CRC Checking
In RTU mode, messages include an error-checking îš¿eld that is based on a CRC method. The
CRC îš¿eld checks the contents of the entire message. The CRC îš¿eld is two bytes, containing a
16-bit binary value. The CRC value is calculated by the transmitting device, which appends the
CRC to the message. The receiving device recalculates a CRC during receipt of the message,
