calling a vi multiple times makes the timer "crash"

[henk007]

I use a subvi for writing data from a profibusnetwork. In this vi I can set a timer for the "update" to write away the data. I use a global variable to remember the last time the writing was done. The problem I encounter here is that when I use this subvi multiple times only the data I want updated fastest will be written away.. My question is: Is it possible to use just this one vi multiple times instead of renaming it for every datasource I want to write away?

Thx in advance,

Under VI properties-Execution. Select Reentrant Execution. You may have to change the global variable and use something like a uninitialized shift register to remember the previous number.

Use a while loop with an uninitialised shift register instead of a global,
and build it into a function marked "re-entrant". This way different data
exists in each different copy of it in the code.
