1.5 Version identification of EtherCAT devices

Designation

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

• family key

• type

• version

• revision

EL28xx-xxxx8 Version: 2.2

Foreword

Example Family Type Version Revision

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 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.

3602 (2-channel voltage measurement)

0000 (basic type) 0016

0010 (highprecision version)

0017

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

EL28xx-xxxx 9Version: 2.2

Foreword

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.

Foreword

1.6 Non-reactive Bus Terminals

Use of non-reactive Bus or EtherCAT Terminals in safety applications

If a Bus or EtherCAT Terminal is described as non-reactive, this means that the consecutive terminal behaves passively in a safety application (e.g. in the case of the all-pole switch-off of a potential group). In this case the terminals do not represent an active part of the safety controller and do not affect the Safety Integrity Level (SIL) or Performance Level (PL) attained in the safety application.

For details, please refer to chapter 2.17f in the TwinSAFE application manual.

NOTE

Pay attention to the hardware version

Please pay attention to the information about the hardware version and non-reactivity of the respective Bus Terminal in the chapters "Technical Data" or "Firmware Compatibility"! Only terminals with the appropriate hardware version may be used without the attained SIL/PL being affected!

The Bus or EtherCAT Terminals regarded as non-reactive at the time of preparing this document are listed in the following tables together with their respective hardware versions.

Hardware versions

External wiring

The following requirements are to be ensured by the system manufacturer and must be incorporated into the user documentation.

• Protection class IP54 The terminals must be installed in IP54 control cabinets to ensure the necessary protection class IP54.

• Power supply unit The standard terminals must be supplied with 24V by an SELV/PELV power supply unit with an output voltage limit U

• Prevention of feedback Feedback can be prevented through different measures. These are described below. In addition to mandatory requirements there are also optional requirements, of which only one needs to be selected.

EL28xx-xxxx 13Version: 2.2

of 60V in the event of a fault.

max

Foreword

◦ No switching of loads with a separate power supply

Loads that have their own power supply must not be switched by standard terminals, since in this case feedback via the load cannot be ruled out.

Fig.9: Negative example – active load

◦ The control of an STO input of a frequency converter could serve here as a negative example.

Exceptions to the general requirement are allowed only if the manufacturer of the connected load guarantees that feedback to the control input cannot occur. This can be achieved, for example, through adherence to load-specific standards.

◦ Option 1: Ground feedback and all-pole disconnection

The ground connection of the connected load must be fed back to the safely switched ground of the respective output terminal.

EL28xx-xxxx14 Version: 2.2

Foreword

Fig.10: Ground connection of the load: correct (K1) and incorrect (K2)

◦ If either

a) the ground of the load is not fed back to the terminal or b) the ground is not safely switched but connected permanently

then fault exclusions are necessary with regard to a short-circuit with external potential in order to be able to achieve Cat. 4 PLe according to EN ISO 13849-1:2007 or SIL3 according to IEC 61508:2010 (refer here to the overview in the chapter "Effect of options on the safety level").

◦ Option 2: Cable short-circuit fault exclusion

If solution option 1 is not feasible, the ground feedback and all-pole disconnection can be dispensed with if the danger of feedback due to a cable short-circuit can be excluded by other measures. These measures, which can be implemented alternatively, are described in the following sections.

EL28xx-xxxx 15Version: 2.2

Foreword

Fig.11: Short circuit fault exclusion through protected cable laying

◦ a) Possibility 1: Load connection via separate sheathed cables

The non-safely switched potential of the standard terminal may not be conducted together with other potential-conducting cores inside the same sheathed cable. (Fault exclusion, see EN ISO

13849-2:2013, Table D.4)

◦ b) Possibility 2: Wiring only inside the control cabinet

All loads connected to the non-safe standard terminals must be located in the same control cabinet as the terminals. The cables are routed entirely inside the control cabinet. (Fault exclusion,

see EN ISO 13849-2:2013, Table D.4)

◦ c) Possibility 3: Dedicated earth connection per conductor

All conductors connected to the non-safe standard terminals are protected by their own earth connection. (Fault exclusion, see EN ISO 13849-2:2013, Table D.4)

◦ d) Possibility 4: Cable permanently (fixed) installed and protected against external damage

All conductors connected to the non-safe standard terminals are permanently fixed and, e.g. protected against external damage by a cable duct or armored pipe.

• Effect of the options on the safety level In principle, standard terminals in safely switched potential groups are not an active part of the safety controller. Accordingly, the safety level attained is defined only by the higher-level safety controller, i.e. the standard terminals are not included in the calculation! However, the wiring of the standard terminals can lead to limitations in the maximum attainable safety level. Depending on the solution selected for the avoidance of feedback and the safety standard considered (see Option 1 and Option 2), different maximum attainable safety levels result, which are summarized in the following table:

The EtherCAT Terminal contains eight channels, consisting of a signal output and 0V, whose signal states are displayed by LEDs. The power contacts are connected through.

The outputs are fed via the 24V power contact in the EL2828. The conductors can be connected without tools in the case of single-wire conductors using a direct plug-in technique. The maximum total output current of the terminal is 10A.

The HD EtherCAT Terminals (High Density) with increased packing density are equipped with 16 connection points in the housing of a 12-mm terminal block.
