I want to get the history value of a trend variable in the previous system timestep. But the built-in trend function TrendValue can only return the value of previous zone timestep. So how can I achieve this?

Any help will be greatly appreciated.

It's always a good idea to cite precisely the object you're refering to and adding a link to the doc isn't a bad idea to make the life of people who are willing to answer a bit easier. If this case I assume you're refering to EnergyManagementSystem:TrendVariable?

haha ,Yeah, Now, I use the "EnergyManagementSystem:TrendVariable" and the built-in function "TrendValue" to retrieve the history data.
