Version identification of EtherCAT devices

Designation

A Beckhoff EtherCAT device has a 14-digit designation, made up of

• family key

• type

• version

• revision

Example Family

EL3314-0000-0016 EL terminal

(12 mm, nonpluggable connection level)

ES3602-0010-0017 ES terminal

(12 mm, pluggable connection level)

CU2008-0000-0000 CU device

Type

3314 (4-channel thermocouple terminal)

3602 (2-channel voltage measurement)

Version Revision

0000 (basic type) 0016

0010 (highprecision version)

0017

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.

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

The serial number for Beckhoff IO devices is usually the 8-digit number printed on the device or on a sticker.

The serial number indicates the configuration in delivery state and therefore refers to a whole production batch, without distinguishing the individual modules of a batch.

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

12 Version: 4.2

EL33xx-00x0

Foreword

Example with

Ser. no.: 12063A02:    12 - production week 12 06 - production year 2006 3A - firmware version 3A 02 hardware version 02

Exceptions can occur in the IP67 area , where the following syntax can be used (see respective device documentation):

Syntax: D ww yy x y z u

D - prefix designation ww - calendar week yy - year x - firmware version of the bus PCB y - hardware version of the bus PCB z - firmware version of the I/O PCB u - hardware version of the I/O PCB

Example: D.22081501 calendar week 22 of the year 2008 firmware version of bus PCB: 1 hardware version of bus PCB: 5 firmware version of I/O PCB: 0 (no firmware necessary for this PCB) hardware version of I/O

PCB: 1

Unique serial number/ID, ID number

In addition, in some series each individual module has its own unique serial number.
