SUMMARY

Ethernet and ARCNET can be utilized in safety-critical applications, but careful consideration of the OSI model is essential to ensure reliability and risk mitigation. Safety-rated drivers and specialized PHY/MAC chips that operate in extended temperature ranges are available, enhancing the robustness of these networks. TCP/IP protocols are also feasible for safety applications, as evidenced by various implementations in critical environments, such as those highlighted by Cable LAN Nuclear.

PREREQUISITES
  • Understanding of the OSI model and its implications for network reliability
  • Familiarity with safety-rated drivers and their importance in critical applications
  • Knowledge of PHY/MAC chip specifications for extended operating temperatures
  • Basic comprehension of TCP/IP protocols and their application in safety-critical systems
NEXT STEPS
  • Research safety-rated drivers for Ethernet and ARCNET applications
  • Explore the specifications and performance of PHY/MAC chips for extended temperature ranges
  • Investigate the implementation of TCP/IP in safety-critical environments
  • Examine case studies of Ethernet and ARCNET in industrial safety applications
USEFUL FOR

Engineers, network architects, and safety system designers involved in the implementation of reliable networking solutions for safety-critical applications.

Hi,

I am curious if ethernet or arcnet are appropriate for safety critical applications. With the multiple levels of the OSI model, I assume there are many opportunities both for increasing and accidentally decreasing reliability, redundancy, and risk mitigation. Are there such things as safety rated drivers? I know that some PHY/MAC chips can be bought for extended operating temperatures. I know very little about the details of networking.

What about internet protocol like TCP/IP? Is this feasible for safety applications?
