On the computer, the DCS control valve suddenly switched from manual to automatic mode, and then returned to manual mode after a few seconds. What’s going on?

The computers in our facility’s control room are equipped with ABB DCS systems. Sometimes, the manual control of the control valves on those computers suddenly switches to automatic mode, and then it returns to manual mode after a few seconds. What could be causing this?
Contact your instrumentation department to check; whether it was changed to manual mode or cascade mode, it should all be recorded on the engineer station~~~~
How do I get to the engineer station? Please give your advice
Only instrument professionals can enter the engineer station; ordinary operators cannot! Have an instrumentation specialist take a look!
Your company has them, but even if you’re allowed to go in, you won’t be able to find them~~~ Professional maintenance personnel are needed to get in~~~
To enter the engineer station, a password is required, which only the instrument operators have……
Why not ask the instrumentation technician to handle this situation? What if you cause problems by trying to do it yourself!
It’s so amazing – it can switch automatically between manual and automatic modes
Has a trigger mechanism been set up?
The engineer station is where the instrumentation engineers handle things; operators definitely cannot operate it, as they don’t have the necessary permissions.
