How can I manually enter a value in a flowchart and record it in the history trend? Thank you!

I would like to ask the experienced colleagues how to manually enter a value in a flowchart and record it in the historical trend data. Thank you!
Your question isn’t described accurately – a single value by hand?

Can this value exist independently in the history, without relying on a meter? This value is an experimental test value; since it is related to the parameters of multiple instruments, I want to record it in a trend chart so that I can identify some patterns within it.
I see; it’s about manually entering parameters, but you also want to record those entered parameters. This can be achieved by setting a constant block in the program to allow for manual input ； Connect the output of this constant block to a variable for display, and then reference this variable in the trend view
Create an indicator PVI; use the experimental test values as input for the indicator PVI, and the PV value of the indicator PVI is recorded in the trend.

Thank you! :handshake
Thank you! :handshake
Where is the PVI function block? How come I couldn’t find it? I’m using PKS.
Could you explain it in detail? I’m using PKS, thank you!
