Supervisory Control and Data Acquisition (SCADA) is a comprehensive computer system for gathering and analyzing real time data. Since the advent of programmable logic controllers (PLCs) in the late 1970s, the individual components that comprise a SCADA system have been dramatically reduced in size and cost. Widely used in municipal and industrial processing, SCADA systems monitor and control a plant or equipment in industries such as telecommunications, water and wastewater control, energy, oil and gas refining, and transportation. Typically, these clients have operations that are distributed across large geographic areas with multiple facilities. While the PCLs collect the data, operations and maintenance staff are still integral to the process. Remote monitoring by data center personnel is managed via human-machine interface (HMI) software. Maintenance and operations requirements that must be managed by staff and are relayed by a variety of communication options, such as radios, cell phones, and satellite technology operating on licensed and unlicensed frequencies. This network of communications devices provides continual communication between operations, maintenance, and data center personnel to ensure that all systems run at the optimal level.
