1.1 Description of the ECX-EC

Block circuit diagram
The ECX-EC EtherCAT Slave Bridge connects two EtherCAT segments. Therefore the EtherCAT
slave bridge implements two separate EtherCAT slave interfaces for integration into two EtherCAT
networks. The bridge allows EtherCAT process data exchange between the networks.
For synchronization of Distributed Clocks (DC) the ECX-EC offers the exact difference between the
two slave time stamps as CoE object to allow one master adjusting its time to the other.
For DC synchronization in the redundancy case the ECX-EC bridge is used as first and last slave
simultaneously, which allows the master to keep all slaves synchronized in both segments.
Additionally the ECX-EC comes with an Ethernet interface, that can be used as Ethernet over
EtherCAT (EoE) Switch Port.
The ECX-EC is a compact hat-rail module designed for carrier rail mounting (TS 35).
The 24 V-power supply can be applied via a connector with spring-cage connection or optionally
via the InRailBus connector (TBUS-connector) integrated in the mounting-rail.
Furthermore, an optional CAN interface can be realized, accessible via the InRailBus connector.
The 100BASE-T-EtherCAT interfaces are designed according to IEEE 802.3.
The ECX-EC can be configured by typical network configuration tools (e.g. esd Workbench,
TwinCAT
®
, etc.).
INFORMATION
The enclosed ECX-EC-CD contains the documentation, the EtherCAT Workbench as
network configuration and diagnostic tool for EtherCAT networks and the esd Software
UDDC (Universal Description Composer).
