In recent years, Alstom has relied on Systerel for the development of communication interfaces between its supervision systems and various signalling equipment.

These gateways incorporate the Safe & Secure OPC (S2OPC) communication stack designed and maintained by Systerel.

This free and secure implementation of the OPC UA protocol thus proves its ability to meet the most stringent requirements in terms of operating safety, availability and cyber security.
