1.1 Description of the device
The three-phase energy meters WM3-6, WM3M6 (MID certified) are intended for energy measurements in three-phase electrical power network and can be used in residential, industrial and utility applications. Meters measure energy directly in 4-wire networks according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates active/reactive/apparent power and energy, current, voltage, frequency, power factor, power angle and frequency (for each phase and total sum) from the measured signals. This smart meter can also perform basic harmonic analysis (THDU, THDI). This enables quick overview of harmonic distortion either coming from a network or generated by the load. Microprocessor also controls LCD, LED, IR communication and optional extensions. Connecting terminals can be sealed up against non-authorised access with protection covers. They are built to be fastened according to EN 60715 standard.

1.2 Three-phase energy meters application
Energy meters have built-in optical (IR) communication port on the side as a standard. Special WM-USB adapter (size 1 DIN module) can easily be attached to it. It can be used for direct communication with a PC to change settings of devices without any communication installed. Energy meters could also be connected with iHUB-L1 or Bicom by optical communication (IR). Optional the meter can be equipped with the following communications:
RS485 serial communication with the MODBUS protocol, M-BUS serial communication,
Communication modules enables data transmission and thus connection of the measuring places into the network for the control and management with energy. Instead of communication modules, there can be also tariff input (option) or built-in pulse output (option). Tariff input provides measurement of two tariffs for selected energy registers. Pulse output is sending data to the devices for checking and monitoring consumed energy. On the housing there are only two terminals, thus only one functional extension is possible (serial communication, tariff input, pulse output).

3.1 Individual phase measurement unit
The microprocessor is used to process the voltage and current samples from the AD converter. It calculates the RMS voltage, RMS current, active and reactive power, U-I phase angle, first harmonic of voltage, first harmonic of current, the DC voltage, DC current, peak to peak voltage, peak to peak current, THD of voltage and THD of current. The internal temperature and supply voltage is measured also. Metering functions are done with the processing unit. There are four different energy counters, which can be configured each to measure one of seven different types of energy. For MID meters, this energy counters are configured only in production. For Non-MID counters they can be also reconfigured during use. These are:
Total Absolute Active Energy (kWh) Total Absolute Reactive Energy (kvarh) Total Absolute Apparent Energy (kVAh) Import Active Energy (kWh) Export Active Energy (kWh) Import Reactive Energy (kvarh) Export Reactive Energy (kvarh)
The energy register is a count of pulses. The number of CE units per pulse is a constant in the meter calibration data. Function add () adds the current interval’s power data to a “remainder” variable. If this variable is larger than one pulse, then the number of pulses is added to the energy register, and remainder variable is decreased by the number of CE units that represent the same amount of energy. Measuring values are averaged within 1 second and displayed on the LCD at the same interval. Parameters which can be shown are:
1 Energy registers:
I. Energy counter 1 (mandatory) II. Energy counter 2 III. Energy counter 3 IV. Energy counter 4
2 Actual measured values:
I. Active Power, total, ph1, ph2, ph3 II. Reactive Power, total, ph1, ph2, ph3 III. Apparent Power total, ph1, ph2, ph3 IV. Power Factor, total, ph1, ph2, ph3 V. Voltages U1, U2, U3 VI. Phase to phase voltages U12, U13, U23 VII. Frequency VIII. Current I1, I2, I3 IX. Power Angle total
Parameter cycling period is settable from 5 seconds to 60 seconds. Cycling period and the definition of parameters for LCD scrolling are configured via RS485 or IR communication.

For MID approved meters only active energy is approved – non resettable counters. The approved active energy counters are coded with the following codes: 1110 – Import Active Power, Tariff 1 1120 – Import Active Power, Tariff 2 1130 – Import Active Power, Tariff 1&2 1210 – Export Active Power, Tariff 1 1220 – Export Active Power, Tariff 2 1230 – Export Active Power, Tariff 1&2 1310 – Total Active Power, Tariff 1 1320 – Total Active Power, Tariff 2 1330 – Total Active Power, Tariff 1&2 Import/export is defined on the basis of sum of phase powers P1 + P2 + P3. If the sum of phase powers is positive, import register counts, if the sum of phase powers is negative, export register counts.
3.2 Display of device info
Energy meters have LCD display with following layout.
Energy counter displays (up to 4 counters) are displaying current energy counter settings (tariff, import/export/total, active/reactive/apparent), its value and actual activity (counting (A)/not counting ( )). Other displays are displaying actual value of measured quantity (P-W, Q-var, S, PF, U, f and I), direction of active energy flow (import / export), reactance (inductive / capacitive) and active tariff (regarding tariff input). Energy registers are displayed with resolution 7 + 1 (kWh, kvarh and kVAh). The meter can be set to Test measuring mode which displays energy registers with better resolution. The test mode is used for test purposes during type testing and test of meter constant during initial verification. After power off meter automatically goes back to normal operation.

Test output is provided as LED with number of impulses proportional to active energy. Pulse constant is 1000 imp/kWh. Optionally the S0 impulse output with the same constant can be used for active energy. Pulse output is defined to be (32 ± 2) ms long according EN 62053-31. Energy measurement is blocked for the currents less than 20 mA. The meter measures actual voltage and frequency. Current and power values are set to zero and there is no energy registration. No load condition is indicated with the LED on. If the supply voltage is too low, the energy measurements are also blocked and communication is disabled. LCD stops to cycle and displays only value of voltage.
3.3 Software functions
Identification – SW version can be read from LCD or using RS485 or IR communication. The check sum (CRC) of complete firmware is calculated and displayed during initialization and later it can be read from LCD Info menu or MODBUS registers. If CRC for code is changed and does not correspond to the initial CRC an ERROR is detected during startup and ERR 2 is shown on the LCD. This is checked after every restart of the meter. MID SW is separated from non MID SW – MID versions are 2.xx as non MID versions are 1.xx. The MID version uses a MID key that prevents the upgrade of software and modification of parameters related to energy measurement. Unlocking the key is possible only at special operating conditions which do not appear on the field. In case the MID meter is not locked the ERR 4 is shown on the LCD. The MID SW version counts the number of times the instrument was MID unlocked and the number could be read from the LCD ( 5.8.1.3 LCD Info menu). Calibration parameters can only be changed in production. They cannot be changed by upgrade or different processes. Special factory software is used to calibrate the parameters for current, voltage, phase angle and linearity. If these parameters were deliberately or accidentally changed, an error type 1 is detected and ERR 1 is shown on the LCD. Calibration parameters are checked every minute for consistency and if error is found, ERR 1 is immediately shown on LCD. It is possible to upgrade the firmware via factory software protocol. This option is available only for WM3-6 (non MID) type of meter. The number of upgrade is counted and it could be read from the LCD ( 5.8.1.3 LCD Info menu). There is an option for a password to protect the instrument. Password has four levels of protection. Meter has possibility of two level user defined password (4 characters from A to Z). Password Level 1 – enables resetting the counters (MID and non MID meters) and tariff setting (non MID meters). Password Level 2 – enables all available settings and resets. If meter password is forgotten, device serial number should be sent to Iskra, d.d. to receive device default password. WM3-6 supports MODBUS protocol. RTU mode is used. RTU messages start and end with a silent interval of at least 3,5 character times (t1-t2-t3-t4 as shown below). Each message is transmitted in a continuous stream. If a silent interval of more than 1.5 character times occurs before completion of the frame, the device flushes the incomplete message and assumes that the next byte will be the address field of a new message. Cyclic Redundancy Check (CRC) is used. All parameterization is done via communication with MiQen software (version 2.1 or later). WM3M6 (MID) has limited parameterization. Counter and tariff settings are not enabled. If these settings or any measuring relevant parameters on WM3M6 (MID) were tenaciously or accidentally changed, an error type 1 is detected and ERR 1 is shown on the LCD. Settings are checked every minute for consistency and if error is found, ERR 1 is immediately shown on LCD. Firmware allows also user defined parameterization software using MODBUS protocol with specified MODBUS registers.

3.4.3 Set device ModBus address
Non configured devices have the same factory Modbus address set to 33. One of the options for changing the Modbus address is the following. Holding the button for more than 6 seconds, the energy meter will switch to Modbus address configuration mode (you will see the screen below).
During this time, the WM3-6 responds to the 149 address via the ModBus. The device remains in configuration mode until the ModBus address is modified or when 3 minutes pass or with a long press of 1 second to 3 seconds. The purpose of the procedure is to modify Modbus address in case if you want to connect more devices with the same address to the RS485 network.
3.5 Limits
WM3-6 has a built-in limit function which can control the bistable relay using IR communication. The user can set one or two logically combined limits. 1 The following logic operations can be selected:

3.6 Freeze counters
3.6.1 Meaning
Since WM3-6 energy meter does not support internaly synchronised real-time clock (RTC) for the purpose of simultaneous capture of measurements, the freeze function is implemented. Use is enabled only when the meter is on. Freeze function enables using WM3x6 smart meters for billing or sub-billing purposes and to compare sub-metering data with main energy meter. Reading several hundred serially connected counters can last more than 10 minutes. That is why WM3x6 supports command Freeze counters. Its purpose is to freeze data simultaneously on all devices in the network. The freeze function operation is also performed in case of device power supply failure or device reset.
3.6.2 Set up
To perform the freeze function, the energy meters should be connected to the serial communication RS485 and belonging software which use Modbus registers. The energy meter WM3x6 enables several ways to activate freeze function:
Freeze status register, time to freeze register, auto freeze interval register.
3.6.3 Time to freeze register (41902)
The purpose of the time to freeze register is to freeze all energy meters simultaneously. Set the number of time to freeze register (41902), the value of appropriate time (in seconds) before the time of the freeze and time of the freeze. After an expired time, the freeze command is executed automatically. Due to unreliability in communication, it is recommended that the desired time is sent more than ones, to ensure that freeze is simultaneous on all instruments. The desired time need to be sent in the interval of one minute. For example, if you want that freeze function is executed at 10 am, run the command seven times, starting 7 s before 10 am and repeat it with a one second interval (see the picture below).
All instruments that received one of the commands will freeze at the same time. This is the advantage
of the described register, so it is recommended to use it. It is also possible to individually enter the appropriate time in register 41902 of each instrument.
3.6.4 Auto freeze interval register (41901)
The purpose of the auto freeze interval register is to freeze energy meters in the same time interval, for example, every day. Set the certain auto freeze interval (in minutes). Maximum allowed value is 65535 minutes. Periodic synchronization is activated automatically after the entered interval. If the interval is set to 0, the auto freeze interval function is turned off. The disadvantage of this register is that the time is not appropriate if the meters reset or in case of another failure.
FIRST STEPS
30
User’s Manual
3.6.5 Status register of freeze (41905)
The purpose of the status register is to test the reliability of RS485 communication. Enter the broadcast command of different identification codes between 1 to FFFD in the freeze status register (41905). Repeatedly send a different identification code to the freeze status register (41905) in order to increase the reliability of receiving commands. The reliability of reading different numbers of identification code enables analysis of communication reliability. In the case of 100% reliability of communication, all instruments have the value of the first sent identification code, when reading the status register. After the instrument receives the identification code, it ignores all entries in the status register in the interval of one minute. Send as many different identification codes in a short time interval. For example, send the different identification codes ten times within one second. Use numbers from 1 to FFFD (1 -
65533). For example, first use value 1, then D, AAA and at the end FFFD (see picture below). Please note that you never know if all the meters will freeze, so send as many commands as possible within one minute.
PLEASE NOTE
Please do not use the values 0000, FFFF or FFFE. The 0000 is reserved to start the meter when connected to the power supply. Freeze function is performed. The FFFF is reserved to trigger freezing function automatically (same as time to freeze register 41902). The FFFE is reserved for the auto interval freeze.
Send the command for reading the register, so you can see which identification code has been accepted
by the individual instrument. The server calculates time from a freeze of the device.
3.6.6 Access and interpretation of data
After the execution of the freeze command, the counters are stored into registers 41906 to 41938, which can be read by the master. Register 41906 displays frozen tariff counter and registers 41907 to 41938 display frozen energy counters (1 - 16). The data we read on all devices can this way be compared. Encoded information should be read with Modbus table (see Appendix A). In addition, the time since the last freeze can be checked with time from freeze register (41903, 41904). The purpose of these register is to control if displayed measurements are relevant. The register contains time (in seconds) from the last freeze counters execution.

7.1 APPENDIX A: MODBUS communication protocol
Modbus protocol enables operation of device on Modbus networks. For WM3-6\WM3M6 with serial communication the Modbus protocol enables multi drop communication via RS485 communication. Modbus protocol is a widely supported open interconnect originally designed by Modicon. The memory reference for input and holding registers is 30000 and 40000 respectively. Communication operates on a master-slave basis where only one device (the master) can initiate transactions called ‘Requests’. The other devices (slaves) respond by supplying the requested data to the master. This is called the ‘Request - Response Cycle’. The master could send the MODBUS request to the slaves in two modes:
- Unicast mode, where the master sends the request to an individual slave. It returns a replay to the master after the request is
received and processed. A MODBUS transaction consists of two messages. Each slave should have an unique address.
- Broadcast mode, where the master sends a request to all slaves and an answer is never followed. All devices should accept the
broadcast request function. The Modbus address 0 is reserved to identify the broadcast request.
Master to Slave Request
Slave to Master Response
Request
This Master to Slave transaction takes the form:
Device address: master addressing a slave (Address 0 is used for the broadcast address, which all slave devices recognize.) Function code e.g. 03 asks the slave to read its registers and respond with their contents. Data bytes: tells the slave which register to start at and how many registers to read.
Response
This Slave to Master transaction takes the form:
Device address: to let the master know which slave is responding. Function code: this is an echo of the request function code. Data bytes: contains the data collected from the slave.

7.2 APPENDIX B: M-BUS
The M-BUS interface fully complies with M-BUS European standard EN13757-2. The entire communication is ensured with 8 Data Bits, Even Parity, 1 Stop Bit and a Baud Rate from 300 to 9600 Bauds.
Communication settings
Default communication settings are: 2400, 8, E, 1 primary address 0 and secondary address is set to serial number of device.
Initialize M-Bus (SNK_NKE)
This Short Telegram initializes the M-BUS WM3-6. The M-BUS WM3-6 confirms correct receipt by Single Character Acknowledgement (ACK = E5). If the telegram was not correctly received the WM3-6 will not send an acknowledgement.
Select M-BUS WM3-6 Using Secondary Address (SND_UD)
This Telegram enables to select M-BUS WM3-6. The M-BUS WM3-6 confirms the correct receipt by ACK. If the telegram has not been correctly received the M-BUS WM3-6 will not send an Acknowledgement. After issue of the Single Character Acknowledgement the M-BUS WM3-6 is ready to transmit the entire Read-out Data within 3 seconds from receiving the Telegram „Transmit Read-out Data“. At the end of 3 seconds the M-BUS WM3-6 will switch back to normal mode.
Transmit Read-out Data via Primary/Secondary Address (REQ_UD2)
This Short Telegram enables to select the M-BUS WM3-6 and to command it to transmit the Read-out Data parameterized. The M-BUS WM3­6 confirms correct receipt by transmitting of the Read-out Data. If the Short Telegram has not been received correctly; no Data will be transmitted by the M-BUS WM3-6. The Read-out Data are sent within 35 ms – 75 ms from receipt of the Short Telegram by the M-BUS Meter (fom more infomations see section M-Bus telegrams).
Set Baud Rate via Primary/Secondary Address (SND_UD)
This telegram enables to set the desired Baud Rate. The M-BUS WM3-6 confirms the correct receipt by ACK. If the telegram was not received correctly the M-BUS WM3-6 does not send an Acknowledgement. The (ACK) is sent by the M-BUS WM3-6 in the Old Baud Rate. As soon as ACK is transmitted the M-BUS Meter switches to the baud rate newly parameterized. If the WM3-6 now does not receive a new Telegram under the new baud rate within a period of 30 seconds – 40 seconds, it automatically switches back to the old baud rate. This is apt to prevent that a faulty setting of the baud rate may interrupt communication.
Set Primary Address via Primary/Secondary Address (SND_UD)
This Telegram enables to set a new Primary Address. The M-BUS WM3-6 confirms the correct receipt by ACK. If the telegram has not been correctly received the M-BUS WM3-6 will not send an Acknowledgement.
Set Secondary Address via Primary/Secondary Address (SND_UD)
This Telegram enables to set a new Secondary Address. The M-BUS WM3-6 confirms the correct receipt by ACK. If the telegram has not been correctly received the M-BUS WM3-6 will not send an Acknowledgement. Secondary Address (UD) consists of: Identification Number: 00000000 – 99999999 8-digit Secondary Address number Manufacturer’s Code: 73 26 2 Byte Company Constant (Iskra = “73 26”) Version Number: 01 – FF 1 Byte Medium: 02 1 Byte Constant Electricit
Reset, Restart M-BUS MC350 via Primary/Secondary Address (SND_UD)
This Telegram reset/restarts M-BUS MC350. The M-BUS WM3-6 confirms correct receipt by ACK. If the telegram was not correctly received the M-BUS WM3-6 will not send an acknowledgement.
