The two DCS servers are not synchronized
Thread Content
In our chemical company’s DCS, the last two servers have been experiencing a synchronization issue of one or two seconds; what security risks does this pose to production?
It’s the server from that manufacturer; how can one detect a synchronization delay of one or two seconds?
For Hilscher, the instrument technicians will take a look at it
What is the model of the Hollyland system? Generally, it’s sufficient to synchronize the servers; it’s best to do this during times of low load or when the systems are shut down for maintenance
I’m not an instrumentation technician, so I don’t know which model it is; mainly,

I’m not an instrumentation specialist, so I don’t know which model it is; before trying to solve this problem, I want to know what risks this synchronization issue poses to the system For example, in chemical production, the main operator is supposed to operate the DCS, right? Could there be a risk of the two servers giving conflicting instructions, or other risks?
If you say it’s not synchronized, is it really not synchronized? Why synchronize? Are your wife and you also unsure about your relationship, aren’t you? Hahaha, there’s no such thing as a risk. Don’t worry. Put a piece of pork on the chest; five-flavored ones work too.
When a fault occurs, the time records of various systems do not match when trying to locate the fault
I don’t believe it; there are very few SOEs in DCS. The servers aren’t synchronized – it’s just that the timing at which trends are recorded is different. In cases where the trend changes rapidly, data is collected every 1 second, but usually it’s collected every 5 seconds or 30 seconds. A difference of 2 seconds is only a potential issue; it simply means that the trends recorded on the two servers differ by 2 seconds
