Event structure with unit change problems

[Angkrit]

Hello, how can I make the value change corresponding to the changed unit in the array?


For example, when I change the unit of "flow" to be L/hr, the value should appear from 4 to 240 in the data mainstream without adjusting the value manually. It should pop up automatically. I know how to change the unit but don't know how to make it appear in the data mainstream with the same numeric control block.

I tried to use an event structure but don't know exactly how to work around it.
