PLC vs SCADA
PLC (Programmable Logic Controller)
We get to know that what is PLC by its Name. If we talk about the use of PLC, then Suppose I have a Machine, now I want to run this Machine for 1 hrs, then close 1 min and run it for 1 hrs, then close 1 min and this process continues throughout the day. So in this way the machine control can be done easily with the help of PLC.
We can control any electrical equipment according to us with the help of PLC, to do this we only have to do programming in the software of PLC, after that the device starts running according to the way we have programmed it.
What is SCADA
The full form of SCADA is Supervisory Control and Data Acquisition (Supervisory Control and Data Acquisition).
SCADA is used to supervise our equipment. Example- Suppose we have 10 motors in our company, how long are those three motors running and how much Ampere current they are taking, SCADA takes care of all these things. In the name of SCADA, Data Acquisition means to store the data.
SCADA has two main functions.
- First of all, SCADA does the work of monitoring our system. Meaning it monitors all of what is happening inside our company. For example, which motor of our company is running and which is not running, Apart from this, how much ampere current is that motor taking. We are able to monitor all these things with the help of SCADA.
- Apart from this, SCADA works to store the data of our system. Example- Suppose if our company has three motors, and we want to know how many hours these three motors have run in the whole day, and which motor has been off for how many hours, then we can easily find out all these points with the help of SCADA. can. So in this way SCADA also works to store the data of our system.
