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”.

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.

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.

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.
