Foreword

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.

Foreword

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.

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 with­out prior notice. No claims for changes can be made from the information, illustrations and descriptions in
this information.

2 Product overview

2.1 EK1300 - Introduction

Product overview

EtherCAT coupler EK1300

The EK1300 coupler integrates EtherCAT Terminals (ELxxxx) in the EtherCAT P network. The upper
EtherCAT P interface is used to connect the coupler to the network, the lower EtherCAT-P-coded M8 socket
is used for optional continuation of the EtherCAT P topology. Since EtherCAT P integrates the power supply
and the communication on a single line, an additional power supply for the coupler via the terminal points is
no longer required. Depending on the application, the system and sensor supply US or the peripheral voltage
for actuators UP can be bridged to the power contacts. In addition to the Run LED and the link and activity
status, status LEDs indicate the state of the US and UP voltages, as well as overload and short-circuit events.

2.2 EtherCATP

EtherCATP combines communication and power in a single 4-wire standard Ethernet cable. The 24VDC
supply of the EtherCATP slaves and the connected sensors and actors is integrated within this bus system:
US (system- and Sensor supply) and UP (peripheral voltage for actors) are electrical isolated with 3A current
available for the connected components. All the benefits of EtherCAT, such as freedom in topology design,
high speed, optimum bandwidth utilization, telegram processing on-the-fly, highly precise synchronization,
extensive diagnostics functionality, etc. are all retained while integrating the voltages.

With EtherCATP technology, the currents are coupled directly into the wires of the 100 Mbit line, enabling
the realization of a highly cost-effective and compact connection. In order to rule out the possibility of
incorrect connections to standard EtherCAT slaves and, thus possible defects, a new plug family has been
specially developed for EtherCATP. The plug family covers all applications from the 24 V I/O level up to
drives with 400 V AC or 600 V DC and a current of up to 64 A.

EtherCATP offers extensive savings potential:

• elimination of separate supply cables

• low wiring effort and significant time savings

• sources of error are reduced

EK1300 13Version: 1.1

Product overview

• minimization of installation space for drag-chains and control cabinets

• smaller and tidier cable trays

• smaller sensors and actuators through the elimination of separate supply cables

As is typical with EtherCAT, the user benefits from the wide choice in topology and can combine line, star
and tree architectures with one another in order to achieve the least expensive and best possible system
layouts. Unlike the traditional Power over Ethernet (PoE), devices can also be cascaded using EtherCATP
and supplied with power from one power supply unit.

When designing a machine, the individual consumers, cable lengths and cable types are configured with tool
assistance and this information is used to create the optimum layout of the EtherCATP network. Since it is
known what sensors and actuators will be connected and which ones will be operated simultaneously, the
power consumption can be accounted for accordingly. For example, if two actuators never switch
simultaneously from a logical point of view, they also never need the full load simultaneously. The result is
further savings potential in terms of the required supplies and power supply units.

Basics communication

3 Basics communication

3.1 System properties

Protocol

The EtherCAT protocol is optimized for process data and is transported directly within the Ethernet frame
thanks to a special Ether-type. It may consist of several sub-telegrams, each serving a particular memory
area of the logical process images that can be up to 4 gigabytes in size. The data sequence is independent
of the physical order of the Ethernet terminals in the network; addressing can be in any order. Broadcast,
Multicast and communication between slaves are possible. Transfer directly in the Ethernet frame is used in
cases where EtherCAT components are operated in the same subnet as the control computer.

However, EtherCAT applications are not limited to a subnet: EtherCAT UDP packs the EtherCAT protocol
into UDP/IP datagrams. This enables any control with Ethernet protocol stack to address EtherCAT systems.
Even communication across routers into other subnets is possible. In this variant, system performance
obviously depends on the real-time characteristics of the control and its Ethernet protocol implementation.
The response times of the EtherCAT network itself are hardly restricted at all: the UDP datagram only has to
be unpacked in the first station.

Fig.10: EtherCAT Telegram Structure

Protocol structure: The process image allocation is freely configurable. Data are copied directly in the I/O
terminal to the desired location within the process image: no additional mapping is required. The available
logical address space is with very large (4 GB).

EK1300 15Version: 1.1

Basics communication

Topology

Line, tree or star: EtherCAT supports almost any topology. The bus or line structure known from the
fieldbuses thus also becomes available for Ethernet. Particularly useful for system wiring is the combination
of line and junctions or stubs. The required interfaces exist on the couplers; no additional switches are
required. Naturally, the classic switch-based Ethernet star topology can also be used.

Fig.11: EtherCAT Topology

Maximum wiring flexibility:
with or without switch, line or tree topologies, can be freely selected and combined.

Wiring flexibility is further maximized through the choice of different cables. Flexible and cost-effective
standard Ethernet patch cables transfer the signals in Ethernet mode (100Base-TX). The complete
bandwidth of the Ethernet network - such as different optical fibers and copper cables - can be used in
combination with switches or media converters.

Distributed Clocks

Accurate synchronization is particularly important in cases where spatially distributed processes require
simultaneous actions. This may be the case, for example, in applications where several servo axes carry out
coordinated movements simultaneously.

The most powerful approach for synchronization is the accurate alignment of distributed clocks, as described
in the new IEEE 1588 standard. In contrast to fully synchronous communication, where synchronization
quality suffers immediately in the event of a communication fault, distributed aligned clocks have a high
degree of tolerance vis-à-vis possible fault-related delays within the communication system.
