Certifiable Switch for High Availability and Safety Requirements from TTTech
This 24 port switch is part of a family of rugged and certified switches that supports several Ethernet standards, including IEEE standards, such as AVB and TSN, rate-constrained mechanisms and the time-triggered SAE AS6802 standard for synchronous communication. The deterministic and fail-silent Ethernet switching engine supports synchronous communication with stringent design verification suitable for safety-critical operation and certifiable to IEC 61508.
Due to several aspects this switch marks a considerable technical innovation: It achieves reliability and fail-safe switching by implementing the entire switching functionality and management functions according to stringent development processes suitable for safety certification, and by using chip-level technologies for real-time self-diagnosis of the switching function. By doing that the switch transforms possible arbitrary failure modes in the fail-silent failure mode. This allows the building of fail-operational networks for mission-critical and safety-critical distributed applications with two channels, as each communication channel is fail-silent. Combined with the deterministic message processing capabilities, true partitioning and isolation of multiple critical traffic flows on the network are achieved.
The rugged 24 port TTEthernet switch model offers 18 ports with 100 Mbit/s and 6 ports with 1 Gbit/s. It contains a dual-core lock-step TMS570 MCU (Hercules™) from Texas Instruments that executes a set of management functions developed and certified for safety-critical operation. The switch has a 19” form factor and customization is possible.
