Functional safety with netX

Safety device integration:

The netX technology platform supports the development of devices that have to meet high functional safety requirements. Our firmware provides the data packets for the desired security-relevant applications. These include Safety over EtherCAT, CIP Safety or PROFISAFE, for example. netX employs the Black Channel principle for system-safety-relevant communication.

This ensures that your security requirements are met while relying on Hilscher’s reliable protocol hardware and software.

We work closely with experienced partners to implement safety layers for your device. Ask us how we can help you with your next project.

Hardware setup for SIL3 devices:

On the hardware side, as with non-safety devices, netX serves as the interface to the fieldbus or real-time Ethernet systems.

The example shown here shows a SIL3 implementation based on a 1oo2 (one out of two) approach.

The safety frames are treated like I/O data and forwarded to the safety-relevant application. For example, the corresponding application firmware for the netX 90 can be implemented on the application side of the controller. It retrieves the data packets from the Dual Port Memory (DPM) and forwards them to a defined interface (shown as a serial port in our example). On the safety side, two redundant CPUs then receive the data via a galvanically isolated serial interface for further processing.

We can help you develop your safety-critical application.
