Communication details of diffused silicon pressure transmitter
RS485 MODBUS RTU Protocol Pressure transducer
The meter communication protocol complies with the MODBUS-RTU
communication protocol, 1 start bit, 8 data bits and 1 stop bit.
The following instructions define the meter parameters: the meter
address is set to 1, the communication baud rate 9600, invalid
check, decimal point 1, unit MPa, meter display value 500.0MPa.
Instruction in the read command, write the address and the data of
demand are high byte in front the low byte in the back; CRC check
the low byte in the front, high byte in the back.
