Throughout this document, the phase-to-neutral notations of A/B/C and L1/L2/L3 as well as the phaseto-phase notations of AB/BC/CA and L12/L23/L31 may be used interchangeably for specifying a certain parameter to be a phase-to-neutral or phase-to-phase value, respectively.

The following sections illustrate the available measurements for each display option. Depending on the Wiring Mode selected, certain measurements may not be available. For example, the per-phase Uln, Uln Average, I4, per-phase kW, kvar, kVA and PF measurements are not available when the Wiring Mode is set to 3P3W or 1P2W L-L.

3.1.2.1 U/I

Notes:

1) This parameter only appears if the meter is equipped with the corresponding I4 option.

2) This screen only shows a valid value when the Wiring Mode is set to 3P3W or 3P4W, otherwise, it shows “0”.

3) For U/I Fundamental:

Chapter 4 Applications

4.1 Inputs and Outputs

4.1.1 Digital Inputs

The PMC-53A-E comes standard with four self-excited Digital Inputs that are internally wetted at 24 VDC with a sampling frequency of 1000Hz and programmable debounce. The PMC-53A-E provides the following programmable functions for its digital inputs:

1) Digital Input The digital inputs are typically used for status monitoring which can help

prevent equipment damage, improve maintenance, and track security breaches. The real-time statuses of the Digital Inputs are available on the Front Panel LCD Display as well as through communications. Changes in Digital Input status are stored as events in the SOE Log in 1 ms resolution.

2) Pulse Counting Pulse counter is supported with programmable Pulse Weight and

facilitates WAGES (Water, Air, Gas, Electricity and Steam) information collection.

3) Tariff Switching Up to 3 Digital Inputs may be used to select to which of the 8 Tariffs the

energy consumption should be accumulated. The 3 Digital Inputs (DI1, DI2 and DI3) represent 3 binary digits where Tariff 1=000, Tariff 2=001, …, Tariff 8=111 where DI1 represents the least significant digit and DI3 represents the most significant digit. The DI1 Function setup register must first be programmed as a Tariff Switch before configuring DI2 with the same function. In other words, if DI1 is configured as a Digital Input or Energy Pulse Counter and DI2 is configured as a Tariff Switch, the TOU will continue to function based on the TOU Schedule.

The following table describes the DI’s setup parameters:

Default*

Table 4-1 DI Setup Parameters

4.1.2 Digital Outputs

The PMC-53A-E comes standard with two Form A Electrometrical Relays. Digital Outputs are normally used for setpoint alarming, load control, or remote control applications.

Digital Outputs on the PMC-53A-E can be used in the following applications:

1) Front Panel Control Manually operated from the Front Panel. Please refer to the DO Control

setup parameter in Section 3.1.3 for a detailed description.

2) Remote Control Remotely operated over communications via our free PMC Setup

software or PecStar® iEMS Integrated Energy Management System.

3) Control Setpoint Control Setpoints can be programmed to trigger DO action upon

becoming active. Please refer to Section 4.4 for a detailed description.

Since there are multiple ways to trigger the Digital Outputs on the PMC-53A-E, a prioritized scheme has been developed to avoid conflicts between different applications. In general, Front Panel Control has the highest priority and can override other control schemes. Remote Control and Control Setpoint share the same priority, meaning that they can all be programmed to control the same Digital Output. This

scheme is equivalent to having an implicit Logical OR operation for the control of a Digital Output and may be useful in providing a generic alarm output signal. However, the sharing of a Digital Output is not recommended if the user intends to generate a control signal in response to a specific setpoint condition.

4.1.3 Energy Pulse Outputs

The PMC-53A-E comes standard with one Front Panel LED Pulse Output for energy pulsing and can be equipped with two optional Solid State Digital Outputs for kWh and kvarh pulsing, replacing the default Digital Outputs. Energy Pulse Outputs are typically used for accuracy testing. Energy Pulsing via the Front Panel LED can be enabled from the Front Panel through the LED EN Pulse setup parameter. The pulse constant can be configured as 1000/3200/6400 pulses per kWh/kvarh through the EN Pulse CNST setup parameter.

4.1.4 Analog Input

The PMC-53A-E comes optionally with an Analog Input which can be programmed as 0mA to 20mA or 4mA to 20mA input. There are 3 setup parameters:

Type: Select between 0-20mA or 4-20mA input. AI Zero: This value corresponds to the minimum Analog Input of 4 mA (for 4-20mA input) and

has a range of -999,999 to +999,999.

AI Full: This value corresponds to the maximum Analog Input of 20 mA and has a range of -

999,999 to +999,999. For example, to measure the oil temperature of a transformer, connect the outputs of the temperature sensor to the AI terminals of the PMC-53A-E. The temperature sensor outputs 4mA when the temperature is -25°C and 20mA when the temperature is 100°C. As such, the Type parameter should be programmed as 4-20mA. The AI FULL parameter should be programmed with the value 100, and the AI ZERO parameter should be programmed with the value -25. Therefore, when the output of the sensor is 20mA, the reading will be 100.00°C. When the output is 4mA, the reading will be -25.00°C. When the output is 12mA, the reading will be (100°C - (-25°C)) x (12mA-4mA) / (20mA-4mA) + (-25°C) = 37.50°C.

4.2 Power and Energy

4.2.1 Basic Measurements

The PMC-53A-E provides the following basic measurements which are available through the Front Panel or communications.

Table 4-2 Basic Measurements

Notes:

1) When the Wiring Mode is 3P3W, the per-phase Uln, kW, kvar, kVA and Power Factor are reserved.

2) The Frequency detection priority is: U1 (U12) > U2 (U23) > U3 (U31). For example, if U1=0, the U2 signal would be used for

Frequency detection instead. If both U1 and U2 are 0, the U3 signal would be used for Frequency detection.

Self-Read Time (Register: 6033)

The Self-Read Time allows the user to specify the time and day of the month for the Peak Demand Self-Read operation. The Self-Read Time supports three options:

 A zero value means that the Self-Read will take place at

00:00 of the first day of each month.

 A non-zero value means that the Self-Read will take

place at a specific time and day based on the formula: Self-Read Time = Day * 100 + Hour where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day of each month.

 A 0xFFFF value will disable the Self-Read operation and

replace it with manual operation. A manual reset will cause the Max. Demand of This Month to be transferred to the Max. Demand of Last Month and then reset. The terms This Month and Last Month will become Since Last Reset and Before Last Reset.

4.2.2 Energy Measurements

The PMC-53A-E provides Energy parameters for active energy (kWh), reactive energy (kvarh) and apparent energy (kVAh) with a resolution of 0.1 and a maximum value of ±99,999,999.9. When the maximum value is reached, the energy registers will automatically roll over to zero. The energy can be reset manually through the Front Panel or via communications. Further, the kWh/kvarh Import and Export for Per-Phase and Total, and the kVAh for Per-Phase and Total can be reset via communications.

The PMC-53A-E provides the following energy measurements:

Table 4-3 Energy Measurement

4.2.3 Interval Energy Measurements

The PMC-53A-E provides Interval Energy measurements of kWh Import/Export, kvar Import/Export and kVAh. The Interval Energy measurements represent the amount of energy consumed during the last completed interval as defined by EN Period. The Interval Energy Measurements can only be retrieved through communications and are not available on the Front Panel or Web Interface.

The Interval Energy Period (EN Period) setup parameter can be programmed from the Front Panel, Web Interface or through communications and allows the user to specify the interval for which the real-time energy consumption should be accumulated. Please note that changing the Interval Energy Period would clear the present Interval Energy measurements.

4.2.4 Demand Measurements

Demand is defined as the average power consumption over a fixed interval (usually 15 minutes) based on the Sliding Window method. The PMC-53A-E provides Present Demand and Predicted Demand for Ia, Ib, Ic, kW Total, kvar Total and kVA Total, updated once a second, as well as Max Demand for Ia, Ib, Ic, kW Total, kvar Total and kVA Total of TOU Tariff 1 to 8 in This Month (Since Last Reset) and Last Month (Before Last Reset). Only Import Demand is provided for kW Total, kvar total and kVA Total. Predicted Demand is typically used for pre-alarming and to help users reduce power consumption using a Setpoint to warn that the Demand limit may be exceeded.

The PMC-53A-E provides the following setup parameters:

4.3.1 Phase Angles

Phase analysis is used to identify the angle relationship between 3-phase Voltages and Currents. For WYE connected systems, the per phase difference of the Current and Voltage angles should

correspond to the per phase PF. For example, if the PF is 0.5 Lag and the Voltage phase angles are 0.0°,

240.0° and 120.0°, the Current phase angles should have the values of -60.0°, 180.0° and 60.0°.

4.3.2 Unbalance & Sequence Components

The same Self-Read Time for the Peak Demand Log is used to specify the time and day of the month for the Max/Min Self-Read operation. Please refer to Section 4.2.4 for a complete description of the Self-Read Time and its operation. The Max/Min Log of This Month can be reset manually via the Front Panel or via communications.

4.5.2 Peak Demand Log

The PMC-53A-E records the Peak Demand of This Month (Since Last Reset) and Last Month (Before Last Reset) with timestamp for Ia, Ib, Ic, kW Total, kvar Total and kVA Total as well as kW Total, kvar Total

and kVA Total for TOU Tariffs 1 to 8. The Peak Demand of This Month (Since Last Reset) can be accessed via the Front Panel and through communications while the Peak Demand of Last Month (Before Last Reset) only can be retrieved through communications. Please refer to Section 4.2.4 for a complete description of the Self-Read Time and its operation.

Table 4-10 Peak Demand Log

Notes:

1) When the wiring mode is 1P2W L-L or 1P2W L-N, the demand measurements for Phase B and C are invalid.

2) When the wiring mode is 1P3W, the demand measurements for Phase C are invalid.

4.5.3 Monthly Energy Log

The PMC-53A-E stores monthly energy data for the present month and the last 12 months. The Monthly Energy Log Self-read Time setup parameter allows the user to specify the time and day of the month

for the Recorder’s Self-read operation via communications. The Monthly Energy Logs are stored in the meter’s non-volatile memory and will not suffer any loss in the event of power failure, and they are stored on a First-In-First-Out basis where the newest log will overwrite the oldest.

The Monthly Energy Log Self-Read Time supports two options:

A zero value means that the Self-Read will take place at 00:00 of the first day of each month. A non-zero value means that the Self-Read will take place at a specific time and day based on the

formula: Energy Self-Read Time = Day x 100 + Hour where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day of each month. The Monthly Energy Logs can be reset manually through the front panel or via communications. The PMC-53A-E provides the following energy data for the present month and the last 12 months:

4.5.4 Daily and Monthly Freeze Log

The PMC-53A-E provides a Daily Freeze Log and a Monthly Freeze Log for Energy and Demand parameters and can store up to 60 daily freeze records (2 months) and 36 monthly freeze records (3 years). All Freeze Logs and their respective setup registers can only be accessed through communications. The PMC-53A-E’s Freeze Logs can freeze and record the following parameters:

Table 4-12 Freeze Log

The Daily Self-Read Time setup parameter allows the user to specify the time of the day for the Daily Freeze Log Self-Read operation, while the Monthly Self-Read Time setup parameter allows the user to specify the time and day of the month for the Monthly Freeze Log Self-Read operation.

1) Daily Freeze Self-Read Time can be set to a zero value or a non-zero value:

 A zero value means that the Self-Read will take place at 00:00 everyday.  A non-zero value means that the Self-Read will take place at a specific time of the day based on

the formula: Self-Read time = (Hour x 100 + Min) where 0 ≤ Hour ≤ 23 and 0 ≤ Min ≤ 59. For example, the value 1512 means that the Self-Read will take place at 15:12 of each day.

2) Monthly Freeze Self-Read Time can be set to a zero value or a non-zero value:

 A zero value means that the Self-Read will take place at 00:00 of the first day of each month.  A non-zero value means that the Self-Read will take place at a specific time and day based on

the formula: Monthly Self-Read Time = Day x 100 + Hour where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day of each month.

4.5.5 SOE Log

The PMC-53A-E’s SOE Log can store up to 100 events such as Power-on, Power-off, Digital Input status changes, Digital Output status changes, Setup changes and Setpoint events in its non-volatile memory. Each event record includes the event classification, its relevant parameter values and a timestamp in ±1 ms resolution. The SOE Log can be displayed on the Front Panel or Web Interface or retrieved via communications for display. If there are more than 100 events, the newest event will replace the oldest event on a First-In-First-Out basis. The SOE Log can be reset from the Front Panel or via communications.

4.5.6 Data Recorder (DR) Log

The PMC-53A-E provides five Data Recorders capable of recording a maximum of 16 parameters each with a minimum interval of 60s. The Data Recorder Log is stored in the device’s non-volatile memory and will not suffer any loss in the event of a power failure.

The PMC-53A-E’s 4MB log memory is divided equally into 5 buffers of 800kB each. By default, each DR is allocated one 800kB buffer, which can hold a maximum ~118 days of recording with 16 parameters at 15-minute interval. This is equivalent to having a Recording Depth of ~11,377 data records (~118 days x 24 hours per day x 4 data records per hour).

The Data Recorder can be configured to use more than one 800kB buffer if it’s required to maintain recording for a longer period of time. For example, if the entire 4MB log memory is used for a single Data Recorder, it can be configured to hold a maximum of 592 days (1.62 years) of recording with 16 parameters at 15-minute interval. This is equivalent to having a Recording Depth of 56,888 data records

(592 days x 24 hours per day x 4 data records per hour). In order to do this, it’s necessary to free the log memory occupied by Data Recorders #2 to #5 by setting their respective Number of Parameters and Recording Depth setup parameters to 0.

The PMC-53A-E’s Data Recorder has been enhanced such that it can support a maximum Recording Depth of 120,000 records (compared to the max. of 10,000 in PMC-53A), which is equivalent to 1250 days (~3.4 years) of recording at 15-minute interval. However, only one Data Recorder can be configured with a maximum of 6 parameters and 120,000 records.

The following formula can be used to calculate how many bytes would be required for a single record with n parameters where 0 ≤ n ≤ 16.

No. of Bytes per Record = n x 4 + Timestamp @ 8 bytes

With 16 parameters, the no. of bytes required = 16 x 4 + 8 = 72 bytes. If a Data Recorder is allocated a single 800kB buffer, its Recording Depth = 800kB / 72 bytes = 11,377 records.

It should be noted that the above calculation is used to illustrate the internal organization of the data storage and is only an approximation of the actual implementation. The following table defines how many records are actually available for the different number of parameters in each 800kB buffer.

The programming of the Data Recorder is only supported over communications. Each Data Recorder provides the following setup parameters:

Table 4-13 Setup Parameters for Data Recorder

The Data Recorder Log is only operational when the values of Trigger Mode, Recording Depth, Recording Interval, and Number of Parameters are all non-zero.

The Recording Offset parameter can be used to delay the recording by a fixed time from the Recording Interval. For example, if the Recording Interval parameter is set to 3600 (hourly) and the Recording Offset parameter is set to 300 (5 minutes), the recording will take place at 5 minutes after the hour

every hour, i.e. 00:05, 01:05, 02:05, etc. The value of the Recording Offset parameter should be less than the Recording Interval parameter.

4.6 Time of Use (TOU)

TOU is used for electricity pricing that varies depending on the time of day, day of week, and season. The TOU system allows the user to configure an electricity price schedule inside the PMC-53A-E and accumulate energy consumption into different TOU tariffs based on the time of consumption. TOU programming is only supported through communications.

The TOU feature on PMC-53A-E supports two TOU schedules, which can be switched at a pre-defined time. Each TOU schedule supports:

 Up to 12 seasons

Specify when to switch from one TOU schedule to another. Writing 0xFFFFFFFF to this parameter disables switching between TOU schedules.

Format: YYYYMMDDHH Default=0xFFFFFFFF

 90 Holidays or Alternate Days  20 Daily Profiles, each with 12 Periods in 15-minute interval  8 Tariffs

Instead of using the TOU schedule to switch between Tariffs, the PMC-53A-E supports Tariff switching based on the status of DI1 to DI3.

The 3 Digital Inputs (DI1, DI2 and DI3) represent 3 binary digits where Tariff 1=000, Tariff 2=001, Tariff 3= 010, …, Tariff 7=110 and Tariff 8=111 where DI1 represents the least significant digit and DI3 represents the most significant digit. As soon as DI1, DI2 and/or DI3 are configured as Tariff Switches, the current TOU Tariff will be determined by the status of the DIs, and the TOU Schedule will be ignored. The DI1 Function setup register must first be programmed as a Tariff Switch before configuring DI2 and DI3 with the same function. In other words, if DI1 is configured as a Digital Input or Energy Pulse Counter, and DI2 is configured as a Tariff Switch, the TOU will continue to function based on the TOU Schedule. The number of Tariffs supported depends on how many DIs are programmed as a Tariff Switch as indicated in the following table.

Table 4-14 DIs and the Number of Tariffs Setup

Each TOU schedule has the following setup parameters and can only be programmed via communications:

Table 4-15 TOU Setup Parameters

For each of the 8 Tariff Rates, the PMC-53A-E provides the following information: Energy: kWh Import/Export, kvarh Import/Export, kVAh for Per-Phase and Total Peak Demand: kW/kvar/kVA of This Month (Since Last Reset) and Last Month (Before Last Reset). TOU data is available through the Front Panel (excluding Peak Demand for Last Month) and

communications.

Table 4-17 SNTP Setup Parameters

4.7.2 SMTP

The PMC-53A-E can be configured to send Alarm Emails based on the Simple Mail Transfer Protocol (SMTP).

Table 4-18 SMTP Setup Parameters

Notes:

1) The SMTP Server’s IP Address, for example, 192.40.165.68, should be programmed into the Server IP setup parameter.

2) The default Sender’s email address is PMC-53A-E@foxmail.com.

3) The Password should not exceed 20 ASCII Characters.

4) The default Receiver’s email address is PMC-53A-E@163.com. Only one Receiver email address is supported.

5) Both the Sender and Receiver setup parameters should not exceed 36 ASCII characters.

Here is an example on how to configure a Setpoint to trigger an Alarm Email:

1. Click on Setup -> Comm. and configure the SMTP settings as shown below. Please note that all the

SMTP setup parameters should be entered correctly.

2. Click Save to store the configuration in the PMC-53A-E. The message “Successful” will appear if

the configuration is accepted by the meter. Then click Send as illustrated in the above figure. The message “Successful” will appear if a test email has been successfully sent to the Receiver, who should receive the following Test Email. However, if the “Successful” message is not displayed, it means that the test email has not been sent successfully because of incorrect configuration.

4.7.3 Ethernet Gateway

The PMC-53A-E’s Ethernet Gateway feature supports Modbus communications between the Master Software (e.g. PecStar iEMS) on a Local Area Network and other RS485-enabled devices (e.g. PMC-53A) via the PMC-53A-E’s Ethernet (P2) and RS485 port (P1). This eliminates the need for an additional, external Ethernet-to-RS485 Gateway, simplifies the overall network design and saves cost. The Master Software sends a “Modbus RTU over TCP/IP” packet (Modbus RTU packet, i.e. the payload, encapsulated in a TCP/IP frame) to the PMC-53A-E’s Ethernet port at its IP Address and IP Port No. 6000. The PMC53A-E receives this “Modbus RTU over TCP/IP” packet at its Ethernet port, extracts the “encapsulated” Modbus RTU packet, i.e. the payload, from the TCP/IP frame and then in turn forwards it to its RS485 port (P1). The RS485-enabled device receives the Modbus RTU packet and sends its response back to the PMC-53A-E, which in turn encapsulates the Modbus RTU response packet in a TCP/IP frame, sends it back to the Master Software over Ethernet and completes the transaction.

The following illustrates the steps of configuring the PMC-53AE’s Ethernet Gateway:

51

CET Electric Technology

1) Go to Setup-> Comm.-> RS485 (P1) to change the Protocol setup parameter from the default

setting of Modbus to Gateway, either via the Web Interface or Front Panel .

Figure 4-7 Select “Gateway” Mode on Web Server

2) Connect the RS485-enabled devices (i.e. PMC-53A) to the RS485 port (P1) of the PMC-53A-E.

Figure 4-8 Typical Application for Ethernet Gateway

3) Configure the Master Software (e.g. PecStar iEMS) on the WorkStation to communicate with

the RS485-enabled devices via PMC-53A-E’s Ethernet port at IP port No. 6000. It should be noted that the Master Software must support the Modbus RTU over TCP/IP protocol for this to work.

4) Make sure the serial port settings such as Baud Rate and Data Format are identical between

the PMC-53A-E’s RS485 port and the RS485-enabled devices.

5) The Master Software should be able to communicate with the RS485-enabled devices via the

PMC-53A-E’s Ethernet Gateway, providing that all the necessary configuration is correct.

4.8 Diagnostics

The PMC-53A-E provides wiring error detection for 3P4W and 3P3W wiring modes and allows the user to check for potential problems, especially during the initial commissioning stage. The following wiring errors may be detected:

 Frequency Out-of-Range  Voltage/Current Phase Loss  Incorrect Voltage and Current Phase Sequence  kW Direction per phase and Total  Possible Incorrect CT Polarity  Disconnection of Residual Current Input

Chapter 5 Modbus Register Map

This chapter provides a complete description of the Modbus register map (Protocol Version 1.0) for the PMC-53A-E to facilitate the development of 3rd party communications driver for accessing information on the PMC-53A-E. For a complete Modbus Protocol Specification, please visit http://www.modbus.org. The PMC-53A-E supports the following Modbus functions:

1) Read Holding Registers (Function Code 0x03)

2) Force Single Coil (Function Code 0x05)

3) Preset Multiple Registers (Function Code 0x10)

The following table provides a description of the different data formats used for the Modbus registers. The PMC-53A-E uses the Big Endian byte ordering system.

Notes:

1) I4, AI, Ir, DI Status and DO Status are only meaningful if the meter is equipped with the corresponding option.

2) For the DI Status register, the bit values of B0 to B3 represent the states of DI1 to DI4, respectively, with “1” meaning

Active (Closed) and “0” meaning Inactive (Open).

3) For the DO Status register, the bit values of B0 to B1 represent the states of DO1 and DO2, respectively, with “1”

meaning Active (Closed) and “0” meaning Inactive (Open).

4) For the Setpoint Status register, the bit values indicate the various Setpoint states with “1” meaning Active and “0”

meaning Inactive. The following table illustrates the details of the Alarm Status register.

Table 5-2 Setpoint Alarm Status Register

5) The following table illustrates the Wiring Diagnostic Status with 0 meaning Normal and 1 meaning Abnormal:

Table 5-3 Wiring Diagnostic Status Register

6) The PMC-53A-E has one SOE Log and five DR Logs. Each of these logs has a Log Pointer that indicates its current logging

position. The range of the Log Pointer is between 0 and 0xFFFFFFFF, and it is incremented by one for every new log generated and will roll over to 0 if its current value is 0xFFFFFFFF. A value of zero indicates that the SOE or DRx does not contain any Log. If a Clear Log is performed via communications, its Log Pointer will be reset to zero and immediately incremented by one with a new “Clear SOE via Communications” event. When the number of events is larger than the Log Depth, only the latest 100 SOE Logs (up to 120000 DR Logs) will be stored on a FIFO basis.

Use the following equation to determine the latest log location:

Latest Log Location = Modulo [Log Pointer/Log Depth] where Log Pointer may be one of the following: SOE Log Pointer, DR1 - DR5 Log Pointers and Log Depth is as follows:

SOE Log Depth = 100 (fixed)

7) The Device Operating Time means the accumulated Operating Time whenever any per-phase Current exceeds Current

Threshold of Device Operating Time (Register #6049). The Device Operating Time data is stored in non-volatile memory

and will not suffer any loss in the event of a power failure.

8) The range of the Log Pointer for Daily Freeze Log and Monthly Freeze Log is between 0 and 0xFFFF.

9) When the Wiring Mode is 1P2W L-N or 1P2W L-L, the L2 and L3 phase voltages and currents have no meaning, and their

registers are reserved.

10) When the Wiring Mode is 1P2W L-N, 1P2W L-L or 1P3W, the Sequence Components U1/I1, U2/I2 and U0/I0 have no

meaning and their registers are reserved.

DRx Log Depth = DRx Recording Depth (see Section 5.11.5 Data Recorder Setup)

5.2 Energy Measurements

The Energy registers have a maximum value of 999,999,999 and will roll over to zero automatically when it is reached. The actual energy value is 0.1 times of the register value.

Table 5-23 Monthly Energy Log

Notes:

1) This register represents the Month when it is read. To read the Monthly Energy Log, this register must be first written to

indicate to the device which log to load from memory. The range of this register is from 0 to 12, which represents the

Present Month and the Last 12 Months. For example, if the current month is 2016/10, “0” means 2016/10, “1” means 2016/09, “2” means 2016/08, etc., and ”12” means “2015/10”.

2) For each Monthly Energy Log, the time stamp shows the exact Self-Read Time (20YY/MM/DD HH:MM:SS) when the log

was recorded. For the Monthly Energy Log of the Present Month, the time stamp shows the current time of the meter because the Present Month is not yet over.

3) The Monthly Energy Log for the Present Month can be modified, but the Monthly Energy Logs for the Last 12 Months are

Read Only.

5.8 Daily and Monthly Freeze Logs

5.8.1 Daily Freeze Log

Table 5-24 Daily Freeze Log

Note:

1) Writing a value N between 1 and 60 to the Index register to retrieve the Daily Freeze Log of the Nth entry. For example,

writing 1 to the Index register will retrieve yesterday’s Daily Freeze Log. If N = 0 or N > 60, an exception response will be returned with the Illegal Data Value error code (0x03) as defined by the Modbus protocol. If all the returned values of the Nth Log Record (where 1 ≤ N ≤ 60) are all 0 (including the timestamp), this indicates that the returned Log Record is invalid and that the end of the Log has been reached. If the software is reading the Log for the very first time, it should start with N=1 and stop when either N=60 or when the returned Log Record is invalid. After that, all the software has to do is to read the Log on a daily basis with N=1.

Table 5-25 Monthly Freeze Log

Table 5-26 Demand Data Structure

Note:

1) Writing a value N between 1 and 36 to the Index register to retrieve the Monthly Freeze Log of the Nth entry. For example,

writing 1 to the Index register will retrieve last month’s Monthly Freeze Log. If N = 0 or N > 36, an exception response will be returned with the Illegal Data Value error code (0x03) as defined by the Modbus protocol. If all the returned values of the Nth Log Record (where 1 ≤ N ≤ 36) are all 0 (including the timestamp), this indicates that the returned Log Record is invalid and that the end of the Log has been reached. If the software is reading the Log for the very first time, it should start with N=1 and stop when either N=36 or when the returned Log Record is invalid. After that, all the software has to do is to read the Log on a monthly basis with N=1.

5.9 SOE Log

The SOE Log Pointer points to the register address within the SOE Log where the next event will be stored. The following formula is used to determine the register address of the most recent SOE event referenced by the SOE Log Pointer value:

Register Address = 10000 + Modulo[SOE Log Pointer-1/100]*8

where I1 represents the RMS value of the fundamental component, and In represents the RMS value for the nth harmonic with n for harmonic order.

THDr:

THDr=

where In represents the RMS value for the nth harmonic with n for harmonic order.

3) The Self-Read Time applies to both the Peak Demand Log as well as the Max/Min Log and supports the following three

options:

 A zero value means that the Self-Read will take place at 00:00 of the first day of each month.  A non-zero value means that the Self-Read will take place at a specific time and day based on the formula: Self-Read

Time = (Day x 100 + Hour) where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the SelfRead will take place at 12:00pm on the 15th day of each month.

 A 0xFFFF value means the automatic self-read operation is disabled and the log will be transferred manually.

4) The Self-Read Time applies to the Monthly Energy Log supports the following two options:

 A zero value means that the Self-Read will take place at 00:00 of the first day of each month.  A non-zero value means that the Self-Read will take place at a specific time and day based on the formula: Self-Read

Time = (Day x 100 + Hour) where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the SelfRead will take place at 12:00pm on the 15th day of each month.

5) The Delimiter setup register supports two options, 1 and 2:

Option 1: “,” is used as the x1000 delimiter and “.” as the decimal point (e.g. 123,456,789.0).

6) The Monthly Freeze Self-Read Time supports only two options:

7) The Daily Freeze Self-Read Time can be set to a zero value or a non-zero value:

8) The following table illustrates the parameters that can be selected for display in the Default Display screen.

Option 2: “ ” is used as the x1000 delimiter and “,” as the decimal point (e.g. 123 456 789,0).

 A zero value means that the Self-Read will take place at 00:00 of the first day of each month.  A non-zero value means that the Self-Read will take place at a specific time and day based on the formula: Self-Read

Time = Day * 100 + Hour where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day of each month.

 A zero value means that the Self-Read will take place at 00:00 everyday.  A non-zero value means that the Self-Read will take place at a specific time of the day based on the formula: Self-Read

time = (Hour x 100 + Min) where 0 ≤ Hour ≤ 23 and 0 ≤ Min ≤ 59. For example, the value 1512 means that the SelfRead will take place at 15:12 of each day.

Table 5-34 Default Display Parameters

9) The Interval Energy will be reset once the EN Period is changed.

10) The DNP Rolling Polling Objects are list in table below:

Table 5-35 DNP Polling Objects

11) SNTP doesn’t support Daylight Saving Time (DST). The following table lists the supported Time Zones:

Table 5-36 Time Zones

12) The SNTP Sync. Interval should be set between 10 and 1440 minutes.

13) This string register specifies the sender email address that appears in the “From” field of the email. This string may be up to

35 characters long. Please add the value zero “0000” at the end of the string as the string terminator. For example, the default email address is PMC-53A-E@foxmail.com, set the registers as” 0050 004D 0043 002D 0035 0033 0041 002D 0045 0040 0066 006F 0078 006D 0061 0069 006C 002E 0063 006F 006D 0000”.

14) This string register specifies the Logon Password to login the “Sender Email” account. This string may be up to 19 characters

long. Please add the value zero “0000” at the end of the string as the string terminator. For example, if the password is “PMC-53A-E”, set the registers as “0050 004D 0043 002D 0035 0033 0041 002D 0045 0000”

15) This string register specifies the destination email address that appears in the “To” field of the email. This string may be up

to 35 characters long. Please add the value zero “0000” at the end of the string as the string terminator. For example, if the email address is PMC-53A-E@gmail.com, so set the registers as” 0050 004D 0043 002D 0035 0033 0041 002D 0045 0040 0067 006D 0061 0069 006C 002E 0063 006F 006D 0000”.

Notes:

1) Changing any of these Data Recorder setup registers will reset the Data Recorder.

2) Recording Offset can be used to delay the recording by a fixed amount of time from the Recording Interval. For example,

if the Recording Interval is set to 3600 (hourly) and the Recording Offset is set to 300 (5 minutes), the recording will take place at 5 minutes after the hour every hour, i.e. 00:05, 01:05, 02:05, etc. Thus Recording Offset < Recording Interval.

5.12 TOU Setup

5.12.1 Basic

Notes:

1) If DI1 is not programmed as a Tariff Switch, the TOU will function based on the TOU Schedule. The number of Tariffs

supported depends on how many DIs are programmed as a Tariff Switch as indicated in Section 4.6.

2) The following table illustrates the data structure for the TOU Switch Time. For example, 0x1003140C indicates a switch time

of 12:00pm on March 20th, 2016. Writing 0xFFFFFFFF to this register disables the switching between TOU Schedule.

5.12.2 Season

The PMC-53A-E has two sets of Season setup parameters, one for each TOU. The Base Addresses for the two sets are 7100 and 8100, respectively, where the Register Address = Base Address + Offset. For example, the register address for TOU #1’s Season #2’s Start Date is 7100+4 = 7104. Moreover, all the registers in the same set of Season should be written in the identical frame.

5.12.4 Alternate Days

Each Alternate Day is assigned a Daily Profile and has a higher priority than Season. If a particular date is set as an Alternate Day, its assigned Daily Profile will override the “normal” Daily Profile for this day according the TOU settings.

The PMC-53A-E has two sets of Alternate Days setup parameters, one for each TOU. The Base Addresses for the two sets are 7700 and 8700, respectively, where the Register Address = Base Address + Offset. For example, the register address for TOU #2’s Alternative Day #2’s Date is 8700+3 = 8703.

Table 5-50 Alternate Days Setup

Note:

1) The following table illustrates the data structure of the Date register:

Table 5-51 Date Format

When the Year and/or Month are set as 0xFF, it means the Alternate Day is repetitive by year and/or month, i.e. the same day of every year or every month is an Alternate Day.

5.13 Time

There are two sets of Time registers supported by the PMC-53A-E – Year / Month / Day / Hour / Minute

/ Second (Registers # 60000 to 60002) and UNIX Time (Register # 60004). When sending time to the PMC-53A-E over Modbus communications, care should be taken to only write one of the two Time register sets. All registers within a Time register set must be written in a single transaction. If registers 60000 to 60004 are being written to at the same time, both Time register sets will be updated to reflect the new time specified in the UNIX Time register set (60004) and the time specified in registers 6000060002 will be ignored. Writing to the Millisecond register (60003) is optional during a Time Set operation. When broadcasting time, the function code must be set to 0x10 (Pre-set Multiple Registers). Incorrect date or time values will be rejected by the meter. In addition, attempting to write a Time value less than Jan 1, 2000 00:00:00 will be rejected.

Table 5-52 Time Registers

Note:

1) The UNIX time in GMT+00:00 Time Zone should be used when writing the meter’s time. The meter will compute internally

and display in Local Time based on the setting of the Time Zone setup register (#6053).

5.14 Remote Control

The DO Control registers are implemented as both “Write-Only” Modbus Coil Registers (0XXXXX) and Modbus Holding Registers (4XXXXX), which can be controlled with the Force Single Coil command (Function Code 0x05) or the Preset Multiple Hold Registers (Function Code 0x10). The PMC-53A-E does not support the Read Coils command (Function Code 0x01) because DO Control registers are “WriteOnly”. The DO Status register 0098 should be read instead to determine the current DO status.

The PMC-53A-E adopts the ARM before EXECUTE operation for the remote control of its Digital Outputs if this function is enabled through the Arm Before Execute Enable Setup register (6032), which is disabled by default. Before executing an OPEN or CLOSE command on a Digital Output, it must be “Armed” first. This is achieved by writing the value 0xFF00 to the appropriate register to “Arm” a particular DO operation. The DO will be “Disarmed” automatically if an “Execute” command is not received within 15 seconds after it has been “Armed”. If an “Execute” command is received without first having received an “Arm” command, the meter ignores the “Execute” command and returns the 0x04 exception code.

*There are no unit types for kvarh and kVAh in BACnet so the return values are in unit of kWh.

Notes:

1) When the Wiring Mode is 3P3W, the per phase line-to-neutral voltages, kWs, kvars, kVAs and

PFs have no meaning, and their registers are reserved.

2) Uan/Ubn/Ucn THD = Uab/Ubc/Uca THD in 3P3W Wiring Mode and represent the harmonics

of the line voltages.

3) Uan/Ubn/Ucn Angle = Uab/Ubc/Uca Angle in 3P3W Wiring Mode and represent the phase

angles of the line voltages.

4) Analog Value Objects (PMC-53A-E’s Basic Setup Registers)

Optional Properties Supported: Description, Relinquish_Default, Priority_Array Writable Properties: Present_Value, Out_Of_Service, Units, Relinquish_Default

Use the Present Value property of the Analog Value object for some writable variables in the meter other than those used specifically for BACnet configuration or Time Synchronization. Values are checked when written, and errors are returned for invalid entries. The table below describes how the Setup Registers of the PMC-53A-E are represented in BACnet, their valid ranges, their defaults as well as how they are used. PMC-53A-E supports the Description, Relinquish_Default and Priority_Array optional properties. Writable properties include Present_Value, Out_Of_Service, Units and Relinquish_Default, but Units are not non-volatile after modification.

#

PT Primary / PT Secondary Must be less than 10000.

5) Binary Input Objects (PMC-53A-E’s Digital Inputs)

Optional Properties Supported: Description, Reliability

Use the Present_Value properties of the Binary_Input objects as alerts for conditions of potential concern regarding system measurements. These objects support the Description and Reliability optional properties and all required Binary_Input object properties. None of them are writable.

6) Binary Output Objects (PMC-53A-E’s Digital Outputs)

Optional Properties Supported: Inactive_Text, Active_Text

Use the Present_Value property of the Binary_Output objects as alerts for DO conditions. Reading Binary_Output objects have the highest priority. PMC-53A-E supports Inactive_Text, Active_Text optional properties and all required Binary_Output object properties. Present_Value, Out_Of_Service and Polarity properties can be written, but these are non-volatile after modification. The Present_Value can only be written when the Out_Of_Service is true to change the state of the Digital Output and will be written as W when the Out_Of_Service is false.
