In the future, the development of DCS should probably move in the direction of wireless communication, right? Let’s discuss it

The current DCS control is good too, but wireless must be the trend, right?
For wireless DCS transmission, stability, reliability, and noise resistance are key areas of focus.
Yeah, stability is an issue.
Could there be signal interference between adjacent factories? Or the attenuation is severe at greater distances
Improving stability is one direction.
No matter how advanced wireless communication becomes, it cannot replace wired connections
Reliability is the most crucial aspect in industrial control. With the current level of wireless transmission technology, it is likely difficult for such technology to be used in industrial control applications. Of course, large foreign companies have long been promoting and popularizing wireless technology for field instruments, and many users are employing it; however, the results are said to not be entirely satisfactory.
Wireless communication suffers from signal latency (reported to be 6–8 seconds), and can only be used for online monitoring (such as level monitoring in tank areas); it still presents problems when used in control circuits
It seems that wireless transmission can be used in unimportant situations, like?
It is said that most of the monitoring relates to tank areas
