SCADA is a terminology widely used to describe management and control solutions in a broad #IndustrialSectors.
Specifically, some of the #industries where SCADA is typically found in applications. These include #Environmental Control Systems, Mass Production, #Electric #PowerPlant, #Mass Transit Systems, #Manufacturing Systems, #WaterManagementSystems, and #TrafficControlSignals.
SCADA as an #AutomationSystem Tool
SCADA is an acronym for #Supervisory #Control and #Data #Acquisition. Indeed, there are numerous parts of a working #SCADAsystem found in a #ControlNetwork.
A SCADA system typically takes/receives #signals from the #hardware of the Input/output #modules, #communications equipment, networks, #controllers, user interface (HMI), and software. In a more extensive term, SCADA refers to the whole central system.
Moreover, this central system is responsible for #monitoring information from different industrial #sensors found in the control system (i.e both on the field and in close #proximity).
*SCADA as a User Interface System*
A SCADA #configuration system comprises a user interface generally known as #HMI (#Human #Machine #Interface). The SCADA framework is where information received is processed. Also, it offers ease of monitoring and viewing process by the human operative.
Further, this interface typically includes flexible controls interface where operators could interact with the SCADA system. Essentially, HMIs provides a simple approach to standardizing the appropriateness of #displaying and monitoring many PLCs or RTUs.
Ideally, the PLCs or #RTUs will execute the pre-#programmed processes, while monitoring the entire system/#plant individually could be difficult. This is due to the fact that they’re distributed over the scheme.
Historically, PLCs and RTU systems had no flexible technique to display or present information to an operator or industries #supervisors. Notably, the SCADA system is configured and linked with PLCs to the entire network system via a suitable #communication #protocol.
Conclusion
Therefore, #operators can easily interface with the process control via the HMI while the #plant processes information via the quality control.
