That calculator is helpful in that it provides a general idea of what might receive. Calculate the CRC32 checksum of any file, regardless of its format, in order to use this alphanumerical value for file comparison. Until now, I have succeded to calculate CRC-16 and CRC-CCITT (0xFFFF) but not CRC-Modbus. Modbus Cyclical Redundancy Checksum (CRC) Calculator : Programmers who write device drivers or other routines to communicate with Modbus RTU serial devices can use the routine below to calculate the CRC checksum for any Modbus command.
