Three, module RS-485 communication instructions
The 1. module uses standard MODBUS-RTU protocol to facilitate the connection of PLC and configuration software.
2. the bits of each byte in the protocol: 1 start bits, 8 data bits, no parity bits, and 1 bit stop bits. Using CRC-16 check.
3. function code 04H: read hold register, read measurement data
Data start address range: 0100H to 010FH
Data Description: read 32 bit data, low word in front, high word in back.
Temperature data format description: one temperature data for 4 bytes, a total of 32bit (here 16 high, 0 has been), the actual temperature = reading measurement value /65536* range, the unit is: temperature
