B&R X20BC00G3 X20 Series Controller

Material number:

X20BC00G3

Description:

• Fieldbus: EtherCAT

• 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 to 4 ms)

• Synchronization between the fieldbus and X2X Link

EtherCAT is an Ethernet-based fieldbus developed by Beckhoff. This protocol is suitable

for both 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 (standalone 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 added to the telegram as it is passing through.

The bus controller allows X2X Link I/O modules to be coupled to EtherCAT and operated on

any EtherCAT master system. A transition between IP20 and IP67 protection outside of the

control cabinet is possible by arranging 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).
