creating and loading 4000 shared variables

[Paul Braho]

I need some help laying out the design of this system.  The data is coming over reflective memory.  I've written a dll and a simple server to do the interface between the reflective memory and shared variable engine.  Everything seems to be working.  The problem I am having is with scaling the application up to handle approximately 4000 variables.  I have a spreadsheet to manage the reflective memory allocation and can use it to import the shared variable definitions with the names from the system that is writing the data.

I am having trouble deciding on the best way to proceed.  I would like to read a buffer from reflective memory instead of reading 4000 times.  I also would like the server to read in a file that defines the association between the shared variable and reflective memory address.  The problem I am having is getting the data out of an array into each of the shared variables.  I don't see a way to load the value of a shared variable using the property node (so that I can do this inside a loop).  I also can't setup an alias that would access an array element.  I don't want to manually create 4000 variables.

Any ideas would be appreciated.  Thanks.

I have never had to resort to creating Shared variables programatically so I will leave that for others.

I would cheat.

In LV 7.1 DSC i could import my tag config from a csv file. After importing and saving in LV 7.1 I could let LV create the SV's when the code is updated.

THat all assumes I will only have to do that one.

I have used the interupts fired when SCRAMNet locations update to "steer" the value to appropriate code which could then in turn update the SV using a datasocket write since I can compose the URL for the SV dynamically.

Just sharing ideas,

Ben

How about setting up a Cluster that identifies the (String) Name, and (Numeric) Value, and then identify and Array of these Clusters ?

This Array then becomes the Shared Variable, and the 4000 pts of data are directed to the array, by index.
