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
Foreword
EK110x, EK15xx10 Version: 3.6
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

2 Product overview
2.1 Overview of EtherCAT couplers
An EtherCAT coupler is required in order to connect EtherCAT Terminals with E-bus-communication (series
ELxxxx, ESxxxx, EMxxxx) to an EtherCAT network. This coupler relays the communication from the higherlevel EtherCAT network to the terminals, or functions as a master itself and generates telegrams. Beckhoff
offers different components for different application scenarios.
The selection of the correct coupler depends on the following criteria:
• is a local small controller needed?
• is the coupler to be connected via copper cable or optical fiber cable?
• is the coupler to be addressed via IP or is it located in the unswitched network?
• is the coupler to be controlled via EAP (EtherCAT Automation Protocol) or EtherCAT Device Protocol?
• required protection class: IP20 or higher?
• is the coupler to be plugged in at different places at the network using the HotConnect technique?
A coupler connects the added terminals to the right; it can be connected to the higher level network to the
left. Couplers that support the EtherCAT Device Protocol ‘to the left’ must be connected there to an
EtherCAT master.

2.2 Coupler with RJ45 connection
2.2.1 EK1100
2.2.1.1 EK1100 - Introduction
EK1100 EtherCAT Coupler
The EK1100 coupler connects the EtherCAT Device Protocol with the EtherCAT Terminals (ELxxxx/ESxxxx/
EMxxxx). One station consists of a coupler, any number of EtherCAT Terminals and a bus end terminal, e.g.
EL9011.
The coupler converts the telegrams from Ethernet 100BASE-TX to E-bus signal representation in passing
with minimum latency The coupler is connected to the network via the upper Ethernet interface. The lower
RJ-45 socket may be used to connect further EtherCAT devices in the same strand.
The coupler supplies the connected terminals with the necessary E-bus current for communication. The
coupler can supply a maximum of 5V/2A. Power feed terminals (e.g. EL9410) must be integrated if more
current is required.
In the EtherCAT network, the EK1100 coupler can be installed anywhere in the Ethernet signal transfer
section (100BASE-TX). The coupler thereby processes exclusively unaddressed MAC Broadcast telegrams
of the type EtherCAT Device Protocol from the EtherCAT master. Since directed addressing via MAC
Unicast or IP addressing is not used, neither a switch nor a router can be used.

2.2.2.1 EK1101 - Introduction
EK1101 EtherCAT coupler with ID switch
The EK1101 coupler connects the EtherCAT Device Protocol with the EtherCAT Terminals (ELxxxx/ESxxxx/
EMxxxx). One station consists of a coupler, any number of EtherCAT Terminals and a bus end terminal, e.g.
EL9011.
The coupler converts the telegrams from Ethernet 100BASE-TX to E-bus signal representation in passing
with minimum latency The coupler is connected to the network via the upper Ethernet interface. The lower
RJ-45 socket may be used to connect further EtherCAT devices in the same strand.
The coupler supplies the connected terminals with the necessary E-bus current for communication. The

current is required.
In the EtherCAT network, the coupler can be installed anywhere in the Ethernet signal transfer section
(100BASE-TX). The coupler thereby processes exclusively unaddressed MAC Broadcast telegrams of the
type EtherCAT Device Protocol from the EtherCAT master. Since directed addressing via MAC Unicast or IP
addressing is not used, neither a switch nor a router can be used.
The EK1101 supports the HotConnect procedure, see EtherCAT documentation. The characteristics of the
EK1101 in relation to this are:
• ID can be set on the device via 3 rotary selector switches within the range 0 to 4095 (hexadecimal)
• the ID is readable online by the EtherCAT master via the process data
• if the EtherCAT master supports HotConnect, then an I/O group can be adopted dynamically into the
EtherCAT communication. This group can then be located at any position within the EtherCAT network.
Variable topologies are therefore easily implementable.

2.2.2.2 EK1101-0080 - Introduction
EK1101-0080 EtherCAT coupler with ID switch
The EK1101-0080 EtherCAT coupler with Fast Hot Connect technology is an extension of the EK1101
coupler.
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 EK1101-0080 EtherCAT coupler with Fast Hot Connect is complemented by the EK1122-0080
EtherCAT junction with Fast Hot Connect.

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.

• 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.11: 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

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.12: Configuration of a Fast Hot Connect group
Corresponding Fast Hot Connect ports are marked red in the TwinCAT System Manager.
Fig.13: 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.

Distributed Clocks
If no Distributed Clocks functions are used, this is visible in the master settings by the absence of "DC in
use":
Fig.14: 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.
2.3 Coupler with M8 connection
2.3.1 EK1100-0008
2.3.1.1 EK1100-0008 - Introduction
Product overview
EK110x, EK15xx 23Version: 3.6
EtherCAT coupler EK1100-0008 (M8 connection)
The EK1100-0008 coupler connects EtherCAT with the EtherCAT Terminals (ELxxxx/ESxxxx). One station
consists of a coupler EK1100-0008, any number of EtherCAT Terminals and a bus end terminal.
The coupler converts the telegrams from Ethernet 100BASE-TX to E-bus signal representation. Compared to
EK1100 the EK1100-0008 has two M8 sockets instead of two RJ45 sockets, compatible to the ones of the
EtherCAT-Boxes.
The upper Ethernet interface is used to connect the coupler to the network; the lower M8 socket serves for
the optional connection of further EtherCAT devices in the same strand.
The coupler supplies the connected terminals with the necessary E-bus current for communication. The
coupler can supply a maximum of 5V/2A. Power feed terminals (e.g. EL9410) must be integrated if more
current is required.
In the EtherCAT network, the EK1100-0008 coupler can be installed anywhere in the Ethernet signal transfer
section (100BASE-TX) except onto the switch directly. By using respective powerful Ethernet cables e.g.
ZK1090-3131-1xxx distances of 100m are also possible via M8.

2.4 Coupler with optical fiber connection
2.4.1 EK1501
2.4.1.1 EK1501 - Introduction
EK1501 EtherCAT coupler with ID switch, multimode optical fiber connection
The EK1501 coupler connects the EtherCAT Device Protocol with the EtherCAT Terminals (ELxxxx/ESxxxx/
EMxxxx). One station consists of a coupler, any number of EtherCAT Terminals and a bus end terminal, e.g.
EL9011.
The coupler converts the telegrams from Ethernet 100BASE-FX to E-bus signal representation in passing
with minimum latency The upper Ethernet interface is used to connect the coupler to the network; the lower
SC socket serves for the optional connection of further EtherCAT devices in the same strand.
The coupler supplies the connected terminals with the necessary E-bus current for communication. The
coupler can supply a maximum of 5V/2A. Power feed terminals (e.g. EL9410) must be integrated if more
current is required.
In the EtherCAT network, the coupler is used at an arbitrary place in the Ethernet signal transmission range
(100BASE-FX). The coupler thereby processes exclusively unaddressed MAC Broadcast telegrams of the
type EtherCAT Device Protocol from the EtherCAT master. Since directed addressing via MAC Unicast or IP
addressing is not used, neither a switch nor a router can be used.
The multimode glass fiber connection enables distances of up to 2 km between two couplers.
The coupler supports the HotConnect technique; see the basic EtherCAT documentation regarding this. The
characteristics of the EK1501 in relation to this are:
• ID can be set on the device via 3 rotary selector switches within the range 0 to 4095 (hexadecimal)
• the ID is readable online by the EtherCAT master via the process data
Product overview
EK110x, EK15xx26 Version: 3.6
• if the EtherCAT master supports HotConnect, then an I/O group can be adopted dynamically into the
EtherCAT communication. This group can then be located at any position within the EtherCAT network.
Variable topologies are therefore easily implementable.
