The button will select the display context and buttons will navigate between possible values of this context.

Kilo/Mega (k/M) led will turn on if the displayed value is in kA/kV/MW/MVA/MVAr. TOTAL led will turn on when displaying total values.

Normally, the led indicating the values on display will be on. Other leds will turn off. If total working hours is displayed then only the TOTAL led will turn on.

When displaying voltage, current, THD, power factor, etc.. each display will show the value related to one phase. When total values are displayed, depending on the length of the data to display, all 3 displays may be used.

Display of currents: If the greatest current value to display is larger than 999A then the k/M (kilo/mega) led will turn on, otherwise it will turn off. When the k/M led is off, if the

greatest current value is below 100A then currents will be displayed with 0.1A precision, otherwise they will be displayed with 1A precision. When the k/M led is on, if the greatest current value is below 10kA then currents will be displayed with 0.01kA precision, otherwise they will be displayed with 0.1kA precision.

Display of voltages: If the greatest voltage value to display is larger than 999V then the k/M (kilo/mega) led will turn on, otherwise it will turn off. When the k/M led is off, voltages

will be displayed with 1V precision. When the k/M led is on, if the greatest voltage value is below 10kV then voltages will be displayed with 0.01kV precision, between 10kV and

99.9kV they will be displayed 0.1kV precision and above 100kV they will be displayed with 1kV precision.

Display of kW, kVA, kVAr: Depending on the values, they will be displayed with 0.1k or 1k or 0.01M precision.

The unit offers serial data communication port allowing it to be integrated in automation systems.

The serial port is of RS-485 MODBUS-RTU standard. It is fully isolated from power supply and measurement terminals for failure-free operation under harsh industrial conditions.

The MODBUS properties of the unit are:

-Data transfer mode: RTU

-Serial data: 1200-115200 bps adjustable, 8 bit data, no parity, 1 bit stop

-Supported functions:

-Function 3 (Read multiple registers)

-Function 6 (Write single register)

-Function 10h (Write multiple registers)

-The answer to an incoming message is sent with a minimum of 4.3ms delay after message reception.

Each register consists of 2 bytes (16 bits). Larger data structures contain multiple registers.

Detailed description about the MODBUS protocol is found in the document “Modicon Modbus Protocol Reference Guide”. This document may be downloaded at:

http://www.modbus.org/specs.php

Data Reading

The function 03 (read multiple registers) will be used for data reading. The MODBUS master will send a query. The answer will be one of the below:

-A response containing the requested data

-An exceptional response indicating a read error. The maximum number of registers read in one message is 123. If more registers are

requested, the unit will send only the first 123 registers. The query message specifies the starting register and quantity of registers to be read. The

CRC calculation

Here is a procedure for generating a CRC:

1) Load a 16–bit register with FFFF hex (all 1’s). Call this the CRC register.

2) Exclusive OR the first 8–bit byte of the message (the function code byte) with the low– order byte of the 16–bit CRC register, putting the result in the CRC register.

3) Shift the CRC register one bit to the right (toward the LSB), zero–filling the MSB. Extract and examine the LSB. The LSB is the least significant bit of the CRC before the shift operation.

4) If the LSB is 1: Exclusive OR the CRC register with the polynomial value A001 hex.

5) Repeat Steps 3 and 4 until 8 shifts have been performed. Thus, a complete 8–bit byte will be processed.

6) Repeat Steps 2 through 5 for the next 8–bit byte of the message. Continue doing this until all bytes have been processed.

7) The final contents of the CRC register is the CRC value.

8) Place the CRC into the message such that the low byte is transmitted first. The algorithm should give the correct CRC for below messages:

01 03 00 20 00 10 45 CC 01 06 00 40 00 10 89 D2

DKM-407 Kullanım Kılavuzu V-1.1

31

Error codes

Only 3 error codes are used: 01: illegal function code 02: illegal address 10: write protection (attempt to write a read_only register)

Data types

Each register consists of 16 bits (2 bytes) If the data type is a byte, only the low byte will contain valid data. High byte is don’t care. For data type longer than 16 bits, consecutive registers are used. The least significant

register comes first.

Commands to the device are given by writing to below addresses. If the value of “3282” is written to the address 16384, then below commands will be
