Instrument connection via LAN.

Hi,


I am using the NI-VISA library in my project. I successfully installed it and have controlled the instrument using SCPI commands.

 

I have attached two codes for writing and reading voltage: one for connection via USB and the other for connection via LAN. The code for the USB connection runs properly.I can sent Write and Read command successfully. But, in the LAN connection code, I can successfully set (write) the voltage value on the instrument (Power Supply 750VA, SN: 802305113787030012), but it cannot read the value properly.

 

I don't know what the problem is. Please help me out.

 
Regards,
Pallavi Wagadre

Please provide both vi's, so we can see what could possibly be the problem.
