Hi all,
I'v got a question concerning the USB-6501, USB to Parallel interface.
In our production area we've got four boxes with different testequipment in them. In each box a USB-6501
is installed to control the interfacing. A Labview program is then installed on multiply testpc's, to
control the four boxes.
When i, for the first time, connect a USB-6501 device to one of the testpc's i can, in Measurement and
Automation studio, see that the device is given the handle "Dev1". As it is now, i then create a "task" from this device handle, which i'm then using for controlling the device from Labview.
My problem is that when i now disconnect the USB-6501 device and connect one of the other boxes, with a
different USB-6501 interface, this device is then given the handle "Dev2". Now i would have to go and
change the task i created ealier, for my Labview program to work. The old device would still be
recognized as Dev1 if i would reconnect it again, and i would have to change the task again. With four boxes this would be quite a hassle, and downright unaceptable for our production.
If i could have it as i wanted, i would want my Labview program to create the "Task" on-the-fly, everytime i run the program. This routine would then search for any connected USB-6501 devices and create the task from this. In this way i would also be independent of having to create a task, when i need to create a new testpc, which is most desirable.
Does anyone out there have a solution for my problem?
Thank you all in advance,
