B&R presents a new generation of X20 controllers with Intel Apollo Lake I processors. The new controllers are distinguished by significantly higher performance, additional RAM and integrated onboard flash memory. In addition, this generation of controllers supports OPC UA over TSN and can be used as a field-level master in corresponding networks.

  • Highlights
  • Supports OPC UA over TSN
  • Broad power spectrum
  • With or without CompactFlash

The new controller generation offers considerably more processing power than older X20 generations with the same compact design. The controllers are equipped with high-speed Intel processors and enable cycle times as fast as 100 µs. They also offer a large L2 cache, a faster floating point unit (FPU) and faster RAM access for optimal command processing.

Integrated flash memory

The new X20 controller generation has integrated flash memory. This allows them to be optionally operated without a CompactFlash card. In this case, the integrated flash drive replaces the functionality of the CompactFlash card.

As with all X20 controllers, up to 250 I/O modules can be connected directly to the controllers and line up seamlessly. The entire system saves a large amount of space in the control cabinet. Even with its compact design, the controller has a built-in power supply for itself and the connected I/O modules.

POWERLINK, TSN-enabled standard Ethernet, CAN, RS232 and USB are available as integrated interfaces. Additional interfaces can be added via interface modules.
