- family key
- type
- version
The revision indicates the technical progress and is managed by Beckhoff.
In principle, a device with a higher revision can replace a device with a lower revision, unless specified otherwise.
Each revision usually has an associated XML description (ESI, EtherCAT Slave information), which is available for download from the Beckhoff webpage.
Type, version and revision are read as decimal numbers.

Serial number

Beckhoff EtherCAT devices usually have an 8-digit serial number, which is printed on the device or attached to it on a sticker. This serial number indicates the construction condition on delivery.

Syntax of the serial number

Structure of the serial number: KK YY FF HH

KK - week of production (CW, calendar week)
YY - year of production
FF - firmware version
HH - hardware version

Example with ser. no.: 12 06 3A 02:

12 - week of production 12
06 - year of production 2006
3A - firmware version 3A
02 - hardware version 02
