i cant configure my instrument IO assistant

[suanhadiah]

i interested to create the remote laboratory.
i want to controll the coupled tank apparatus pp-100
via internet using labview 7.1 with NI DAQ 6.9.3. but
i have some problems. the problems are

* what interface you use to represent the instrument
in the vi. is instrument I/O assistant?
if it's right i have a problem when i configure it.
when i selected the instrument then run, there's an
error message "the resource is valid but VISA cant
currently access it. VISA status code bfff0072" it
also happen when i tried to query and parse. i didnt
have the response data.

* when the labview is connected to the instrument, how
to broadcast to the internet. how create your PC
as a server. could you give me the step?? or you only use
the web publishing tool?

* could you tell me where can i get the PID
toolbox free.

thanks for your help.

regards

suan

The information you've provided is very confusing. You first say you want to use NI-DAQ and then in the second you talk about using the Instrument I/O Assistant. They are two completely different things. NI-DAQ is for pc data acquisition boards from NI. How is this "apparatus" connected to your computer? If it's serial or GPIB, then the Instrument I/O Assistant can be used. It kind of sounds like you might be attempting to use the assistant with a serial connection and that another program is running that also is using the serial port. If you have Hyperterminal or any other program talking to the instrument, you will have to close them first. Windows doesn't allow two different programs access to the same port.
