gpib?

[miki-avi]

I am using CWGPIB componnet, can I use it to work as NON CONTROLLER device ? What shoul I do?

Can I set, IBSTA word to end I/O (CMPL &H100) ?
I am sending ibwrt command to the device and the status word remain 144 hex, how can I set it to be 100 H again ?
I have a loop that check IBSTA :
while (ibsta% and LACS) {
ibrd(GPIB_BD%,buff)
Execute somthing (buff)
...
...
}
Thanks

There are several documents and example programs on-line at National Instruments that show how to use a NI-GPIB as a non-controller. Here are a few documents and examples that I found by searching for "+gpib +non-controller".

I hope this helps out.

Thanks,

O.K, now I am using it as non-controller, manualy I can write and read to the GPIB bus, but how can I obtain a loop that monitor IBSTA? , in order to know who tallk and who is listen.
The situation is, evry time that, the controller write/read to the bus, I detect status word as talker/listener ,while finishing, performing some tasks my loop should be continue capture another event, but ibsta should be reset first (otherwise I will get into infinity loop) .
There is a command that I can reset ibsta to his defult value? , in order to notify again who's tallk or listen?
Be aware that I am a non controller, and I do have access only to the non-controller

Thanks Avi

From your programming, it appears that you are using Visual Basic. Is this a requirement? National Instruments offers NI-Device, which is a C++ driver for programming a non-controller.
