The EKM1101 EtherCAT Coupler connects the ELMxxxx EtherCAT measurement modules

with EtherCAT. Such a station consists of an EKM1101 coupler, any number of EtherCAT

Terminals and a bus end cap or an EtherCAT extension such as EK1110 or EK1122. 

The coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal

representation.

On account of three significant properties, the EKM1101 and the functionally identical

ELM9410 power supply terminal are designed to meet the needs of high-precision analog

measurement technology, e.g. with ELM3xxx terminals:

• To reduce interference in the connected terminal, both the E-bus supply US and the 24 V

power contact supply UP are electrically isolated and filtered in the coupler. 

The power contact supply can carry a maximum load of 2 A.

• The extensive voltage and temperature monitoring provides assistance with commissioning

and operation. Results are displayed by LED and in the process image.

• The built-in three-axis position and vibration sensor allows a constant view of the mechanical

situation in the control cabinet.

As a result, the EKM1101 can be used in special measuring situations instead of the conventional

EK1100 EtherCAT Coupler. Mixed operation with EL9410 is possible, but this negates the concept

of electrical isolation. The EKM1101 has two hexadecimal ID switches for assigning an ID to a

group of EtherCAT components. This group can then be located at any position within the EtherCAT

network. Variable topologies are therefore easily implementable.

The EK1101-0080 supports Fast Hot Connect technology. This facilitates significantly faster connection of the EtherCAT components

in applications 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 EK1101-0080 has two Fast Hot Connect ports in the form of RJ45 sockets and three hexadecimal ID switches. 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 can be used to configure a star topology.

The system and field supply, each 24 V DC, is provided directly at the coupler. The attached EtherCAT Terminals are supplied with

the current required for communication from the supplied system voltage. The coupler can supply a maximum of 5 V and 2 A. If

higher current is required, power feed terminals such as the EL9410 have to be integrated. The field supply is forwarded to the

individual I/O components via the power contacts with up to 10 A.

The EK1101-0080 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the EtherCAT Terminals. The

coupler converts the passing telegrams from Ethernet 100BASE-TX to E-bus signal representation. A station consists of a coupler

and any number of EtherCAT Terminals that are automatically detected and individually displayed in the process image.

Special features:

• Connection technology: 2 x RJ45 socket

• Connection lengths: up to 100 m

• Fast Hot Connect technology for changing topologies

• Number of EtherCAT Terminals in the overall system: up to 65.535

The EK1101-0010 has two RJ45 sockets and three hexadecimal ID switches. The upper Ethernet interface is used to connect the

coupler to the network; the lower socket serves for the optional connection of further EtherCAT devices in the same segment. 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. A group of EtherCAT

components is assigned a unique ID via the hexadecimal ID switches. This group can then be located at any position within the

EtherCAT network. Variable topologies are therefore easily implementable. In addition, an EtherCAT junction or an EtherCAT

extension can be used for the extension or for setting up a line or star topology.

The EK1101-0008 has two M8 sockets. The upper Ethernet interface is used to connect the coupler to the network; the lower socket

serves for the optional connection of further EtherCAT devices in the same segment. The M8 socket is compatible with the EtherCAT

Box modules and therefore enables uniform cabling in the IP20 and IP67 range. A group of EtherCAT components can be assigned

a unique ID via the hexadecimal ID switches. This group can then be located at any position within the EtherCAT network. Variable

topologies are therefore easily implementable. In addition, an EtherCAT junction or an EtherCAT extension can be used for the

The EK1000 EtherCAT Coupler supports EtherCAT communication via switched Ethernet networks, such as TSN networks (Time

Sensitive Networking), and allows for connecting various EtherCAT Terminals from the wide range of I/Os with standard network

technology.

The EtherCAT Open Mode protocol enables communication via a layer 2 or a UDP connection. Via UDP, EtherCAT data can also be

addressed across routers.

The EK1000 is TSN-ready and can be made TSN-capable by a firmware update when the TSN technology is available. Proven

EtherCAT features, such as distributed clocks and XFC, can also be used within a TSN network. In addition, it allows for connecting

EtherCAT-capable drives that do not have a TSN-capable interface.

Thus, the EK1000 effectively links EtherCAT and TSN networks, combining their benefits: EtherCAT provides a real-time capable

single-device level and is therefore ideally suited to combine the numerous small data packets that come from the digital and

analog inputs and are typical of industrial environments into a complete process image. TSN, on the other hand, defines a physical

layer, which only relates to the switch layer in switched Ethernet networks. As a real-time extension of the general Ethernet

technology, it controls the procedures and priorities for the transport of Ethernet telegrams through a TSN-capable, switched

network.

The EtherCAT Coupler has two RJ45 ports. One of these 100 Mbit/s ports connects the EK1000 to the Ethernet or TSN network. The

second port enables EtherCAT network extensions, e.g., via the EK1100 EtherCAT Coupler.

The EK1000 extends the TwinCAT automation software with a TSN-capable version of EtherCAT communication. In this way, TSN

networks can also be managed seamlessly, and EtherCAT devices located in different terminal strands can be addressed via the

TSN network.
