  1. Press release yesterday. http://www.microsoft.com/presspass/press/2...vailablePR.mspx
  2. I was watching Stunt Junkies on the Discover channel last night and saw a Wind Tunnel Testing site run with LabVIEW software. The episode is called "speed skateboarder" where Michael sherlock tries to become the first skateboarder to go 100mph....The show deals with mitigating risks of performing the stunt, then the stunt itself.... They had a good 3-4 minutes during the wind tunnel testing and showed labview FP VI's numerous times....=) For those interested in seeing this episode...it'll be shown Feb 22nd on Discover Channel....
  3. Instead of using a case structure for acquire the data, try using a while loop with the "Read" Switch connected to break the while loop. That way you get more than 1 data point.....Attachment to follow PS. Just attached to show how looping will get you more than 1 data point (until you switch "READ" to off.)

  4. I'm currently using the Dell 2405FPW monitor and its beautiful. I can only imagine a 30" screen...java script:emoticon(' ', 'smid_29')
  5. can you post the VI that you're using to read the multimeter? Sometimes Tabs, Linefeed, or Carriage Return characters are used to separate data points....not sure in your case...it might be in the MM manual though... Regis
  6. I'm still having problems grasping the concept of Setting a value to a specific Attribute ID. The Device I have is an encoder wheel that will determine the distance traveled and speed of a web converting machine. Every so often, I'd like to "reset" the distance traveled after a run is complete. Basically, the logic is to SET the position value (attribute ID =10) to 0. I can Read the position value (attribute ID =12) and velocity (attribute ID=22) but haven't quite gotten how to Write a value.... Here are some more specific questions: 1a) Do I need to create another OPC DevicenetExplic
  7. I received a reply from NI and posted the message below. It seems like I was expecting the Attribute to be clearly "visible" in the buffer of the encoder. Nowhere was it mentioned that In order to read an explicit attribute item, you have to first "WRITE" to the encoder, the attribute ID. This will populate the buffer with the data corresponding to that item. Then perform a "READ" from the encoder of the correct data type. this will return to you the correct value. Here are some other questions I have: 1) if I wanted to read a bunch of Attributes, would the have to perform a set of
  8. Khalid, Thanks for the suggestions. I tried using the IID ( Instance ID).USINT (Attribute ID -1) but to no avail. It's not that i don't get any data, it's just that the data received does mean anything. As a number, or Hex, or any combination thereof. I did modify the NI Labview DNET example (GetIdentityAttrs.vi) to get the data i'm looking for; position and velocity. The parameters are such. MAC ID = 32 (allen bradley Slave device) Service Code = 14 (Get) Class Code = 2F (47) - Encoder Instance ID = 1 Attribute ID = 12 (position) = UDINT data type Attribute ID = 22 (Velocity
  9. I'm trying to set up an Allen Bradley 842D Devicenet Absolute Encoder using the OPC server. To start, I verified that the device and network is functioning properly. The manuals for the device mention that the data can be retrieved from the various Attribute ID's in each class. For example , In Class 1, you can retrieve Vendor ID (Attribute 1), Device Type (Attribute 2), Serial Number (Attribute 4) etc.... From the OPC Server Help example below, it starts to describe the location of the data desired, but fails to show me where I specify the attribute ID. For example, lets say in the
  10. although its not the cheapest alternative, if you don't want to use an OPC server, than NI Fieldpoint units would allow you to do exactly what you want (if you didn't know about this already).... Regis
  11. Have you looked into using the VI Server features in Labview? Also check the examples (search under "server") provided with Labview. Regis
  12. Have you looked into using datasockets and "publishing" your data from your RT units? Depending on how much stuff you're looking at, this could be quick enough for you. Also, using an OPC server is pretty much the same idea as above....ie. having a global repository for data.... In these cases, you'd build your own HMI that would "link" to the Datasocket item (subscribe) or OPC tag. You could then control this vi via a web browser using LV's pre-installed web server....

  13. You win a free copy of Microsoft Paint! (pre-installed on your Windows PC) :thumbup:
  14. You can check out the frequent updates here: http://www.grandchallenge.org/ Here's an article from news.com that mentions the Virginia Tech team (shown at NI WEEK 2005). It mentions: That Virginia Tech team differs from most others in the competition because it's largely made up of mechanical engineering majors, as opposed to computer science students. The team built Rocky largely with a graphics program, using visual graphs, as opposed to writing lines of code, team members said. Hmmm...i wonder what "graphics" program they use?
  15. Just for clarification, Responses to my questions by the NI presenter are shown after the "A)"
