There are a few different methods for developing a LabVIEW application that can communicate to a Galil motor controller. Message 4 of 7. The applications engineers at measurement computing are very responsive to help requests. Having every case how you do now with no delay in the loop means you are running every one of those cases as fast as your program can. You then see the function name with the and a number appended.

Brandon, The input to the command node is a string. If you are getting multi-line responses, that would also account for your problem.
It would probably be valuable for you to spend some time going through the tutorials. I have no idea how this DLL was written and probably won’t be able to find out. So you may have solved your problem but may have introduced another less obvious problem instead if the DLL is not written for that. Thanks in advance for any help provided.
That does require to set the labvied path to the actual DLL though in order to work. The ggalil node should only be called once in an application.
Using LabVIEW with Galil Controllers | Galil
Oddly enough, with the error, the DLL routines still seem to do what’s being requested of them. You do not want to rely on the vagaries of software latency if there is any hint of a safety issue.
For example, as seen above, the sources text Exception occurred in Galil: Can you share any code to help give us more context? For the Galil side of things You don’t need to download your program to Galil every time, connect using Galiltools or GalilSuite and download then use the BP command to burn the program to memory.
Change the element to write and galjl address. Message 7 of 7. And, as I said before, you should also consider implementing a “dump buffer” subVI before any VI that makes a request for data to be returned.
Galil Motion Control
I’m guessing you are trying to use RS communications? Accepted by topic author WNM. Each call-library function returns the error but lanview I32 error number is always zero. Rolf Kalbermatter Averna BV. If a valid connection string is specified ex COM1the program will attempt this connection directly. Highlight the Galil Object, click OK.
Yes I am using serial connection to communicate, Thanks so much for the help, it is greatly appreciated.
Well if you can guarantee to call any and all DLL functions from within this single non-reentrant Action Engine, then you basically are already protecting the calls to the DLL from reentrant executation. Thank you for taking galill time to look over everything.
This may take a moment.
Motion Control and Motor Drives
I do this by writing a Movement command that responds a 0 or 1 accordingly. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.
Hello everyone, I am very new to LabView and to programming in general but I am trying to piece together a labvlew tensile bioreactor to test some bladder cells for my Galul research. I’ve attached an image of a dump-buffer routine that I had handy and it is similar to what you would need for a read-response routine. Here is the code. Message 7 of 7. I’ve looked all over the examples and forums and youtube tutorials and I’m just really having a hard time and this particular stage is taking too long.
Note that to run this VI in a useful manner, you will need to be able to communicate with a Galil motion controller over an Ethernet connection and that will, for the most part, limit this discussion to what the experts among you know to be happening under the hood of LabVIEW in situations like this.
That doesn’t make any sense unless the motor is just performing a loopback. IGalil to the “reference” terminal of the Invoke Node.
