Problem !! while using event structure with VISA

I have attached the VI which is saved at version 2015

The ST[1] is your Stop command ... If it's supposed to be mirrored as acknowledgement you need to read that when you send the command.

Also, if you set the Booleans to Latch you can remove the Locals.

The point of having the commands end with semicolon is that you (probably) can write them together, so you can start the system by sending UM=5;MO=1;PR=23454; in one fell swoop.

It does not only return the ST[1]; many time it also returns BG; as well,

So I am confused why it returns commands when I call profiler position first time.

when I press second time it works in a way it should work and return me profiler position.

Because you (probably) sent those other commands before trying to request the current position?

And because you forgot to implement the communication protocal as described in the manual by not just sending commands, but also reading (all) their responses!?
