This paper presents the configuration of a SCADA based telemetry system for the main Yugoslav gas-pipeline network. A central supervising SCADA station is realized by using reliable industrial PC stations interconnected via a LAN. The key features of this SCADA are open architecture, hot stand-by, an effective MMI subsystem and an information link to the Enterprise Information System. In order to achieve better supervision and control over the gas-transport process, basic SCADA functions are supplemented with a decision support system based on trend analysis and a steady-state simulation model.
