ABB Drive Firmware Version Decoding Technical Note

This technical note explains how to decode firmware version values transmitted from ABB drives to a PLC via fieldbus, converting non-intuitive hexadecimal data into a clear decimal format as displayed on the drive keypad or in Drive Composer software. It covers both 16-bit and 32-bit transmission formats, detailing the breakdown of byte segments for major, minor, patch, and variant codes using examples from ACS880, ACS580, and other drive models.
