B&R X20cHB8880 X20 hub base module
The PLCs combine high performance and numerous integrated interfaces in a housing only 55 mm wide.
That makes them only half the width of comparable devices.
Despite the high performance, the PLCs do not require any fans or batteries, making them fully maintenance free.
They come standard with two USB ports, an integrated flash memory card, POWERLINK, RS485 and two Ethernet ports.
Daisy chaining can be easily implemented with the integrated switch. The power supply is also integrated.
Additional fieldbus protocols are also available.
For this, the controllers are optionally available with a slot for interface modules.
All B&R interface modules can be combined with X20 embedded devices. Likewise, all X20 I/O modules can be connected to the controller as usual.

The interface module is used to expand the X20 CPU for specific applications.
It is equipped with an POWERLINK interface.
POWERLINK is a standard protocol for Fast Ethernet equipped with hard
real-time characteristics. The POWERLINK Standardization Group ensures
its openness and continual development.
Systems with redundant cabling can be implemented easily using POWERLINK.
Unlike ring redundancy, cable redundancy does not require cable looping,
which can sometimes be problematic. This allows the creation of all types of tree
structures. When using a device with the link selector function, data is always
transferred via the highest quality network lines. The link selector function is
integrated in the X20IF2181-2 module.
The interface module is equipped with an EtherNet/IP scanner interface.
This allows third-party components to be integrated in the B&R system and
makes it possible to quickly and easily transfer data in both directions.
The interface module can be operated in the X20 controllers or in the expandable
X20BC1083 POWERLINK bus controller.
The interface is equipped with 2 RJ45 connections. Both connections result in an
integrated switch. This makes it easy to implement daisy chain cabling.
The interface module is equipped with an EtherNet/IP adapter interface.
This allows the B&R system (I/O modules, POWERLINK, etc.) to be connected to
systems from other manufacture
