Zhongzi’s system is used for GDS, and there are currently two issues; I would appreciate it if experts could provide some guidance: alarms trigger but do not require manual confirmation to be silenced automatically； Once the human-machine interface is exited, the historical alarms cannot be found. What’s going on, and how should this be handled?
Ask the manufacturer about their after-sales service
It’s just inconvenient to ask, so I’m seeking help here
Disappearing without confirmation must be due to a direct path in the program; no SR blocks are being used. Can’t find historical records when exiting the human-machine interface? I don’t understand what you mean. Isn’t the history record section also a user interface? You’ve already quit...
Normal GDS systems require manual confirmation of alarms, via soft buttons or hard buttons. Can’t find historical alarms after exiting the human-machine interface? This is generally not possible; unless you press the confirm button after the alarm goes away, it should not disappear from the alarm panel. It is recommended that you consult the central control technician to find out how to locate the alarm.
