Database server
I/O system
PLC controller
Sparger controller
Answer is Right!
Answer is Wrong!
The correct answer is D. Sparger controller.
A SCADA system is a supervisory control and data acquisition system. It is a computer-based system that collects and monitors data from remote locations and then uses that data to control devices at those locations.
The main components of a SCADA system are:
- A database server: This stores the data collected by the SCADA system.
- An I/O system: This is the hardware that is used to connect the SCADA system to the devices that it is monitoring and controlling.
- A PLC controller: This is a computer that is used to control the devices that the SCADA system is monitoring.
- A HMI (human-machine interface): This is a software application that allows operators to view the data collected by the SCADA system and to control the devices that it is monitoring.
A sparger controller is a device that is used to control the flow of gas into a sparger. A sparger is a device that is used to add gas to a liquid. The gas is added through small holes in the sparger, and the bubbles of gas help to mix the liquid.
A sparger controller is not a component of a SCADA system because it is not used to collect or monitor data, nor is it used to control devices.
