Also you said you just bought the LSP-500VAR. Did you get it new, or is it a used instrument?

i am attaching the snapshot of my block diagram, i have my string changed to hexadecimal format.

It uses modbus? Where did you get that code? Have you tried the library from NI?

I just got the module from one of my friend who was working on modbus earlier. I dont think he used Ni lib but made it him self. The model 2 shows the block diagram for the same.

[Dennis_Knutson]

Definitely try the library from NI.
