CONTROLLERS – THE NEXT GENERATION

Powerful processor for future challenges in the rail sector

Anyone wishing to meet future challenges in the rail sector efficiently and innovatively has to rely on optimized development and maintenance processes as well as on homologation procedures that are as uncomplicated as possible. For this reason, it was precisely these requirements that formed the focus of the design of the new CPU 94x (Central Processing Unit) Selectron controller generation.

Equipped with a powerful processor and hypervisor operating system, it offers up to three independent virtual controllers. This allows the separation of safety-relevant and non-safety-relevant applications in one unit - simplifying TCMS architectures and vehicle approvals enormously.

Optimized for Ethernet applications with a safety and security perspective

With the three Gbit/s Ethernet ports of the "94x", you can flexibly link the device to the virtual controllers and easily integrate it into a ring structure. Each of the virtual controllers now has its own physical address. Thus, the networks are technically separated from each other and are recognized as single controllers. In terms of hardware, the CPU 94x already has various security accelerators, "secure boot" functionality and a Trusted Platform Module (TPM). Furthermore, the CPU is developed according to IEC 62443-4-2 Security Level 2 (SL2).

Selectron designed the entire software architecture in a way that the individual virtual controllers act independently of each other, also from a safety and security perspective and thus offer maximum protection for people and systems.
