what is the difference between data store memory and goto-from blocks ?

8 次查看(过去 30 天)
in this example given in the page-> Model Global Data by Creating Data Stores
Data store memory (read/write) is used for getting the Error to switch between two values.
Instead, why can't the goto- from blocks be used ?

Hi Noufal,
the main difference is, that data store memory and read/write remove the dependency between reading and writing, i.e., the data flow: you can read and write anywhere in the model at any time.
In contrast the from-goto blocks are like having a connection between the goto and the from (it's only a different representation, instead of drawing a line you use the from/goto). But the data dependency stays intact.

Using a DSM sounds like it would give problems if it is an input into an algebraic loop.

That's a good remark: depending on how connected, execution order might be changed to have no algebraic loops ...
