Solved!
Go to solution

Can the PXI PROFIBUS Interface Module emulate multiple slaves at once or can it only emulate one slave?

Hey James, I just happened to be browsing and saw this. 

One slave at a time.

If I remember correctly, you can download a new configuration set up to the PXI card to change the parameters of the slave it's emulating, but this takes a few seconds (~10).

a_cluker,

 

Do you happen to have documentation about this?  I'd like to read more into it.

 

Thanks.

Hi Jenkins,

 

This was from an old issue I worked on. After some digging I found the code - it's not the prettiest - but it shows the basics. Essentially you're just modifying the address field of the slave blob.

In the project I used a cRIO PB as the master, so you might see some broken items if you don't have that driver installed. You can ignore that (as it was just the master I used) and focus on the PXI-PCI Slave Main.vi. If I remember correctly, the code was last saved in LabVIEW 2013 SP1.
