Sequence Context vs. Parameters

[chris86]

Hi,

What is the best/most efficient way of communication with a VI and why? Passing down the Sequence Context, or passing parameters directly to the VI controls?

Chris,

there are two situations where you might want to use the SequenceContext as parameter (and use get/set property for data exchange) over direct parameter passing:

1) You inherit code from TS 1

2) You want to exchange more than a dozen of parameters, but, for whatever unlogical reaon, you are not willing to create nice data structures (=> clusters) out of those parameters

That being said, passing parameters directly is superior in nearly every aspect.

Hi Norbert, 

With TS 1 are you referring to a specific version of TestStand?

"That being said, passing parameters directly is superior in nearly every aspect."

Can you elaborate on this a little?

Chris,

yes, i refer to TS version 1 as in that version, it was the only way to pass parameters to LV code modules (i think in TS 2 as well, but i am not sure which version brought the "generic parameter passing").

Well, what should i elaborate? Direct parameters are faster, more secure, improve modularization and debugging (you can test your VI outside TS, no?) and create much better readable code. There are for sure additional things i forgot about.....
