Constants on Trends
Is it possible to have a constant (i.e. a non-varying value that does not come from a historical log) display on a trend? Operators would like to see the upper spec limit and lower spec limit on the trend. Thanks

I don't know for 800xa, but in Freelance, it is possible. I just create a variable which is connected to a trend. I can affect a fixed number to this variable after...
I suppose it is the same thing in 800xa...

Afaik it is not possible in 800xA trends. But you may use 800xA basic history to log e.g. General Properties with a fixed value. You can add them to every object or use a generic object:
If you use that logged properties in your trend, you have the lines you like to see for no additional cost (no Tag count, no history count)
