• Hardware

  • Shenchen Peristaltic Pump

  

  MODBUS-RTU standard communication is used to control the pump, message frame as below：

  Slave address	Function code	Data area	CRC Check (Cyclic Redundancy Check)
  1 Byte	1 Byte	or up to 252 bytes	2 Bytes
  			CRC low CRC high

  CRC check: CRC code is 2 bytes, 16 check codes. Use CRC-16(which used in American binary synchronous system).

  Polynomial: G(X)=X16+X15+X2+1.
