How does Vijeo Designer Runtime determine when to use Simulated SRAM?

Issue:
How does Vijeo Designer Runtime determine when to use Simulated SRAM?

Product Line:
Vijeo Designer (all versions)

Resolution:
Today in Vijeo Designer, there isn't any link between the data location settings and where the SRAM simulation file is actually stored. In fact, there is a series of checks that are done to determine the best place to store this internal file.

The algorithm is something like this:

if HMI has physical SRAM chip:

--> Start Runtime normally and use SRAM chip

If HMI has no physical SRAM chip:

check existence of Secondary Drive

--> If exists, store Simulated SRAM file on Secondary

--> else check existence of Optional.

--->If exists, store file on Optional

--->else error and refuse to start Runtime
