EULYNX Architecture

The EULYNX architecture is based on a modular approach, where the interlocking system communicates with object controllers via standardized SCI interfaces.

Each Object Controller is responsible for the safe operation of a specific type of field element, whether it be a signal, a point, or a level crossing.
