Notes
• the elements named above make up the technical designation
• The order designation, conversely, is made up of
- family key (EL, EP, CU, ES, KL, CX, etc.)
- type
- version
• The revision shows the technical progress, such as the extension of features with regard to the
EtherCAT communication, and is managed by Beckhoff.
In principle, a device with a higher revision can replace a device with a lower revision, unless specified
otherwise, e.g. in the documentation.
Associated and synonymous with each revision there is usually a description (ESI, EtherCAT Slave
Information) in the form of an XML file, which is available for download from the Beckhoff website.
The revision has been applied to the IP20 terminals on the outside since 2014/01, see fig. 1.
