(Supervisory Control And Data Acquisition) represents a computer system for monitoring, measuring and managing industrial systems. Every industrial process that makes sense to automate is a great candidate for SCADA implementation.
These systems have existed in various forms since the 1960s, and since the 90s of the 20th century they have experienced a great expansion with the emergence of ever faster and more efficient computer and microcontroller devices. They can be used for easy monitoring (eg temperature, air humidity, pressure), as well as for complex control and control (eg production processes in factories or regulation of rail and road traffic).
The SCADA system typically consists of:
- transducers and actuators
- RTU (Remote Terminal Unit)
- communication networks
- central cells.
- Convertors and actuators represent the beginning of the chain. They are electrically or mechanically linked to the process we are observing. The task of the transducer is to monitor the values of pressure, flow, temperature, speed and that in analog or digital form information about the current state of the measured size is forwarded to the RTU. Actuators receive information from the RTU and, for example, close or open the valves.
Loading from Scada:
Through the default time intervals, SCADA systems read the measured data and insert it into EPAnet for simulation. For a successful simulation, initial settings are first set (such as the current water level level in the water level, the current state of the valve (open / closed), pump status …) that are downloaded with the downloaded data.
