Shared Variable Data Integrity

[thad_tensentric]

I am using Network Shared Variables for a project and have a question about if there are any data integrity checks that are built into the NI-PSP protocol.

I'm more of a hardware engineer and I am just wondering if there is any way that data can be corrupted when using Network Shared Variables.  I could probably just cast the data to U8 and then CRC it on both ends, but wanted to check about integrity inherent to Labview for this.  Because we mainly develop medical devices, any Labview code needs to be validated if used for verification testing.

If there is NI documentation/studies on data integrity for this, I'd appreciate it if someone could point me to it.

Thanks!

Hi Thad,

The following article talks a little about data integrity when using shared variables.

I hope it helps.
