Create Multi-State limits based on tags.
On Multi-state limits, we could insert tags/attributes instead a static value. For example, a tank level:
TAG Tank Level: 333-001-233.PV
Limit Tag for 90%: TanksChemicals.LIM.HH
Limit Tag for 80%: TanksChemicals.LIM.HL
Limit Tag for 30%: TanksChemicals.LIM.LH
Limit Tag for 15%: TanksChemicals.LIM.LL
And if I have 30 tanks with the same limits on multi-state, I can change the LL limit from 15% to 10% for every one once.

Good news, this is possible already in PI Vision if you are viewing this data using an AF Element!
If you create "limit" attribute traits under the attribute representing your Tank Level, you can use PI Point data references to get the value of the limit from that PI Point. You can find more info on attribute traits here:
When you add multi-states to a PI Vision symbol for an attribute that has limit traits, the multi-state limits shown in PI Vision will automatically use the values of those limit traits. The limits are evaluated in real time with the data, so if the underlying PI Point for the limit gets a new value, it will be reflected in the PI Vision multi-state on the next update.
Very good Idea!
Very good Idea. I believe will be very useful
