Discussion on little knowledge about DCS
Thread Content
On a DCS system, is it required that the system time of the operator station be the same as that of the configuration computer? If it’s different, why is that?
Personal understanding: Consistency must be maintained; the system time should be adjusted within the system itself, not directly through WINDOWS, otherwise inconsistencies will arise
First, it’s necessary to figure out which company’s DCS system it is
Of course, the requirements are the same; otherwise, when an alarm goes off, it will be impossible to know the exact time
There is no need to discuss this knowledge – the time on the controllers, operator stations, engineer stations, and servers within the same system must be consistent. In some applications where high precision in time synchronization is required, GPS is also used, enabling synchronization accuracy down to the millisecond.
It must be consistent, mainly regarding the records of alarms, operations, faults, and reports. Synchronize the time; every system has this feature……
It has to be the same, of course. If the timing of the entire system is different, then what’s the point of having any control at all?
I’m sorry, everyone! I was misled too. It’s not that the time on the engineer station differs from that on the operation station; rather, the system time is 20 minutes off from Beijing time. This is done to ensure consistency with the timing in the manufacturing processes and the upstream systems: (because the time on the upstream systems is inaccurate: hug:
