Product description
Dispatcher Control Technology remotely operates traction disconnectors and controls traction substations along the track. The system is implemented on Reliance and WonderWare platforms at the visualization layer and on the SAIA Burges platform at the PLC layer. The PLC collects data from the local substation. Subsequently, the data is transmitted through the technological data network by prescribed protocol according to ČSN EN 60870-5-104 into concentrators located at the electricity control room. Local controls are installed in their respective station´s office. Central remote operation is handled from the electricity control room of SŽDC´s regional directorate.
