The use of EULYNX protocols to remotely control relay-based interlockings
The CTC system in northern Finland is currently being modernised. The area contains around 30 relay-based interlockings among the electronic interlockings. In order to provide a uniform interface to control the relay-based interlockings, a novel idea for an interface module that can communicate with the CTC using a modern EULYNX SCI-CC protocol and still control the Class B interlockings has been created. This article describes the technical solution and the process of implementing the interface module...
