Hello everyone
Could you help to get know what is the different between SCADA and DCS ?

Hi Ehab,
In terms of application, DCS mostly refers to a controlling system, whereas SCADA is a data acquisition and monitoring system. However, it is a really general overview, I can say.
Following you can find some of their differences but bear in mind that their differences may not be limited to these. We will try to make a video about their differences in a more detailed approach.
1. DCS aims to control the processes which are confined in a limited area such as a factory, while the SCADA is used for vast geographical and remote systems such as 'gas transmission stations', 'water management systems' and so on.
As a result, the DCS control system's network could be a local LAN network while the SCADA communication network is somehow different. For instance, it can use a mobile network protocol. However, SCADA can be used for small industries as well, chemical industries to name one of them.
2. As I mentioned above, SCADA also can be used to control a process in addition to data acquisition and monitoring a process. However, these control loops are opened-loop in contrast with DCS systems.

Thank you, sir, for the great explanation. I am waiting for the detailed video on a similar topic.
Please! pass my request to your team to make training on this topic in detail.
Thanks again :)
Hello
first thing first, I'm so grateful and appreciated for your efforts
second thing second, I have figured out that DCS only work with LAN network, while the Scada work with other network
in addition of i think we can use both SCADA and DCS for monitoring and control : because in our factory we are using SCADA and monitoring and control not only monitoring.
Ehab,
You're welcome.
DCS is not just a single network. It can contain several different networks with a variety of protocols including Industrial Ethernet, Profibus DP/PA, Fiber Optics, etc.
Nowadays the difference between DCS and SCADA has become more blurred anyway. But aforementioned, and as you stated, the SCADA and DCS are both being used for control and monitor the plants. But SCADA is more applicable for vastly spread systems such as Gas distribution systems (CNG and LPG stations), Water distribution systems and so on.
