I would like to develop a diagnostic application in which a laptop computer
is attached to an existing GPIB network on a tool. Depending upon GPIB
events, I would like the diagnostic computer to trigger certain DAQ events.
For example, if the main computer tells a DMM to read a voltage, I would
like the diagnostic computer to recognize the GPIB command and independently
measure the voltage and several I/O states (with a separate DAQ card). There
are multiple GPIB devices and multiple modes for these devices (e.g. single
triggered acquisition for the DMM, averaging, etc.).
The GPIB analyzer software from NI looks like it performs some of what I
need. It would allow me to monitor the bus traffic, know what device was
addressed, and the command
sent to it. Unfortunately, that's all it will do.
There is no API available to tap into this functionality and be able to use
the events detected to trigger DAQ on another card.
Does anyone know of a solution for this application? A LabVIEW/NI solution
is preferred, but I can consider other possibilities. The diagnostic
application should not require any re-programming of the SW on the main
computer.
Thank you,
