Chapter 4 Applications

4.1 Inputs and Outputs

4.1.1 Digital Inputs (PMC-340B Only)

The PMC-340B comes standard with three self-excited Digital Inputs that are internally wetted at 24
VDC. Digital Inputs on the PMC-340B can be used in the following applications:

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) Tariff Switching Up to 2 Digital Inputs may be used to select to which of the 4 Tariffs the

energy consumption should be accumulated. The 2 Digital Inputs (DI1 and
DI2) represent 2 binary digits where Tariff 1=00, Tariff 2=01, Tariff 3= 10 and
Tariff 4=11 where the least significant digit represents DI1 and the most
significant digit represents DI2. 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 V1.00.01. Tariff switching as a result of DI changes will be stored
as an event in the SOE Log.

The following table describes the DI setup parameters that can be programmed over communications:

4.1.2 Energy Pulse Output

The PMC-340 comes standard with one front panel LED Pulse Output and one Solid State Relay Output
for energy pulsing. Energy Pulse Output is typically used for accuracy testing. Energy Pulsing can
be enabled from the front panel through the Energy Pulse setup parameter. The pulse constant can
be configured through the Pulse Constant setup parameter as 1/10/100 pulses per kXh for the 100A
Direct Input option and 1000/3200 pulses per kXh for the 5A CT Input option, respectively, where kXh
may be kWh or kvarh.

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 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 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.

Default=0xFFFF

4.3 Power Quality

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 Power Quality Parameters

The PMC-340 provides the following PQ parameters:

4.3.2.1 Harmonics

The PMC-340 provides THD, TOHD, TEHD and individual harmonics up to the 31st order. All harmonic
parameters are available through communication while THDs are available on the front panel display.
In addition, the PMC-340 also provides TDD, K-factor and Crest-factor measurements for Current,
which are only available through communication.

4.3.2.2 TDD

Total Demand Distortion (TDD) is defined as the ratio of the root mean square (RMS) of the harmonic

current to the root mean square value of the rated or maximum demand fundamental current,
expressed as a percentage.
TDD of the Current I is calculated by the formula below:

where

IL = maximum demand of fundamental current
h = harmonic order
I

h

= rms load current at the harmonic order h

4.3.2.3 K-Factor

CET Inc.

26

K-Factor is defined as the weighted sum of the harmonic load currents according to their effects on

transformer heating, as derived from ANSI/IEEE C57.110. A K-Factor of 1.0 indicates a linear load (no
harmonics). The higher the K-Factor, the greater the harmonic heating effects.

for the Max./Min. Self-Read operation. Please refer to Section 4.5 for a complete description of the
Self-Read Time and its operation.
The Max./Min. Log of This Month can be reset manually from the front panel or via communications.

4.4.2 Monthly Energy Log

The PMC-340 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.

4.4.4 SOE Log (PMC-340B Only)

The PMC-340B’s SOE Log can store up to 16 events such as Power-On, Power-Off, 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 ±1 ms resolution.

All events can be retrieved via communications for display. If there are more than 16 events, the
newest event will replace the oldest event on a first-in-first-out basis. The SOE Log can be reset from
via communications.

4.4.5 Data Recorder Log (PMC-340B Only)

The PMC-340B comes equipped with 2MB of memory and provides one Data Recorder capable of
recording a maximum of 16 parameters. 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 programming of the Data Recorder is only supported over communication. The Data Recorder
provides the following setup parameters:

The Data Recorder Log is only operational when the values of Trigger Mode, Recording 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

CET Inc.

29

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.

4.5 Time of Use (TOU)

Time-Of-Use (TOU) is used for electricity pricing that varies depending on the time of day, day of week,
and the season. The TOU system allows the user to configure an electricity price schedule inside the
PMC-340 and accumulate energy consumption into different TOU rates based on the time of
consumption. TOU programming is only supported through communications.

The TOU feature on PMC-340 supports two TOU schedules, which can be switched at a pre-defined
time. Each TOU schedule supporting:

 Up to 12 seasons
 90 Holidays or Alternate Days and 3 Weekdays
 20 Daily Profiles, each with 12 Periods in 15-minute interval
 4 Tariffs

Instead of using the TOU schedule to switch between Tariffs, the PMC-340 supports Tariff switching
based on the status of DI1 to DI2, which is supported in Firmware V1.00.01 or later.

The 2 Digital Inputs (DI1 and DI2) represent 2 binary digits where Tariff 1=00, Tariff 2=01, Tariff 3= 10,
and Tariff 4=11 where D1 represents the least significant digit and D2 represents the most significant
digit. As soon as DI1 and/or DI2 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 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 5-1 Basic Measurements

Notes:

1) The FP Counter and Comm. Counter will be incremented every time some important setup

parameters, which may affect the accuracy of Energy registers and DI Pulse Counters or the way
they are calculated, are changed via Front Panel or Communication, respectively. The FP
Counter is incremented every time a relevant setup parameter is changed via the Front Panel,
while the Comm. Counter is incremented every time a single packet is sent to change one or
more relevant setup parameters through communications. The following actions may trigger
these counters to increment:

 Changing Setup Parameters:

o Wiring Mode, PT and CT ratios and I Polarities
o DI setup parameters
o Energy Pulse Constant
o Preset Energy Value
o Demand Period and No. of Sliding Windows
o TOU setup registers
o Manual Time Set (via Front Panel only)

 Clear Actions via Front Panel:

o Clear All Energy
o Clear All Demand
o Clear All Max./Min.
o Clear All DI Counters

 Clear Actions via Communication:

o Clear Monthly Energy Log (Register 9600)
o Clear Energy (Register 9601)
o Clear Monthly Energy Log of Present Month (Register 9602)
o Clear Peak Demand Log of This Month (Register 9603)
o Clear All Demand Registers and Logs (Register 9604)
o Clear Device Operating Time (Register 9607)
o Clear All Data (Register 9608)
o Clear DI1 Counter (Register 9609) (only when DI1 = Energy Pulse Counter)
o Clear DI2 Counter (Register 9610) (only when DI2 = Energy Pulse Counter)
o Clear DI3 Counter (Register 9611) (only when DI3 = Energy Pulse Counter)

2) The PMC-340 has one SOE Log and one 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 DR does not contain any
Log. If a Clear Log is performed via communications, its 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 Pointer may be the SOE Log Pointer or DR Log Pointer
and Log Depth is as follows:

SOE Log Depth = 16 (fixed)
DR Log Depth = DR Recording Depth (see Section 5.11 Data Recorder Setup)

3) For the DI Status register, the bit values of B0 to B2 represent the states of DI1 to DI3,

respectively, with “1” meaning active (closed) and “0” meaning inactive (open).

4) The following table illustrates the Wiring Diagnostic Status with 0 meaning Normal and 1 meaning

5) The Device Operating Time means the accumulated Operating Time whenever any per-phase

Current exceeds 2% of I

nominal

(5A), which is 100mA. The Device Operating Time data is stored

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

5.2 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 actual energy value is 0.01 times of the register value.

Table 5-20 Monthly Energy Log

CET Inc.

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 PMC-340 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, ……”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 SOE Log (PMC-340B Only)

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-1/16)*8

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 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

4) The Monthly Energy Log Self-Read Time supports only 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 * 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.

Table 5-28 Data Recorder Setup

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. The value of the Recording Offset parameter
should be less than the Recording Interval parameter.

3) Please refer to Appendix A for a complete list of Data Recorder Parameters.

Table 5-29 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 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 schedules.

Table 5-34 Daily Profile Data Structure

Notes:

1) Daily Profile #1’s Period #1 Start Time is always 00:00 and cannot be modified.

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

Profile’ setup parameters will be ignored, and the previous Period’s duration is from its Start Time
to the end of the day.

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.

5.12.4 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-340 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 5-36 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-340 – Year / Month / Day / Hour / Minute
/ Second (Register # 60000 to 60002) and UNIX Time (Register # 60004). When sending time to the
PMC-340 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

CET Inc.

51

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.

Notes:

1) Writing 0xFF00 to the Clear Monthly Energy Log register to clear the Monthly Energy Log of the

last 1 to 12 months, excluding the Monthly Energy Log for the Present Month.

2) Writing 0xFF00 to the Clear Energy register to clear the 3-Ø Total and Per-Phase energy registers.

3) Writing 0xFF00 to the Clear Monthly Energy Log of Present Month register to clear the Monthly

Energy Log of the Present Month.

4) Writing 0xFF00 to the Clear Peak Demand Log of This Month register to clear Peak Demand Log

of This Month (Since Last Reset) when the Self-Read Time register is set for automatic Self-Read
operation. The Peak Demand of Last Month will not be cleared. If the Self-Read Time register
is set for manual operation with a register value of 0xFFFF, the Peak Demand of This Month (Since
Last Reset) will be transferred to the Peak Demand of Last Month (Before Last Reset) and then
cleared.

5) Writing 0xFF00 to the Clear All Demand Registers register to clear all Demand registers and logs,

including Real-time Present Demand, Peak Demand Log of This Month (Since Last Reset) and Last
Month (Before Last Reset).

6) Writing 0xFF00 to the Clear Max./Min. Log of This Month register to clear the Max./Min. log of

This Month (Since Last Reset) when the Self-Read Time register is set for automatic Self-Read
operation. The Max./Min. log of Last Month will not be cleared. If the Self-Read Time register
is set for manual operation with a register value of 0xFFFF, the Max./Min. log of This Month (Since

CET Inc.

52

Last Reset) will be transferred to the Max./Min. log of Last Month (Before Last Reset) and then
cleared.

7) Writing 0xFF00 to the Clear All Max./Min. Log register to clear both the Max./Min Log of This

Month (Since Last Reset) and the Max./Min. Log of Last Month (Before Last Reset).

8) Writing 0xFF00 to the Clear All Data register to perform the Clear operation for the action

specified in registers # 9600 to 9607 and # 9609 to 9613.
