Diagnosis of Point Machines with PLC Controller Application

December 2003 | Jakub Mly?czak, Jerzy Mikulski

Installation of a diagnostic station for point machine operation should significantly improve the process of operation and diagnosis of point machines at relatively low costs of construction of such a station. Moreover, if this station is present with the hybrid equipment or with computer panel, it could save all diagnostic messages from the event recorder for more than 3 days. Then, an overlay for the file could be created, containing data from the recorder and enabling reading out of data using a spreadsheet (such as Excel), and data filtering. It is important to create a database of malfunctions, especially for EEA-4 drive, as they require a complex operation process.
