program the data you want to retrieve from the log. It also provides the interface used to retrieve that data.
Registers: 0xC351 - 0xC3CD
Size: 125 registers
• Window Status: The status of the current window. Since the time to prepare a window may exceed an acceptable modbus delay (1 second), this acts as a state flag, signifying when the window is ready for retrieval. When this value indicates that the window is not ready, the data in the window should be ignored. Window
Status is Read-only, any writes are ignored.
0 Window is Ready
0xFF Window is Not Ready
• Record Number: The record number of the first record in the data window. Setting this value controls which records will be available in the data window.
• When the log is engaged, the first (oldest) record is "latched." This means that record number 0 will always point to the oldest record at the time of latching, until the log is disengaged (unlocked).
• To retrieve the entire log using auto-increment, set this value to 0, and retrieve the window repeatedly, until all records have been retrieved.
• When auto-increment is enabled, this value will automatically increment so that the window will "page" through the records, increasing by RecordsPerWindow each time that the last register in the window is read.
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE B–13
APPENDIX B: MODBUS MAP AND RETRIEVING LOGS
• When auto-increment is not enabled, this value must be written-to manually, for each window to be retrieved.
• Log Retrieval Data Window: The actual data of the records, arranged according to the above settings.
Note
B.5.4 Log Retrieval
Log Retrieval is accomplished in 3 basic steps:
1.
Engage the log.
2.
Retrieve each of the records.
3.
Disengage the log.
B.5.4.1 Auto-Increment
In the traditional Modbus retrieval system, you write the index of the block of data to retrieve, then read that data from a buffer (window). To improve the speed of retrieval, the index can be automatically incremented each time the buffer is read.
In the EPM7000 meter, when the last register in the data window is read, the record index is incremented by the Records per Window.

Function Code 0x23 is a user defined Modbus function code, which has a format similar to Function Code 0x03, except for the inclusion of a "repeat count." The repeat count (RC) is used to indicate that the same N registers should be read RC number of times. (See the Number of Repeats bullet on page B-14.)
• By itself this feature would not provide any advantage, as the same data will be returned RC times. However, when used with auto-incrementing, this function condenses up to 8 requests into 1 request, which decreases communication time, as fewer transactions are being made.
• In the EPM7000 meter repeat counts are limited to 8 times for Modbus RTU, and 4 times for Modbus ASCII.
The response for Function Code 0x23 is the same as for Function Code 0x03, with the data blocks in sequence.

APPENDIX B: MODBUS MAP AND RETRIEVING LOGS
Note
Note
Before using function code 0x23, always check to see if the current connection
supports it. Some relay devices do not support user defined function codes; if that is the case, the message will stall. Other devices don't support 8 repeat counts.
B.5.4.3 Log Retrieval Procedure
The following procedure documents how to retrieve a single log from the oldest record to the newest record, using the "normal" record type (see Scope). All logs are retrieved using the same method. See Section B.5.4.4 for a Log Retrieval example.
• This example uses auto-increment.
• In this example, Function Code 0x23 is not used.
• You will find referenced topics in Section B.5.3. Block Definitions.
• Modbus Register numbers are listed in brackets.
1.
Engage the Log:
• Read the Log Status Block.
• Read the contents of the specific logs' status block [0xC737+, 16 reg]
(see Log Headers).
•
•
Store the # of Records Used, the Record Size, and the Log
Availability.
If the Log Availability is not 0, stop Log Retrieval; this log is not available at this time. If Log Availability is 0, proceed to step 1b
(Engage the log).
This step is done to ensure that the log is available for retrieval, as well as retrieving information for later use.
• Engage the log: write log to engage to Log Number, 1 to Enable, and the desired mode to Scope (default 0 (Normal)) [0xC34F, 1 reg]. This is best done as a singleregister write.
This step will latch the first (oldest) record to index 0, and lock the log so that only this port can retrieve the log, until it is disengaged.
• Verify the log is engaged: read the contents of the specific logs' status block
[0xC737+, 16 reg] again to see if the log is engaged for the current port (see Log
Availability). If the Log is not engaged for the current port, repeat step 1b (Engage the log).
• Write the retrieval information.
• Compute the number of records per window, as follows:
RecordsPerWindow = (246 \ RecordSize)
• If using 0x23, set the repeat count to 2-8. Otherwise, set it to 1.
• Since we are starting from the beginning for retrieval, the first record index is 0.
• Write the Records per window, the Number of repeats (1), and Record Index (0)
[0xC350, 3 reg].
This step tells the EPM7000 meter what data to return in the window.
2.
Retrieve the records:
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE B–15
APPENDIX B: MODBUS MAP AND RETRIEVING LOGS
Note
• Read the record index and window: read the record index, and the data window
[0xC351, 125 reg].
• If the meter Returns a Slave Busy Exception, repeat the request.
• If the Window Status is 0xFF, repeat the request.
• If the Window Status is 0, go to step 2b (Verify record index).
• We read the index and window in 1 request to minimize communication time, and to ensure that the record index matches the data in the data window returned.
• Space in the window after the last specified record (RecordSize x RecordPerWindow) is padded with 0xFF, and can be safely discarded.
• Verify that the record index incremented by Records Per Window. The record index of the retrieved window is the index of the first record in the window. This value will increase by Records Per Window each time the window is read, so it should be 0, N,
N x 2, N x 3. . . for each window retrieved.
• If the record index matches the expected record index, go to step 2c
(Compute next expected record index).
• If the record index does not match the expected record index, then go to step 1d (Write the retrieval information), where the record index will be the same as the expected record index. This will tell the EPM7000 meter to repeat the records you were expecting.
• Compute next Expected Record Index.
• If there are no remaining records after the current record window, go to step 3 (Disengage the log).
• Compute the next expected record index by adding Records Per
Window, to the current expected record index. If this value is greater than the number of records, re-size the window so it only contains the remaining records and go to step 1d (Write the retrieval information), where the Records Per Window will be the same as the remaining records.
3.
Disengage the log: write the Log Number (of log being disengaged) to the Log Index and 0 to the Enable bit [0xC34F, 1 reg].
B.5.4.4 Log Retrieval Example
The following example illustrates a log retrieval session. The example makes the following assumptions:
• Log Retrieved is Historical Log 1 (Log Index 2).
• Auto-Incrementing is used.
• Function Code 0x23 is not used (Repeat Count of 1).
• The Log contains Volts-AN, Volts-BN, Volts-CN (12 bytes).

• This retrieves the actual window. Repeat this command as many times as necessary to retrieve all of the records when auto-increment is enabled.
• Note the filler record. When a log is reset (cleared) in the meter, the meter always adds a first "filler" record, so that there is always at least 1 record in the log. This
"filler" record can be identified by the data being all 0xFF, and it being index 0. If a record has all 0xFF for data, the timestamp is valid, and the index is NOT 0, then the record is legitimate.
• When the "filler" record is logged, its timestamp may not be "on the interval." The next record taken will be on the next "proper interval," adjusted to the hour. For example, if the interval is 1 minute, the first "real" record will be taken on the next minute (no seconds). If the interval is 15 minutes, the next record will be taken at
:15, :30, :45, or :00 - whichever of those values is next in sequence.
6.
Compare the index with Current Index.
• The Current Index is 0 at this point, and the record index retrieved in step 5 is 0: thus we go to step 8.
• If the Current Index and the record index do not match, go to step 7. The data that was received in the window may be invalid, and should be discarded.

• This step manually sets the record index, and is primarily used when an out-oforder record index is returned on a read (step 6).
• The example assumes that the second window retrieval failed somehow, and we need to recover by requesting the records starting at index 13 again.

• This is the step that determines how much more of the log we need to retrieve.
• On the first N passes, Records Per Window should be 13 (as computed in step 4), and the current index should be a multiple of that (0, 13, 26, . . .). This amount will decrease when we reach the end (see step 10).
• If the current index is greater than or equal to the number of records (in this case
100), then all records have been retrieved; go to step 12. Otherwise, go to step 10 to check if we are nearing the end of the records.
10. If number records - current index < RecordsPerWindow, decrease to match.
• Here we bounds-check the current index, so we don't exceed the records available.
• If the number of remaining records (#records - current index) is less than the
Records per Window, then the next window is the last, and contains less than a full window of records. Make records per window equal to remaining records
(#records-current index). In this example, this occurs when current index is 91 (the
8'th window). There are now 9 records available (100-91), so make Records per
Window equal 9.

• If the record is "Going out of limit," this is the value of the limit when the
"Out" condition occurred.
• If the record is "Coming back into limit," this is the "worst" value of the limit during the period of being "out": for High (above) limits, this is the highest value during the "out" period; for Low (below) limits, this is the lowest value during the “out" period.

Interpretation of Alarm Data:
To interpret the data from the alarm records, you need the limit data from the
Programmable Settings [0x754B, 40 registers].
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE B–25
APPENDIX B: MODBUS MAP AND RETRIEVING LOGS
Note
There are 8 limits, each with an Above Setpoint, and a Below Setpoint. Each setpoint also has a threshold (hysteresis), which is the value at which the limit returns "into" limit after the setpoint has been exceeded. This prevents "babbling" limits, which can be caused by the limit value fluttering over the setpoint, causing it to go in and out of limit continuously.
• Identifier: The first modbus register of the value that is being watched by this limit.
While any modbus register is valid, only values that can have a Full Scale will be used by the EPM7000 meter.
• Above Setpoint: The percent of the Full Scale above which the value for this limit will be considered "out".
• Valid in the range of -200.0% to +200.0%
• Stored as an integer with 0.1 resolution. (Multiply % by 10 to get the integer, divide integer by 10 to get %. For example, 105.2% = 1052.)
• Above Hysteresis: The percent of the Full Scale below which the limit will return
"into" limit, if it is out. If this value is above the Above Setpoint, this Above limit will be disabled.
• Valid in the range of -200.0% to +200.0%.
• Stored as an integer with 0.1 resolution. (Multiply % by 10 to get the integer, divide integer by 10 to get %. For example, 104.1% = 1041.)
• Below Setpoint: The percent of the Full Scale below which the value for this limit will be considered "out".
• Valid in the range of -200.0% to +200.0%.
• Stored as an integer with 0.1 resolution. (Multiply % by 10 to get the integer, divide integer by 10 to get %. For example, 93.5% = 935.)
• Below Hysteresis: The percent of the Full Scale above which the limit will return
"into" limit, if it is out. If this value is below the Below Setpoint, this Below limit will be disabled.
• Valid in the range of -200.0% to +200.0%.
• Stored as an integer with 0.1 resolution. (Multiply % by 10 to get the integer, divide integer by 10 to get %. For example, 94.9% = 949.)
The Full Scale is the "nominal" value for each of the different types of readings. To compute the Full Scale, use the following formulas:
[CT Numerator] x [CT Multiplier]
[PT Numerator] x [PT Multiplier]
Current
Voltage
Power 3-Phase (WYE)
Power 3-Phase (Delta)
Power Single Phase (WYE)

• To interpret a limit alarm fully, you need both the start and end record (for duration).
• There are a few special conditions related to limits:
• When the meter powers up, it detects limits from scratch. This means that multiple "out of limit" records can be in sequence with no "into limit" records. Cross- reference the System Events for Power Up events.
• This also means that if a limit is "out," and it goes back in during the power off condition, no "into limit" record will be recorded.
• The "worst" value of the "into limit" record follows the above restrictions; it only represents the values since power up. Any values before the power up condition are lost.

Important Note Concerning the EPM7000 Meter's Modbus Map
In depicting Modbus Registers (Addresses), the EPM7000 meter's Modbus map uses
Holding Registers only.
B.6.1 Hex Representation
The representation shown in the table below is used by developers of Modbus drivers and libraries, SEL 2020/2030 programmers and Firmware Developers. The EPM7000 meter's
Modbus map also uses this representation.
Hex
0008 - 000F
Description
Meter Serial Number
B.6.2 Decimal Representation
The EPM7000 meter's Modbus map defines Holding Registers as (4X) registers. Many popular SCADA and HMI packages and their Modbus drivers have user interfaces that require users to enter these Registers starting at 40001. So instead of entering two separate values, one for register type and one for the actual register, they have been combined into one number.
The EPM7000 meter's Modbus map uses a shorthand version to depict the decimal fields, i.e., not all of the digits required for entry into the SCADA package UI are shown. For example:
You need to display the meter's serial number in your SCADA application. The EPM7000 meter's Modbus map shows the following information for meter serial number:
Decimal
9 - 16
Description
Meter Serial Number
In order to retrieve the meter's serial number, enter 40009 into the SCADA UI as the starting register, and 8 as the number of registers.
• In order to work with SCADA and Driver packages that use the 40001 to 49999 method for requesting holding registers, take 40000 and add the value of the register (Address) in the decimal column of the Modbus Map. Then enter the number (e.g., 4009) into the UI as the starting register.
• For SCADA and Driver packages that use the 400001 to 465536 method for requesting holding registers take 400000 and add the value of the register
(Address) in the decimal column of the Modbus Map. Then enter the number (e.g.,
400009) into the UI as the starting register. The drivers for these packages strip off the leading four and subtract 1 from the remaining value. This final value is used as the starting register or register to be included when building the actual modbus message.

1 output of analog board will follow the value of the register addressed here.
Value read from the source register at which High nominal current will be output. Example: for the 4-
20mA card, if this register is
2 programmed with 750, then the current output will be
20mA when the value read from the source register is
750.
Value read from the source register at which Low nominal current will be
2 output. Example: for the 4-
20mA card, if this register is programmed with 0, then the current output will be
4mA when the value read from the source register is 0.

Full range output for 0-1mA card only: A bit set(1) means full range (-1mA to +1mA); a bit cleared(0) means source only (0mA to +1mA).
Format of the polled register:f=float 32; s=signed
32 bit int; u=unsigned 32 bit int; w=signed 16 bit int; b=unsigned 16 bit int.
This register should be programmed with the address of the register whose value is to be used for current output. In different words, the current level

1 output of analog board will follow the value of the register addressed here.
Value read from the source register at which High nominal current will be output. Example: for the 4-
20mA card, if this register is
2 programmed with 750, then the current output will be
20mA when the value read from the source register is
750.
Value read from the source register at which Low nominal current will be
2 output. Example: for the 4-
20mA card, if this register is programmed with 0, then the current output will be
4mA when the value read from the source register is 0.

Data Formats
ASCII
SINT16 / UINT16
ASCII characters packed 2 per register in high, low order and without any termination characters. For example,
"EPM7000" would be 4 registers containing 0x5378, 0x6172, 0x6B32, 0x3030.
16-bit signed / unsigned integer.
32-bit signed / unsigned integer spanning 2 registers. The lower-addressed register is the high order half.
32-bit IEEE floating point number spanning 2 registers. The lower-addressed register is the high order half (i.e., contains the exponent).
3 adjacent registers, 2 bytes each. First (lowest-addressed) register high byte is year (0-99), low byte is month (1-
12). Middle register high byte is day(1-31), low byte is hour (0-23 plus DST bit). DST (daylight saving time) bit is bit
6 (0x40). Third register high byte is minutes (0-59), low byte is seconds (0-59). For example, 9:35:07AM on October
12, 2049 would be 0x310A, 0x0C49, 0x2307, assuming DST is in effect.

All registers not explicitly listed in the table read as 0. Writes to these registers will be accepted but won't actually change the register (since it doesn't exist).
Meter Data Section items read as 0 until first readings are available or if the meter is not in operating mode. Writes to these registers will be accepted but won't actually change the register.
Register valid only in programmable settings update mode. In other modes these registers read as 0 and return an illegal data address exception if a write is attempted.
Meter command registers always read as 0. They may be written only when the meter is in a suitable mode. The registers return an illegal data address exception if a write is attempted in an incorrect mode.
If the password is incorrect, a valid response is returned but the command is not executed. Use 5555 for the password if passwords are disabled in the programmable settings.
M denotes a 1,000,000 multiplier.
Each identifier is a Modbus register. For entities that occupy multiple registers (FLOAT, SINT32, etc.) all registers making up the entity must be listed, in ascending order. For example, to log phase A volts, VAs, voltage THD, and VA hours, the register list would be 0x3E7, 0x3E8, 0x411, 0x412, 0x176F, 0x61D, 0x61E and the number of registers (0x7917 high byte) would be 7.
Writing this register causes data to be saved permanently in nonvolatile memory. Reply to the command indicates that it was accepted but not whether or not the save was successful. This can only be determined after the meter has restarted.
Reset commands make no sense if the meter state is LIMP. An illegal function exception will be returned.
Energy registers should be reset after a format change.
Entities to be monitored against limits are identified by Modbus address. Entities occupying multiple Modbus registers, such as floating point values, are identified by the lower register address. If any of the 8 limits is unused, set its identifier to zero. If the indicated Modbus register is not used or is a nonsensical entity for limits, it will behave as an unused limit.
There are 2 setpoints per limit, one above and one below the expected range of values. LM1 is the "too high" limit, LM2 is "too low". The entity goes "out of limit" on LM1 when its value is greater than the setpoint. It remains "out of limit" until the value drops below the in threshold. LM2 works similarly, in the opposite direction. If limits in only one direction are of interest, set the in threshold on the "wrong" side of the setpoint. Limits are specified as % of full scale, where full scale is automatically set appropriately for the entity being monitored: current voltage single phase power

APPENDIX B: MODBUS MAP AND RETRIEVING LOGS
16 Measurement states: Off occurs during programmable settings updates; Run is the normal measuring state; Limp indicates that an essentail non-volatile memory block is corrupted; and Warmup occurs briefly (approximately 4 seconds) at startup while the readings stabilize. Run state is required for measurement, historical logging, demand interval processing, limit alarm evaluation, min/max comparisons, and THD calculations. Resetting min/max or energy is allowed only in run and off states; warmup will return a busy exception. In limp state, the meter reboots at 5 minute intervals in an effort to clear the problem.
Limits evaluation for all entites except demand averages commences immediately after the warmup period. Evaluation for demand averages, maximum demands, and minimum demands commences at the end of the first demand interval after startup.
Autoincrementing and function 35 must be used when retrieving waveform logs.
Depending on the Option selected, there are 15, 29, or 45 flash sectors available in a common pool for distribution among the
3 historical and waveform logs. The pool size, number of sectors for each log, and the number of registers per record together determine the maximum number of records a log can hold.
S = number of sectors assigned to the log,
H = number of Modbus registers to be monitored in each historical record (up to 117),
R = number of bytes per record = (12 + 2H) for historical logs
N = number of records per sector = 65516 / R, rounded down to an integer value (no partial records in a sector)
T = total number of records the log can hold = S * N
T = S * 2 for the waveform log.
Only 1 input on all digital input cards may be specified as the end-of-interval pulse.
Logs cannot be reset during log retrieval. Waveform log cannot be reset while storing a capture. Busy exception will be returned.
Combination of class and type currently defined are:
0x23 = Fiber cards
0x24 = Network card
0x41 = Relay card
0x42 = Pulse card

Appendix C: DNP Mapping
DNP Mapping
C.1
Overview
This Appendix describes the functionality of the EPM7000 meter's version of the DNP protocol. A DNP programmer must follow this information in order to retrieve data from the
EPM7000 meter. The DNP used by the EPM7000 is a reduced set of the Distributed Network
Protocol Version 3.0 subset 2; it gives enough functionality to get critical measurements from the EPM7000 meter.
The EPM7000 meter's DNP version supports Class 0 object/qualifiers 0,1,2,6, only. No event generation is supported. The EPM7000 meter always acts as a secondary device (slave) in
DNP communication.
A new feature allows DNP readings in primary units with user-set scaling for current, voltage, and power. (See Chapter 5 in the GE Communicator EXT User Manual for instructions.)
MULTILIN EPM7000 - POWER QUALITY METER – USER GUIDE C–1
APPENDIX C: DNP MAPPING
C.2
Physical Layer
The EPM7000 meter's DNP version uses serial communication. It can be assigned to Port 2
(RS485 compliant port) or any communication capable option board. Speed and data format is transparent for the EPM7000 meter's DNP version: they can be set to any supported value. The IrDA port cannot use the EPM7000 meter's DNP version.

C.3
Data Link Layer
The EPM7000 meter can be assigned with a value from 1 to 65534 as the target device address. The data link layer follows the standard frame FT3 used by the DNP Version 3.0 protocol, but only 4 functions are implemented: Reset Link, Reset User, Unconfirmed User
Data, and Link Status, as depicted in the following table.

[dst] and [src] are the device address of the EPM7000 Meter and Master device, respectively. Refer to Section C.7 for more detail on supported frames for the data link layer.
In order to establish a clean communication with the EPM7000 meter, we recommended you perform the Reset Link and Reset User functions. The Link Status is not mandatory but if queried it will be attended to. The inter-character time-out for the EPM7000 meter's DNP version is 1 second. If this amount of time, or more, elapses between two consecutive characters within a FT3 frame, the frame will be dropped.

C.4
Application Layer
In the EPM7000 meter, the EPM7000 meter's DNP version supports the Read function,
Write Function, the Direct Operate function and the Direct Operate Unconfirmed function.
• The Read function (code 01) provides a means for reading the critical measurement data from the meter. This function should be posted to read object
60 variation 1, which will read all the available Class 0 objects from the register map of the EPM7000 meter's DNP version. See register map in Section C.6. In order to retrieve all objects with their respective variations, the qualifier must be set to
ALL (0x06). See Section C.7 for an example showing a read Class 0 request data from the meter.
• The Write function (code 02) provides a mean for clearing the Device restart bit in the Internal Indicator register only. This is mapped to Object 80, point 0 with variation 1. When clearing the restart device indicator use qualifier 0. Section C.7 shows the supported frames for this function.
• The Direct Operate function (code 05) is intended for resetting the energy counters and the demand counters (minimum and maximum energy registers). These actions are mapped to Object 12, point 0 and point 2, that are seen as a control relay. The relay must be operated (On) in 0 msec and released (Off) in 1 msec only.
Qualifiers 0x17 or x28 are supported for writing the energy reset. Sample frames are shown in Section C.7.
• The Direct Operate Unconfirmed (or Unacknowledged) function (code 06) is intended for asking the communication port to switch to Modbus RTU protocol from the EPM7000 meter's DNP version. This switching is seen as a control relay mapped into Object 12, point 1 in the meter. The relay must be operated with qualifier 0x17, code 3 count 0, with 0 millisecond on and 1 millisecond off, only.
After sending this request the current communication port will accept Modbus RTU frames only. To make this port go back to DNP protocol, the unit must be powerrecycled. Section C.7 shows the constructed frame to perform DNP to Modbus RTU protocol change.

Error Reply
In the case of an unsupported function, or any other recognizable error, an error reply will be generated from the EPM7000 meter to the Primary station (the requester). The Internal
Indicator field will report the type of error: unsupported function or bad parameter.
The broadcast acknowledge and restart bit, are also signaled in the internal indicator but they do not indicate an error condition.

Internal Indication Bits
Bits implemented in the EPM7000 meter are listed below. All others are always reported as zeroes.
Bad Function
Occurs if the function code in a User Data request is not Read (0x01), Write (0x02),
Direct Operate (0x05), or Direct Operate, No Ack (0x06).
Object Unknown
Occurs if an unsupported object is specified for the Read function. Only objects 10, 20,
30, and 60 are supported.
Out of Range
Occurs for most other errors in a request, such as requesting points that don’t exist or direct operate requests in unsupported formats.
Buffer Overflow
Occurs if a read request or a read response is too large for its respective buffer. In general, if the request overflows, there will be no data in the response while if the response overflows at least the first object will be returned. The largest acceptable request has a length field of 26, i.e. link header plus 21 bytes more, not counting checksums. The largest possible response has 7 blocks plus the link header.
