Safety Platform for Object Controllers in Practice: Three Application Scenarios

The first integration tests ran between October and November 2025 at the Track Technology Learning Centre in Kouvola under real operating conditions. Following commissioning and configuration, the FAdP Point units delivered precise results from the outset, controlling various Siemens point machine types without difficulty, while point end-position monitoring performed as specified. The test scope also covered encrypted communication via SSI. The project experience confirms that successful multi-vendor integration depends as much on close collaboration between all stakeholders as on the technology itself, particularly around interface parameterisation and subsystem coordination.

Many markets still operate relay-based or electronic interlockings, with extensive cabling, proprietary interfaces and strong supplier dependency. A complete interlocking replacement is often not economically or operationally feasible, particularly across large, heterogeneous networks – yet operators increasingly need digital architectures to improve maintainability, scalability and lifecycle efficiency. 

Modern Object Controllers show how such a migration can be realised pragmatically. Where ageing, star-shaped cabling no longer meets availability and safety requirements, FAdP Point can take over safe control and monitoring of the point field element, while FAdP IO acts as an adapter on the interlocking side: it receives the existing electrical signals, translates them into digital signals and transmits them via RaSTA over an IP-based network to FAdP Point. The interlocking logic itself remains unchanged, as FAdP IO emulates the relevant parameters, such as operationally induced delays, of the established connection. Beyond replacing long cable runs, this approach can reduce cable breaks, insulation faults and theft exposure, while providing condition-monitoring data – currents, voltages and mechanical point machine parameters – from day one. Because FAdP Point and FAdP IO are EULYNX-compatible by design, this incremental step keeps a later, fully EULYNX-compliant architecture within reach.
