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.

Foreword
EL3692 11Version: 3.1
1.4.2 Version identification of EL terminals
The serial number/ data code 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 serial number 12 06 3A 02:
12 - production week 12
06 - production year 2006
3A - firmware version 3A
02 - hardware version 02

1.4.3 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.2: 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.
Following information is possible, positions 1 to 4 are always present, the other according to need of
production:

Accordingly as DMC:
Fig.3: Example DMC 1P072222SBTNk4p562d71KEL1809 Q1 51S678294
BTN
An important component of the BIC is the Beckhoff Traceability Number (BTN, position 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.
NOTICE
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
without prior notice. No claims for changes can be made from the information, illustrations and descriptions
in this information.

1.4.4 Electronic access to the BIC (eBIC)
Electronic BIC (eBIC)
The Beckhoff Identification Code (BIC) is applied to the outside of Beckhoff products in a visible place. If
possible, it should also be electronically readable.
Decisive for the electronic readout is the interface via which the product can be electronically addressed.
K-bus devices (IP20, IP67)
Currently, no electronic storage and readout is planned for these devices.
EtherCAT devices (IP20, IP67)
All Beckhoff EtherCAT devices have a so-called ESI-EEPROM, which contains the EtherCAT identity with
the revision number. Stored in it is the EtherCAT slave information, also colloquially known as ESI/XML
configuration file for the EtherCAT master. See the corresponding chapter in the EtherCAT system manual
(Link) for the relationships.
The eBIC is also stored in the ESI‑EEPROM. The eBIC was introduced into the Beckhoff I/O production
(terminals, boxmodules) from 2020; widespread implementation is expected in 2021.
The user can electronically access the eBIC (if existent) as follows:
• With all EtherCAT devices, the EtherCAT master (TwinCAT) can read the eBIC from the ESI‑EEPROM
◦ From TwinCAT 3.1 build 4024.11, the eBIC can be displayed in the online view.
◦ To do this,
check the checkbox "Show Beckhoff Identification Code (BIC)" under
EtherCAT→AdvancedSettings→Diagnostics:
◦ The BTN and its contents are then displayed:
◦ Note: as can be seen in the illustration, the production data HW version, FW version and
production date, which have been programmed since 2012, can also be displayed with "Show
Production Info".
◦ Access from the PLC: From TwinCAT 3.1. build 4024.24 the functions FB_EcReadBIC and
FB_EcReadBTN are available in the Tc2_EtherCAT Library from v3.3.19.0 for reading into the
PLC..
• In the case of EtherCAT devices with CoE directory, the object 0x10E2:01 can additionally by used to
display the device's own eBIC; the PLC can also simply access the information here:

Foreword
EL3692 15Version: 3.1
◦ The device must be in PREOP/SAFEOP/OP for access:
◦ The object 0x10E2 will be introduced into stock products in the course of a necessary firmware
revision.
◦ From TwinCAT 3.1. build 4024.24 the functions FB_EcCoEReadBIC and FB_EcCoEReadBTN are
available in the Tc2_EtherCAT Library from v3.3.19.0 for reading into the PLC.
• For processing the BIC/BTN data in the PLC, the following auxiliary functions are available in
Tc2_Utilities from TwinCAT 3.1 build 4024.24 onwards
◦ F_SplitBIC: The function splits the Beckhoff Identification Code (BIC) sBICValue into its
components based on known identifiers and returns the recognized partial strings in a structure
ST_SplitBIC as return value.
◦ BIC_TO_BTN: The function extracts the BTN from the BIC and returns it as a value.
• Note: in the case of electronic further processing, the BTN is to be handled as a string(8); the identifier
"SBTN" is not part of the BTN.
• Technical background
The new BIC information is additionally written as a category in the ESI‑EEPROM during the device
production. The structure of the ESI content is largely dictated by the ETG specifications, therefore the
additional vendor-specific content is stored with the help of a category according to ETG.2010. ID03
indicates to all EtherCAT masters that they must not overwrite these data in case of an update or
restore the data after an ESI update.
The structure follows the content of the BIC, see there. This results in a memory requirement of
approx. 50..200bytes in the EEPROM.
• Special cases
◦ If multiple, hierarchically arranged ESCs are installed in a device, only the top-level ESC carries
the eBIC Information.
◦ If multiple, non-hierarchically arranged ESCs are installed in a device, all ESCs carry the eBIC
Information.
◦ If the device consists of several sub-devices with their own identity, but only the top-level device is
accessible via EtherCAT, the eBIC of the top-level device is located in the CoE object directory
0x10E2:01 and the eBICs of the sub-devices follow in 0x10E2:nn.
PROFIBUS, PROFINET, DeviceNet devices etc.
Currently, no electronic storage and readout is planned for these devices.

2.1 Introduction
Fig.4: EL3692
2 channel resistance measurement terminal
The EL3692 analog input terminal allows direct resistance measurement in 9 measuring ranges from 0..100
MΩ to 0..10 mΩ on 2 channels.
The circuitry of the EtherCAT Terminal enables measurement in 2- and 4-wire versions. The EL3692 offers
measuring range selection, either automatic or through the controller. It is possible to determine the
connected resistance with an update rate up to 100 Hz.
Due to the galvanic isolation of 1500 V between the field side and the E-bus, in single-channel mode
measurements can be carried out at live points (within the permissible range). The EtherCAT Terminal
indicates its state through LEDs. Malfunctions such as broken wires are indicated by error LEDs.
As further variants the EL3692-0020 with individual factory calibration certificate and the EL3692-0030 with
external calibration certificate are available.
Please read the notes on the calibration certificate [}20] and identification features [}20] of these
terminals.

2.2 Technology
The EL3692 resistance measuring terminal can measure resistances between milliohm (mΩ) and megohm
(MΩ). 2- and 4-wire measurements are supported. The terminal is fully configurable via the Bus Coupler or
the control system. Different output formats may be selected or own scaling activated.
Measuring principle of the terminal
The terminal actively applies a current to the test specimen. This current simultaneously flows through
internal reference resistances. The actual resistance is determined from the proportion of the measured
voltages. The terminal measures ratiometrically, i.e. fluctuations in the supply voltage and/or the measuring
current have no influence on the accuracy.
Fig.5: Principle of operation
The figure illustrates the following relationship between the known resistance Rref and the unknown
resistance Rx:
Rx / Rref = Ux / Uref
Rx = Rref * Ux / Uref
The two channels of the EL3692 are measured alternately. To compensate capacitive processes the
conversion time depends on the measuring range: the larger measuring range the longer the conversion. To
measure a resistance at short intervals, the EL3692 should be used in single-channel mode. For measuring
inductive/capacitive loads it should be noted that transition processes influence the result. A delay time can
be specified in the channel settings in the CoE. The measurement and updating of the process data will only
take place once this delay time (in [ms]) has elapsed (CoE 0x80n0:05 and :31 [}165]). This delay time is
particularly significant in Autorange mode: If it is too small, the measuring range may not change in
Autorange mode because the respective measuring range limits are not reached. The automatic control in
the EL3692 will try to optimize the waiting times, although manual adaptation may still be required.
The measuring frequency is determined from the filter setting for each channel. The lower the filter setting,
the more measurements are carried out and averaged, and the more reliable is therefore the measurement.
The 9 measuring ranges each cover one decade. They each measure from 0 Ohm to 110% of full scale with
their typical measuring current, see table. The measuring ranges of the two channels can be used
independently of each other.
Although all measuring ranges theoretically measure down to 0 Ohm, the relatively large measuring error
and the 2/4-wire connection technology must be taken into account with such small resistances. Apart from
that, it will hardly be possible to achieve a "correct" zero measured value, because not even a connected
(short) wire bridge has a resistance of 0 Ω.

In AutoRange mode, the measuring range used is determined by the terminal itself. For AutoRange
operation, each measuring range can measure up to 110% above the respective measuring range end
value. In this range, the measuring range is then switched to the next higher measuring range. Accordingly,
below 10% of the measuring range, the changeover to the next smaller measuring range takes place. This
method results in the following naming of the measuring ranges e.g. as "10..100 Ω", with 100Ω as measuring
range end value and 10 Ω as lower threshold for the measuring range switchover.
In the manual mode, the measuring range is specified by the user via process data or CoE, in this case
0..110% of the respective measuring range can be measured.
The respective resistance is measured with 24 bit resolution (incl. sign). The measured value transmission
takes place as 32 bit process date, in float (fixed point) or integer representation. Since no negative
resistances can occur, the sign bit is used for the representation up to 110%

2.4 Note on Beckhoff calibration certificates
Basically every Beckhoff analogue device (input or output) will be justified i.e. will be calibrated during
production. This procedure won’t be documented unique. This documentation as a calibration certificate is
only provided for devices that are expressly delivered with a certificate.
The calibration certificate (or German: “Kalibrierschein”) entitles the residual error after compensation/
adjustment to the used standard (reference device). The calibration certificate (as a PDF document) is to be
assigned to the device via a unique number. It is therefore not a statement about a device class such as e.g.
an approval, but always only applies to a single, named device. It is available for download.
The calibration certificate documents the measurement accuracy at the time the certificate was issued and
contains, among other things, information on the ambient conditions and the reference instrument used. It
does not contain statement about the behavior or the change of the measuring accuracy in the future. A
calibration certificate acts as a backtracking view to the previous time of usage. By reiterated certification
procedures over years (without justification) it allows making conclusions about its ageing behavior, so called
calibrate history.
Performance levels of the calibration certificates
Different "qualities" of a calibration certificate are common:
• Beckhoff calibration certificates
Such IP20 terminals can be usually identified by the product suffix -0020. The certificate is issued in
Beckhoff production as PDF.
The terminals can be obtained from Beckhoff and recalibrated by the Beckhoff service department.
• ISO17025 calibration certificates
Such IP20 terminals can be usually identified by the product suffix -0030. The certificate is issued by a
service provider on behalf of Beckhoff as part of Beckhoff production and delivered by Beckhoff as a
PDF.
The terminals can be obtained from Beckhoff and recalibrated by the Beckhoff service department.
• DAkkS calibration certificates (German: "Deutsche Akkreditierungsstelle GmbH")
Such IP20 terminals can be usually identified by the product suffix -0030. The certificate is issued by a
accredited service provider on behalf of Beckhoff as a part of Beckhoff production and delivered by
Beckhoff as a PDF.
The terminals can be obtained from Beckhoff and recalibrated by the Beckhoff service department.
