WebMar 15, 2024 · We now have what we need to compute CRC-16/MODBUS, which has both a non-zero Init value ( 0xffff) and RefIn and RefOut as true. We start with the message with the bits in each byte reflected and the first 16 bits inverted. That is 7f f7 03 c0 00 80. Divide by 0x18005 and you get the remainder 0xb393. 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.
