General notes on marking
Designation
A Beckhoff EtherCAT device has a 14-digit designation, made up of
- family key
- type
- version
- revision
Example | Family | Type | Version | Revision |
|---|---|---|---|---|
EL3314-0000-0016 | EL terminal | 3314 (4-channel thermocouple terminal) | 0000 (basic type) | 0016 |
ES3602-0010-0017 | ES terminal | 3602 (2-channel voltage measurement) | 0010 (high-precision version) | 0017 |
CU2008-0000-0000 | CU device | 2008 (8-port fast ethernet switch) | 0000 (basic type) | 0000 |
Notes
- The elements mentioned above result in the technical designation. EL3314-0000-0016 is used in the example below.
- EL3314-0000 is the order identifier, in the case of “-0000” usually abbreviated to EL3314. “-0016” is the EtherCAT revision.
- The order identifier is made up of
- family key (EL, EP, CU, ES, KL, CX, etc.)
- type (3314)
- version (-0000) - The revision -0016 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 web site.
From 2014/01 the revision is shown on the outside of the IP20 terminals, see Fig. “EL5021 EL terminal, standard IP20 IO device with batch number and revision ID (since 2014/01)”. - The type, version and revision are read as decimal numbers, even if they are technically saved in hexadecimal.
