Operating under the assumption that by "reset" you mean to reinitialize the connection to the VISA device... Using the current architecture, I would add a new event case that closes the current connection and reinitializes it. See attached.

 

This can be done a bit more cleanly with a state machine that has "initialize" and "close" cases.

 

**EDIT** It's very important that you replace the VISA session tunnels on the while loop with a shift register. I've updated the file to reflect this.

 

**EDIT 2** Looks like the "format string" function which formed the string to close the connection was wired to the "initial string" node instead of the "format string" node. I have fixed this and updated the vi again.

I took a closer look at your string formatting and it occurred to me that there's a bit more in there that needs to be. Assuming the string you want to have at the end is "AMPR -110.000000", all you need to have in the format string is "AMPR %f"

 

See the attached snippet for a comparison.

I have started using "%#g" for my SCPI drivers.  Adding that '#' in the middle tells the formatter to drop off any trailing 0s.
