An Ideal for Electric Automation SCADA Systems
The Acuvim II series meter is the ideal choice for replacing traditional, analog
electric meters. In additon to providing clear real-time readings on the meter
front, it can also be used as a remote terminal unit (RTU) for monitoring and
controlling for a SCADA system. Users can access all measurement parameters
via the standard RS485 communication port (or the optional Ethernet port) with
the ModbusTM protocol.
Energy Management
The Acuvim II series meter is able to measure bidirectional, four quadrants
kWh and kvarh. It provides maximum/minimum records for power usage and
power demand parameters. All power and energy parameters can be viewed
remotely via software in order to easily monitor various parameters. In addition,
measurement tables can be viewed from the free Acuview software.
Remote Power Control
This meter is designed for measuring and monitoring power quality parameters.

Power Quality Analysis
Utilizing digital signal processing (DSP) technology, the Acuvim II series meter
provides high accuracy power quality analysis and supports remote monitoring
via the Ethernet module. The meter continuously updates metering results and
allows users to access the meter online to monitor parameters such as voltage
and current THD, harmonics, voltage crest factor, current K factor, and voltage
and current unbalance factor etc.
Data Logging
The Acuvim IIR/IIE/IIW meter contains 8 megabytes ,IIW contains 8 megabytes
of onboard memory for data logging and historical trending. Since the meter
contains a real-time clock, all events and logged data will be time stamped.
Time of use (TOU-Acuvim IIE)
User can assign up to 4 different tariffs (sharp, peak, valley and normal) to
different time period within a day according to the billing requirements. The
meter will calculate and accumulate energy to different tariffs according to the
meter’s internal clock timing and TOU settings.
Power Quality Event Logging
When a power quality event happens, such as voltage sag and swell, etc, Acuvim
IIW will record the timestamp and the triggering condition of the event. It can
save up to 50, 000 power quality events.
Waveform Capture
Acuvim IIW can record 100 groups of voltage and current waveforms. It logs at
64 points per cycle. It provides the waveform record of 10 cycles before and after

Control Power
There are 2 options for the Control Power of the
Acuvim II series meter:
1. Standard: 100~415Vac (50/60Hz) or 100-300Vdc
2. Low Voltage DC Option: 20-60Vdc
The 2 options must be chosen according to the
application. Please see the ordering information
appendix for further details.
The meter's typical power consumption is very low
and can be supplied by an independent source
or by the measured load line. A regulator or an
uninterrupted power supply (UPS) should be used
under high power fluctuation conditions. Terminals
for the control power supply are 11, 12 and 13 (L,
N, and Ground). A switch or circuit-breaker shall be
included in a building installation. It shall be in close
17
proximity to the equipment, within easy reach of the operator, and shall be
marked as the disconnecting device for the equipment.
Fig 2-7 Power supply
A fuse (typical 1A/250Vac) should be used in the auxillary power supply loop.
No. 13 terminal must be connected to the ground terminal of the switchgear.
An isolated transformer or EMC filter should be used in the control power supply
loop if there is a power quality problem in the power supply.
NOTE
A filter should be
used if there is
an EMI problem.
Fig 2-8 Power supply With EMC filter
Choice of wire of power supply is AWG22-16 or 0.6-1.5mm2.
Voltage Input
Maximum input voltage for the Acuvim II series meter shall not exceed
400LN/690LL VAC rms for three phase or 400LN VAC rms for single phase.
Potential Transformer (PT) must be used for high voltage systems. Typical
secondary output for PTs shall be 100V or 120V. Please make sure to select an
18
appropriate PT to maintain the measurement accuracy of the meter. When
connecting using the star configuration wiring method, the PT's primary side
rated voltage should be equal to or close to the phase voltage of the system to
utilize the full range of the PT. When connecting using the delta configuration
wiring method, the PT's primary side rated voltage should be equal to or close
to the line voltage of the system. A fuse (typical 1A/250Vac) should be used in
the voltage input loop. The wire for voltage input is AWG16-12 or 1.3-2.0mm2.
Note: In no circumstance should the secondary of the PT be shorted. The
secondary of the PT should be grounded at one end. Please refer to the wiring
diagram section for further details.
Current Input
Current Transformers (CTs) are required in most engineering applications.
Typical current rating for the secondary side of the CT shall be 5A (standard)
or 1A (Optional), please refer to the ordering information appendix for further
details. CTs must be used if the system rated current is over 5A. The accuracy
of the CT should be better than 0.5% with rating over 3VA is recommended in
order to preserve the meter's accuracy. The wire between CTs and the meter
shall be as short as possible. The length of the wire have an effect on the
accuracy.
The wire size of current input is AWG15-10 or 1.5-2.5mm2.
Note: The secondary side of the CT should not be open circuit in any
circumstance when the power is on. There should not be any fuse or switch in
the CT loop. One end of the CT loop should be connected to the ground.
Vn Connection
Vn is the reference point of the Acuvim II series meter voltage input. Low wire
resistance helps improve the measurement accuracy. Different system wiring
19
modes require different Vn connection methods. Please refer to the wiring
diagram section for more details.
Three Phase Wiring Diagram
This meter can satisfy almost any kind of three phase wiring diagrams. Please
read this section carefully before choosing the suitable wiring method for your
power system.
Voltage and current input wiring mode can be set separately in the meter
parameter setting process. The voltage wiring mode can be set as 3-phase
4-line Wye (3LN), 3-phase 3-line direct connection(3LL), 3-phase 3-line open
delta(2LL), single phase 2-line(1LN) and single phase 3-line(1LL) . The current
input wiring mode can be set as 3CT, 2CT and 1CT. The voltage mode can be
grouped with the current mode as 3LN-3CT (3CT or 2CT, 3LL-3CT, 2LL-3CT, 2LL2CT, 1LL-2CT, 1LN-1CT).
2.3.3 Voltage Input Wiring
3-Phase 4-Line Wye Mode (3LN)
The 3-Phase 4-Line wye mode is commonly used in low voltage electric
distribution power systems. For voltage lower than 400LN/690LL Vac, power
line can be connected directly to the meter's voltage input terminal as shown in
fig 2.9a. For high voltage systems (over 400LN/690LL Vac), PTs are required as
shown in fig 2.9b. The meter should be set to 3LN for both voltage levels.
20
Fig 2-9a 3LN direct connection
Fig 2-9b 3LN with 3PT
3-Phase 3-Line Direct Connection Mode (3LL)
In a 3-Phase 3-Line system, power line A, B and C are connected to V1, V2 and
V3 directly. Vn is floated. The voltage input mode of the meter should be set to
3LL.
21
Fig 2-10 3LL 3-Phase 3-Line direct connection
3-Phase 3-Line open Delta Mode (2LL)
Open delta wiring mode is often used in high voltage systems. V2 and Vn are
connected together in this mode. The voltage input mode of the meter should
be set to 2LL for this voltage input wiring mode.
Fig 2-11 2LL with 2PTs
2.3.4 Current Input Wiring
3CT
The 3CT current wiring configuration can be used when either 3CTs are
connected (as shown in Fig 2.13) or 2CTs are connected (as shown in Fig 2.14)
22
to the system. In either case, there is current flowing through all three current
terminals.
Fig 2-12 3CTs a
Fig 2-13 3CTs b
2CT
The difference between Fig 2.14 and Fig 2.15 is that no current flows through
current input terminal I21 and I22. The meter should be set to the I2 value
which is calculated from formula i1+i2+i3=0. The current input mode of the
meter should be set to 2CT .

1200m (4000ft). The Acuvim II series meter is used as a slave device of masters
such as a PC, PLC, Data Collector or RTU.
If the master does not have RS485 communication port, a converter (such as a
RS232/RS485 or a USB/RS485 converter) will be required. Typical RS485 network
topologies include line, circle and star (wye).The shield of each segment of the
RS485 cable must be connected to the ground at one end only.
Every A(+) should be connected to A(+), B(-) to B(-), or it will influence the
network, or even damage the communication interface.
The connection topology should avoid “T” type which means there is a new
branch and it does not begin from the beginning point.
Keep communication cables away from sources of electrical noise whenever
possible.
When using a long communication cable to connect several devices, an anti
signal reflecting resistor (typical value 120Ω-300Ω/0.25W) is normally added
to the end of the cable beside the last meter if the communication quality is
distorted.
Use RS232/RS485 or USB/RS485 converter with optical isolated output and
surge protection.

54
DI of AXM-IO2 can be used as the pulse counter, each DI function corresponds
to one bit of a 4-bit register. The correspondence bit of 0 means that the DI
works as the digital status input and the correspondence bit of 1 means that the
DI works as the pulse counter. For example, if the setting value is 0001, it means
that DI1 is set as the pulse counter and other DIs work as digital status inputs.
If the DI works as a pulse counter, when the number of pulses counted by the
DI equals to the pulse constant, the pulse counter will increase by one. This
means that the actual pulse number equals the number of pulses counted
multiplied by the pulse constant.
DO of AXM-IO1 can be used as either alarm output or energy pulse output.
ALM: alarm output; PUL: energy pulse output
Range from 20-1000 ms.
Choose output energy type for DO1. Range from 0-4. 0: no output; 1: import
active energy; 2: export active power; 3: import reactive energy; 4: export
reactive energy.
Follow the DO1 setup method to setup DO2.
If DO type is set as alarm output, DO1 and DO2 output type parameters will
have no effect.
Range from 0 to 3, 0: 0-20mA; 1: 4~20mA; 2: 0-5V; 3: 1-5V.
Be aware that modules with current option cannot be set as voltage type (i.e.
option 2 and 3 are unavailable); modules with voltage option cannot be set as
current type (i.e. option 0 and 1 are unavailable).
For AO1 and AO2 transforming parameter:
Range: 0~29, see Chapter 5 page 99 "AO transforming parameter settings" for
more details.
55
DI of AXM-IO3 can be used as the pulse counter, each DI function
corresponds to one bit of a 4-bit register. The correspondence bit
of 0 means that the DI works as the digital status input and the
correspondence bit of 1 means that the DI works as the pulse counter. For
example, if the setting value is 0001, it means that DI1 is set as the pulse
counter and other DIs work as digital status inputs.
If the DI works as a pulse counter, when the number of pulses counted
by the DI equals to the pulse constant, the pulse counter will increase
by one. This means that the actual pulse number equals the number of
pulses counted multiplied by the pulse constant.
When set as control output, relays have two control methods: latch or
pulse
Relays of AXM-IO3 can be used as alarm output or control output.
ALM:alarm output; CTRL:control output
If relay pulse control method is selected, the relay contact will close for
a preset period and open afterwards. The pulse width range is 50~3000
ms.
Range from 0 to 3. 0: 0~20mA; 1: 4~20mA; 2: 0~5V; 3: 1~5V.
Be aware that modules with current option cannot be set as voltage type
(i.e. option 2 and 3 are unavailable); modules with voltage option cannot
be set as current type (i.e. option 0 and 1 are unavailable).
Note: The figure shows the rolling sequence for using key P. If using E key for
rolling page, the sequence will reverse.

are disabled; 00001 means only the first channel is enabled; 65535 means that
all channels are enabled. Refer to section 4.4 on page 65 for more details.
"AND" logic relationship can be set among channels. When an "AND" logic is in
place, both channels have to be triggered before the meter sends out the alarm
signal. The logic can be set according to the predefined rule (refer to section 4.4
for more details). User can setup up to 8 logic relationships for alarming. Each
logic relationship is controlled and enabled 1 bit each from a 16-bit register (only
the lower 8 bits are used). Bit value of 1 means that the corresponding logic
relationship is enabled whereas 0 means that the relationship is disabled. The
meter will display this 8-bit value in decimal numbers (for different relationship
combination). For example, 000 means that all relationships are disabled; 001
means only the first relationship is enabled; 255 means that all relationships are
enabled.
When DO1 works in alarming mode, a 16-bit register is used to control which
channels are associated with this output. Similar to the alarm channel selection,
this 16-bit value is expressed in decimal when reading on the meter front. For
example, 00000 means that no alarm channels are associated to this output;
00001 means that alarm channel 1 is associated to DO1; 65535 means that all
alarm channels are associated to DO1. Refer to section 4.4 for more details.
If 2 AXM-IO2 modules are attached to the meter, DO1 and DO2 denote to the
first and the second DO channel of AXM-IO21; DO3 and DO4 denote to the first
and the second DO channel of AXMIO22 respectively. DO2, DO3 and DO4 use
the same setup method as DO1.
61
Note: The figure shows the rolling sequence for using key P. If using E for rolling
page, the sequence will reverse.
3.8 Page Recovery Function
Acuvim II series meter has a page recovery function. This means that the meter
stores current display page in the non-volatile memory upon power loss and
reloads the page when power recovers. If power goes off when viewing under
the parameter setting mode, the meter will show voltage display when power
recovers. If power goes off when viewing under the expanded I/O module data
mode, and if this expanded I/O module is not connected when power recovers,
the meter will show the voltage display page instead.

4.8 Seal function
The Acuvim II series meter contains advanced metering tools and is able to
measure a multitude of power, energy and power quality parameters. Some
advanced functions may not be accessible directly from the meter front;
therefore, every meter comes with a powerful software that helps access the
information. This chapter introduces these functions and the software.
4.1 Basic Analog Measurements
Acuvim II series meter can measure voltage, current, power, frequency, power
factor, demand, etc. With high accuracy, as shown via the software below:
Fig 4-1 Real-Time Metering
64
Demand:
This meter consists of several types of demand calculation: total active power
demand, total reactive power demand, total apparent power demand, phase A
current demand, phase B current demand, and phase C current demand. When
demand is reset, demand memory registers are set as 0.
Demand calculating mode can be set as sliding window and thermal according
to user. The figure 4-7 shows how it works.
When using the sliding window interval method, user selects an interval from
1 to 30 minutes, which is the period of the calculation. The demand updates
every 1 minute as the window slides once.
Thermal demand method calculates the demand based on a thermal response
which mimics a thermal demand meter. User selects the period for the
calculation and the demand updates at the end of each period.
Energy:
This meter measures and accumulates energy in different directions (import and
export). For real-time energy monitoring, it accumulates energy for kWh, kvarh
and kVAh continuous (since its last reset).
Calculating mode
1. User can select different energy calculating modes, fundamental based or
full-wave based either from the meter front or via communication. Fundamental
based calculating is used to accumulate energy without taking harmonics into
consideration while full-wave based calculating is used to accumulate energy
including fundamental and harmonics.
Note: When fundamental based calculating mode is selected, PF calculation will
be based on the fundamental wave.
65
2. There are two ways to calculate reactive energy(power)
Mode 0: real reactive energy Mode 1: general reactive energy 3. User can choose primary energy or secondary energy either by pressing keys
from the meter front or via communication as shown in figure 4-7.
Note: Acuvim II is able to display either primary energy or secondary energy
on the LCD screen; however, it is only able to send out pulses according to
secondary energy via the AXM-IO module.
Fig 4-2 Energy and Power Quality Parameters
66
Current direction adjustment
Under normal circumstances, current flows from input terminal 1 to terminal
2 (i.e. from I11 to I12 for phase A current); however, current may flow in the
opposite direction due to incorrect wiring setup. Instead of rewiring the system,
the meter provides users an option to reverse the polarity of the current. By
default, current direction is set as "positive", to reverse the current polarity by
180 degrees, user can set current direction as "negative". Refer to Fig 4.7 for
more details.
Fig 4-3 Max/Min
67
4.2 Max/Min
Acuvim II series meter logs maximum and minimum value statistics for phase/
line voltages, current, power, reactive power, apparent power, power factor,
frequency, demand, unbalance factor, THD as well as the time they occur. All
data is stored in non-volatile memory so that statistic information can be
preserved even when meter is shut off. All maximum and minimum data can be
accessed via communication or from the meter front but time stamps can only
be accessed via communication. Statistics can be cleared via communication or
from the meter front.
4.3 Harmonics and Power Quality Analysis
1. Harmonics
Acuvim II series meter can measure and analyze THD, harmonics harmonics
2nd to 63rd, even HD, odd HD, crest factor, THFF, K factor etc. They are shown in
figure 4-2.
2. Phase angle:
Phase angle indicates the angle between phase A voltage and other voltage/
current parameters. Angle ranges from 0 to 360 degrees. This function is to
help users find out the relationship between all input signals avoiding wrong
wiring. When it is set to “2LL” or “3LL”, it gives out the phase angles of u23, u31,
i1, i2,i3 corresponding to u12. When it is set to “3LN”, it gives out the phase
angles of u2, u3, i1, i2 and i3 corresponding to u1. When it is set to “1LL”, it gives
out the phase angles of u2, i1, i2 corresponding to u1. They are shown in figure
4-4.
3. Sequence component and unbalance analysis
Acuvim II series meter is able to perform sequential analysis for the input signal.
68
It looks at the positive sequence, negative sequence and zero sequence of
the fundamental frequency and performs unbalance analysis for voltage and
current. Sequence components are shown in figure 4-4, unbalance of voltage
and current are shown in figure 4-1.
Fig 4-4 Sequence component and Phase angle(for example, 3LN)
4.4 Over/Under Limit Alarming
Acuvim II series meter has over/under limit alarming capabilites. When the
monitored parameter goes over/under the preset limit and stays at the level
over the preset amount of time delay, the over/under limit alarm will be
triggered. The over/under limit value and its time stamp will be recorded in the
69
alarming log. The meter can record up to 16 alarming records. When extended
I/O modules are attached, digital outputs (DO) and relay outputs (RO) can be
triggered upon alarm conditions and used to activate downstream devices such
as a beacon light or a buzzer.
Before using the alarming function, alarm conditions such as logic dependency,
target setpoint, time delay etc must be set correctly. Settings can be accessed
and modified from the software via communication connection as shown in Fig
4-5.

Parameter code: select target parameter for alarm monitoring For example:
0-frequency, 44-AI4 sampling data.
Comparison mode: set alarming condition 1: greater than, 2: equal to, 3: smaller
than. For example: if you choose target parameter to be "frequency", condition
to be "greater than" and setpoint to be "50", alarm will be triggered when the
frequency is greater than 50Hz.
Note: setpoint value is the same as the actual value of the selected parameter.
Delay time: If the alarms condition lasts for the preset time period, the alarm
signal will be triggered. The delay range is from 0 to 3000 (unit: 10ms). When it
is set to 0, there is no delay, alarm will be triggered when the alarm condition is
met. If it is set to 20, there will be a 200ms (20 x 10ms) delay.
Output to relay: 0-alarming signal will not be sent to RO; if it is set as 1 and AXMIO11 is connected, it will output to RO1 when alarm triggers. RO1 will be turned
off when all alarms output to RO1 are cleared. RO2~RO8 work in the same
manner as RO1.
71
Note: 1) If RO is under alarming mode, it can only work in “latch” mode.
2) If the number is 51~79, there are special guide for contrast method and
meaning of parameters, please refer to Chapter 6.
After setting up the alarming parameters, user must also setup the global
settings in order for the alarm to work properly.
2. Global settings
Register addresses for global alarm settings are from 1046H~104dH. Please
refer to section 5.3, page 95 "Global alarming settings" for more details.
“Global alarming enable” determines whether the alarming function of the
meter is activated or not. The alarming function is enabled when it is set as "1".
When “Alarming flash enable“ is set as “1”, backlight will flash when alarm is
triggered.
“Alarming channel enable setting” determines whether the corresponding
alarm group is enabled or not. There are 16 groups in all and each one is
corresponding to one bit of a 16-bit register. The corresponding bit must be set
to "1" in order to activate the alarm channel.
Logic "AND" between alarm setting: The 16 alarming records in the meter are
divided into 8 pairs. Each pair has two alarm groups. The two groups can be
logically “AND” by controlling the logic check box. When two groups are “AND”,
alarming triggers only if both AND conditions are met. If the "AND" logic box is
unchecked, the two alarm channels will work independently.
The 8 "AND" logic pairs are arranged as follows: 1st, 2nd channel form Pair 1; 3rd,
4th channel form Pair 2; 5th, 6th channel form Pair 3; 7th, 8th channel form Pair 4;
9rd, 10th channel form Pair 5; 11th, 12th channel form Pair 6; 13th, 14th channel form
Pair 7; 15th, 16th channel form Pair 8.
72
This function is controlled by the lower 8 bits of the 16-bit register and each
bit is corresponding to a pair. “1” means this function is enabled and “0” means
disabled.
“Alarming output to DO1 setting”: When “Digital output mode” is set to “1”,
DO1 can be used as alarming output. A 16-bit register is used to perform this
function, its bit0~bit15 correspond to the 1st ~16th group respectively. When
the related I/O module is connected and is under alarming mode, and if the
corresponding bit is set to 1 and the alarming condition is met, alarm signal will
be sent to DO1. DO1 will be turned off when all alarms correspond to DO1 are
cleared. If related bit is set to 0, that alarm channel will not issue alarm signal to
DO1. DO2~DO4 work in the same manner DO1.
After completing the setup steps correctly, alarming function can be used.
3. Setting Example
Here is an example showing how to apply the logic "AND" function for a pair of
alarm channels.
The conditions are as follows: I1 greater than 180A, delay 5s for the 1st alarm
channel; U1 less than 9980V, delay 10s for the 2 nd alarm channel. No alarm
signals will be sent to outputs. The CT primary value of I1 is 200A, and CT2 is
5A. The PT ratio for U1 is 10000:100. The following shows how all the related
registers are to be set.
Settings of first group:
“Parameter code (104eH)” is set to 9, which stands for I1.
“Comparison mode (104fH)” is set to 1, which stands for "greater than".
“Setpoint value (1050H)” is set to 4500, according to the relationship between
actual value and communication value (I=Rx * (CT1/CT2) /1000).
73
“Delay time (1051H)” is set to 500, so the actual delay time is 500*10ms=5s.
“Output to relay (1052H)” is set to 0, because there is no output to RO.
Settings of second group:
“Parameter code (1053H)” is set to 1, which stands for U1.
“Comparison mode (1054H)” is set to 3, which stands for "smaller than".
“Setpoint value (1055H)” is set to 998, according to the relationship between
actual value and communication value (U=Rx X (PT1/PT2) /10).
“Delay time (1056H)” is set to 1000, so the actual delay time is 1000*10ms=10s.
“Output to relay (1057H)” is set to 0, because there is no output to RO.
Global settings:
“Alarming channel enable setting (1048H)” set to 0003H to enable the first and
the second channel.
“Logic "AND" between alarming setting (1049H)” set to 0001H to enable logic
"AND" in Pair 1.
“Alarming output to DO1 setting (104aH)” set to 0, since no output to DO1.
“Alarming output to DO2 setting (104bH)” set to 0.
“Alarming output to DO3 setting (104cH)” set to 0.
“Alarming output to DO4 setting (104dH)” set to 0.
“Alarming flash enable (1047H)” set to 0 to disable backlight flashing when
alarming occurs.
“Global alarming enable (1046H)” set to 1 to enable over/under limit alarming.
74
4. Records of Alarming Event
Acuvim II series meter has built in alarm logging capabilities. 16 entries can
be recorded in total. The record sequence of these entries do not depend
on the sequence of the 16 alarm channels. The meter begins logging alarm
status starting from the 1st record location to the last one. Alarm logs are being
recorded in a "cycle" fashion which means the latest event will overwrite the
oldest record. When over/under limit parameters return to normal, its value and
time stamp will be recorded as well. Therefore, users can determine the over/
under limit duration by checking the time difference.
Here is the 1st group of records. Other groups of records have the same format.

“Alarming status” indicates information of current alarm status. It is a 16-bit
unsigned integer. Parameter code is stored in the higher 8 bits. Bit1 indicates
whether logic "AND" is enabled or not, 1 means enabled and 0 means not. Bit0
indicates whether alarming has occured or recovered, 1 means occurred and 0
means recovered.Undefined bits are 0.
“Parameter code” specifies the monitored parameter.
“Value” shows the recorded value of the selected parameter when an alarm is
triggered and when it recovers.
75
“Time” indicates the time stamp with the accuracy in milliseconds (ms).
Alarming event will set bit0 of “system status (102EH)” to be 1. When software
send clear alarm command, Bit0 of “system status (102EH)” will be set to 0.
Alarming group number (1032H): the range is 0~16, 0 is no alarm record, and
others stand for which record is newest alarm. Alarming group number can be
saved during meter power off, and it is cycling recording.
Here is an example:

4.5 Data Logging
The Acuvim IIR/IIE/IIW meter provides data logging that records the data at a set
interval.This meter has 8 MegaBytes of memory which gives it extensive datalogging capabilities. It has a real-time clock that allows logs to be time-stamped
77
when log events are created.
1. Data log settings
The Acuvim IIR/IIE/IIW meter has three sets of historical data logs. Each log can be
independently programmed with individual settings, meaning that each can be
used to monitor different parameters. You can program up to 117 parameters
per log. You also have the ability to allocate available system resources among
the three logs, to increase or decrease the size of the individual historical logs.
The total size is no more than 100 sectors that has 64k bytes. The data log 1
setting is shown in Fig 4-8.
Fig 4-8 The data log 1 setting
78
Having three sets of historical logs provides you with the option of
programming each log with unique parameters. For example, you can program
Historical Log 1 to record measured values parameters (for example, Frequency,
Voltage, Current), Log 2 to record energy values parameters, and Log 3 to record
power quality parameters. Historical Log parameters can be selected from the
following thirteen groups:
• Real-Time Metering (Frequency; Instantaneous Voltage; Instantaneous Current;
Total and Per Phase Power and Power Factor; Neutral Current ; unbalance V/I;
load type; Current demand; and Per Phase/ Total Power demand)
• Energy (Ep_imp; Ep_exp; Ep_total; Ep_net; Eq_imp; Eq_exp; Eq_total; Eq_net
and Es)
• THD Volts AN/AB(THD, 2nd -63rd Harmonic Magnitudes, ODD, EVEN, CF and THFF
of Volts AN/AB)
• THD Volts BN/BC (THD,2nd -63rd Harmonic Magnitudes,ODD,EVEN,CF and THFF of
Volts BN/BC)
• THD Volts CN/CA (THD, average THD, 2nd-63rd Harmonic Magnitudes, ODD, EVEN,
CF and THFF of Volts CN/CA)
• THD IA (THD, 2nd -63rd Harmonic Magnitudes, ODD, EVEN, KF of IA)
• THD IB (THD, 2nd -63rd Harmonic Magnitudes, ODD, EVEN, KF of IB)
• THD IC (THD, average THD, 2nd -63rd Harmonic Magnitudes, ODD, EVEN, KF of IC)
• Sequence Component (positive, negative and zero sequence)
• Phase Angles(the angle between U1 and other voltage and current parameters.)
• DI Counter (the DI numbers of the IO modules)
79
• AO/AI Raw Value (the AO output register values and the AI sample register
values)
• AO/AI Value(the AO output values and the AI sample values)
The following procedures show how to select and store parameters in historical
log 1. The Group field determines the items that are available for selection.
1) Select a Group. The possible selections are: Real-Time Metering, Energy,
THD Volts AN/AB, THD Volts BN/BC , THD Volts CN/CA , THD IA , THD IB , THD IC,
Sequence Component, Phase Angles, DI Counter, AO/AI Raw Value and AO/AI
Value.
2) Select items for your log:
a. Highlight the parameter(s) you want to log into the meter's memory.
b. Click Add to add the parameter to the Selected Parameter Area.
c. To remove parameter(s), highlight them in the Selected Parameter Area and
click Remove.
3) Set the logging interval (in minutes). Interval can be set from 0 - 1444
minutes according to different application.
The logging interval determines when the meter takes a snapshot.When
interval is set as 0, the set of historical data log is disabled.
4) There are 100 sectors in total for the 3 historical data logs. User can assign
different sector size to each log according to different applications (as long as
the total sector sizes of the 3 logs do not exceed 100).
5) Three Modes of historical log:
A. Mode1: if correctly set historical log, can record without setting date and
time, depending on first-in first-out recycling log.
80
B. Mode2: if correctly set historical log, as set date and time, can record within
begin to end time. Record will stop after buffer is full.
C. Mode3: if correctly set historical log, as set hour and minute, only can record
while the running time is equal to setting hour and minute, depending on firstin first-out recycling log.
NOTES:
• If the memory of the historical data log is full, the meter will erase the first
sector in which the memory size is 65536 bytes (64kb). The following sector
(the second sector) will become the first sector and the data from the erased
sector will not be recoverable. Therefore, user should save the whole log before
memory is full to maintain all the data.
• There are two display fields at the bottom of the data log setting screen. They
show the registers in the logs ,the total bytes used and the bytes remaining
for this historical log. These fields are updated as you make selections on the
screen. The total number of bytes available per log record is approximately 234.
2. Retrieving logs
There are two ways of retrieving the logs: "read one window" and "read all".The
retrieval screen is shown in Fig 4-9.
81
Fig 4-9 Retrieval screen
The "read one window" method allows you to access and read a specific
log location at an offset from the first log. The "window record num" is the
maximum number of record entries the software can read at a time, it is
calculated by 246 / Record Size. The larger this number is, the faster data can
be retrieved. Log type is the logs you want to retrieve, for example, log type 0 is
data logging 1,log type 1 is data logging 2 and log type 2 is data logging 3.
The "read all" method accesses and reads the historical data log automatically,
the offset increases automatically until all the logs are retrieved.
The data logs contents are shown at the bottom of the page.
82
4.6 Time of use (TOU)
User can assign up to 4 different tariffs (sharp, peak, valleyand normal) to
different time period within a day according to the billing requirements. The
meter will calculate and accumulate energy to different tariffs according to the
meter’s internal clock timing and TOU settings.
TOU setting: User can set a maximum of 12 TOU seasons, each season can be
assigned to a TOU schedule (a maximum of 14 TOU schedules are available).
Each schedule can be divided up into 14 segments (in which each segment can
have its own tariff ).User can customize the TOU calendar (including its tariffs,
seasons, schedules and segments) according to different applications. To make
sure that the TOU calendar is setup correctly, the meter will check the TOU
settings according to the predefined rules (see below for “TOU setting format
requirement” for details).TOU function will be disabled if the TOU calendar is
set up incorrectly. If no errors are found in the calendar and the TOU function is
enabled, TOU energyaccumulation will begin.
TOU setting format requirement:
1. Season setting parameter: The calendar year will be divided up into different
seasons depending on the season setting parameter. The parameter can be
selected from any integer between 1 to 12. User must enter the correct value
for the season setting parameter in accordance to the TOU season table. If the
season setting parameter is set as 2, the first 2 slots of the TOU season table
must be set, otherwise it will be considered as an invalid input (TOU function
will be disabled).
2. TOU season format: Enter the start date into the TOU season table slot
following this format “MM-DD ID” - MM stands for the month, DD stands for the
day and ID stands for the TOU schedule ID (available from 01 to 14). The dates
should be organized so that they are in sequence according to the calendar
83
year (the earlier date comes first and the later date comes last). For example, if 3
seasons are selected, the date parameters are January 1, June 6 and September 7,
and TOU schedule 02, 01, 03 will be used respectively, the first TOU season table
slot shall enter 01-01 02, the second slot shall enter 06-06 01, and the third slot
shall enter 09-07 03. Entering 01-01 02 for the first slot, 09-07 03 for the second
slot and 06-06 01 for the third slot is considered invalid.
3. Schedule setting parameter: The number of available TOU schedules
depends on the schedule setting parameter. The parameter can be selected
from any integer between 1 to 14. This parameter determines the number of
TOU schedules available for the TOU calendar setting. A maximum of 14 TOU
schedules (from TOU Schedule #1 to TOU Schedule #14) can be used.
4. Segment setting parameter: Each TOU schedule consists of various timing
segments. The number of segments depends on the segment setting
parameter setup. The parameter can be selected from any integer between 1
to 14 (inclusively). User must enter the correct value for the segment setting
parameter in accordance to the TOU schedule table. If the segment setting
parameter is set as 3, the first 3 slots of the TOU schedule table must be set,
otherwise, it will be considered as an invalid input (TOU function will be
disabled).
5. TOU schedule format: Each TOU schedule represents a 24 hour cycle. Similar
to TOU season format, enter the start time into the TOU schedule table slot
following this format “HH:MM ID” - HH stands for hour (in 24 hr format), MM
stands for minutes and ID stands for tariffs (available from 00 to 03). The
time should be organized according to the hour sequence. For example, if 3
segments are selected, timing parameters are 01:00, 15:30, 22:45, the order of
the 3 segments should be one of the following: 01:00, 15:30, 22:45 or 15:30,
22:45, 01:00 or 22:45, 01:00, 15:30 Entering time information in a wrong
sequence (for example, entering 15:30, 01:00, 22:45) is considered as an invalid
operation, TOU function will be disabled.
84
6. Tariff setting parameter: This parameter corresponds to the number of tariffs
available for the TOU calendar and can be selected from any integer from 0 to 3.
The four tariffs: sharp, peak, valley and normal are represented by 4 integers: 0,
1, 2 and 3 respectively. If the tariff setting parameter is set to 3, all of the 4 tariffs
will be available for the TOU calendar; if the parameter is set to 1, only the first 2
tariffs (sharp and peak) will be available.
7. Holiday setting parameter: This parameter can be set from any integer
between 1 and 30, meaning a maximum of 30 holidays can be programmed to
the TOU calendar. If the holiday setting parameter is set as 3, the first 3 slots of
the holiday schedule must be set, otherwise it will be considered as an invalid
input (TOU function will be disabled).
Note: User can either customize the TOU calendar factory settings or use the
default factory settings. User can reset the TOU calendar to its default value
either via communication or from the meter front.
8. Holiday schedule: The holiday schedule uses the same format as the TOU
seasons “MM-DD ID”. User can select which TOU schedule to be used for the
holiday. The dates of the holiday schedule do not need to be organized in
a sequential order (i.e. the first slot can be January 1, the second slot can be
December 26 and the third slot can be December 25).
9. Daylight saving time (DST): Daylight saving time can be enabled in one of two
formats: The fixed date option, or a fixed day of one of the weeks in the month
(also named as the non-fixed date option). if you choose a fixed date option,
you set the format according to a fixed date, for the daylight saving time switch:
the format month / day / hour / minute / adjust time (in minutes). If you choose
non-fixed date option, DST will be implemented by which day of which week,
whose setting format is month/which day (i. e. Tuesday)/which week (i. e. 1st
week)/hour/minute/adjust time(in minutes).
85
By using the function, you can cause the instrument to automatically switch
to and from daylight saving time. When the clock starts to run to daylight
saving time, the meter will automatically adjust the clock to a time period in
advance, while the clock is running to the end of daylight saving time, meter
will automatically adjust the clock pushed back to a time period, as shown in
Fig 4-10

Users can preset holidays of the next decade via the meter software. The holiday
format is month/day/year; holiday code; holiday schedule. After the format
setup, click on "Make Holiday Settings (10 year)", then a holiday table for the
next decade will be generated.
Holiday Auto Switch: When Ten-year Holiday is enabled, if the current year of
86
the meter falls into the Ten-year Holiday setting, it automatically loads the Tenyear Holiday settings into the current TOU settings. If the current year of the
meter does not fall into the Ten-year Holiday setting, it remains the current TOU
settings.
Fig 4-11 ten years holiday table
11. Weekend Schedule: Weekend Setting (bit0 : Sunday; bit1 ~ bit6: Monday to
Saturday; bit 0 means not effective, bit 1 means effective). For example, when
the Weekend Setting bit0 is 1, it means Sunday is effective. When the Weekend
Setting bit1 is 1, it means Monday is effective. For example, if a user wants to set
Saturday and Sunday effective, he should put 65 (1000001) into the Weekend
Setting field. When the meter clock is within the preset Weekend Schedule, the
87
energy will accumulate under the tariff that corresponds to the Schedule.
Note: Holiday schedule has the highest priority among all the schedules.
Weekend schedule's priority is followed by Holiday schedule. When Holiday
schedule is not enabled, Weekend schedule has the highest priority, overiding
the normal (weekday) schedule.
Acuvim IIE can record maximum power and current demand under different
tariffs, as well as the time stamp of the maximum value. It can also clear the
maximum demand under diferent tarifs.
Except normal energy parameter readings, Acuvim IIE has 2 separate logs:
Current Month TOU and Prior Month TOU. When setup appropriately and when
TOU is enabled, energy will be accumulated in a month-to-month basis. The
current energy usage will be stored under Current Month TOU and is divided up
into different tariffs. When next month (or counting period) starts, all Current
Month TOU values will be moved to Prior Month TOU.
There are two ways of automatic resetting of current month TOU.
1.End of Month: This is the default method. All values from Current Month TOU
will be copied over to Prior Month TOU at the very beginning of each month (the
frst day of eachmonth at time 00: 00: 00). Current Month TOU will be cleared and
reset to 0.
2.Assigned Clock: User can select when the values from Current Month TOU
would be copied over to Prior Month TOU. User can set the time in the following
format “DD HH: MM: SS” - DD stands for day, HH stands for hour, MM stands
for minute, SS stands forsecond. Similar to the previous method, once Current
Month TOU is transferred to Prior Month TOU, all values from Current Month
TOU will be cleared and reset to 0.

4.7 Power Quality Event Logging and Waveform Capture
Power Quality Event Logging
When a power quality event happens, such as voltage sag and swell, Acuvim IIW
will record the event timestamp and the triggering condition. It can save up to
50,000 events.
1. Event Logging Data format
Timestamp (4 words) + Triggering Condition (1 word) + Rated Value (1 word) +
Threshold (1 word) + Half Cycle Count (1 word)
Each event has 8 words in total.
Event Time: W1: Year—High Byte; Month-Low Byte; W2:Day-High Byte, Hour—
Low Byte; W3:Minute—High Byte; Second—Low Byte; W4: Millisecond
Triggering Condition: W5—Voltage Sags or Voltage Swells 0: logging disabled;
Bit0: 1 – u1 voltage sag, 0 – no u1 voltage sag;
Bit1: 1 – u2 voltage sag, 0 – no u2 voltage sag;
Bit2: 1 – u3 voltage sag, 0 – no u3 voltage sag;
Bit3: 1 – u1 voltage swell, 0 –u1 no voltage swell;
Bit4: 1 – u2 voltage swell, 0 –u2 no voltage swell;
Bit5: 1 – u3 voltage swell, 0 –u3 no voltage swell;
Rated Value: W6—Voltage rated value;
Threshold: W7—Threshold for voltage sag and swell.
Half Cycle count: W8 (Voltage Swell: 0; Voltage Sag: 4—200)
2. Logging Events
The event logging feature can log 50000 events. If the 50000 events are full, no
more events will be logged even if the triggering condition happens. The user
89
must clear the event log, and then the logging will log the new event. When
the log is cleared, the new event will be logged from the first event happening.
There will be no data loss after the power is off.
3. Event Logging Triggering Conditions
1)Voltage Sag
When any phase of the three phase voltage is lower than the set value (voltage
rated value x threshold %), there will be a voltage sag event. When one phase
voltage sag happens, the other phase will not respond to voltage sag event
logging. Only when all of the phases voltage restore back to normal, a new
voltage sag event will be responded.
2)Voltage Swell
When any phase of the three phase voltage is higher than the set value (voltage
rated value x threshold %), there will be an Voltage Swell event. When one
phase Voltage Swell happens, the other phase will not respond to Voltage Swell
event logging. Only when all of the phases voltage restore back to normal, a
new Voltage Swell event will be responded.
Note:
The following figure depicts how to set the parameters for Power Quality Event
Logging and Waveform Capture. In the parameter settings, Voltage Sag and
Voltage Swell share the same voltage rated value. The parameters for event
logging includes: voltage rated value, voltage sag threshold, voltage sag half
cycle count and voltage swell threshold. Those parameters also fit voltage sag
waveform capture. The other triggering conditions for Waveform Capture can
be set when necessary. When the Waveform Capture triggering by Voltage Sag
and Voltage Swell is enabled, the corresponding event log and waveform will be
recorded when Voltage Sag or Voltage Swell happens.
90
Fig. 4-12
4. Event Log Retrieve
When a new event log commences, the newest event number address
(0X8CFDH)contains the newest event number. When the log is being retrieved,
the starting event log number (0X8CFEH) and the event quantity for each
retrieve (0X8CFF) must be set correctly. It must be ensured that the starting
number of event log should equal or smaller than the newest log number.
When setup is correct, reading registers 0X8D00H—0X8D4FH will acquire the
event log data. Each time a maximum of 10 logged events can be retrieved. The
event log retrieve page is in the figure below. The Modbus register address of
the event log is in the table below (see details in Chapter 6).

Waveform Capture
Acuvim IIW can record 100 groups of voltage and current waveform data at a
sampling rate of 64 points per cycle. It provides the captured waveform of 10
cycles before and after the triggering point (including U1,U2,U3,I1,I2,I3). The
triggering condition is settable.

10 I1 waveforms, 10 I2 waveforms, 10 I3 waveforms.
After triggering point 10 U1 waveforms, 10 U2 waveforms, 10 U3 waveforms, 10
I1 waveforms, 10 I2 waveforms, 10 I3 waveforms.
2. Waveform Capture Group
Waveform Capture can log up to 100 groups of waveform data. When the 100
group data is full, it does not respond to any waveform triggering condition.
Only when all the waveform data is reset / emptied, waveform capturing
function will be normal. When the waveform data is emptied, new waveform
data starts from the 1st group. The waveform data will not be lost when the
power is off.
Note: since the amount of each waveform group data is large, it takes more time
to write into the flash memory. Therefore, Waveform Capture only responds to
one triggering condition at one time. During the process of writing data into the
flash memory, it does not respond to new triggering condition. After the process
of memory writing, it will respond to new waveform triggering condition.
3. Waveform Capture Triggering Condition
1) Manual Triggering
Manually trigger one group waveform capture.
94
2) DI Triggering
DI Triggering must fulfill the following two conditions at the same time.
•IO modules with the logical address of 1 (AXM-IO11, AXM-IO21, AXM-IO31).
•DI channel type is set as “State”.
The Modbus address assigns two bits for the DI channel. When they are set
as “00”, it means DI Triggering Disabled; “01” means DI Triggering will be
implemented when DI state changes from OFF to ON; “10” means DI Triggering
will be implemented when DI state changes from ON to OFF; “11 “means DI
Triggering will be implemented when DI state has any change.
3) Voltage Sag Triggering
As mentioned in Voltage Sag event logging, when Voltage Sag Triggering
Waveform is enabled, both event logging and waveform capture will be
implemented at the same time once a voltage sag happens.
4) Voltage Swell Triggering
As mentioned in Voltage Swell event logging, when Voltage Swell Triggering
Waveform is enabled, both event logging and waveform capture will be
implemented at the same time once a voltage swell happens.
5) Over-current Triggering
When Over-current Triggering is enabled, if any phase of the three phase
current is higher than the set value (rated value x thredshold %), the waveform
capture will be implemented. If one phase is over-current, any other phase overcurrent cannot implement the waveform capture. Only when all of the phase
current restore back to normal, waveform capture will be responding.
4. Waveform Capture Retrieve
Because of large quantity of saved waveform, waveform retrieving window
use 64 addresses to make retrieving data easier, which keeps consistent with
95
recording points of one period. There are two retrieving methods, one retrieve
waveform record reasons, another retrieve all data of one group waveform. Two
methods are shown below.
First retrieving method is only retrieving waveform record reasons.
When 0x8E01H (Waveform Group Number) is set to 0, waveform record reason
can be retrieved from data retrieving window, by changing Waveform Group
Number for Retrieving (8E00H). Waveform record reason is 16 bytes and data
window are 64 bytes, so that is the reason why each retrieving access include 4
group records.
For example, if the total number of Waveform Group Number for Retrieving is
19, the by this method, only through 5 times retrieving, all 20 groups waveform
can be retrieved. Before retrieving, user should write 0 to 8E01H, and 1 to 8E00H,
while at first time retrieving addresses from 8E00 to 8E43, these window data
are the reasons of waveform group 1, 2, 3, 4. After retrieving, Waveform Group
Number for Retrieving (8E00H) will automatically update to 5. While at second
time retrieving addresses from 8E00 to 8E43, these window data are the reasons
of waveform group 5, 6, 7, 8. Waveform Group Number for Retrieving (8E00H)
will stop increasing after the value reaches 17.
Note: Unless user retrieves all data from 8E00H to 8E43H in one time, Waveform
Group Number for Retrieving (8E00H) will automatically add 4, otherwise
Waveform Group Number for Retrieving (8E00H) will keep present value if only
retrieving partial data. Waveform Group Number for Retrieving (8E00H) will stop
increasing while value reaches Newest Waveform Group Number. If the value
added 4, the value will be larger than Newest Waveform Group Number.
Second retrieving method is retrieving all waveforms data. When 0x8E01H
(Waveform Group Number) is set to 1~121, each time only one group data of
each number will be retrieved, then Waveform Group Number for Retrieving
(8E01H) will automatically add 1 after retrieving. At next time, new Waveform
96
Group Number will be retrieved. Waveform Group Number will stop increasing
after value reach 121.
Note: The range of 0x8E01H is 0~121, within setting range, windows
(8E04H~8E43H) are corresponding to waveform data.
0: Only retrieving waveform record reasons
1: Time and reasons of waveforms
2~11: Each waveform number of ten waveforms before U1 waveform is
triggered
12~21: Each waveform number of ten waveforms before U2 waveform is
triggered
22~31: Each waveform number of ten waveforms before U3 waveform is
triggered
32~41: Each waveform number of ten waveforms before I1 waveform is
triggered
42~51: Each waveform number of ten waveforms before I2 waveform is
triggered
52~61: Each waveform number of ten waveforms before I3 waveform is
triggered
62~71: Each waveform number of ten waveforms after U1 waveform is triggered
72~81: Each waveform number of ten waveforms after U2 waveform is triggered
82~91: Each waveform number of ten waveforms after U3 waveform is triggered
92~101: Each waveform number of ten waveforms after I1 waveform is triggered
102~111: Each waveform number of ten waveforms after I2 waveform is
triggered
112~121: Each waveform number of ten waveforms after I3 waveform is
97
triggered
Note: Unless user retrieves all data from 8E00H to 8E43H in one time, Waveform
Group Number for Retrieving (8E01H) will automatically add 1, or Waveform
Group Number for Retrieving (8E01H) will keep present value if only retrieving
partial data.

5. Relationship between voltage or current waveform value and real value
The relationship between voltage waveform value and real value:
Real Value (Unit: V) = Waveform Value / 37.59105
The relationship between current waveform value and real value:
Real Value (Unit: A) = Waveform Value / 1683.153
When users select 333mV Voltage type CT,real Value(Unit :A) = Waveform
Value/15869.87.
The voltage and current value obtained from the waveform are the PT or CT
secondary side value.
The waveform capture retrieve page is shown in Figure 4-14.

4.8 Seal Function
The panel with seal, which has sealed key control, is different with one without
seal. When the seal is in opened status, functions are same like normal meters.
But when the seal is in sealed status, some functions of meters, which include
parameters blocked by seal and optional parameters, will be blocked. These
parameters can still be accessible by keys and communication way if they can
be accessed before, but in sealed status, these parameters cannot be modified
by keys or communication way any more.
Addresses about seal function are 101EH and 101FH.
Address 101EH is about parameters blocked by seal, which can be configured
by users. These setting will be valid only when seal is in sealed status.
Address 101FH is about if seal function is valid. When the panel is normal one,
or the seal panel is in invalid sealed status, this address will show seal is open.
When the seal is valid, this address will show sealed status and corresponding
parameters will be blocked.

5.1 IO Modules
5.1.1 The Purpose of IO Modules
The standard Acuvim II meter base does not have any built-in IO functions.
However, with the addition of the extended modules, multiple IO options can
be added. These functions include digital input, pulse counter, relay output,
analog output, analog input, etc.
There are three types of IO modules, AXM-IO1, AXM-IO2 and AXM-IO3.
Please note that a maximum of 3 modules may be attached to the meter. If a
communication module is used, it must be installed on the back of the meter
first before any IO modules are attached. No more than 2 of the same type IO
modules can be attached. According to the diference in communication with
Acuvim II meter, each type of IO module also has two modes, logic NO.1 and
logic NO.2. This means, two of each type of IO module can be linked to the
Acuvim II meter simutaneously (one being logic NO.1 and the other being logic
NO.2).
The AXM-IO1 module is composed of:
6 digital inputs (DI) -- Each digital input can be used to detect remote signals,
or be used as an input pulse counter. When it is used to detect remote signals,
it also can enable SOE(sequence of events), recording the event and time of the
event.
2 relay outputs (RO) -- Can be used for controlling or alarming. Each of the relay
outputs work in the same mode. When it operates in controlling mode, there
are two output options; latching and pulse. When it operates in alarm mode, it
has only one latching output mode.
24V isolated power supply -- Used as an auxiliary power supply for digital
inputs.
108
The AXM-IO2 module is composed of:
4 digital inputs (DI) -- Each digital input can be used to detect remote signals,
or be used an input pulse counter. When it is used to detect remote signals it
can also enable SOE(sequence of events), recording the events and time of the
events.
2 analog outputs (AO) -- Can output analog voltage or analog current. When
it outputs analog voltage, the range of voltage is from 0 to 5V or from 1 to 5V.
When it outputs analog current, the range of current is from 0 to 20mA or from
4 to 20mA.
2 digital outputs (DO) -- Can be used in alarm mode or energy pulse output
mode. Both of the digital outputs work in the same mode. When it operates in
energy pulse output mode, it can output various types of energy.
The AXM-IO3 module is composed of:
4 digital inputs (DI) -- Each digital input can be used to detect remote signals, or
be used as an input pulse counter. When it is used to detect remote signals it
can also enable SOE(sequence of events), recording the events and time of the
events.
2 relay outputs (RO) -- Can be used for controlling or alarming. Each of the relay
outputs work in the same mode. When it operates in controlling mode, there
are two output options; latching mode and pulse . When it operates in alarm
mode, it has only one latching output mode.
2 analog inputs (AI) -- Can detect input analog voltage or analog current. When
it detects input analog voltage, the range of voltage is from 0 to 5V or from 1 to
5V. When it detects input analog current, the range of current is from 0 to 20mA
or from 4 to 20mA.

24V Isolated Power Supply:
To simplify and make more convenient for the end user, there is a DI auxiliary
power supply provided in AXM-IO1 module. The voltage of the DI auxiliary
power supply is 24Vdc (1W). This power supply can NOT be used for other
purposes.
Figure 5-12 shows the function of IO modules, which is displayed in the utility
software as follows, where AXM-IO12 (AXM-IO1 module in logic NO.2), AXMIO22 (AXM-IO2 module in logic NO.2) and AXM-IO32 (AXM-IO3 module in logic
NO.2) are linked to Acuvim II meter.
120
Fig 5-12 functions of IO modules
5.1.6 Detection of Remote Signals
The digital input circuit can be set to detect remote signals.
a. Detection of Remote Signals
When digital input circuit detects a qualified voltage input, it will show “1” on
screen and “ON” in utility software. Otherwise, it will show “0” on screen and “OFF”
in utility software.
121
Fig 5-13 showing DI state on screen
b. Record of SOE
When the digital input circuit is set to detect remote signals, the recording
function of SOE can be enabled. Therefore, when the remote signals change,
the IO module can record this information accordingly.
SOE Record: including “4399H to 4439H” address registers. “4399H to 4438H”
address registers record 20 groups of SOE records. “4439H” records the IO
module which generates the SOE records. For example, if register “4439H” is 1,
the 20 groups of SOE records are all generated by AXM-IO11 (AXM-IO1 module
in logic NO.1).
The 20 groups of SOE records are arranged based on time. When more than 20
groups of SOE records are generated, the records will begin at the first one.
When the Acuvim II meter is powered on, the SOE begins to record immediately.
The data in the SOE records will not be lost if the meter is powered off. When
the enabled SOE function is changed, the records will be lost.
122
All groups of SOE records are in the same format. Take the first group of SOE
records for example, “4399H to 439fH” registers record the time information,
including year, month, day, hour, minute, second and millisecond. “43a0H”
register records the state information, which is an unsigned integer, where bit 0
records DI1 state, bit 1 records DI2 state, and so on. For example, if “43a0H” is “1”,
it means that DI1 is “1”, and others are all “0”.
Note: If one of digital input circuits is set to be a pulse counter when the IO
module is SOE enabled, then the counterpart bit of “43a0H” register will always
be “0”.
Data of SOE records can only be read by the utility software, it cannot be read
on screen.
Figure 5-14 shows the data information of SOE records of AXM-IO12 (AXM-IO1
module in logic NO.2) read by the utility software.
Fig 5-14 data information of SOE records read by the utility software
123
c. Parameter Setting of Detection of Remote Signals
Take parameter setting of AXM-IO11 (AXM-IO1 module in logic NO.1) for
example.
“109eH” register: this register is an unsigned integer, where bit0 determines
DI1’s working mode, bit1 determines DI2’s working mode, and so on. If the bit
is “1”, then the DI circuit is set to be a pulse counter. Otherwise, the DI circuit is
set to detect remote signals. Figure 5-13 shows the parameter setting of digital
input circuits.
“101bH” register: this register is an unsigned integer, it determines that which
IO module will be SOE enabled. If register is “0”, then any IO module is SOE
disabled. If register is “1”, then AXM-IO11 (AXM-IO1 module in logic NO.1) is SOE
enabled. If register is “2”, then AXM-IO21 (AXM-IO2 module in logic NO.1) is SOE
enabled. If register is “3”, then AXM-IO31 (AXM-IO3 module in logic NO.1) is
SOE enabled. If register is “4”, then AXM-IO12 (AXM-IO1 module in logic NO.2) is
SOE enabled. If register is “5”, then AXM-IO22 (AXM-IO2 module in logic NO.2)
is SOE enabled. If register is “6”, then AXM-IO32 (AXM-IO3 module in logic
NO.2) is SOE enabled. Only one IO module can be SOE enabled at one time. If
the IO module is not linked to the Acuvim II power meter, then there is no need
to enable SOE function in the software.
Figure 5-15 shows the parameters setting of IO module’s SOE function.
124
Fig 5-15 parameters setting of IO module’s SOE function
5.1.7 Pulse Counter
The digital input circuit can also be set to count pulses.
Recorded number of pulses: including “4349H to 4380H” address The “4349H to
4380H” registers record 28 groups of individual number of individual number
of pulses. This includes 6 groups of records for AXM-IO11 (AXM-IO1 module in
logic
125
NO.1), 4 groups of records for AXM-IO21 (AXM-IO2 module in logic NO.1), 4
groups of records for AXM-IO31 (AXM-IO3 module in logic NO.1), 6 groups of
records for AXM-IO12 (AXM-IO1 module in logic NO.2), 4 groups of records for
AXM-IO22 (AXM-IO2 module in logic NO.2) and 4 groups of records for AXMIO32 (AXM-IO3 module in logic NO.2) in sequence. One group of records is
an unsigned long integer, for example, “4349H to 434aH” registers record the
number of pulses for DI1 circuit of AXM-IO11 (AXM-IO1 module in logic NO.1).
Figure 5-16 shows the recorded number of pulses read on screen.
Fig 5-16 recorded number of pulses read on the screen
Figure 5-17 shows the recorded number of pulses read by the utility software.
126
Fig 5-17 recorded number of pulses read by the utility software
Parameter Settings for Counting Input Pulses:
Take AXM-IO11 (AXM-IO1 module in logic NO.1) for example.
1. “109eH” register: if the bit is set as “1”, the counterpart digital input circuit is
set to be a counter of input pulses.
2. “109fH” register: this register is an unsigned integer. If this register is A , and
the digital input circuit is set to be a pulse counter, then the real number of
pulses counted by this DI circuit will be as follows:
127
Real number of pulses = A × Recorded number of pulses.
For example, if A=20, the recorded number of pulses counted by DI1 circuit of
AXM-IO11 is 100 (4349H to 434aH registers), then the real number of pulses is
20×100=2000.
The parameter setting is shown in Figure 5-13.
5.1.8 Relay Output
Relays in IO modules can work in two different modes, one is controlling mode,
and the other is alarm mode. For controlling mode, relays can be switched on
and off directly. For alarm mode, the action of relays is controlled by whether
the alarm has occurred or not.
There are two mode selections for relay output, one is latching, and the other
is pulse. For the latching mode, the relay can be used to output two status on
or off. For the pulse mode, the output of the relay changes from off to on for a
period of time and then goes off. The period can be set from 50 to 3000ms.
Note: when relay is working in alarm mode, the default output mode is latching
mode.
a. Display of Relay State
If relay state is “ON”, it means that relay is switched on. If relay state is “OFF”, it
means that relay is switched off.
Figure 5-18 shows the status of relays read on screen.
Figure 5-12 shows the status of relays read by the utility software.
128
Fig 5-18 status of relays read on screen
b. Parameter Setting
Take AXM-IO11 (AXM-IO1 module in logic NO.1) for example.
“RO working mode (10a0H)” register: this register determines the working
mode of relays. If the register is “0”, then RO1 and RO2 will work in controlling
mode. If the register is “1”, then RO1 and RO2 will work in alarm mode.
“RO output mode (10a1H)” register: this register determines the output mode
of relays. If the register is “0”, then RO1 and RO2 will work in latching output
mode. If the register is “1”, then RO1 and RO2 will work in pulse output mode.
“RO pulse width (10a2H)” register: when the relays are working in pulse
mode, this register determines the period of time which can be set from 50
to 3000ms. For example, if this register is “100”, the relay (RO1 or RO2) will be
switched on for 100ms after receiving ON instruction and then be switched off.
The parameter setting is shown in Figure 5-13.
129
5.1.9 Digital Output
There are two mode selections for the digital output circuit; one being alarm
mode, and the other being energy output mode. For alarm mode, action of
digital output circuit is controlled by whether the alarm is triggered or not. For
energy output mode, digital output circuits can output various types of energy,
such as import active energy, export active energy, import reactive energy and
export reactive energy. When outputting energy pulses, pulse width can be set
from 20 to 1000ms. The minimum interval between two pulses is 20ms.
Parameter Setting:
Take AXM-IO21 (AXM-IO2 module in logic NO.1) for example.
“DO working mode (10a5H)” register: this register determines the working
mode of DO circuits. If the register is “0”, then DO1 and DO2 will work in energy
output mode. If the register is “1”, then DO1 and DO2 will work in alarm mode.
“DO pulse width (10a6H)” register: when DO circuits work in energy output
mode, this register determines the width of energy pulses.
“DO1 output type (10a7H)” register: when DO circuits work in energy output
mode, this register determines the energy output type for DO1. If this register
is “0”, DO1 outputs nothing. If this register is “1”, DO1 outputs import active
energy. If this register is “2”, DO1 outputs export active energy. If this register
is “3”, DO1 outputs import reactive energy. If this register is “4”, DO1 outputs
export reactive energy.
“DO2 output type (10a8H)” register: when DO circuits work in energy output
mode, this register determines the energy output type for DO2. The value of
this register is defined as the same as “DO1 output type” register.
130
“DO1 output type” register and “DO2 output type” register can be set to the
same value or not.
The parameter setting is shown in Figure 5-19.

5.2 Ethernet Module (AXM-NET)
5.2.1 Introduction to Ethernet
Ethernet was originally developed by Xerox and then developed further by
Xerox, DEC, and Intel. Ethernet uses a Carrier Sense Multiple Access with
Collision Detection (CSMA/CD) protocol, and provides transmission speeds up
to 10 Mbps.
Now Ethernet stands for LAN with CSMA/CD protocol.
Ethernet is the most current communication standard in LAN. This standard
defines the used type of cable and the method of Signal processing in LAN.
5.2.2 Function Description of Ethernet module
Please read appendix of technical data and specifications of Ethernet module
before using.
﹡ The Ethernet module supports Modbus-TCP protocol. It is used as a server,
the default value of the protocol port is 502, and the user defined range of the
protocol port is 2000~5999. The device address is the same as the meter.
﹡ The Ethernet module supports SMTP protocol. It has an email function and
supports “Send mail for timing” mode and “Send mail for event” mode.
﹡ The Ethernet module supports HTTP protocol. It is used as an HTTP server, the
default value of the protocol port is 80, and the scope of the protocol port is
6000~9999.
* The Ethernet module supports SNMP protocol. It is used as a SNMP agent,

5.2.10 Description of Modbus-TCP protocol
The Modbus-TCP protocol is used for communication in Ethernet modules. The
protocol sets up master/slave link in Ethernet. First, master device (client) sets up
TCP link with slave device (server). Second, master device sends request frame
to slave device, and slave device receives request frame and returns response
frame to master device. Figure 5-41 displays working mode of Modbus-TCP
protocol.

d. Data Field
The data field is constructed using sets of two hexadecimal digits, in the range
of 00 to FF hexadecimal. The data field of messages sent from a master to slave
devices contains additional information which the slave must use to take the
action defined by the function code. This can include items like discrete and
register addresses, the quantity of items to be handled, and the count of actual
data bytes in the field. For example, if the master requests a slave to read a
group of holding registers (function code 03), and the data field specifies the
starting register and how many registers are to be read. If the master writes to
a group of registers in the slave (function code 10 hexadecimal), the data field
specifies the starting register, how many registers to write, the count of data
bytes to follow in the data field, and the data to be written into the registers.

5.3 ProfiBus Module (AXM-PRO)
5.3.1 Introduction of PROFIBUS Technology
PROFIBUS (Process Field bus) is an international field bus standard which is
widely used in automation technology of manufactures and flow industry. It is
a widely used, open digital communication system, which is suitable for highspeed, time-critical, and high reliability communications.
PROFIBUS is one kind of open style field bus standard which is promoted by
SIEMENS Corporation. In 1989, it became the German standard DIN19245, in
1996, it became the European standard EN50170, in 1999 it was accepted as
part of the international standard IEC61158 and in 2001 it became the Chinese
national standard JB/T 10308.3-2001 for field bus of machinery industry
controlling systems.
There are 3 types of PROFIBUS: PROFIBUS-DP (Decentralized Periphery),
PROFIBUS-PA Process Automation) and PROFIBUS-FMS (Field bus Message
Specification). ALL types follow the same protocol.
With optimized, high-speed, low-cost communication links, PROFIBUS-DP
is especially used in automatic controlling systems and equipment level
decentralized I / O communication. It can meet real-time response, stability and
reliability of equipment level and distributed controlling systems.
The PROFIBUS module uses PROFIBUS-DP (V0) protocol.
5.3.2 PROFIBUS module application notes
Please read appendix of technical data and specifications of PROFIBUS module
before using it. In addition, please read the communication addresses of
MODBUS protocol, which are the communication addresses for the PROFIBUS
188
module as well.
* The PROFIBUS module can only be used as slave in PROFIBUS network. Its
slave address ranges from 0 to 126, which can only be set by the panel. If the
address is changed, it will take effect immediately.
* The PROFIBUS module’s baud rate can be adaptive between 9.6Kbps to
12Mbps in PROFIBUS network.
* The PROFIBUS module terminals should be connected properly to avoid
problems during installation.
* Please read GSD file of the PROFIBUS module carefully before using. The GSD

The bus terminal is composed of three resistors and connection wire, where Vp
is the supply positive voltage and DGND is the Digital Ground. When the bus is
idle, the bus terminal makes the data P level higher than data N, so the bus’s idle
signal is always 1.
193
5.3.8 Address Setting
The PROFIBUS module can only be used as a slave in the PROFIBUS network.
Its slave address ranges from 0 to 126, which can only be set by the front panel
of the meter (in SYS sub menu of Acuvim II Setting menu). If the address is
changed, it will take effect immediately.
Figure bellow shows the address setting of PROFIBUS module.

5.3.9 Baud Rate
The PROFIBUS module’s baud rate can be adaptive between 9.6Kbps to 12Mbps
in PROFIBUS network.
194
5.3.10 GSD Files
A PROFIBUS-DP master can exchange data with various slave devices. In order to
indentify a slave device, it is necessary to obtain the technical data of the device
itself. The file where the data is described is called Device Description Data File
(GSD).
Because of the importance of GSD file, please read it carefully before using the
PROFIBUS module. The GSD file is provided in pure text format with detailed
comments.
 As a DP slave device, the PROFIBUS module supports protocol of V0 revision.
 The PROFIBUS module’s data interface is a 16 word input/output interface.
5.3.11 Information Exchange
A variety of information from the Acuvim II meter can be transmitted by the
PROFIBUS module, such as electrical quantities and other parameters. The basic
communication method of the Acuvim II meter is RS-485, which uses protocol
of MODBUS-RTU. In order to use the same address lists as MODBUS-RTU, the
communication formats of PROFIBUS-DP is categorized in the same way as
MODBUS-RTU.
It is recommaneded to refer to the communicaion part of the Acuvim II
manual (Chapter 6) for the list of MODBUS-RTU addresses, function codes, the
relationships between values, etc. Some examples are:
1. There are various function codes, such as 01H, 02H,03H, 05H,10H, for the
various categorized parameters. Different function codes have different formats
of query and response frames.
2. There is a specific relationship between numerical value in register of Acuvim
195
II meter and the real physical value.
3. Different parameters may have different data length and data type.
These three points are also suitable for the PROFIBUS-DP protocol in PROFIBUS
module.
Note: the following “communication formats”are suitable for the application
data, but not for the PROFIBUS-DP’s frame characteristic data.
Function codes, such as 01H, 02H and 03H, are inquiry commands. For users to
quickly switch the inquiry contents, we define 8 channels named 1 to 8 , in order
to update data more quickly.
5.3.12 Format of function code 01H
Function code 01H is used to read relay status in MODBUS-RTU. In PROFIBUS-DP,
the format of function code 01H is defined as follows:

5.4 RS485 Module (AXM-485)
5.4.1 Communication Parameters Setting
RS485, also known as EIA-485, is a telecommunications standard for binary serial
communications between devices. RS485 is the most versatile communication
standard in the standard series defined by the EIA, and it is currently a widely
used communication interface in data acquisition and control applications
where multiple nodes communicate with each other.
The RS485 signals are floating and each signal is transmitted over a differential
signal + line and a differential signal - line. The RS485 receiver compares the
voltage difference between both lines, instead of the absolute voltage level on
a signal line. If the differential signal + and differential signal - lines are twisted,
better communication performance can be achieved. The twisted pair adds
immunity to fight noise. If high noise immunity is needed, often a combination
of twisting and shielding is used. For example, shielded twisted pair or foiled
twisted pair networking cables.
5.4.2 Function Description of RS485 module
AXM-RS485 module uses RS485 serial communication and the Modbus-RTU
protocol, just like the onboard RS485 port of the Acuvim II series meter. It
provides a second RS485 port for serial communication, and it can be working
with the onboard RS485 serial communication simultaneously.
The terminals of communication are A, B, and S. A is differential signal +, B is
differential signal -, and S is connected to the shield of the twisted pair cables.
• Up to 32 devices can be connected on a RS485 bus without repeaters.
205
• Use good quality shielded twisted pair cable, AWG22 (0.5mm2) or higher.
• The overall length of the RS485 cable connecting all devices should not
exceed 1200m (4000ft).
• Every A(+) should be connected to A(+), B(-) to B(-), or it will influence the
network, or even damage the communication interface.
• When using a long communication cable to connect several devices, an antisignal reflecting resistor (typical value 120Ω-300Ω/0.25W) is normally added
to the end of the cable beside the last meter if the communication quality is
distorted.

The RS485 module is linked to the meter by a communication plug. It also can
be linked to other extended modules.
1.Insert the installation clips to the counterpart of the meter, and then press the
RS485 module lightly, so linking is established.
2.Tighten the installation screws.
207
Note:
1. Install AXM-RS485 Module carefully to avoid damage;
2. Under no circumstances should any installation be done with the meter
powered on. Failure to do so may result in injury or death.
5.4.5 Connection Method
The RS485 module is using 2-wire, half-duplex communication mode, which is
the same as the one the onboard RS485 port is using. If the master does not
have RS485 communication port, a converter (such as a RS232/RS485 or a USB/
RS485 converter) will be required. Typical RS485 network topologies include
line, circle and star. The shield of each segment of the RS485 cable must be
connected to the ground at one end only.
Fig 5-65
The default baud rate of RS485 module is 38400 bps. Users can change the
baud rate in system settings S03 of the Acuvim II series meter.
208
The data format is start bit + 8n data bit + parity + stop bit. NON1, NON2, odd
and even can be selected for parity mode on S32 of Setting page of Acuvim
IIR and Acuvim IIE meter (Not support Acuvim II meter). NON1 represents
non-parity, single stop bit; NON2 represents non-parity, double stop bit; odd
represents odd-parity, single stop-bit; even represents even parity, single stop
bit; As is shown, the RS485 module’s parity is set as None 2.
Fig 5-66
Please note: if AXM-NET is used, RS-485 module’s parity (PAR2) must be set as
None1 in order to have the meter recognize the AXM-NET.

5.5 BACnet Module(AXM-BACnet)
5.5.1 BACnet Overview
The Building Automation and Control Network (BACnet), described in the
ANSI/ASHRAE Standard 135-1995, is one of the most widely used building
management systems protocols.
BACnet was designed to allow communication of building automation
and control systems for applications such as heating, ventilating, and airconditioning control, lighting control, access control, and fire detection systems
and their associated equipment. The BACnet protocol provides mechanisms for
computerized building automation devices to exchange information, regardless
of the particular building service they perform.
5.5.2 Introduction
The Acuvim II Series Power Meter has embedded BACnet IP communication, and
also has embedded BACnet MS/TP communication. It communicates in native
BACnet IP over Ethernet to seamlessly integrate with most building automation/
control systems, and communicating with the BACnet MS/TP via the RS485. The
Acuvim II Series Power Meter's BACnet IP and BACnet MS/TP has 56 predefined
BACnet objects that let you track up to 56 measurements.
The Acuvim II Series Power Meter has native BACnet/IP that lets it act as a
BACnet server in any BACnet application. The Acuvim II Series Power Meter’s
BACnet IP also comes with a Web interface that is very easy to browse the
parameter data by using a standard browser.
5.5.3 About BACnet Protocol
BACnet operates in a client-server environment. A client machine sends a
210
service request (message) to a server machine; once the service is performed
the results are reported back to the client machine. BACnet defines 5 groups
(or classes) of 35 message types. For example, one class contains messages for
retrieving and manipulating the object properties described above. An example
of a common service request in this class is "ReadProperty." When the server
machine receives this message from a client machine, it locates the requested
property of the requested object and sends the value to the client.
The BACnet protocol consists of Objects that contain different kinds of
information. Each Object has properties that contain data related to it. Below is
the example of an Object for Total Watts:
Object_Name, P_rms
Object_Type, AnalogValue
Object_Instance, 17
Present_Value, watt, tot (value in watts)
For more detailed information, visit the BACnet website at www.bacnet.org.
5.5.4 Using the Acuvim II Series Power Meter’s BACnet
Serial and Ethernet versions
There are a couple of different serial and Ethernet based-versions of BACnet.
The most common serial version is called BACnet MS/TP while the dominant
Ethernet version is BACnet/IP.
BACnet/IP has been developed to allow the BACnet protocol to use TCP/IP
networks. You could say that BACnet/IP is a way of hooking BACnet up to the
Internet and communicate with different Local Area Networks (LANs). This
enables system owners, facility managers, or even external suppliers to access
BACnet networks and manage their devices and systems remotely.

This chapter will mainly discuss how to handle the meter via the communication
port using software. It is highly recommanded that previous chapters be read
before moving onto Chapter 5, a familiarity with Modbus would also be helpful.
6.1 Modbus Protocol Introduction
ModbusTM RTU protocol is used for communication in Acuvim II series meters.
Data format and error check methods are defined in Modbus protocol. The half
duplex query and respond mode is adopted in Modbus protocol. There is only
one master device in the communication network. The others are slave devices,
waiting for the query of the master.
Transmission mode
The mode of transmission defines the data structure within a frame and the
rules used to transmit data. The mode is defined in the following which is
compatible with Modbus RTU Mode*.

Address Field
The address field of a message frame contains eight bits. Valid slave device
238
addresses are in the range of 0~247 decimal. A master addresses a slave by
placing the slave address in the address field of the message. When the slave
sends its response, it places its own address in this address field of the response
to let the master know which slave is responding.
Function Field
The function code field of a message frame contains eight bits. Valid codes are
in the range of 1~255 decimal. When a message is sent from a master to a slave
device the function code field tells the slave what kind of action to perform.

registers
05
Control Relay Output
Force relay state to "ON" or "OFF"
16
Press Multiple-Register
Place specific binary values into a series of
consecutive Multiple-Registers
Data Field
The data field is constructed using sets of two hexadecimal digits, in the range
of 00 to FF hexadecimal. The data field of messages sent from a master to slave
devices contains additional information which the slave must use to take the
action defined by the function code. This can include items such as register
addresses, the quantity of items to be handled, and the count of actual data
bytes in the field. For example, if the master requests a slave to read a group of
holding registers (function code 03), the data field specifies the starting register
and how many registers are to be read. If the master writes to a group of
registers in the slave (function code 10 hexadecimal), the data field specifies the
starting register, how many registers to write, the count of data bytes to follow

in the data field, and the data to be written into the registers.
If no error occurs, the data field of a response from a slave to a master contains
the data requested. If an error occurs, the field contains an exception code that
the master application can use to determine the next action to be taken. The
data field can be nonexistent (of zero length) in certain kinds of messages.
Error Check Field
Every message includes an error checking field which is based on the Cyclical
Redundancy Check (CRC) method. The CRC field checks the contents of the
entire message. It is applied regardless of any parity check method used for
the individual characters of the message. The CRC field is two bytes long,
containing a 16-bit binary value. The CRC value is calculated by the transmitting
device, and is appended to the message.
The receiving device recalculates the CRC value during reception of the
message, and compares the calculated value to the actual value it received in
the CRC field. If the two values are not equal, an error will be reported. CRC
calculation is first started by preloading the whole 16-bit register to 1’s. The
process begins by applying successive 8-bit bytes of the message to the current
contents of the register. Only the eight bits of data in each character are used
for generating the CRC. Start and stop bits, and the parity bit, do not apply
to the CRC. When generating the CRC, each 8-bit character is exclusive ORed
with the register contents. The result is shifted towards the least significant bit
(LSB), with a zero filled into the most significant bit (MSB) position. The LSB is
extracted and examined, if the LSB equals to 1, the register is exclusive ORed
with a preset, fixed value; if the LSB equals to 0, no action will be taken. This
process is repeated until eight shifts have been performed. After the last (eighth)
shift, the next 8-bit byte is exclusive ORed with the register's current value,
and the process repeats for eight more shifts as described above. After all the
240
bytes of the message have been applied,the final contents of the register, which
should exchange the high-byte and the low-byte, is the CRC value. When the
CRC is appended to the message, the low-order byte is appended first, followed
by the high-order byte.

Important Note: Regions from “System parameters settings” to “Data logging
3 settings” are the regions that can be set and modified. Please follow these
guidelines when communicating with the meter.
247
1. When function code 10H is used, one communication command can only
modify contents in one region, such as “System parameters settings”, ”System
status parameter”, “Date and Time table”, “Over/under limit alarming-Global
settings”, “Over/under limit alarming-Single settings”, “I/O Modules settings”,
Data logging 1 settings,Data logging 2 settings,Data logging 3 settings. It can
not be accomplished in one communication order to modify contents in both of
two or more regions above.
2. When function code 03H is used, the rules and limitations described above
will not be applied.
6.3.1 System Parameter Setting

Note:
1. When reversed phase sequence (51) is selected, whether the value of
comparison mode or setpoint value is set or not doesn’t affect alarm result and
angle of Ub to Ua will be recorded.
2. When DI (52~79) is selected, whether the value of comparison mode is set or
255
not doesn’t affect alarm result and as long as setpoint value is set to 1, 2 or 3.
1 stands for DI alarm is from OFF to ON, and recovery is from ON to OFF.
2 stands for DI alarm is from ON to OFF, and recovery is from OFF to ON.
3 stands for DI alarm from ON to OFF, and recovery is from OFF to ON, and
present DI status is recorded.

6.3.7 Data Logging
Data Logging Setting
In order to generate historical logs for the selected parameters, users should
program the meter so that selected parameters from the cooresponding
Modbus registers can be copied to the historical log record. Since certain
parameters occupy two registers, to supplement this, the programmable
settings for the historical logs contain a list of descriptors. Each descriptor lists
the number of Modbus registers for the specified parameter. By combining
these two lists, the historical log record can be interpreted.
For example: Registers 4002H and 4003H are programmed to be recorded by
the historical log. Since 2 registers are used, the corresponding descriptor is set
as 2. These registers program the log to record “Volts AN.”
The historical log programmable settings are comprised of 3 blocks, one for
each log. Each log works identical to each other; therefore, only historical log
1 is described here. All register addresses in this section are shown within the
address range of historical log 1.
1100H-11DFH (Historical Log 1)
11C0H-127FH (Historical Log 2)
1280H-133FH (Historical Log 3)

Interval
Registers: The number of registers to log in the record range from {0-117}. The
size of the record in memory is [12 + (Registers x 2)].
Sectors: The number of memory sectors allocated to this log. Each sector is
64kb in size. 100 sectors are available for allocation among the three historical
logs. Valid allocation range is from 0-100 (When the sector is set 0,this log is
disable).
Interval: The data capture interval for historical log records. Valid time interval
can be set from 0-1440 minutes. When the interval is set to 0, this log is disable.
2) Register List:
Registers: 1102H-1176H
Size: 1 or 2 register(s) per parameter, 117 available registers per historical log.
The register list controls which Modbus registers are recorded in each historical
log record. Since many parameters, such as Voltage, Energy, etc., take up more
than 1 register, multiple registers are allocated for those parameters.
278
For example: In order to record "Volts AN" into the historical log, Volts AN's
Modbus address (4002H and 4003H) are assigned and programmed to the log
record list so that information can be stored into the historical log registers.
• Each unused register item should be set to 0000H or FFFFH to indicate no
parameters are associated with them.
• The actual size of the record, and the number of items in the register list which
are used, is determined by the registers in the header.
• Valid register address ranges that can be recorded in the historical log registers
are 4000H-412BH, 4294H-42A8H, 4349H-4398H, 4500H-461BH.
3) Item Descriptor List:
Registers: 1177H– 11B1H
Size: 1 byte per item, 117 bytes (59 registers)
While the register list describes what to log, the Item descriptor list describes
how to interpret that information. Each descriptor describes how many Modbus
addresses are used to describe a parameter. Either 1 or 2 addresses will be used
for each parameter.
For example: If the first descriptor is 2, and the second descriptor is 1, then
the first 2 register items belong to the 1st descriptor, and the 3rd register item
belongs to the 2nd descriptor.
NOTE: As can be seen from the example above, it is not a 1-to-1 relation
between the register list and the descriptor list. A single descriptor may refer to
two register items.
4) Logging Timer setting
If data logging only record one period data, or only start from one specific time,
corresponding time and logging mode should be set then data logging can
work well.
279
Modbus address 11B2H is used as the logging mode select. When value is 0,
logging mode is set to mode1, without time setting. When value is 1, logging
mode is set to mode2, so 11B3H-11B5H (start year, month, day, hour, minute,
and second) and 11B6H-11B8H (end year, month, day, hour, minute, and
second) should be set. When value is 2, logging mode is set to mode3, so only
11B4H (hour) and 11B5H (minute) should be set. How data logging works is in
Chapter 4.

Max Records: The maximum number of records the log can hold given the
record size and sector allocation.
Used Records: The number of records stored in the log. This number will equal
the Max Records when the log has filled. This value will be set to 1 when the log
is reset.
280
Record Size: The number of bytes in this record, including the time stamp.
The record's format in the meter is: record number(4bytes)+ time stamp(6bytes)
+ [data1~dataN](2Nbytes) + CRC(2bytes).
First Record Time stamp: Time stamp of the oldest record.
Last Record Time stamp: Time stamp of the newest record.
Log Retrieval Block
The log retrieval block consists of 2 parts: the header and the window. The
header is used to verify the data shown within the requested log window. The
window is a sliding block of data that can be used to access any record in the
specified log.

Log type: The log to be retrieved. Write this value to set which log is being
retrieved.
0 -Historical Log 1
1 -Historical Log 2
2 -Historical Log 3
Records number: The number of records that fit within a window. This value is
settable, any number less than a full window may be used. This number tells the
281
retrieving program how many records to expect to be fetched in the window.
(record number x Record Size) = bytes used in the window. This value should be
((123 x 2) / Record Size), rounded down. The greater this number is, the faster
the retrieving speed is.
For example, with a record size of 50, the Records number = ((123 x 2) / 50)
=4.92 ~= 4.
Status: The status of the current window. Since the time to prepare a window
may exceed an acceptable Modbus delay (1 second), this acts as a ready status
flag to notify when the window is ready for retrieval. When this value indicates
that the window is not ready, the data in the window should be ignored.
Window Status is Read-only, any writes are ignored.
This value also indicates the memory erasing status when setting the date
logging settings.
bH Window is Ready
FFH Window is Not Ready
aaH memory is erasing
bbH memory erasing is finished
Offset: The offset of the record number of the first record in the data window
and the record number of the "first record time stamp". Setting this value
controls which records will be available in the data window. When the log is
retrieved, the first (oldest) record is “latched.” This means that offset 0 will always
point to the oldest record at the time of latching.
Window: The actual data of the records, arranged according to the above
settings.
Note: If the logging timer is disabled, the first recording sector will be erased
when the log is full. Therefore, user should not read the whole log when the
282
used record numer is near to the max record number. Under this condition,
user should read the "Used Records" field and compare it to the previous "Used
Records" field from the last reading before retrieving the information and
reading the window.
If the current "Used Records" field is greater than the "Used Records" field from
the last reading and if the "Offset" field is less than the difference between the
current and previous "Used Records" field, the first sector has been erased and
the difference between the "Used Records" field should be subtracted from the
recording number.
If the "Offset" field is greater than the difference between the current and
previous "Used Records" field, the "Offset" number should be subtracted from
the recording number.
To avoid this situation, user should read the log before it is almost full.
For example: Data logging 1 has 3 sectors and each has 448 records, and
the total records are 1344. If you press the "Read All" button when the
"Used Records" number is at 1340 and if the first sector is erased before the
information is transferred to the computer, the data stored in this sector is
erased permanently and cannot be retrieved. If the records from the first sector
can be retrieved before it gets erased, the new value of "Offset" will equal to the
original "Offset" field minus the value of the difference between the current and
previous "Used Records" field.
Data logging opration examples
The following example illustrates a data logging opertation. The example
makes the following assumptions:
• The log is Historical Log 1.
283
• The Log contains VAN, VBN, VCN (12 bytes),the interval is 1min, the sectors is
10,the registers is 6, the logging timer function is disabled.
• Retrieval is starting at record offset 0 (oldest record).
• No new records are recorded to the log during the log retrieval process.
a) Data logging settings
Now set the data log 1 according to the assumptions:
1. Set the data log with VAN, VBN, VCN, here we should set their modbus
address 0x4002,0x4003,0x4004,0x4005,0x4006 and 0x4007 to 0x1102, 0x1103,
0x1104, 0x1105, 0x1106 and 0x1107. And the discripter is 2,so set the 0x0202
and 0x0200 to 0x1177 and 0x1178.
2. The register is 6 and sector is 10, so we set 0x060A to 0x1100.
3. The interval is 1min , so set the 0x0001 to 0x1101.
4. The logging timer function is disabled, so set the 0 to 0x11b9.
b) Log Retrieval Procedure
The following procedure documents how to retrieve a single log from the oldest
record to the newest record.
1. Compute the number of records per window, as follows:
RecordsPerWindow = (246 \ RecordSize)=246\24=10.
2. Write the Records per window and Record offset, in this example set the
0x0A0B and 0x0000 to 0x6001d and 0x6002.
This step tells the meter what data to return in the window.
3. Read the record window status from 0x6001.
284
• If the Window Status is 0xFF, go to step 2.
• If the Window Status is 0x0B, Read the data window.
4. Read the data window and compute next Expected Record offset.
• Compute the next expected record offset by adding Records Per Window and
go to step 2.
• If there are no remaining records after the current record window, stop
reading.

Waveform Capture Data Retrieve Address
Waveform Capture includes timestamp, triggering condition, and waveform data.
Every group uses the same data format. Only one group of waveform is saved in
the registers. When retrieving the waveform, firstly write 1-8 group number into
0X801FH, then read the registers after it to acquire waveform corresponding to
the written group number.
The relationship between voltage waveform value and real value:
Real Value (Unit: V) = Waveform Value / 37.59105
The relationship between current waveform value and real value:
Real Value (Unit: A) = Waveform Value / 1683.153
When users select 333mV Voltage type CT,real Value(Unit :A) = Waveform
Value/15869.87.The voltage and current value obtained from the waveform are
the PT or CT secondary side value.

6.4.1 Overview
This document describes the DNP3.0 communications protocol employed
by Acuvim II Series Power Meter. This protocol can be selected for the serial
communication port which can consist of RS232/RS485. It is assumed that the
reader is familiar with the DNP3.0 protocol and serial communications in general.
This DNP3.0 is a reduced set of the Distributed Network Protocol Version 3.00,
and it gives enough functionality to get critical measurement from the Acuvim II
Series Power Meter. The DNP3.0 supports class0 object only. No event generation
is supported .This DNP3.0 is always act as a slave device.
313
6.4.2 Physical Layer
The physical layer supported by DNP3.0 must transmit or receive data in serial
mode. The data unit transferred will be 8 bits in length.
The port must be asynchronous half-duplex RS-485.
The data format supporting 8 bit data, 1 start bit, 1 stop bit, no parity.
The baud rate can be set to any supported value.
6.4.3 Data Link Layer
The Acuvim II Series Power Meter always acts as a Slave device .The device address
can be set from 0 to 65534. The link layer comply with the stand FT3 frame format.
The fixed length user data field is behind the fixed head. The link layer supports
Reset Link, Reset User and Read Link Status. In order to ensure the stability of
communication, it is recommended that you should better reset the link and reset
the user before communicate with the Acuvim II Series Power Meter.
The function code supported as follows:
Reset Link ( 0X00 ), Reset User ( 0X01 ), Link Status ( 0X09 ).
FT3 Frame Format:
An FT3 frame is defined as a fixed length header block followed by optional data
blocks. Each block has a 16-bit CRC appended to it. The header fields consist of 2
start octets, 1 octet length, 1 octet control, a destination address, a source address
and a 16-bit CRC appended to it.

6.4.4 Transport Layer
The pseudo-transport layer segments application layer messages into multiple
data link frames. For each frame, it inserts a single byte function code that
indicates if the data link frame is the first frame of the message, the last frame of
a message, or both (for single frame messages). The function code also includes a
rolling frame sequence number which increments with each frame and allows the
receiving transport layer to detect dropped frames.
6.4.5 Application Layer
The Acuvim II Series Power Meter implementation supports a subset of the
objects and application layer function codes. The Acuvim II Series Power Meter
will neither accept nor send multiple fragment application layer messages. The
Acuvim II Series Power Meter’s fragment size is fixed at 2k bytes.
Each application layer fragment begins with an application layer header followed
by one object header or object header and data combinations. The application
layer header contains an application control code and an application function
code. The application control code contains an indication if the fragment is
one of a multi-fragment message, contains an indication if an application layer
confirmation is requested for the fragment, contains an indication if the fragment
was unsolicited, and contains a rolling application layer sequence number. The
application layer sequence number allows the receiving application layer to
detect fragments that are out of sequence, or dropped fragments.
In the Acuvim II Series Power Meter, the DNP3.0 supports the Read function , the
Direct Operate function and the Direct Operate Unconfirmed function.
The Read function ( 0X01 )
The read function is the basic code used for requesting data objects from an
Outstation. Here this function is used for reading the measurement data from
315
the Power Meter. Learning more about the measurement data, please refer to the
Data Address Table. In this function, the qualifier could be selected contain 0X00,
0X01, 0X06.
The qualifier 0X00 refers that there two bytes called Range followed by, one is the
start address want to request, the second is the stop address, this Range would be
from 0 to 255.
The qualifier 0X01 indicates that the followed Range there are four bytes, the first
two is the Start Address want to be request, the last two is the Stop Address, the
two bytes consist of two 8-bit binary number , the low byte first, that the address
Range would be from 0 to 65535.
The qualifier 0X06 means read All data from the object with its respective
variations which would be list in the queue.
More about the message please see Message Layout, the detailed examples.
The Direct Operate function ( 0X05 )
The function is selects and sets or operates the specified outputs, the status of
the control points will be responded. Here this function is intended for resetting
the energy counters and the demand counters. These actions are mapped to
Objects 12 Variations 1, point 1 and point 2, there are seen as a control relay. The
relay must be operated On in 0 millisecond , and released Off in 1 millisecond .The
qualifiers 0X17 and 0X28 are supported for writing the energy reset and demand
reset. The examples will be shown in Message Layout.
The Direct Operate function ( 0X06 )
The function is selects and sets or operates the specified outputs but do not send
a response to the request. Here this function is intended for switching the DNP3.0
protocol to Modbus protocol using the same communication port. This switching
316
is seen as a control relay mapped into Object 12 Variation 1 and point 0 in the
Acuvim II series Power Meter. The relay must be operated with qualifier 0X17, code
3, count 0, with 0 millisecond On and 1millisecond Off. After sending the request
the current communication port will be changed to the Modbus protocol only.
The example will be shown in the Message Layout.
6.4.6 Error Reply
When meet the can’t recognize request , the unknown Object ,the unknown
variation ,the point unsupported , the unsupported function code , the
unsupported qualifier ,the unsupported range , the buffer overflow or any other
exception error , an error reply will be generate from the Acuvim II series Power
Meter to send to the requester station . The Internal Indicator field will reflect the
type of error.
