Peacefair Pzem-004t-D-P 32A/63A/100A Smart Energy Monitor Single Phase Volt AMP Modbus RTU Pin Connector Ttl Power Watt Meter

Product Description

This is type customized on the basis of the original function of PZEM-004T 3.0 version, it use the pin terminal connector on both of the end on the PCB and add the pulse output function, the pulse constant is 1600mp

Input (Application):110/220VAC/100A
Output:RX TX CF GND
Power Supply:5V
Power:22KW max
All other function is as same as the PZEM-004T 3.0 version, please refer it.

1. Communication protocol 
   1. Physical layer protocol

Physical layer use UART to RS485 communication interface
Baud rate is 9600, 8 data bits, 1 stop bit, no parity

1. 1. Application layer protocol

The application layer use the Modbus-RTU protocol to communicate. At present, it only supports function codes such as 0x03 (Read Holding Register), 0x04 (Read Input Register), 0x06 (Write Single Register), 0x41 (Calibration), 0x42 (Reset energy).etc.
0x41 function code is only for internal use (address can be only 0xF8), used for factory calibration and return to factory maintenance occasions, after the function code to increase 16-bit password, the default password is 0x3721
The address range of the slave is 0x01 ~ 0xF7. The address 0x00 is used as the broadcast address, the slave does not need to reply the master. The address 0xF8 is used as the general address, this address can be only used in single-slave environment and can be used for calibration etc.operation.

1. 1.  Read the measurement result

The command format of the master reads the measurement result is(total of 8 bytes):
Slave Address + 0x04 + Register Address High Byte + Register Address Low Byte + Number of Registers High Byte + Number of Registers Low Byte + CRC Check High Byte + CRC Check Low Byte.
The command format of the reply from the slave is divided into two kinds:
Correct Reply: Slave Address + 0x04 + Number of Bytes + Register 1 Data High Byte + Register 1 Data Low Byte + ... + CRC Check High Byte + CRC Check Low Byte
Error Reply: Slave address + 0x84 + Abnormal code + CRC check high byte + CRC check low byte
Abnormal code analyzed as following (the same below)

1. 0x01,Illegal function
2. 0x02,Illegal address
3. 0x03,Illegal data
4. 0x04,Slave error

FAQ
