Beckhoff CX7051 | Embedded PC with Arm® Cortex®-M7, CANopen responder (slave) and integrated I/Os

The CX7051 Embedded PC has an Arm® Cortex®-M7 single-core processor

with 480 MHz. In the basic configuration, the CX7051 has a slot for a microSD

card and an Ethernet interface. As a special feature, the CX7000 series has

eight integrated multi-functional inputs as well as four integrated multi-functional

outputs. The CX7051 has a CANopen responder (slave) interface.

E-bus or K-bus terminals can be attached as required; the CX7051 automatically

recognizes the type of I/O system connected during the start-up phase. 

The control system is programmed with TwinCAT 3 via the Ethernet interface.

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 EK1101-0080 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.
