Connectivity options and secure communication

Frauscher Connect

Versatile connectivity manager for secure, standard-compliant communication

Frauscher Connect is a versatile connectivity manager for all Frauscher systems, offering various connectivity options and secure communication based on EULYNX and System Pillar standards. It enables open network communication in compliance with CENELEC cat. 3 standards and ensures secure, non-reactive data transfer from OT to IT networks.

Benefits at a glance

Extensive options for secure communication

Standardised EULYNX interfaces: SSI, SDI, SMI

OPC-UA aggregator

Data diode for network separation

Simple and flexible configuration

Local SMI as alternative for MDM server

Frauscher Connect: One-stop security solution

Frauscher Connect ensures secure and reliable communication between Frauscher object controllers and signalling systems. It manages the secure transmission of commands and messages (SCI), diagnostic and maintenance data (SDI & SMI), and security services (SSI) for Frauscher EULYNX subsystems, intended for purposes such as train detection and point control.

Frauscher Connect provides multiple security options, including TLS over TCP for RaSTA and OPC-UA communication, as well as tunnelling for TDS-to-TDS connections. It's simple and flexible configuration allows it to function as a connection manager for Frauscher train detection and point object controllers, efficiently handling multiple RaSTA connections.

Future-proof standardisation: EULYNX protocols

Frauscher Connect utilises interfaces that are developed in accordance with the EULYNX Baseline 4 standard, ensuring seamless communication with interlocking systems, Maintenance and Data Management (MDM) servers, and security platforms. The system supports communication up to cat. 3 networks, providing a secure and robust connectivity framework.

Adhering to standardised interfaces prevents proprietary lock-in, promoting flexibility and compatibility across various technologies. By supporting EULYNX specifications, Frauscher Connect optimises the integration of Frauscher's Point Control and Train Detection systems, streamlining railway operations.

Connectivity manager for Frauscher solutions

Frauscher Connect is a dedicated connectivity manager for all Frauscher systems, including the Point Control and Train Detection systems. It is responsible for the establishment of secure communication over open networks with external systems and Frauscher Insights.

Cyber security without compromises

Ensuring safety and security in railway operations is crucial: Frauscher Connect supports category 3 networks as per EN 50159, integrating advanced cyber security measures to safeguard data. By utilising Ethernet-based communication, it reduces the need for extensive cabling, thereby cutting installation and maintenance costs whilst streamlining the entire process. The necessary infrastructure is integrated via the Security Service Interface (EULYNX SSI-XX) which provides all the necessary functions for secure data transmission (TLS over TCP).

OPC-UA communication for diagnostic and maintenance

In accordance with EULYNX, the OPC-UA protocol is used to enable the transmission of diagnostic data to the Maintenance and Data Management (MDM) servers. Application specific communication is structured according to the Standardised Diagnostic Interface (SDI) data model and ensures a systematic and efficient exchange of information.

Furthermore, the OPC-UA standard is used to enable the transmission of maintenance data for updates, patches or new configuration files from an MDM server to the object controller. If no MDM server is available a local MDM software provided by Frauscher can take over this role.

One way, maximum security

Data diodes enforce the unidirectional transmission of data and ensure a secure transfer from the OT network to the IT network without the risk of data leaks or cyber attacks from the IT side back to the OT network. Using this approach, Frauscher Connect warrants the integrity and security of critical railway operations while enabling the necessary data flow for preventive and predictive analyses. This in turn results in efficient maintenance, lower life cycle costs and smoother operations.
