LV7 to LV5.1 vi conversion, must I upgrade my old version of LV5.1?

[ctanner]

I have some vis that I believe are created in Labview 7 that i would like to open and look at. However I  dont use labview a great deal and so only have an old version (LV5.1).  Is my only option to buy an upgrade to LV7 so I can open the vis? Is there another piece of software out there that can do this for me?

Certain functions that are in  LV 7 were not present on LV 5.1.

so if this code which u want to convert to LV 5.1 has any such functions, there is no use of converting it to the lower version.

So u decide if u wanna go for an upgrade

Hello,

you can try to downconvert from LV7.0 --> LV6.1 --> LV6.0 --> LV 5.1 with the "Save with Options" --> "Save for Previous" function. But it is not sure, if you can open the downconverted VIs without errors in LV5.1 because in LV7.0 there are a lot of new features which could not be used in LV5.1. Try and find out!

I think this is the only way to see the Block Diagramm in LV5.1.

Thanks for the replies .....

Problem is I dont have LV7 to be able to do the back conversion of the LV7 vis to my LV5.1 version of Labview. Woah ive just been told that the latest version of LV is 8!! blimey I am really behind the times! So I guess the vis may even be LV8. I have tried to open the vis in LV5.1 and they wont open so I guess you are correct about new features not being back compatible.

To be honest I am not too bothered if the vis wont run on my LV5.1, but if i could get them opened up I would like to get to the front panel and block diagram to be able to see what is in them. They are for a specific high speed serial card and within the vis I should be able to glean how the card is commanded and telemetry received. Unless of course the block diagrams are not accessible, but then that would be another issue.

Try to post your VIs in this forum, perhaps anybody could downconvert the VIs.

Or if this is not possible someone could open the VIs and make you pictures of the block diagramm and the front panel.

Would like to second Thomas's suggestion

Ok great. As theres a library with the two main vis i would guess that theres sub vis within the two main ones, and its probably going to be the sub vis that do the nitty-gritty stuff i want to get at (comms with the serial card). Not sure how many in the lib but i think theres a few, guess it may take somebody a while to convert, but it would be much appreciated.

Best regards

Please attach the .dll that goes with these files. All this code is really doing is interfacing with the dll that they have developed. Post the dll and I will downconvert it to 7.0 and someone else can take it from there. or another thing you could do is download the trial version of LV 8 and look at the code yourself. I think you would get more out of this and you could see if LV 8 is worth the upgrade to you.

Ok, .dll as requested. had to zip it as it wouldnt let me post othersize

Can i download the trial LV8 from the NI site, if so i will have a go at that. i know LV is the future so i need to push to buy the new version (we still use VEE and i believe is soon to be no more. thanks for your help
