Re: Is there any way to have more than 28 connection terminals?

[Jared Aho]

Hey Gonzo,

My first thought is that you really might want to reconsider this VI
that you are developing. Is there another way that you could design it
such that it does not require more than 28 inputs/outputs?

Some other information that could be useful: what do you plan on
calling this dll from? just how many inputs and how many outputs are
you looking at?

There is an example in the NI Developer which talks about using a
structure in a dll to correspond with a cluster in LabVIEW. http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3DD8F56A4E034080020E74861&p_node=DZ52048";>Using
Structures in a DLL with Clusters in LabVIEW If it's possible, try
and take a look through the example and see if this option could work
for you.

I have used clusters before and would love to use them in this case.
The only problem that I am finding with this approach as it applies to
my situation is the parameters contained within the cluster (inputs)
are not recognized by the application builder when creating the DLL.
Unless I have overlooked something... I do not think the cluster
approach will work. Any other thoughts

It seems that you have two limiting factors. 1) LabVIEW does not allow
for more a 28 terminal connector pane, and 2) the software interface
on the other system.

There is not going to be a way to increase the number of terminals in
LabVIEW. You should definitely look into using clusters. You=92ll be
able to consolidate your controls so that only a single terminal pin
is used. Then you will be able to extract those controls and perform
whatever type of manipulation on them individually.

I wouldn=92t think you would have any problems with this type of coding
with your software interface, but that=92s something you will have to
investigate.

I am using the application builder to create DLL's for a futures
trading system and want a few more than 28 input/outputs... is this
possible? I would pass arrays... but, the software interface on the
other side is limited and cumbersome. If I could have 40 terminals,
for example, my needs would be met when building these DLL's. Any way
to do this? Any way to create a DLL with more than 28 input/outputs?
