9.6.3 CRC checking
In RTU mode, messages include an error-checking field that is based on a CRC method. The CRC field
checks the contents of the entire message. The CRC field 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, and compares the calculated value to
the actual value received in the CRC field. If the two values are not equal, an error results.
