I'm trying and working with TS3 since about a year. Constantly switching
between 'Woow, what a great product' and 'What the heck do they mean with
that' resp. 'What was the name of that damned variable?'.

It is quite easy to call a VI and to pass data between both sides.
There are two ways.
1. You can pass an activeX ref to the VI and use SubVIS to pass data
between LV  TS. There are several examples in TS.
2. You can define locals, parameters and different types of globals in TS
and 'connect' those with fitting data types on the connector pane of the
VI. This works only in the cooperation of TS3 and LV7, AFAIK. 
But an update to Dev Suite Test Edn is higly recommended as it costs not
soo much more than simply buying TS alone and you get amoung others a one
year SSP.

I still can not tell you if TS is worth its costs _for_us_. It is a really
complex product. But is is for sure not as easy to handle like NIs
marketing tells us. 
The best 'poor comparision' I have found is TS is like a helicopter - a
very powerfull tool, but one needs a lot of expertise to operate it.

And, what I am troubled most with, is, it is much more C-related than
LV-related. So often I end transfering even simple processing into a simple
VI rather than doing it in TS, because of my missing C competence.

There is a rather dead Info-TestStand and a more frequented forum on NIs
pages for TS. 
But until now I was unable to find anyone here in Germany that is using TS
and is willing to share competence like here on this list.
I hope for the German NI Days VIP2004 in March...

RE: Teststand 3.0 question

2004-01-30 Thread Scott Serlin
Thanks for the info Uwe.  I'm still debating whether to use this tool or
not.  I do like many aspects of it but with only 30-days to evaluate it
and being pressed for time on my other projects, I just can't tell.
Since one has to have certain variables coming out of the VI in order
for teststand to communicate with the VI, I have to modify a lot of my
previously written code.  Also very time consuming.  Can you elaborate
more on this statement of yours below.  So if I understand you
correctly, I cannot use LV6.1 to do this?   I have some old machines
that don't have the harddrive space to accomodate LV7.1.  I would have
to update their harddrives which is simple to do but do I want to pump
more money into an ailing machine or just go out and get a few new ones.
After a while, it doesn't make sense to put money into an outdated
machine.

2. You can define locals, parameters and different types of globals in
TS
and 'connect' those with fitting data types on the connector pane of the
VI. This works only in the cooperation of TS3 and LV7, AFAIK.

Teststand 3.0 question
