The EK1122-0080 supports Fast Hot Connect technology, which

facilitates significantly shorter connection times for EtherCAT 

components with changing topologies. Compared to Hot Connect,

which is an EtherCAT feature and enables direct coupling and uncoupling

of components during system operation, Fast Hot Connect offers even

faster data transfer and allows even faster tool changes.

The EK1122-0080 has two Fast Hot Connect ports, which are implemented

as RJ45 sockets. The Fast Hot Connect ports are specially marked,

since they may only be combined with each other. The EK1122-0080

EtherCAT junction with Fast Hot Connect is complemented by the 

EK1101-0080 EtherCAT coupler with Fast Hot Connect.

The EK1122-0080 2-port EtherCAT junction can be used in an EtherCAT

Terminal segment at any desired position between the EtherCAT

Terminals and enables configuration of EtherCAT star topologies.

A modular EtherCAT star hub can be realized by using several

EK1122-0080 units in a station.

Special features:

• Connection technology: 2 x RJ45 sockets

• Connection lengths: up to 100 m

• Can be used for configuring an EtherCAT star topology

• Fast Hot Connect technology for changing topologies

The EK1122-0008 2-port EtherCAT junction can be used in an

EtherCAT Terminal segment at any desired position between the

EtherCAT Terminals and enables configuration of EtherCAT star

topologies. A modular EtherCAT star hub can be realized by using

several EK1122-0008 units in a station.

Special features:

• connection technology: 2 x M8 sockets

• connection lengths: up to 100 m

• can be used for configuring an EtherCAT star topology

The EK1122-0008 has two M8 sockets, which enable connection

of an Ethernet cable with M8 connector and establish a connection

to a further EtherCAT segment or to individual EtherCAT devices.

The M8 sockets are compatible with the EtherCAT Box modules

and therefore enables uniform cabling in the IP20 and IP67 range.

The EK1122-0008 supports coupling and uncoupling of EtherCAT

segments during operation (Hot Connect).

The EK1121-0010 1-port EtherCAT junction can be used in an EtherCAT

Terminal segment at any desired position between the EtherCAT Terminals

and enables configuration of EtherCAT star topologies. A modular EtherCAT

star hub can be realized by using several EK1121-0010 units in a station.

Special features:

• Connection technology: 1 x RJ45 socket

• Connection lengths: up to 300 m

• Can be used for configuring an EtherCAT star topology

The EK1121-0010 has an RJ45 socket that enables connection of an Ethernet

cable with RJ45 connector and establishes a

connection to a further EtherCAT segment or to individual EtherCAT devices.

With the Extended Distance connection, distances of up to 300 m can be

reached between two Extended Distance devices. If only one connection is

configured for Extended Distance, the maximum distance between the stations

is 100 m. The EK1121-0010 supports coupling and uncoupling of EtherCAT

segments during operation (Hot Connect).

The EK1110-0043 EtherCAT EJ Coupler connects the compact Embedded

PCs from the CX series and the attached EtherCAT Terminals with the

EtherCAT plug-in modules on an application-specific circuit board (signal

distribution board).

Special features:

• Connection technology: 1 x connector at the rear of the EtherCAT EJ Coupler

• Forwarding of E-bus signals and field supply to the signal distribution board

The E-bus signals and the supply voltage of the field side UP are routed

directly to the signal distribution board via a plug connector at the rear of

the EtherCAT EJ Coupler. Thanks to the direct coupling of the Embedded PC

and EtherCAT terminals with the EtherCAT plug-in modules on the PCB, no

EtherCAT extension (EK1110) or EtherCAT Coupler (EJ1100) is required.

The system and field supply of the EK1110-0043 is provided by the power

supply unit of the Embedded PC.

The Embedded PC can be extended with EtherCAT Terminals that are not yet

available in the EJ system, for example. The preassembled subsystem, consisting

of a printed circuit board with mounted DIN rail, Embedded PC and EtherCAT

plug-in modules, can be tested in advance and subsequently integrated into

the machine assembly as a complete unit.

signal representation in a continuous process. Power supply to the EK1110-0008

electronics is via the E-bus. No parameterization or configuration is required.

The EC1110 EtherCAT extension is placed at the end of an EtherCAT

Terminal segment or an Embedded PC from the CX series and offers

the option of extending the EtherCAT network in the form of a line

topology. Due to the angled RJ45 socket, the cable can be fed directly

into the cable channel without the need for a larger bending radius.

Special features:

• connection technology: 1 x RJ45 socket, angled

• connection lengths: up to 100 m

• extension of an EtherCAT network in line topology

The EC1110 has an RJ45 socket, which enables the connection of an

Ethernet cable with RJ45 plug and establishes a connection to another

EtherCAT segment or to individual EtherCAT devices. The E-bus signals

are converted to 100BASE-TX Ethernet signal representation in a

continuous process. Power supply to the EC1110 electronics is via the

E-bus. No parameterization or configuration is required.

The three diagnostic LEDs show the status of the input voltage, the output voltage, and the state of charge and indicate possible

error states.

A special feature of the Beckhoff CU81xx devices is OCT (One Cable Technology) as communication technology between UPS and

Industrial PC. This means that the two connecting lines (+24 V, 0 V) between the Industrial PC and the UPS are used not only to

supply the Industrial PC, but also for bidirectional, modulated data transmission. If both sides are OCT-capable, no further

connection, e.g., via USB, is required. This simplifies cabling and also allows longer connection distances compared to USB.

All UPS devices of the CU81xx series have permanent wiring via two 9-pin plugs, so that the wiring does not have to be

disconnected during service.

Note: Please refer to the product documentation for the retention times that can be achieved with the UPS and important

information on installation and safe operation of the devices.
