What exactly are you using for the logical name? You've got a coercion dot on the input of the initialize function which makes me think you've got an incorrect control. Just right click on the input and select 'Create Control'. Since you are not using the IVI class driver, you should be specifying the specific logical name. It does not make much sense to me to use IVI unless you are using the class drivers. The one exception would be if the only driver available is IVI as is the case for this.

then what should be the logocal name for this? initially i put GPIB0::18::INSTR, same as whats indicated in ni max.

[Dennis_Knutson]

Yes but I think you might be using the incorrect class for the logical name. That's what I mean about the coercion dot on the input to your initialize function. Did you create the control by right clicking on the initialize function or did you create the control on the front panel from the I/O palette?

[cmdrb]

I create the control by right clicking the initilize function. but its initially blank, i tried to refresh it, but its still blank.

that why i tried it on name same as in ni max, (thats the time the coercion dot appear) but it didnt work .

I think i need to install some drivers for this? right?

whats driver should i need to install?

here's the installed driver in my system:

agesa (installed from ni)

agilentsa ivi-com driver 4.0.0.3

[Dennis_Knutson]

Aside from the instrument driver and the IVI compliance package. I think that is all you need to install. If the instrument is not selectable in the control, it might be because it hasn't been specified in MAX as the driver for the class.

hi dennis,

i already configured it and i got the list of driver/logical names already.

but i still got some errors. please see attached file.

can you help me on what should be the data in driver session?

[Dennis_Knutson]

I'm trying to rely on memory since I don't have any IVI drivers installed or any real instruments. I thought it was supposed to be the Instrument Driver Software Module instead of a Logical Name. I hope someone who is currently using an IVI driver can provide more accurate information.
