DCS operation record
Thread Content
I want to check something – is it possible to find out which DCS operation station issued the command for a certain parameter?
Each DCS system has operation records
For example, if I modify parameters at Station 1#, will there eventually be a record showing that it was Station 1# that made the changes?
It can be found; it’s hard to describe exactly how to do it – just open the screen and ask an instrumentation technician to demonstrate it for you.
It’s possible. As long as something moves, there will definitely be a record of it. The DCS system used may vary, so it’s better to consult the instrumentation department in your own organization
All of these can be queried, such as PID.mode operation and PID.SP setpoint operation.
Yes, it can be queried in the operation records
Companies like Hamilton have an “offline query” function that allows users to access records of operations from a long time ago (depending on the server’s hard drive space)
