Description

The meter has RS485 remote reading function and the following optional functions (blue backlight, to display power failure, total power, current, voltage, power, power factor, frequency, etc.) and can accurately measure active energy. The energy meter has a large screen LCD screen.

The single-phase two-wire din-rail energy meter also has a pulse output independent of the internal circuit. The port 21 of the meter is connected to the positive pole, and the port 20 is connected to the negative pole. The port 23 is the positive pole of RS485, and the port 24 is the negative pole of RS485. The circuit requires a voltage of 5~27V DC and a maximum current of 27 mA DC.

1.9.4 RS485 Communication Meter Reading Application (Communication Protocol) and Register Address

The meter can remotely record data such as electric energy in the meter through his RS485 interface and transcribe the electric energy data in the meter at close range with the handheld computer through its infrared communication interfac. The encoding format, parity (even parity) and data transmission mode (eight data bits, one stop bit) meet the MODBUS-RTU standard requirements. The communication baud rate can be 1200bps, 2400bps, 4800bps or 9600bps (default). If there is no special requirement, the meter is set according to the default baud rate of 9600bps. The meter address and communication baud rate can be modified by the software we provide.

2Register Type

The meter uses two types of registers, independently addressed.

The first type is the data register, read-only, using command code 0x04 to read.

The second type is the parameter register, which is readable and writable, read using command code 0x03, and set using command code 0x10.

3Data Format

Float type dataThe data read from the meter conforms to the IEEE-754 standard floating-point number, and the data format is a 32-bit 4-byte single-precision floating-point data format
