- Remote devices: These are the sensors and other devices that are used to gather data from the process and send control signals to the process. They can include sensors for temperature, pressure, flow rates, and other process variables, as well as actuators that can control valves, pumps, and other process equipment.
- Communication network: The communication network is used to connect the central computer and the remote devices. This can be a wired or wireless network, and it can use a variety of communication technologies, such as serial, Ethernet, or radio.
These are the three main components of a SCADA system, but there can be other components as well, depending on the specific application.
What are the three 3 types of SCADA?
SCADA (Supervisory Control and Data Acquisition) systems are used to monitor and control industrial processes. There are several different types of SCADA systems, and the specific type used will depend on the application and the requirements of the system. Here are three common types of SCADA systems:
- Standalone SCADA: These systems are used to monitor and control a single process or piece of equipment. They typically consist of a central computer and a network of sensors and devices that are used to gather data and send control signals.
- Distributed SCADA: These systems are used to monitor and control multiple processes or pieces of equipment that are distributed over a large area, such as an entire factory or a power grid.

How to collect data from SCADA?
There are several ways to collect data from a SCADA (Supervisory Control and Data Acquisition) system:
- Polling: In this method, the central computer sends a request for data to the remote devices, and the devices respond with the current data. This method is simple and reliable, but it can be slow if there are a large number of devices.
- Subscription: In this method, the remote devices send data to the central computer at regular intervals, or when the data changes. This method is faster than polling, but it requires more bandwidth and can generate a large amount of data.
- Event-driven: In this method, the remote devices send data to the central computer only when a specific event occurs, such as a sensor reading reaching a certain threshold. This method is more efficient than Polling or Subscription, as it only sends data when needed, but it requires the devices to be able to detect and respond to events.
- Data logging: In this method, the remote devices store data locally and send it to the central computer when requested. This method is useful for collecting data from devices that are not constantly connected to the SCADA system, but it requires the devices to have sufficient storage capacity.
Which method is used to collect data from a SCADA system will depend on the specific requirements of the application and the capabilities of the system.
