Power supply terminal

EtherCAT Terminals (E-bus) or Bus Terminals (K-bus) can optionally be connected directly on the right-hand side; the CX7050 automatically recognizes which system is connected during the start-up phase.

K-bus interface

The CX7050 reads out the terminal types during scanning and creates them in the System Manager under a Bus Coupler.

Power supply terminal 1:
K-bus interface of a CX7050 in the TwinCAT System Manager.

For K-bus diagnostics there is a status variable in TwinCAT under the Bus Coupler, which can be used for diagnostic purposes and indicates the status of the K-bus communication. For more information, refer to the chapter "Error handling and diagnostics" at K-bus.

E-bus interface

Power supply terminal 2:

Distributed clocks

The Embedded PCs of the CX7000 series are not suitable for the use of EtherCAT slaves that use distributed clocks or require them.

The operation of EtherCAT Terminals and EtherCAT devices is also possible at CX7050. The CX7050 also recognizes these terminals automatically during scanning, reads out the terminal types and creates them in the System Manager under an EtherCAT Coupler.

Power supply terminal 3:
E-bus interface of a CX7050 in the TwinCAT System Manager.

For more information on diagnostics, refer to the chapter "Error handling and diagnostics" at E-bus.
