As a platform....

Since 2007, the integrated control and monitoring system for the Platform Screen Doors (PSDs) on Seoul Metro lines 5, 6, 7, and 8 has continuously added new stations that were built after its first release. In August 2024, the PSD monitoring system for 6 stations on the Byeollae Line was added.

The Data Service Platform by Cnix, installed and operated by Seoul Metro, has so far successfully fulfilled its role as a platform. Cnix is planning to phase out the current version of the PSDCS (PSD Control System) and is preparing a new version of the PSDCS that will increase data speed by more than 30 times.
