4.5.11.1 General information
EtherCAT is an Ethernet-based fieldbus developed by Beckhoff. The protocol is suitable for hard and soft real-time
requirements in automation technology. In addition to a ring structure, which becomes logically necessary because
of the summation frame telegram used, the EtherCAT technology also physically supports topologies such as line,
tree, star (limited) and combinations of these topologies. B&R's X20BC80G3 (expandable bus controller module)
and X20HB88G0 (stand alone junction base module) are available for implementing these topologies.
EtherCAT slave devices take the data designated for them from a telegram as it is passing through the device.
Input data is also inserted in the telegram as it is passing through. The X20BC00G3 bus controller allows X2X
Link I/O modules to be coupled to EtherCAT and can be operated on any EtherCAT master system. A transition
between IP20 and IP67 protection outside of the control cabinet is possible by aligning X20, X67 or XV modules
one after the other as needed at distances up to 100 m.
Master systems without FoE (File Access over EtherCAT) support require an appropriate configuration tool to
transfer the configuration (optional).
•

Auto-configuration of I/O modules
•
I/O configuration and firmware update via the fieldbus (FoE)
•
Full support of the modular slice concept via CoE (CANopen over EtherCAT)
•
Configurable I/O cycle (0.2 - 4 ms)
•
Synchronization between the fieldbus and X2X Link
•
X20BC80G3 module type with two additional output ports (X20HB28G0)
Information:
Only the default function model is supported (see respective module description) when the bus con-
troller automatically configures multi-function modules.
All other function models are supported when configured accordingly (see EtherCAT user's manual).
