Introduction

EasyLogicTMPM1130H/EM6438H
management can eliminate meter readings and get advanced payments, the customers can be freed of penalty through already stored energy consumption as against unit consumption.
The meter supports prepaid energy metering. Customers can add on energy credits to the balance register of the meter through communication only. The meter starts deducting the units based on energy consumption.
The customer can set a minimum value for energy credits consumption, beyond which the meter raises an alarm. The meter indicates the alarm through front panel LED, by blinking the top most LED on the load bar. In situations where the energy credits get exhausted, the meter switches on the relay. Beyond which, if the energy consumption continues, the meter keeps accumulating negative balance. When the customers recharge the next time, the negative accumulated energy will get deducted and only the balance energy will get credited for use.

Direct connect voltage limitsMeasuring voltage limit

You can connect the meter’s voltage inputs directly to the phase voltage lines of the power system if the power system’s line-to-line or line-to-neutral voltages do not exceed the meter’s direct connect maximum voltage limits.
The meter’s voltage measurement inputs are rated by the manufacturer for up to 277 V L-N / 480 V L-L. However, the maximum voltage allowed for direct connection may be lower, depending on the local electrical codes and regulations. As per installation category III the maximum voltage on the meter voltage measurement inputs should not exceed 277 V L-N / 480 V L-L.
If your system voltage is greater than the specified direct connect maximum voltage, you must use VTs (voltage transformers) to step down the voltages.

Balanced system considerations
In situations where you are monitoring a balanced 3-phase load, you may choose to connect only one or two CTs on the phase(s) you want to measure, and then configure the meter so it calculates the current on the unconnected current input(s).
NOTE: For a balanced 4-wire Wye system, the meter’s calculations assume that there is no current flowing through the neutral conductor.
Balanced 3-phase Wye system with 2 CTs
The current for the unconnected current input is calculated so that the vector sum for all three phases equal zero.
Balanced 3-phase Wye or Delta system with 1CT
The currents for the unconnected current inputs are calculated so that their magnitude and phase angle are identical and equally distributed, and the vector sum for all three phase currents equal zero.
NOTE: You must always use 3 CTs for 3-phase 4-wire center-tapped Delta or center-tapped open Delta systems.

Serial communications
The meter supports serial communication through the RS-485 port.
In an RS-485 network, there is one master device, typically an Ethernet to RS-485 gateway. It provides the means for RS-485 communications with multiple slave devices (for example, meters). For applications that require only one dedicated computer to communicate with the slave devices, an RS-232 to RS-485 converter can be used as the master device. In master device, recommended response time-out setting should be minimum 1 second.

RS-485 configuration

Before connecting your device to the RS-485 bus, use the meter’s display, or ION Setup to configure your meter’s default RS-485 settings.

QGH1336303-05

Hardware reference
Serial protocols RS-485 wiring

EasyLogicTMPM1130H/EM6438H
Your meter has one RS-485 connection.
Your meter must have a unique unit identifier (address) and have the following settings match the rest of the devices on the RS-485 bus:
· Protocol · Baud rate · Parity You can use a communications converter (USB to RS-485 or RS-232 to RS-485) to connect to your meter.

Your meter supports the serial communication protocol on its RS-485 port. · Modbus RTU

Connect the devices on the RS-485 bus in a point-to-point configuration, with the (+) and (-) terminals from one device connected to the corresponding (+) and (-) terminals on the next device.

RS-485 cable
Use a shielded 2 wire or 1 twisted pair RS-485 cable to wire the devices. Use either shielded 2 wire or 1 twisted pair to connect the (+) and (-) terminals.
The total distance for devices connected on an RS-485 bus should not exceed 900 m (2953 ft).
NOTE: You can connect a maximum of 32 devices to a single RS-485 bus.

RS-485 terminals

–

Data minus. This transmits/receives the inverting data signals.

+ Data plus. This transmits/receives the non-inverting data signals.

RS-485 network configuration
After you have wired the RS-485 port and powered up the meter, you must configure the serial communications port in order to communicate with the meter.
Each device on the same RS-485 communications bus must have a unique address and all connected devices must be set to the same protocol, baud rate, and parity (data format).
NOTE: To communicate with the meter using ION Setup, you must set the serial site and all connected devices in the RS-485 network to the same parity setting.
For meters that do not have a display, you must first wire and configure each one separately before connecting these meters to the same RS-485 bus.

Relay and Alternate source sense

Relay and Alternate source sense

Alternate source sense
Alternate source sense terminals detect the status of alternate power sources.
Source 1 in the meter connects to utility and Source 2 connects to alternate source. The two terminals are connected with a 1Ph LN alternate power source. When Source 2 is turned on, voltage flows through the meter and the system is powered with alternate source.
The meter measures energy accumulation and run hours on the alternate source. The total energy used by the meter is the sum of accumulated energy for Source 1 and Source 2. Total run hours of the meter is the sum of run hours of Source 1 and Source 2. Total accumulated energy, and run hours can be viewed through meter display, and through communication.
NOTE: Old accumulated energy and run hours can be viewed through display and communication for Source 1 and Source 2.

Relay

Relay is used to trigger an alarm or a secondary system based on a preset condition in the meter.
The relay is Normally Open (NO) when not triggered. When triggered (operated) it changes to Normally Closed (NC).
A relay can be triggered depending on source of operation. The supplied source can be utility, alternate source, or both.
The following parameters are associated to trigger a relay. The relay gets trigger if the mentioned conditions are met.

UL functionality

LL functionality

The UL can be set at a maximum of 99999 kW. you can set UL only through communication.

The LL can be set to any minimum value defined. You can set LL only through communication. When the energy credits reaches LL, an alarm gets trigger to indicate limited consumption. This alarm is displayed by the top most LED on the load bar blinking constantly. When the energy credit goes to 0, the relay gets triggered. If the energy consumption continues, the energy credits display a negative value that is balanced after the next recharge.
NOTE: If you set LL as 0, the alarm functionality is disabled.

Two different parameters can be set simultaneously for the relay trigger functionality with separate upper and lower limits for each parameter.
· Parameter associated with Source 1 (or 2)
· Parameter associated with Source 2 (or 1) or both (1 and 2)
For a relay to operate, the power or demand parameter must be same as configured in the meter. The meter does not allow users to configure any other parameter apart from the configured power or demand parameters.
NOTE: Configuration is not allowed if both parameters are same.
Only one parameter can be configured, associating it with the source (as per the system connected). The other parameter must be set to zero (with zero as UL and zero as LL).
To trigger or restore a relay status, you can manually program a time delay. The delay can be set between 1-60 seconds. The set time enables the triggering or restoration of the associated relay during a fault occurrences.

Measurements and calculations

Measurements and calculations

Meter initialization
Meter Initialization is a special command that clears the meter’s energy, power, demand values, and meter operation timer.
It is common practice to initialize the meter after its configuration is completed, before adding it to an energy management system.
After configuring all the meter setup parameters, navigate through the different meter display screens and make sure the displayed data is valid then perform meter initialization.
NOTE: You can perform meter initialization using ION setup and secured command interface.

Real-time readings
The meter measures currents and voltages, and reports in real time the RMS (Root Mean Squared) values for all three phases and neutral.
The voltage and current inputs are continuously monitored at a sampling rate of 64 samples per cycle. This amount of resolution helps enable the meter to provide reliable measurements and calculated electrical values for various commercial, buildings and industrial applications.

Power and Energy measurements
The meter lets you configure any one power parameter (W, VA, or VAR) at a time. You can set it using the meter’s display, through communication using ION Setup, or by any Modbus tool that supports FC16 (command number is 2959).
Energy accumulation in the meter depends on the selected power parameter (W, VA, or VAR). Integrated energy values and old values also depends on the selected power parameter.
NOTE:
· On changing the power parameter (either through meter display or communication), all the stored energy values (old and integrated) are reset to zero.
· Energy values can also be cleared through communication. Run Hours are displayed with 6 digit Hours and 2 Digit Minutes.

Applicable for METSEPM1130HCL5LVD NOTE: Based on the energy scale selection, all the energy parameter values will reset when any of the energy parameter exceeds 99999.999.

Power demand

Power demand is a measure of average power consumption over a fixed time interval.
Only one demand parameter can be set at a given time. You can set it using the meter’s display, through communication using ION setup, or by using any Modbus tool that supports FC16.
The list of demand parameters that can be configured are :
· VA demand
· VAR demand
· W demand
Last demand: This demand updates in the NVRAM of the meter at the end of a demand interval. The present value at the end of the demand interval updates to last demand.
Present demand: The demand calculated by dividing energy accumulated during a specified period by length of that period.
Peak demand: Peak Demand is the highest recorded demand value in NVRAM. It is not dependent on any interval or cycle. Unless there is no value recorded higher than the current value of the peak demand, the peak demand value will not update. The meter displays the peak demand occurrence time. The meter takes a snapshot of meter On hours at which the peak demand occurred.
NOTE: This value gets cleared or reset when demand configuration is changed to other configuration parameter or when the demand parameter is reset in the meter.
The meter measures instantaneous consumption and can calculate demand using various methods.

Power demand calculation methods
Power demand is calculated by dividing the energy accumulated during a specified period by the length of that period.
How the meter performs this calculation depends on the method and time parameters you select (for example, timed rolling block demand with a 15 – minute interval and 5 – minute subinterval).
To be compatible with electric utility billing practices, the meter provides the following types of power demand calculations:
· Block interval demand
You can configure the power demand calculation method from the display or software.

Block interval demand
For block interval demand method types, you specify a period of time interval (or block) that the meter uses for the demand calculation.
Select/configure how the meter handles that interval from one of these different methods:

Power quality

Power quality

Harmonics overview
This section describes the meter’s power quality features and how to access power quality data. The meter measures voltage and current harmonics up to the 15th harmonic to calculate Total Harmonic Distortion (THD%).
Harmonics are integer multiples of the fundamental frequency of the power system. Harmonics information is required for compliance to system power quality standards such as EN50160 and meter power quality standards such as IEC 61000-4-30.
The meter measures fundamental and higher harmonics relative to the fundamental frequency. The meter’s power system setting defines which phases are present and determines how line-to-line or line-to-neutral voltage harmonics and current harmonics are calculated.
Harmonics are used to identify whether the supplied system power meets required power quality standards, or if non-linear loads are affecting your power system. Power system harmonics can cause current flow on the neutral conductor, and damage to equipment such as increased heating in electric motors. Power conditioners or harmonic filters can be used to minimize unwanted harmonics.

Total harmonic distortion %
Total harmonic distortion (THD%) is a measure of the total per-phase voltage or current harmonic distortion present in the power system.
THD% provides a general indication of the quality of a waveform. THD% is calculated for each phase of both voltage and current.

THD% calculations

THD% is a quick measure of the total distortion present in a waveform and is the ratio of harmonic content (HC) to the fundamental harmonic (H1).
By default, the meter uses the following equation to calculate THD%:
H THD = —–C— x 100%
H

Verifying accuracy

Verifying accuracy

Overview of meter accuracy
All meters are tested and verified at the factory in accordance with International Electrotechnical Commission (IEC) and Institute of Electrical and Electronics Engineers (IEEE) standards.
Your meter typically does not require re-calibration. However, in some installations a final accuracy verification of the meters is required, especially if the meters will be used for revenue or billing applications.

Accuracy test requirements
The most common method for testing meter accuracy is to apply test voltages and currents from a stable power source and compare the meter’s readings with readings from a reference device or energy standard.
Signal and power source
The meter maintains its accuracy during voltage and current signal source variations but its energy pulsing output needs a stable test signal to help produce accurate test pulses. The meter’s energy pulsing mechanism needs approximately 10 seconds to stabilize after every source adjustment.
The meter must be connected to control power in order to conduct accuracy verification testing. Refer to your meter’s installation documentation for power supply specifications.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Verify the device’s power source meets the specifications for your device’s power supply.
Failure to follow these instructions will result in death or serious injury.

Control equipment Environment

Control equipment is required for counting and timing the pulse outputs from an energy pulsing LED.
· Most standard test benches have an arm equipped with optical sensors to detect LED pulses (the photodiode circuitry converts detected light into a voltage signal).
· The reference device or energy standard typically has digital inputs that can detect and count pulses coming from an external source (i.e., the meter’s pulse output). NOTE: The optical sensors on the test bench can be disrupted by strong sources of ambient light (such as camera flashes, florescent tubes, sunlight reflections, floodlights, etc.). This can cause test errors. Use a hood, if necessary, to block out ambient light.
The meter should be tested at the same temperature as the testing equipment. The ideal temperature is about 23 ºC (73 ºF). Make sure the meter is warmed up sufficiently before testing.

58

QGH1336303-05

Verifying accuracy

EasyLogicTMPM1130H/EM6438H

A warm-up time of 30 minutes is recommended before beginning energy accuracy verification testing. At the factory, the meters are warmed up to their typical operating temperature before calibration to help ensure that the meters will reach their optimal accuracy at operating temperature.
Most high precision electronic equipment requires a warm up time before it reaches its specified performance levels. Energy meter standards allow the manufacturers to specify meter accuracy derating due to ambient temperature changes and self-heating.
Your meter complies with and meets the requirements of these energy metering standards.
For a list of accuracy standards that your meter complies to, contact your local Schneider Electric representative or download the meter brochure from www.se.com.

Reference device or energy standard
To help ensure the accuracy of the test, it is recommended that you use a reference device or reference energy standard with a specified accuracy that is 6 to 10 times more accurate than the meter under test. Before you start testing, the reference device or energy standard should be warmed up as recommended by its manufacturer.
NOTE: Verify the accuracy and precision of all measurement equipment used in accuracy testing (for example, voltmeters, ammeters, power factor meters).

Verifying accuracy test
The following tests are guidelines for accuracy testing your meter; your meter shop may have specific testing methods.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH · Apply appropriate Personal Protective Equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, CSA Z462 or other local standards. · Turn off all power supplying this device and the equipment in which it is installed before working on or in the equipment. · Always use a properly rated voltage sensing device to confirm that all power is off. · Do not exceed the maximum ratings of this device. · Verify the device’s power source meets the specifications for your device’s power supply. Failure to follow these instructions will result in death or serious injury.
1. Turn off all power supplying this device and the equipment in which it is installed before working on the device or equipment.

Option Energy pulsing LED
Pulse output

Description
Align the red light sensor on the standard test bench armature over the energy pulsing LED.
Connect the meter’s pulse output to the standard test bench pulse counting connections.

NOTE: When selecting which method to use, be aware that energy pulsing LEDs and pulse outputs have different pulse rate limits.
5. Before performing the verification test, let the test equipment power up the meter and apply voltage for at least 30 seconds. This helps stabilize the internal circuitry of the meter.
6. Configure the meter’s parameters for verifying accuracy testing.
7. Depending on the method selected for counting the energy pulses, configure the meter’s energy pulsing LED or one of the pulse outputs to perform energy pulsing. Set the meter’s energy pulse constant so it is in sync with the reference test equipment.
8. Perform accuracy verification on the test points. Run each test point for at least 30 seconds to allow the test bench equipment to read an adequate number of pulses. Allow 10 seconds of dwell time between test points.

Required pulses calculation for accuracy verification testing
Accuracy verification test equipment typically requires you to specify the number of pulses for a specific test duration.
The reference test equipment typically requires you to specify the number of pulses required for a test duration of “t” seconds. Normally, the number of pulses required is at least 25 pulses, and the test duration is greater than 30 seconds.
Use the following formula to calculate the required number of pulses:
Number of pulses = Ptot x K x t/3600
Where:

Verifying accuracy

EasyLogicTMPM1130H/EM6438H
· Ptot = total instantaneous power in kilowatts (kW) · K = the meter’s pulse constant setting, in pulses per kWh · t = test duration, in seconds (typically greater than 30 seconds)

Total power calculation for accuracy verification testing
Accuracy verification testing supplies the same test signal (total power) to both the energy reference/standard and the meter under test.
Total power is calculated as follows, where: · Ptot = total instantaneous power in kilowatts (kW) · VLN = test point line-to-neutral voltage in volts (V) · I = test point current in amps (A) · PF = power factor
The result of the calculation is rounded up to the nearest integer.
For a balanced 3­phase Wye system:
Ptot = 3 x VLN x I x PF x 1 kW/1000 W NOTE: A balanced 3­phase system assumes that the voltage, current and power factor values are the same for all phases.
For a single-phase system:
Ptot = VLN x I x PF x 1 kW/1000W

Percentage error calculation for accuracy verification testing
Accuracy verification testing requires you to calculate the percentage error between the meter being tested and the reference/standard.
Calculate the percentage error for every test point using the following formula:
Energy error = (EM – ES) / ES x 100%
Where: · EM = energy measured by the meter under test · ES = energy measured by the reference device or energy standard. NOTE: If accuracy verification reveals inaccuracies in your meter, they may be caused by typical sources of test errors. If there are no sources of test errors present, please contact your local Schneider Electric representative.

Accuracy verification test points
The meter should be tested at full and light loads and at lagging (inductive) power factors to help ensure testing over the entire range of the meter.
The test amperage and voltage input rating are labeled on the meter. Refer to the installation sheet or data sheet for your meter’s nominal current, voltage and frequency specifications.

Energy pulsing considerations

The meter’s energy pulsing LED and pulse outputs are capable of energy pulsing within specific limits.

Description Maximum pulse frequency Minimum pulse constant Maximum pulse constant

Energy pulsing LED 35 Hz 1 pulse per k_h 9,999,000 pulses per k_h

Pulse output 20 Hz

The pulse rate depends on the voltage, current and PF of the input signal source, the number of phases, and the VT and CT ratios.

If Ptot is the instantaneous power (in kW) and K is the pulse constant (in pulses per kWh), then the pulse period is:

Pulse period (in seconds) = 3600 =

1

K x Ptot Pulse frequency (Hz)

VT and CT considerations

Total power (Ptot) is derived from the values of the voltage and current inputs at the secondary side, and takes into account the VT and CT ratios.

The test points are always taken at the secondary side, regardless of whether VTs or CTs are used.

If VTs and CTs are used, you must include their primary and secondary ratings in the equation. For example, in a balanced 3-phase Wye system with VTs and CTs:

Ptot = 3 x VLN x

where Ptot = total power, VTp = VT primary, VTs = VT secondary, CTp = CT primary, CTs = CT secondary and PF = power factor.

Example calculations

This example calculation shows how to calculate power, pulse constants and maximum pulse frequency, and how to determine a pulse constant that reduces the maximum pulse frequency.

A balanced 3-phase Wye system uses 480:120 volt VTs and 120:5 amp CTs. The signals at the secondary side are 119 volts line-to-neutral and 5.31 amps, with a power factor of 0.85. The desired pulse output frequency is 20 Hz (20 pulses per second).
1. Calculate the typical total output power (Ptot):

Ptot = 3 x 119 x 480 x 5.31 x 120 x 0.85 x 1 kW = 154.71 kW

120

1000 W

2. Calculate the pulse constant (K):

3600 x (pulse frequency) K =

=

Ptot

3600 seconds/hour x 20 pulses/second 154.71 kW

K = 465.5 pulses / kWh

3. At full load (120% of nominal current = 6 A) and power factor (PF = 1), calculate the maximum total output power (Pmax):

Pmax = 3 x 119 x 480 x 6 x 100 x 1 x 1 kW = 205.6 kW

120

5

1000 W

4. Calculate the maximum output pulse frequency at Pmax:

Maximum pulse frequency = K x Pmax = 465.5 pulses / kWh x 205.6 kW

3600

3600 seconds/hour

Maximum pulse frequency = 26.6 pulses/second = 26.6 Hz
5. Check the maximum pulse frequency against the limits for the LED and pulse outputs:
· 26.6 Hz LED maximum pulse frequency (35 Hz)
· 26.6 Hz > pulse output maximum pulse frequency (20 Hz)
NOTE: The maximum pulse frequency is within the limits for LED energy pulsing. However, the maximum pulse frequency is greater than the limits for pulse output energy pulsing. Pulse output frequencies greater than 20 Hz will saturate the pulse output and cause it to stop pulsing. Therefore in this example, you can only use the LED for energy pulsing.

Adjustments to allow energy pulsing at the pulse outputs

If you want to use the pulse output, you must reduce the output pulse frequency so it is within the limits.

Using the values from the above example, the maximum pulse constant for the pulse output is:

Kmax = 3600 x (pulse output maximum pulse frequency) = 3600 x 20

Pmax

205.6

Kmax = 350.14 pulses per kWh

1. Set the pulse constant (K) to a value below Kmax, for example, 300 pulses/ kWh. Calculate the new maximum output pulse frequency at Pmax:

New maximum pulse frequency = K x Pmax = 300 pulses/kWh x 205.6 kW

3600

3600 seconds/hour

New maximum pulse frequency = 17.1 pulses/second = 17.1 Hz

QGH1336303-05

Verifying accuracy

2. Check the new maximum pulse frequency against the limits for the LED and pulse outputs:
· 17.1 Hz LED maximum pulse frequency (35 Hz)
· 17.1 Hz pulse output maximum frequency (20 Hz)
As expected, changing K to a value below Kmax allows you to use the pulse output for energy pulsing.
3. Set the new pulse constant (K) on your meter.

Typical sources of test errors
If you see excessive errors during accuracy testing, examine your test setup and test procedures to eliminate typical sources of measurement errors.
Typical sources of accuracy verification testing errors include:
· Loose connections of voltage or current circuits, often caused by worn-out contacts or terminals. Inspect terminals of test equipment, cables, test harness and the meter under test.
· Meter ambient temperature is significantly different than 23 °C (73 °F).
· Floating (ungrounded) neutral voltage terminal in any configuration with unbalanced phase voltages.
· Inadequate meter control power, resulting in the meter resetting during the test procedure.
· Ambient light interference or sensitivity issues with the optical sensor.
· Unstable power source causing energy pulsing fluctuations.
· Incorrect test setup: not all phases connected to the reference device or the energy standard. All phases connected to the meter under test should also be connected to the reference meter/standard.
· Moisture (condensing humidity), debris or pollution present in the meter under test.

Power and power factor
Power and power factor

EasyLogicTMPM1130H/EM6438H

Power and power factor
The sampled measurements taken at the meter’s voltage and current inputs provide data for calculating power and power factor.
In a balanced 3-phase alternating current (AC) power system source, the AC voltage waveforms on the current-carrying conductors are equal but offset by onethird of a period (a phase angle shift of 120 degrees between the three voltage waveforms).

Current phase shift from voltage

Electrical current can lag, lead, or be in phase with the AC voltage waveform, and is typically associated with the type of load — inductive, capacitive or resistive.
For purely resistive loads, the current waveform is in phase with the voltage waveform. For capacitive loads, current leads voltage. For inductive loads, current lags voltage.
The following diagrams show how voltage and current waveforms shift based on load type under ideal (laboratory) conditions.

Current and voltage in phase (resistive) Current leads voltage (capacitive)

Current lags voltage (inductive)

Real, reactive and apparent power (PQS)
A typical AC electrical system load has both resistive and reactive (inductive or capacitive) components.
Real power, also known as active power (P) is consumed by resistive loads. Reactive power (Q) is either consumed by inductive loads or generated by capacitive loads.
Apparent power (S) is the capacity of your measured power system to provide real and reactive power.
The units for power are watts (W or kW) for real power P, vars (VAR or kVAR) for reactive power Q, and volt-amps (VA or kVA) for apparent power S.

Power flow

Positive real power P(+) flows from the power source to the load. Negative real power P(-) flows from the load to the power source.

Power factor (PF)
Power factor (PF) is the ratio of real power (P) to apparent power (S).
Power factor is provided as a number between -1 and 1 or as a percentage from -100% to 100%, where the sign is determined by the convention.
PF = –P
S
An ideal, purely resistive load has no reactive components, so its power factor is one (PF = 1, or unity power factor). Inductive or capacitive loads introduce a reactive power (Q) component to the circuit which causes the PF to become closer to zero.

True PF

The meter supports true power factor values: · True power factor includes harmonic content.

Power factor sign convention
Power factor sign (PF sign) can be positive or negative, and is defined by the conventions used by IEC standards.

PF sign convention: IEC
PF sign correlates with the direction of real power (kW) flow. · Quadrant 1 and 4: Positive real power (+kW), the PF sign is positive (+).

There are two command interfaces, protected and unprotected, described in the following sections.

Using protected command interface
To issue a meter command using the protected command interface, you must have a command semaphore.
To get a semaphore, read the semaphore Modbus register. The power meter will return a zero or a nonzero number.
· If the meter shows zero, someone else owns the semaphore. You must wait for the semaphore to be available before sending a command.

· If the meter shows a nonzero number, you own the semaphore. Semaphore is provided once until it is released or has been inactive for approximately 4 minutes. Once you have the semaphore, subsequent reads of the semaphore register will return zero until you release the semaphore or it times out.
To send a meter command using the protected command interface:
1. Read the semaphore register and record the meter response. This is your semaphore.
2. Build the packet to be written to the command block.
3. Write the packet as a Modbus block write (enter the command number, semaphore, and parameters at the same time).
