SCADA

Sisteme SCADA (Supervisory Control And Data Acquisition)

Economic and operational advantages offered by SCADA systems

Economic benefits:

• Reduction in system losses,

• Reduce labor costs

• Reduced capital costs through resource efficiency,

Operational advantages:

• Reliability and quality greatly improved the services provided,

• Reduce maintenance activities necessary

• Better use of labor

• Technical information and much improved planning

Types of inputs and outputs:

• Digital inputs/status: the min/max, state of valves, pumps, etc. status.

• Digital output/control: pump operation (ON/OFF) position valves (closed/open),

• Analogue Inputs: level or pressure inside tanks/reservoirs, intermediate positions of valves,

• Analog outputs: Continuous control valves,

• Intelligent Sensor Interface RS-485 (monitoring electric parameters, temperature, etc..)

SCADA systems based on radio communications, is the most efficient solution for:

• distant and underserved by the operators locations, with difficult access for operation and maintenance.

• for systems with a large number of stations, which raises problems for up-date, configuration or parameters modifications, or when it’snecessary to diagnose hardware or software problems on each station.

• for stations located in difficult conditions (wide range of temperatures, high humidity, acid, etc..).

• SCADA system can be configured to send text messages (SMS) to Tetra terminals (portable or mobile)
