2.5 Wiring Connections

The PMC-512-A provides 12 Current Inputs which can be configured as 12x1-Ø SM, 4x3-Ø SM or a

combination of 1-Ø SMs or 3-Ø SMs. Regardless of the Wiring Mode, the PMC-512-A always relies on

the relationship illustrated in Table 2-2 between Voltage Inputs (V1, V2, V3) and Current Inputs (I1 – I12)

for its Power and Energy calculations for the various 1-Ø and 3-Ø SMs. 2-Ø SM (or 1P3W Wiring Mode)

is not supported by the PMC-512-A. The SM assignment principle is not programmable. Therefore, it is

extremely important to allocate the 1-Ø and 3-Ø circuits during installation that meet this fixed

assignment principle.

2.5.4 Communications Wiring

The PMC-512-A provides two standard RS485 ports and supports the Modbus RTU protocol. Up to 32

devices can be connected on each RS485 bus. The overall length of the RS485 cable connecting all

devices should not exceed 1200m.

If the master station does not have a RS485 communications port, a RS232/RS485 or USB/RS485

converter with optically isolated output and surge protection should be used.

If the RS485 bus is very long and approaches the 1200m limit as defined by the standard, it’s

recommended that a 120Ω termination resistor be added to the end of the RS485 cable (but only on

one end) to improve the communication reliability

Notes:

1) The Dmd S.R. Time and Mthly Freeze Time support the following two options: a. A zero value means that the Self-Read will take place at 00:00 of the first day of each month. b. 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 Self-

Read will take place at 12:00pm on the 15th day of each month.

Notes:

1) If the BLTO is set to 0, the Time Out is disabled, which means that the Backlight will always be on.

2) Auto-Scroll Setup allows users to select which 1-Ø SM, 3-Ø SM or VM would be displayed in Auto-Scroll Mode. For example,

if the PMC-512-A is used to monitor three 3-Ø circuits with I1 to I9, three 1-Ø circuits with I10 to I12 and without any virtual

metering, the 1-Ø SM1 to SM9, 3-Ø SM4 as well as VM1 to VM4 can be disabled in the Auto-Scroll Mode to prevent un-

necessary information from being displayed and thus simplifying the HMI access. The Parameter Categories and their

measurements are listed in the table below, and all of them are Enabled in Auto-Scroll Mode by default. The Parameter

Category U (Voltage) is always shown and cannot be disabled in Auto-Scroll mode.

4.1.2 Analog Input

The PMC-512-A comes standard with an Analog Input which can be programmed as 0mA to 20mA or

4mA to 20mA input. There are 3 setup parameters:

Setup Parameter

Definition

Options/Default*

AI Type

Select between 0-20mA or 4-20mA input.

0 = 4-20mA*

1 = 0-20mA

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.

-999,999 to +999,999 Default=400

AI Full

This value corresponds to the maximum Analog Input of 20 mA and has a range of -999,999 to +999,999.

-999,999 to +999,999

Default=2000

Table 4-2 AI Setup Parameters

For example, to measure the oil temperature of a transformer, connect the outputs of the temperature

sensor to the AI terminals of the PMC-512-A. 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.

4.1.3 Energy Pulse Outputs

The PMC-512-A comes standard with one front panel LED Pulse Output for kWh/kvarh pulsing. Energy

pulsing mode can be programmed from the Front Panel or through communications via the LED EN

Pulse setup parameter. Energy Pulse Outputs are typically used for accuracy testing. The pulse constant

can be configured as 1/10/100/400/1000/3200 imp/kxh (kWh/kvarh). However, it’s recommended that

the pulse constant should be set based on the CT specifications:

Table 4-3 Recommended Pulse Constant

Notes:

1) For 5A CT, the recommended Energy Pulse Constant is 3200 imp/kxh if it is directly connected to the system. Otherwise,

the Energy Pulse Constant should be set based on the primary rating of the external CT. For example, if the primary rating of the external CT is 100A, then it is recommended to set the Energy Pulse Constant to 400 imp/kxh.

4.2.2 Energy Measurements

The PMC-512-A provides Energy parameters for active energy (kWh), reactive energy (kvarh) and

apparent energy (kVAh) with a resolution of 0.01 and a maximum value of 1,000,000.00. When the

maximum value is reached, the energy registers will automatically roll over to zero. The energy registers

can be reset manually through communications for all SMs.

The PMC-512-A provides the following energy measurements:

 1-Ø SMs: kWh Import/Export, kvarh Import/Export, kVAh  3-Ø SMs: kWh Import/Export Total, kvarh Import/Export Total, kVAh Total  VMs: kWh Import/Export, kvarh Import/Export, kVAh

4.2.3 Interval Energy Measurements

The PMC-512-A provides Interval Energy measurements of kWh Import/Export, kvarh Import/Export

and kVAh for 1-Ø SMs and VMs, kWh Import/Export total, kvarh Import/Export total and kVAh for 3-Ø

SMs. The Interval Energy registers can only be retrieved through communications.

The Interval Energy Period setup parameter can be programmed from the Front Panel or through

communications and allows the user to specify the latest interval for which real-time energy

consumption should be recorded. Please note that changing Interval Energy Period would clear the

present Interval Energy measurements.

4.2.4 Demands

Demand is defined as the average power consumption over a fixed interval (usually 15 minutes) based

on the sliding window method. The PMC-512-A provides Present Demand of Current for 1-Ø SMs and

Present Demand of kW, kvar and kVA for 1-Ø SMs, 3-Ø SMs as well as VMs.

The PMC-512-A provides the following Demand setup parameters:

Self-Read Time

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 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 Self-

Read will take place at 12:00pm on the 15th day of each month.

4.3 Alarm Setpoints

The PMC-512-A provides powerful alarming functions for the 1-Ø SMs, 3-Ø SMs as well as for different

parameters. Each Alarm Type can be independently enabled, and a particular alarm within each Alarm

Type may also be disabled individually by setting its Alarm Threshold to 0.

4.3.1 Alarm Status

The PMC-512-A supports both Instantaneous Alarm and Latched Alarm, which are defined below.

Instantaneous Alarm

The status of an Instantaneous Alarm becomes active when the alarm condition is met and is

automatically reset to NORMAL when the alarm condition is no longer met. Instantaneous Alarm cannot

be reset manually.

Latched Alarm

On the other hand, the status of a Latched Alarm becomes Active when the alarm condition is met and

will remain in the Active state even after the alarm condition is no longer met. The Latched Alarm must

be reset manually. However, the Latched Alarm cannot be reset while the alarm condition remains

active.

Table 4-6 Global Parameters

The Universal Hysteresis is a global parameter that is used to prevent measurement fluctuation around

the threshold point from causing an alarm to fluctuate between the Active and Inactive states.

It should be noted that the absolute value of the Alarm Threshold is calculated based on the Breaker

Rating parameters. Therefore, it’s critical to set the Breaker Rating correctly for each Current channel

for the Current Alarms to work properly.

| Channel Alarm Threshold | = Channel’s Breaker Rating x Alarm Threshold (%)

For Current On, High and High-High Alarms, which are conceptually similar to Over Setpoint:

Return Threshold = Alarm Threshold x (1 – Universal Hysteresis)

For Low and Low-Low Alarms, which are conceptually similar to Under Setpoint:

Return Threshold = Alarm Threshold x (1 + Universal Hysteresis)

The PMC-512-A provides the ON/OFF status for each Current channel to indicate whether the channel

is ON (Loaded) or OFF (No Load). If the Channel status is OFF, it means that the channel has no load and

would prevent the Low and Low-Low alarms from activating.

The following figures illustrate the logic diagram of the Current ON/OFF status, respectively.

4.3.3 Current Alarms

PMC-512-A provides the Current On/OFF status as well as four Current Alarm Levels (High-High, High,

Low and Low-Low) for the 12x1-Ø SM. The Current Alarms will only be evaluated if it’s determined that

the Current ON status is true.

It should be noted that the absolute value of the Alarm Threshold is calculated based on the Breaker

Rating parameters. Therefore, it’s critical to set the Breaker Rating correctly for each Current channel

for the Current Alarms to work properly.

| Channel Alarm Threshold | = Channel’s Breaker Rating x Alarm Threshold (%)

4.4.1 Phase Angles

The PMC-512-A provides Voltage and Current Phase Angle measurements for 1-Ø SMs and 3-Ø SMs.

Phase analysis is used to identify the angle relationship between 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 power factor 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°.

aggregation from any of the 12 individual 1-Ø SMs, please refer to Section 5.8.7 VM Setup for more

information.

Each VM provides the following parameters kW Total, kvar Total, kVA Total, kWh Import/Export Total,

kvarh Import/Export Total and kVAh. VM’s energy measurements are separated from the SM’s energy

measurements so clearing the energy measurements of one SM would not affect the energy

measurements of the VM that consists of that particular SM.

4.7 Data Logging

4.7.1 Peak Demand Log

The PMC-512-A records the Peak Demand of This Month (Since Last Reset) and Last Month (Before

Last Reset) with timestamp for Current for 1-Ø SMs as well as kW, kvar and kVA for 1-Ø SMs, 3-Ø SMs

and VMs. All Demand and Peak Demand information except for VMs can be accessed via the front panel

or through communications. Please refer to Section 4.2.4 for a complete description of the Self-Read

Time and its operation. The Peak Demand Log of a certain SM or VM can be reset through the optional

HMI Display or via communications.

SMs and VMs for the last 1000 days. The Daily Freeze Log is 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 (FIFO)

basis where the newest log will overwrite the oldest. The Daily Freeze Logs can only be accessed through

communications and contain the following parameters:

Circuits

Parameters

1-Ø SMs

Current, kW, kvar, kVA, kWh/kvarh Import, kWh/kvarh Export, kVAh Total

3-Ø SMs

kW Total, kvar Total, kVA Total, kWh/kvarh Import, kWh/kvarh Export, kVAh Total

VMs

kWh/kvarh Import, kWh/kvarh Export, kVAh Total

Table 4-18 Freeze Log

The Daily Freeze Log’s Self-Read operation will take place at 00:00 every day. If there are more than

1000 logs, the newest log will replace the oldest log on a FIFO basis.

4.7.4 Monthly Freeze Log

The PMC-512-A provides a Monthly Freeze Log of Energy parameters for 1-Ø SMs, 3-Ø SMs and VMs

for the last 24 months. The Monthly Freeze Log is 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 FIFO basis where the newest

log will overwrite the oldest. The Monthly Freeze Logs can be reset manually via the front panel or

through communications.

The Monthly Freeze Log Self-read Time setup parameter allows the user to specify the time and day of

the month for the Self-read operation and 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: 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 PMC-512-A’s Monthly Freeze Log can only accessed through communications and contains the

following parameters:

Circuits

Parameters

1-Ø SMs

kWh/kvarh Import, kWh/kvarh Export, kVAh

3-Ø SMs

kWh/kvarh Total Import, kWh/kvarh Total Export, kVAh Total

VMs

4.7.5 Data Recorder Log (DR Log)

The PMC-512-A provides one DR capable of recording a maximum 60 parameters. The DR Log is stored

in the meter’s non-volatile memory and will not suffer any loss in the event of a power failure.

47

CET Electric Technology

The programming of the DR is only supported over communications. The DR provides the following

setup parameters:

Setup Parameters

Value/Option

Default

Trigger Mode

0=Disabled / 1=Enabled

0

Recording Mode

0=Stop-When-Full / 1=First-In-First-Out

1

Recording Depth

1 to 5000 (entry)

5000

Recording Interval

60 to 345,600 seconds

900 s

Recording Offset

0 to 43,200 seconds, 0 indicates no offset.

0

Number of Parameters

0 to 60

55

Parameter 1 to 60

See Appendix B

Table 4-20 Setup Parameters for Data Recorder

Notes:

1) The DR Log is only operational when the values of Trigger Mode, Recording Depth, Recording Interval, and Number of

Parameters are all non-zero.

2) 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 must be less than the Recording Interval parameter.

Chapter 5 Modbus Register Map

This chapter provides a complete description of the Modbus register map (Protocol Versions 2.1) for

the PMC-512-A to facilitate the development of 3rd party communications driver for accessing

information on the PMC-512-A. For a complete Modbus Protocol Specification, please visit

www.modbus.org.

The PMC-512-A 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)

4) Read Energy Files (Function Code 0x14)

The following table provides a description of the different data formats used for the Modbus registers.

The PMC-512-A uses the Big Endian byte ordering system.

Notes:

1) For the DI Status register, the bit values of Bit 0 to Bit 11 represent the states of DI1 to DI12, respectively, with “1” meaning

Active (Closed) and “0” meaning Inactive (Open). The remaining bits are reserved.

2) For the DO Status register, the bit value of Bit 0 represents the state of the DO, with “1” meaning Active (Closed) and “0”

meaning Inactive (Open). The remaining bits are reserved.

3) The Diagnostics register indicates the various system statuses with a bit value of 0 meaning Normal and 1 meaning Abnormal.

The following table illustrates the details of the Diagnostics register.

Table 5-2 Diagnostics Register (Reg. # 0002)

4) The range of the SOE, Daily Freeze, DR, and Monthly Freeze Log Pointer is between 0 and 0xFFFFFFFFH. The pointer is

incremented by one for every new log generated and will roll over to 0 if its current value is 0xFFFFFFFFH. A value of zero

indicates that the specific Log does not contain any record. If a Clear Log is performed from the Front Panel or via

communications, its Log Pointer will be reset to zero. Use the following equation to determine the latest log location:

Latest Log Location = Modulo [SOE Pointer / Log Depth]

49

CET Electric Technology

where Log Depth = 512 for SOE Log, 1000 for Daily Freeze Log, 24 for Monthly Freeze Log and DR’s Recording Depth

for the DR Log.

Table 5-36 Daily Freeze Log

Notes:

1) There is no Log Pointer that indicates the current logging position. Writing a value between 1 and 1000 to the Index register

to retrieve the Daily Freeze Log of the Nth entry. For example, writing 1 to the Index register will retrieve the first day’s Daily

Freeze Log. If N = 0 or N > 1000, 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 N

th

Log Record (where 1 ≤ N ≤ 1000) 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

th

and stop when either N=1 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 Nth.

Notes:

1) The value of [PT Primary/PT Secondary] cannot exceed 10000.

2) The Self-Read Time applies to both the Peak Demand Log as well as the Monthly Freeze Log and supports the following

two options:

a) A zero value means that the Self-Read will take place at 00:00 of the first day of each month. b) 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 Self-

Read will take place at 12:00pm on the 15th day of each month.

5.9 Time Registers

There are two sets of Time registers supported by the PMC-PMC-512-A – Year / Month / Day / Hour /

Minute / Second (Registers # 60000 to 60002) and UNIX Time (Register # 60004). When sending time to

the PMC-512-A 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 60000-

60002 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

71

CET Electric Technology

Jan 1, 2000 00:00:00 will be rejected.

5.11 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-512-A does

72

CET Electric Technology

not support the Read Coils command (Function Code 0x01) because DO Control registers are “Write-

Only”.

The PMC-512-A 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 (6014), 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.
