online parser: crc presentation

[a.pythe]

@Mikhail, shure.

Testing example byte set, 6 (six) bytes length: 01 02 03 04 05 06

Whatever the set is, it’s CRC-16/MODBUS value is DDBA(hex) 56762(dec)

So, according to the Modbus specification the set with CRC bytes added is 01 02 03 04 05 06 BA DD

When fed to the Rapid SCADA Modbus Parser this set is parsed as a good data package, but it’s CRC shown at the bottom of the page is presented in reverse byte order as BADD(hex) 47837(dec) integer.

Make shure 47837 is not equal to 56762.

Thank you for your attention to this matter! 🙂
