Procurement Record

Description

The Public Transport Authority’s (PTA) Operational Technology branch currently maintains a number of Programmable Logic Controllers (PLC) which provide monitoring capability of critical station and rail infrastructure across the Metropolitan area. These PLCs vary in both age and criticality with the most current device installed as part of the Mandurah Line Rail extension in 2007. This procurement aims to replace obsolete and out of support hardware, while leveraging enhanced functionality to meet evolving business needs for the monitoring of field assets. Additionally, this initiative will provide a level of standardisation across the existing asset base by establishing consistent PLC design and software programming standards. This will also aid in future projects and offer a simplified path for subsequent upgrades. The PTA seeks to replace 59 PLCs and several sites across its metropolitan railway network.
