4.1 Inputs and Outputs

4.1.1 Digital Inputs

The PMC-660 comes standard with six self-excited Digital Inputs that are internally wetted at 24 VDC

with a sampling frequency of 1000Hz and programmable debounce. The PMC-660 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 counting is supported with programmable pulse weight and

facilitates WAGES (Water, Air, Gas, Electricity and Steam)

information collection.

3) Demand Sync Pulse One of the Digital Inputs can be programmed to receive Demand

Sync Pulse. Please refer to Section 4.2.5 for a detailed description.

4) Time Synchronization The Digital Inputs can be used as external time synchronization

pulse. Please refer to Section 4.8 for a detailed description.

5) 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 to 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. This feature is

available in Firmware V2.00.00 or later.

The following table describes the DI’s setup parameters:

33

Table 4-1 DI Setup Parameters

CET Electric Technology

4.1.2 Digital Outputs

The PMC-660 comes standard with three Form A Electromechanical Digital Outputs. Digital Outputs are

normally used for setpoint alarming, load control, or remote control applications.

Digital Outputs on the PMC-660 can be used in the following applications:

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

setup parameter in Section 3.4.3 for a detailed description.

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

software or the PecStar® iEMS Integrated Energy Management

System.

3) Control Setpoint Control setpoints can be programmed to trigger DO, Data Recorder,

Waveform Recorder or Alarm Email upon becoming active. Please

refer to Section 4.4 for a detailed description.

4) Logical Module Logical Module can be programmed to trigger DO, Data Recorder or

Waveform Recorder upon becoming active. Please refer to Section

4.5 for a detailed description.

5) Dip/Swell Setpoint Dip/Swell setpoint can be programmed to trigger DO, Data Recorder,

Waveform Recorder or Alarm Email upon becoming active. Please

refer to Section 4.3.5 for a detailed description.

6) Transient Setpoint: Transient setpoint can be programmed to trigger DO, Data Recorder,

Waveform Recorder or Alarm Email upon becoming active. Please

refer to Section 4.3.6 for a detailed description.

Since there are multiple ways to trigger the Digital Outputs on the PMC-660, 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 applications. Remote Control, Control Setpoint, Logical

Module, Dip/Swell Setpoint and Transient 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-660 comes standard with two Front Panel LED Pulse Outputs for kWh and kvarh pulsing.

Energy Pulse Outputs are typically used for accuracy testing. Energy pulsing can be enabled from the

Front Panel through the EN PULSE setup parameter. The pulse constant can be configured as

1000/3200/5000/6400/12800 pulses per kWh or kvarh through the EN CONST setup parameters. The

pulse width is fixed at 80ms.

4.1.4 Analog Input

The PMC-660 comes optionally with an Analog Input which can be programmed as 0mA to 20mA or

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

34

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

AI Zero: This value corresponds to the minimum Analog Input of 0 mA (for 0-20mA input) or 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-660. 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.

4.1.5 Analog Output

The PMC-660 comes optionally with one Analog Output which can be programmed as 0mA to 20mA or

4mA to 20mA output. There are 4 setup parameters:

Type: Select between 0-20mA or 4-20mA output.

AO Zero: Defines the zero scale value of the parameter when the Analog Output is 0 mA (for 0-

20mA output) or 4 mA (for 4-20mA output). The value ranges between -999,999 to

+999,999.

AO Full: Defines the full scale value of the parameter when the Analog Output is 20 mA. The

value ranges between -999,999 and +999,999.

Key: Defines the parameter to which the Analog Output is proportional. The Analog Output

Parameters are listed in Table 3-7.

For example, an AO of 4-20mA is required to be proportional to Phase A current. The maximum value

of phase A current is 2000A, and the minimum value is 500A. As such, the Type parameter should be

programmed as 4-20mA. The Key parameter should be programmed with Ia (Phase A Current). The AO

FULL parameter should be programmed with the value 2000. The AO ZERO parameter should be

programmed with the value 500. Therefore, when Phase A Current is 500A or below, the AO output is

4mA. When Phase A Current is 2000A, the AO output is 20mA. When Phase A Current is 1250A, the AO

is (1250A-500A) x (20mA-4mA) / (2000A-500A) + 4mA = 12.00(mA).

The PMC-660 provides Interval Energy measurements of kWh Import/Export, kvar Import/Export and

kVAh since Firmware V2.00.00. 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.

The Interval Energy Period (EN Period) setup parameter can be programmed 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 High-speed Measurements

The PMC-660 provides the following high-speed measurements which are available through the Front

Panel or communications.

 3-Phase Voltage with ½ cycle update rate
 3-Phase Current, Neutral Current (I4) and I0 with 1 cycle update rate
 3-Phase Power and Power Factor with 1 cycle update rate

4.2.5 Demand Measurements

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

on the sliding window method. 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-

660 provides the following 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 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 Peak Demand of This Month to be transferred
to the Peak Demand of Last Month and then reset. The
terms This Month and Last Month will become Since Last
Reset and Before Last Reset.

4.6.3 Interval Energy Recorder (IER) Log

The PMC-660 provides an Interval Energy Recorder capable of recording the interval energy

consumption for kWh/kvarh Import/Export and kVAh. If the users wish to record the accumulative

energy values instead of the interval energy consumption, the Data Recorder function should be used

in the PMC-660. The recorded data is stored in the device’s non-volatile memory and will not suffer any

loss in the event of power failure.

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

setup parameters:

Table 4-19 IER Setup Parameters

The IER is only operational when the values of Recording Mode, Recording Depth, Start Time and

Number of Parameters are all non-zero. When the present time meets or exceeds the “Start Time”, the

IER will start to record.

4.6.4 Waveform Recorder (WFR) Log

The PMC-660 provides 2 independent groups of Waveform Recorders (WFR) with a combined total of

32 entries. Each WFR can simultaneously capture 3-phase Voltage and Current signals at a maximum

resolution of 256 samples per cycles. The WFR can be triggered by Setpoints, Dip/Swell and Transient

Detection or manually through communications. The manual trigger command has a higher priority.

When the WFR is already in progress, other WFR commands will be ignored until the current recording

has completed. The WFR Log has a capacity of 32 entries organized in a First-In-First-Out basis, with the

newest WFR log replacing the oldest one. The waveform data is stored in the device’s non-volatile

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

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

setup parameters:

The WFR logs can be retrieved via communications by our PecStar® iEMS or our free PMC Setup

Software for display.

Figure 4-3 WFR Log displayed in PecStar®

4.6.5 PQ Log

The PMC-660’s PQ Log can store up to 1000 PQ events such as Dips/Swells and Transients. Each event

record includes the event classification, its relevant voltage values and a timestamp in 1ms resolution.

All events can be retrieved via communications for display. If there are more than 1000 events, the

newest event will replace the oldest event on a First-In-First-Out basis. The PQ Log can be reset from

the Front Panel or via communications.

4.6.6 SOE Log

The PMC-660’s SOE Log can store up to 512 events such as Power-on, Power-off, Setpoint actions, Relay

actions, Digital Input status changes and setup changes in its non-volatile memory. Each event record

includes the event classification, its relevant parameter values and a timestamp in 1ms resolution. All

events can be retrieved via communications for display. If there are more than 512 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.

4.6.7 Data Recorder (DR) Log

The PMC-660 comes equipped with 4MB of memory and provides 4 High-Speed Data Recorders (HS DR)

as well as 12 Standard Data Recorders (DR) capable of recording 16 parameters each. The recorded data

is stored in the device’s non-volatile memory and will not suffer any loss in the event of power failure.

The DR Log is only operational when the values of Triggered Mode, Recording Mode, Recording Depth,

Recording Interval, and Number of Parameters are all non-zero.

Data Recorder #X can be triggered by clearing the Data Recorder #X when it is full in Stop-When-Full

mode (See Section 5.8.9).

For Standard Data Recorder, 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 programmed value of the

Recording Offset parameter should be less than that of the Recording Interval parameter.

For High-speed Data Recorder, the Recording Offset should be set to zero.

4.7 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-660 and

accumulate energy consumption into different TOU tariffs based on the time of consumption. TOU

programming is only supported through communications. This feature is available in Firmware V2.00.00

or later.

The TOU feature on PMC-660 supports two TOU schedules, which can be switched at a pre-defined time.

Each TOU schedule supports:

 Up to 12 seasons
 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-660 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.

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

communications:

Table 4-23 TOU Setup Parameters

For each of the 8 Tariff Rates, the PMC-660 provides the following Energy measurements: kWh

Import/Export, kvarh Import/Export, kVAh.

T1-T8’s kWh Import/Export are available through the Front Panel and via communications, and T1-T8’s

kvarh Import/Export and kVAh are only available via communications.

4.8 Time Synchronization

The PMC-660 provides timestamps for all recorded data, so the clock needs to be configured properly

for event and power quality analysis.

The PMC-660 comes with a 6ppm, battery-backed real-time clock that has a maximum error of 0.5s per

day. If the supply power is lost or removed, the internal battery keeps the real-time clock running until

power is restored.

There are several methods to synchronize the PMC-660’s clock:

1) PMC Setup can be used to manually set the time of an individual meter through the “Set Time”

function on the Manual Operate page using the computer’s clock as the clock source.

2) PecStar® iEMS can be configured to provide regular time synchronization by broadcasting time-

sync packets over the connected medium, whether it be RS485 or Ethernet. The default time of

Table 5-1 Basic Measurements

Notes:

1) When the Wiring Mode is Delta or 3P3W, the per phase line-to-neutral Voltages, kWs, kvars, kVAs and P.F.s have no

meaning, and their registers are reserved.

2) For the DI Status register, the bit values of B0 to B5 represent the states of DI1 to DI6, respectively, with “1” meaning Active

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

3) For the DO Status register, the bit values of B0 to B2 represent the states of DO1 to DO3, respectively, with “1” meaning

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

4) The Alarm Status register, the bit values indicates the various Alarm states with “1” meaning Active and “0” meaning

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

5) The range of the SOE/PQ /WFR/IER/DR Log Pointer is between 0 and 0xFFFFFFFFH. The pointer is incremented 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 SOE Log/PQ Log/WFR Log/IER Log/DR Log is performed from the Front Panel or via
communications, its corresponding Log Pointer will be reset to zero. Use the following equation to determine the latest log
location:

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

Where Log Depth = 512 for SOE Log, 1000 for PQ Log, WFR Recording Depth for WFR Log, IER Recording Depth for IER

Log and DR Recording Depth for DR Log.

6) The Total Memory Size of the PMC-660 is 4MB (4096kB). Used Memory = 3936kB - Available Memory.

7) The Device Operating Time means the accumulated Operating Time (or Running Hours) whenever any per-phase Current

has exceeded the Current On Threshold (Register 6200). 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) I Residual register is meaningful only if the meter is equipped with the I4 option.

5.2 Energy Measurements

5.2.1 Total Energy Measurements

The Energy registers have a maximum value of 1,000,000,000 and will roll over to zero automatically

when it is reached. The PMC-660 also provides energy measurements in fractional values if they are

required. Using the “Fractional” registers, having units such as Wsec, varsec and VAsec, the user can

obtain decimal resolution for achieving higher accuracy. For example, if the value of the kWh fractional

register is 3200000 W sec, the decimal value is 3200000/3600000=0.8889kWh. If the higher resolution

is not required, it is not necessary to read the fractional energy registers.

5.8.1 Read General Reference Packet Structure (Function Code 0x14)

Modbus function code 0x14 is used to access to the Energy Log, PQ Log, Data Recorder Log and

Waveform Recorder Log. The table below list the file format.

Table 5-23 Read Reference/ Response Request Packet

1) Start Address = [Log #X Pointer / Log #X Depth].

2) In the Request Packet, the File Number parameter is used to reference which log to read:
a) For Energy Log, File Number = 17
b) For PQ Log, File Number = 18
c) For Data Recorder Logs 1 to 16, File Number = 1 to 16
d) For Waveform Recorder Log, File Number = 19 to 50

3) In the Response Packet, N represents the number of logs returned, and N

is the length of a single

0

log:

e) For Energy Log, N
f) For Data Recorder, N

= n*4+8 where n is the number of parameters for the Energy Log

0

= n*4+8 where n is the number of parameters for a particular Data

0

Recorder

g) For PQ Log, N
h) For Waveform Recorder Log, N

= 16

Notes:

1) Please refer to Section 5.8.1 Read General Reference Packet Structure for how to retrieve the DR log.

5.8.5 Waveform Recorder Log Data Structure

The WF data contains the secondary side value. The Voltage data returned is 10 times of the actual

secondary Voltage and the Current data is 1000 times of the actual secondary Current. Therefore, the

primary side Voltage and Current values are calculated using the following formulas:

Primary Voltage Value = Voltage Data × PT Ratio ÷ 10

Primary Current Value = Current Data × CT Ratio ÷ 1000

For 5A configuration, PT Ratio × CT Ratio must be less than 1,000,000

2) The last Octet of the IP Address, Subnet Mask and Gateway can neither be “0000 0000” nor “1111 1111”.

If the IP Address is “192.168.8.97”, write “0xC0A80861” to this register. The default values for the IP Address, Subnet Mask

and Gateway Address are 192.168.0.100, 255.255.255.0 and 192.168.0.1, respectively.

3) The Predicated Response setup parameter allows the user to adjust the sensitivity of the predicted demand output. A
value between 70 and 99 is recommended for a reasonably fast response. Specify a higher value for higher sensitivity.

4) 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 5-31 DIs and the Number of Tariffs Setup

5) Analog Output Parameters

If PF Total is chosen as the AO parameter, the values for ZERO (zero scale) and FULL (full scale) should be set as 1000 times
the actual value. The Units for voltage, current, kW, kvar, kVA and FREQ are V, A, kW, kvar, kVA and Hz, respectively.

Table 5-32 Analog Output Parameters

6) Recommended Pulse Constant settings for the different Line Voltage & Current Inputs

Table 5-33 Pulse Constant

7) 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 Self-
Read 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.

8) If the PMC-660 is not equipped with the Ethernet Port, SNTP is disabled.

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

5.9.6 Waveform Recorder (WFR) Setup

The PMC-660 provides 2 independent groups of WFR with a combined total of 32 entries. Each WFR can

simultaneously capture 3-phase Voltage and Current signals at a maximum resolution of 256 samples

per cycles.

Table 5-47 Waveform Recorder Setup Parameters

Notes:

1) The total capacity of WFR 1 and WFR 2 is 32, i.e. WFR Log 1 Recording Depth + WFR Log 2 Recording Depth <= 32.

2) The valid WFR formats (# of samples/cycle x # of cycles) include 16x320, 32x160, 64x80, 128x40 and 256x20.

3) When the WFR format is 256x20, the range of “Pre-fault Cycle” is between 0 and 5. Otherwise, the range is between 0 and

10.

4) WFR Log Size=(Number of Samples*Number of Cycle*2+10)*Recording Depth; The Log Size is rounded up to the nearest

kB.

5) Modifying the Setup Parameters of WFRx will clear the WFRx Log and reset WFRx Pointer will be reset to “0”.

Table 5-48 TOU Basic Setup

Notes:

1) If DI1 is not programmed as a Tariff Switch, the TOU will function based on the TOU Schedule. If at least one DI (DI1) is

programmed as a Tariff Switch, the TOU Schedule will no longer be used and the Tariff switching will be based on the status
of the DIs.

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.

Table 5-49 TOU Switch Time Format

5.9.7.2 Season

The PMC-660 has two sets of Season setup parameters, one for each TOU. The Base Addresses for the

two sets are 16100 and 17100, respectively, where the Register Address = Base Address + Offset. For

example, the register address for TOU #1’s Season #2’s Start Date is 17100+4 = 17104.

2) Setting a Period’s Start Time as 0xFFFF terminates the Daily Profile’s settings. All later Daily Profile’ setup parameters will

3) The minimum interval of a period is 15 minutes.

4) The Start Time of a particular Period must be later than the previous Period’s.

5.9.7.4 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-660 has two sets of Alternate Days setup parameters, one for each TOU. The Base Addresses

for the two sets are 16700 and 17700, respectively, where the Register Address = Base Address + Offset.

For example, the register address for TOU #2’s Alternative Day #2’s Date is 17700+3 = 17703.

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

5.9.8 DO 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-660 does

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

Only”. The DO Status register 0098 should be read instead to determine the current DO status.

The PMC-660 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 (6185) since Firmware

V2.00.00, 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”

5.10 Time

There are two sets of Time registers supported by the PMC-660 – Year / Month / Day / Hour / Minute /

Second (Registers # 60000 to 60002) and UNIX Time (Register # 60004). When sending time to the PMC-

660 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 Jan 1,

2000 00:00:00 will be rejected.
