1.4 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 Type Version Revision

EL3314-0000-0016 EL terminal

(12 mm, non-

pluggable connection

level)

3314 (4-channel thermocouple

terminal)

0000 (basic type) 0016

ES3602-0010-0017 ES terminal

(12 mm, pluggable

connection level)

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.

Foreword

EL72x1-901x 11Version: 1.9

• 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

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.

1.4.1 Beckhoff Identification Code (BIC)

The Beckhoff Identification Code (BIC) is increasingly being applied to Beckhoff products to uniquely identify

the product. The BIC is represented as a Data Matrix Code (DMC, code scheme ECC200), the content is

based on the ANSI standard MH10.8.2-2016.

Fig.9: BIC as data matrix code (DMC, code scheme ECC200)

The BIC will be introduced step by step across all product groups.

Depending on the product, it can be found in the following places:

• on the packaging unit

• directly on the product (if space suffices)

• on the packaging unit and the product

The BIC is machine-readable and contains information that can also be used by the customer for handling

and product management.

Each piece of information can be uniquely identified using the so-called data identifier

(ANSIMH10.8.2-2016). The data identifier is followed by a character string. Both together have a maximum

length according to the table below. If the information is shorter, spaces are added to it. The data under

positions 1 to 4 are always available.

The following information is contained:

...

Further types of information and data identifiers are used by Beckhoff and serve internal processes.

Structure of the BIC

Example of composite information from item 1 to 4 and 6. The data identifiers are marked in red for better

display:

BTN

An important component of the BIC is the Beckhoff Traceability Number (BTN, item no.2). The BTN is a

unique serial number consisting of eight characters that will replace all other serial number systems at

Beckhoff in the long term (e.g. batch designations on IO components, previous serial number range for

safety products, etc.). The BTN will also be introduced step by step, so it may happen that the BTN is not yet

coded in the BIC.

NOTE

This information has been carefully prepared. However, the procedure described is constantly being further

developed. We reserve the right to revise and change procedures and documentation at any time and with-

out prior notice. No claims for changes can be made from the information, illustrations and descriptions in

this information.

), EL7211-901x (50V

DC

, 4.5A

) and

EL7221-901x (50V

DC

, 7…8A

) with integrated absolute value interface, offer high servo performance in a

very compact design. The EL72x1-901x were designed for the motor types of the AM81xx series from

Beckhoff Automation.

The fast control technology, based on field-orientated current and PI speed control, supports fast and highly

dynamic positioning tasks. The monitoring of numerous parameters, such as overvoltage and undervoltage,

overcurrent, terminal temperature or motor load via the calculation of a I²T model, offers maximum

operational reliability.

Product overview

EL72x1-901x 19Version: 1.9

EtherCAT, as a high-performance system communication, and CAN-over-EtherCAT (CoE), as the

application layer, enable ideal interfacing with PC-based control technology.

The latest power semiconductors guarantee minimum power loss and enable feedback into the DC link when

braking.

The LEDs indicate status, warning and error messages as well as possibly active limitations.

With the One Cable Technology (OCT) the encoder cable is omitted by transmitting the signals of the

encoder digitally via the existing motor cable. The option to read the electronic type plates of suitable motors

from the AM81xx series enables a plug-and-play solution for maximum convenience during commissioning.

The EL72x1-901x provides an STO input with which the motor connected to the terminal can be switched

torque-free. This STO input is connected to a safe output of an EL2904.

Performance Level d, Category 3 according to DIN EN ISO 13849-1:2015 is attained for the SFO safety

function of the EL72x1-901x together with an EL2904.

Recommended TwinCAT version

In order to be able to utilize the full power of the EL72x1-901x, we recommend using the

EL72x1-901x with TwinCAT 2.11 R3 or higher!

Mandatory hardware

The EL72x1-901x must be operated with a real-time capable computer and distributed clocks!

Approved motors

The EL72x1-901x may be operated only with the following Beckhoff motors.

- AM8111-xF1x, AM8112-xF1x, AM8113-xF1x, AM8121-xF1x, AM8122-xF1x, AM8131-xF1x,

AM8132-xJ1x, AM8133-xJ1x, AM8141-xJ1x

- AM8111-xF2x, AM8112-xF2x, AM8113-xF2x, AM8121-xF2x, AM8122-xF2x, AM8131-xF2x,

AM8132-xJ2x, AM8133-xJ2x, AM8141-xJ2x

Operation of the EL7221-901x with fan cartridge ZB8610

Due to the increased thermal load, the EL7221-091x must only be operated in conjunction with the

fan cartridge ZB8610 in order to avoid malfunctions.
