WebFrom Wikipedia, the free encyclopedia. A cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. WebThe C language code snippet below shows how to compute the Modbus message CRC using bit-wise shift and exclusive OR operations. The CRC is computed using every byte in the message frame except for the last two bytes …
