That might be a ready to use instruction in the function library of the PLC.

Depending of what PLC you are using.

Mitsubishi has this function built in, and it's surprisingly called "CRC".

What language are you using for this function ?

There is a CRC spreadsheet calculator to download from Simply Modbus web site

Take a look at the spreadsheet, it will give you a hint how to calculate CRC.
