Hello everyone, i am a university student at my final year and as a project i am trying to build a block diagram for getting some datas from an engine. But i am having problems communicating with AVL Digas 4000. Now i try their software IsoTec.exe and there is no problem getting datas with it. But when i try to get some data with labview these errors occur.
In the first picture when i try to connect Return count to Byte count there is no problem with getting data however the data i get is not enough to derive something from it. You can see the situation on the second picture. And after a while working like this i gives an error you can see it in the 3rd pic. After pressing run again it starts running again and begins giving random bits of the data you can see it in the 4th pic. But it is working, so i break the connection between Visa W and Visa R and connect 144 constant to Visa R byte count it gives much more info so i can derive something from it you can see it in the 5th pic. But after 4th or 5th time it gives an error again (6th pic) and this time it wont run again until i break the connection between the constant and reconnect the Visa W and Visa R. And then i run the vi like this a few times, break the connection again, connect the constant again to get some more useful data and then the same thing happens. I am not able to get a constant data flow without an error.
Can you please help me with this issue? Thank you very much in advance
