  1. I am creating a new DAQ system for my department, and we want the ability to use some files from our old DAQ system. However, I am unable to view the diagram of a certain VI we have that's rather important in the process so I can update it. However, the VI appears to be locked with no password. However, I can't simply click unlock as the whole window is "greyed" out. What can be done? Also note, I am using LabVIEW 5.0 on Solaris.
  2. Our department has decided to expand our DAQ system. We currently use KineticSystems V200 boards and DAQ Director to control our DAQ system. However, we are purchasing quite a few PXI-1045 Chasses and loading them up to expand our DAQ system. However, we still want to be able to use our Kinetics V200 boards, so we purchased a MXI-2 board and are able to connect. We are using Windows XP to communicate by the way. When we first put in the card and installed the KineticSystems drivers and VIs we were fine. I am able to take data and everything. However, once in a while, the V200 board will disappear from MAX when we run the Resource manager. Then sometimes it will think it's made by another manufacture (AMP, Inc.) then will disappear on the next run of Resource Manager. To bring the board back, the only way I have found to work is to manually power cycle our VXI crate for sometimes up to 30 minutes! This is DEFINITELY not going to cut it, especially since we will be using 3 fully loaded VXI crates. Does anyone else have any ideas why this could be happening or what I can do about this? Thanks, Michael
  3. QUOTE (Norm Kirchner @ Sep 3 2008, 10:31 AM) Actually, I believe I just found what I was looking for after making this topic (who wouldda thunk?). There is an invoke node that allows you to return an array of the hierarchy. I was looking in the wrong spot all along. Thanks, though.
  4. I'm trying to create a user interface for a data acquisition system I am working on. I thought a tree control would be the best way to visualize our DAQ system (see what crates belong to what computers and what cards belong to what crates). It is structured in this manner: - Blade 1 ---Crate 1 -----Slot 0 -----Slot 1 -----Slot 2 -----Slot 3 -----Slot 4 -----Slot 5 -----Slot 6 -----Slot 7 ---Crate 2 ---Crate 3 +Blade 2 +Blade 3 etc... I would really like to be able to select "Slot 4" From crate 1 in Blade 1 and have it return the string "Blade 1\Crate 1\Slot 4" I have been messing with property nodes for a couple days, but all I have been able to do was return "Slot 4" but none of the parents. How can this be done?
  5. I'm using an NI PXI-1045 chassis connecting through a MXI-4 card to my computer (Running Red Hat 3). I can see all the cards with nipxiconfig. What I want to do is take samples from an NI 4070 DMM. However, when I try to intialize it with the name "PXI8::13::INSTR" (What shows in nipxiconfig for the 4070), I get a VISA error that states that "the given session or object reference does not support this operation". Please help!
