Sensor matching digital transmitter, RS232, RS485 output

Characteristic:

Stable and reliable performance measurement accuracy and intuitive, compact size, the use of flexible,Universal transmitter, suitable for all kinds of industrial equipment with PC monitoring software, equipped with complete detailed communication protocol, zero calibration, display calibration function.

Digital sensor communication protocol

1, protocol type: RTU MODBUS

Please refer to the specific RTU MODBUS protocol

MODSCAN software can be used to test

2, communication mode: RTU - RS485 MODBUS half duplex, master-slave mode

3,Serial data format: the use of 11 bit data format:

• 1 bit start bit + 8 bit data bit + 1 bit parity check (EVEN) + 1 bit stop bit (MODBUS default mode)
• Baud rate: 19200 baud

Message frame format of communication between sensor and host computer:

The message frame format of the sensor and the host computer is shown in table 1-3

(in which the current address range of the sensor: 0-99; sensor to receive and send data to a floating point conversion of four bytes, the company provides the host computer calibration procedures
