Serial Communication

The device has optical isolated MODBUS RTU communication protocal. All the 

measured parameters can be transferred to the computer. Transformer ratio and 

communication parameters can be set. Saved demand and energy values can be 

resetted.

Parameter Settings

Address Parameter : Between 001-247.

Baud Rate parameter : Can be chosen 2400, 4800, 9600, 19200 and 38400 bps.

Parity parameter : Can be chosen “no”, “odd” and “EUEn”.

is entered but is not activated yet. For activating please follow the below steps)

Press ESC button one by one, until “SAU E SEt yES” is displayed. 

Press SET button when “SAU E SEt yES” is displayed. If you press 

ESC button or choose “no” option instead of “yES” option by using 

UP/DOWN buttons, new option will be cancelled, previous option will 

be activated.

MODBUS RTU PROTOCOL

Standart MODBUS RTU message is shown below. 

The T times corresponds to a time in which data must not be exchanged on the 

communication bus to allow the connected devices to recognize the end of one mes-

sage and the beginning of another. This time must be at least 3.5 characters at the 

selected baud rate. Adress range (1-247)  is address of the connected device. The 

CRC is a error check method by using MODBUS RTU protocol and consists of 2 

bytes.

Available Modbus Function

Read Hold (03) function is used for reading the measured parameter and setting 

values. Device will sent error message if the device tries to read addresses which 

are not in the register table.

For example to read phase 1 voltage below message can be sent;

01 03 00 00 00 02 XX XX

  01 Device address

  03 Function

  00 MSB address

  00 LSB address

  00 Register number MSB

  02 Register number LSB

  XX CRC MSB

  XX CRC LSB

Preset Single Register (06) function is used for writting energy values, erasing ener-

gy counter or reseting the min., max. demand values. Current transformer ratio can 

be set between 1-2000, voltage transformer ratio can be set between 1-400000.

For example setting CT ratio as 100;

01 06 80 02 00 64 XX XX

  01 Device address

  06 Function

  80 MSB address

  02 LSB address

  00 Data MSB

  64 Data LSB

  XX CRC MSB

  XX CRC LSB

Preset Multiple register (10H) function is used for changing more than one register 

value. 

For example setting ratio as 100 and voltage transformer ratio as 20.0.;

01 10 80 00 00 02 04 00 C8 00 64 XX XX girilebilir.

  01 Device Address

  02  Register number LSB

  04  Byte count

  00  Data MSB

  C8  Data LSB

Digital Input

Din (Din=Dijital giriş)16 bit olarak aşağıda gösterildiği gibi gönderilir.

In1 (input 1) if 12-48 V AC / DC is applied to in 1, 0 bit of DIN register is set as “1”. In 

otherwise 0 bit of  DIN register is set as “0”.

In2 

(input 2) if 12-48 V AC / DC is applied to in 2, 1 bit of DIN register is set as “1”. In 

otherwise 0 bit of  DIN register is set as “0”.

Parameters are sent in 32 bit Hexadecimal form. For example 230,0 V voltage 

is sent as 000008FCH. Cosj is divided by 1000. 0.980 Cosj value is sent as 

000003D4H. Energy values are sent as 64bit. 

12345678901234567890 Wh = AB 54 A9 8C EB 1F 0A D2 Wh    

Data Cable : 

- 24 AWG or thicker

- Less than 100 ohm-km impedance

- Nominal characteristic impedance in 100 kHz is 100 ohm.

- Between 2 wires mutual capacitance is less than 60 pF/m

- Between one wire and all the wires which are grounded mutual capacitance is less 

than 120 pF/m.

- Double wire. 

ERROR CODES

Slave device (MPR-53CS) sends error message when receive any missing query. 

Error codes are given below:

01 Invalid Function:

 If any message except given above is used, then 01 error 

messages will be sent.

02 Invalid Register: 

Error 02 will be send when a reading of a register is requested, 

except the registers which mentioned in table.

03 Invalid data:

and nonzero for demand value, then error message 03 will be sent.
