• family key
• type
• version
• revision
EK1122, EK15xx 9Version: 3.4
Foreword
Example Family Type Version Revision
EL3314-0000-0016 EL terminal

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: KKYYFFHH
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
EK1122, EK15xx10 Version: 3.4
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

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

3.1.1.1 EK1122, EK1122-0080 - Introduction
Fig.9: EK1122-xxxx
EK1122-0000
The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star
hub can be realized by using several EK1122 units in a station. Individual devices or complete EtherCAT
strands can be connected at the junction ports. The EtherCAT junctions are connected via RJ-45 sockets
with direct display of link and activity status. The Run LED indicates the status of the EK1122. Through
TwinCAT and other suitable EtherCAT masters the EK1122 also supports coupling and uncoupling of
EtherCAT strands during operation (hot connect).
EK1122-0080
Hot Connect is an EtherCAT feature for changing topologies through direct coupling or uncoupling during
operation. Coupled EtherCAT components are already quickly linked to the data communication after
connection as standard. Fast hot-connect technology further reduces the connection time significantly,
enabling even faster tool changes. Fast hot-connect ports may only be connected to each other, which is
why they are specially identified.
The EK1122-0080 EtherCAT junction with Fast Hot Connect is complemented by the EK1101-0080
EtherCAT coupler with Fast Hot Connect.

3.1.1.3 Notes re. EtherCAT Fast Hot Connect technology
EtherCAT components that support Fast Hot Connect enable a faster fieldbus boot up following the
establishment of a connection. The boot up depends in detail on the number of devices, the topology and
activated Distributed Clocks. Whereas the normal establishment of a connection and communication takes
several seconds, less than 1 second is possible with FHC components.
Properties and system behavior
• Fast Hot Connect is supported from TwinCAT 2.11R3 Build 2221.
• Fast Hot Connect ports are specially marked.
EK1122, EK15xx16 Version: 3.4
Product overview
Fig.11: Identification of FHC port at EK1122-0080 and EK1101-0080
• Standard EtherCAT devices may not be connected to Fast Hot Connect ports. This is to be ensured by
measures on the application side, which is easy to implement by means of the topology change that is
usually carried out mechanically in such applications.
Fig.12: Recommended combination of Ethernet ports
• If corresponding ports are nevertheless connected, a power reset of the devices involved (branch
terminal and coupler/box) is required.
• With Fast Hot Connect devices the establishment of an Ethernet connection is accelerated compared
to the normal Fast Ethernet connection.
If in addition the use of Distributed Clocks functions is omitted in the entire topology, then the
resynchronization time of the components is also dispensed with. Group boot up of < 1 second is then
possible, from plugging in the Ethernet connection to the OP state.
• An incorrect port allocation is detected in the TwinCAT ADS Logger
EK1122, EK15xx 17Version: 3.4
Product overview
Configuration
The configuration of Fast Hot Connect groups in the TwinCAT System Manager takes place in exactly the
same way as Hot Connect groups, specifying the associated group ID.
Fig.13: Configuration of a Fast Hot Connect group
Corresponding Fast Hot Connect ports are marked red in the TwinCAT System Manager.
Fig.14: Marking in the TwinCAT System Manager
A configuration of FHC groups is possible only if at least 1 corresponding junction is present e.g.
EK1122-0080.
EK1122, EK15xx18 Version: 3.4
Product overview
Distributed Clocks
If no Distributed Clocks functions are used, this is visible in the master settings by the absence of "DC in
use":
Fig.15: DC master setting
This setting is automatically selected by the System Manager if there are no EtherCAT slaves in the
configuration in which Distributed Clocks is activated. "DC in use" should not be randomly deactivated by the
user, because otherwise these devices will no longer function.

3.2 Junctions with M8 connection

3.2.1.1 EK1122-0008 - Introduction
Fig.16: EK1122-0008
EK1122-0008
The 2-port EtherCAT junction enables configuration of EtherCAT star topologies. A modular EtherCAT star
hub can be realized by using several EK1122 units in a station. Individual devices or complete EtherCAT
strands can be connected at the junction ports. Compared to EK1122 the EK1122-0008 has two M8 sockets
compatible to the two RJ45 sockets instead. The EtherCAT junctions are connected via M8 sockets. The link
and activity status is indicated by separate LEDs at the front. The Run LED indicates the status of the
EK1122. With TwinCAT and other appropriate EtherCAT Masters the EK1122-0008 supports coupling and
uncoupling of EtherCAT strands during operation (hot connect).
By using respective powerful Ethernet cables e.g. ZK1090-3131-1xxx distances of 100m are also possible
via M8.

3.4.1.1 EK1561 - Introduction
Fig.19: EK1561
In connection with an EK1100 EtherCAT coupler, the EK1561 single-port POF junction makes it possible to
convert from 100BASE-TX physics to 100BASE-FX physics (POF - Polymeric Optical Fiber). Distances of up
to 50 m between two couplers can be bridged using the EK1561 and the EK1541 EtherCAT coupler for POF.
Unlike the glass fiber, the POF fiber is easily wireable in the field. The Run LED indicates the status of the
EK1561.
