Safe Train Control Applications

A general purpose platform for safe train and wayside functions

duagon SAFE CONTROL is a general purpose platform for safe train and wayside functions based on standard technologies – and as such open to the features and requirements of the final application. Several packages and services around d-SC help the customer to save costs and speed up time-to-market.

SIL4-Certified (EN5012x) Railway Computer for Rolling Stock and Trackside Applications

  • Certified functional safety

  • Product architecture: duagon SAFE CONTROL (d-SC) controller (with safe CPU) and safe I/O

  • Modularity in I/O configuration

  • Software architecture: separate domains for safe and non-safe software applications

  • Real-time Ethernet communication: Safe communication via FSoE

  • Process data application framework (PACY) – makes hardware transparent for the application

  • High availability software layer to enable customer applications with two redundant d-SC controllers

Application Examples
