The Swiss company VT Verkehrs- und Industrietechnik AG (VT AG), experts in track and points construction, were faced with the task of modernising the central control and monitoring system for eight points of varying types. They worked with Pilz to develop a generic solution based on the automation system PSS 4000-R for railway applications. The result is a centralised controller for all types of points.
Generic controller for various types of points
A transferable control solution
Malfunctions can arise quickly if points are set incorrectly. So it was all the more important to the operators of the Dolderbahn and Rigi Bahnen AG that the points controller be upgraded to the state of the art and comply with the applicable CENELEC standards. There are eight points in total, made up of three different types, which had previously been controlled differently; that proved a challenge. VT AG and Pilz worked together to develop a generic solution: The automation system PSS 4000-R with the corresponding I/O modules, located in the control box alongside the tracks, is now used for centralised control and monitoring of the points. The advantage of this generic control solution is that it only needs to be certified once and in future can be transferred to other types of points. In this way the innovative retrofit ensures that operational processes run smoothly.
The benefits at a glance:
- The automation system PSS 4000-R is modular in design and is suitable for digital control and retrofit tasks
- The control solution only needs to be certified once
- Pilz offers a holistic service – from software development and validation to commissioning and documentation
“From our side, we would not want to go without the technical competence, the in-depth standards’ knowledge and pleasant personal contact that we enjoy with Pilz”
