IMPLEMENTING INTERNET PROTOCOL (IP) BASED SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA) NETWORK SYSTEM

Abstract

SCADA (supervisory control and data acquisition) is a system that monitors and control industrial, infrastructure, or facility- based processes. Scada systems integrate data acquisition systems with data transmission systems and graphical software in order to provide a centrally located "monitor and control" system for numerous process inputs and outputs. The sensors and metering devices are connected to field control devices. These control devices take real-world physical input signals from the sensors and, convert the signals to digital data and make decisions based on programmed logic or commands from the system operators. The control devices are connected control room environments where the hmi software systems are used by system operators to interact withthe control devices. IP SCADA is a plug and play feature in the IDP 600 terminal series that allow common SACDA devices such as remote terminal units (RTU) and PLC to be connected to SCADA networks using the IsatData Pro satellite service. IP SCADA is well suited for SCADA devices that are located in remote sites where other communication services are unavailable, unreliable or cost prohibitive and for sites that have low data usage requirements. IP-based SCADA Network systems provides many benefits like Unlimited locations for servers and clients, Service takeover and remote support, Data saving & Global Coverage.
