Foreword
2.4 Version identification of EtherCAT devices
Designation
A Beckhoff EtherCAT device has a 14­digit designation, made up of
• family key
• type
• version
• revision
Example Family Type Version Revision
EL3314­0000­0016 EL terminal
(12 mm, non­
pluggable
connection level)
3314 (4­channel
thermocouple
terminal) 0000 (basic type) 0016
CU2008­0000­000
0 CU device 2008 (8­port fast
ethernet switch) 0000 (basic type) 0000
ES3602­0010­0017 ES terminal
(12 mm, pluggable
connection level)
3602 (2­channel
voltage
measurement) 0010 (high­
precision version) 0017
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.
• The type, version and revision are read as decimal numbers, even if they are technically saved in
hexadecimal.
Identification number
Beckhoff EtherCAT devices from the different lines have different kinds of identification numbers:
Production lot/batch number/serial number/date code/D number
Serial number is the name generally given to the 8­digit number that is printed on the device or attached to it
on a sticker. This serial number indicates the as­built status on delivery and thus ambiguously marks a whole
production lot.
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.: 12063A02: 12 ­ production week 12 06 ­ production year 2006 3A ­ firmware version
3A 02 ­ hardware version 02
