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. Message 4 of 7. Message 3 of 7. In the image above, the “Error Out. Yes I am using serial connection to communicate, Thanks so much for the help, it is greatly appreciated. Message 1 of 5. There are more errors that are not defined here but the source text will help determine the error response from Galil.

Just please don’t call it an ESD button, since it isn’t.

Message 2 of 7. If the bogus wait time is too short, then the indicators are not synchronized with the program state or in this case, with each other. It sort of looks to me like there may be a problem with the library.

Labview | Galil

It opens an Ethernet connection to a Galil motion controller, optionally asks it for the value of its internal clock and then closes the connection. The people who supplied the library also provided some instructions on how to generate the LabVIEW interface VIs using the import wizard and in those instructions they said to leave it set to the “Run in UI thread” default setting and I did not have the knowledge to question that.

Skip to main content. Message 8 of The address node should only be called once in an application.


Add a string constant that has the program:. This will sometimes get fixed when I use the show highlight button on the Vi. I am trying to wait for the: What I do have working in my favor is that I’m using a single non-rentrant VI as an “action engine” interface to the the DLL so that it will enforce serialization of any and all calls to the DLL’s various functions.

Thank you for taking the time to look over everything. Now the problem I am having is that the second time through the for loop only one command is being sent which in case should respond “: Message 4 of I am aware that Galil can burn the program in.

One thing else that did work was connecting a “probe” to any data path on the input side of the conditional frame. It would probably be valuable for you to spend some time going through the tutorials.

Using Labview with the GalilTools Communication Library | Galil

If you want to send a stop, create a node with the string input as “ST”. There are a few different methods for developing a LabVIEW application that can communicate to a Galil motor controller.

I already have the VI written to control direction and step conditions but don’t really know how to make it communicate to the motor through the galil stuff. A DLL needs to have gaoil programmed for full reentrant execution in order for the Call Library node to be allowed to change to “run in any thread”.


Message 4 of 7.

Motion Control and Motor Drives

Does any of this make sense? I am struggling with which structures should be used.

You wil be able to see the different functions and methods that are being called into and what the expected input and return albview are. Update of front-panel indicators is lagging when testing functions in vendor-supplied DLL Solved! I have no idea how this DLL was written and probably won’t be able to find out. I learned something today.

National Instruments 1 Test is worth expert opinions. Do they need to run in the UI thread? The Galil is for the most part a synchronous system where you send a message and you get a response gaoil there it also has the ability to send unrequested asynchronous messages if something happens that it thinks you need to know about.

This is followed by either a command to send the motor to a homing position or to step to a certain angle. I am using a thin beam load cell to feedback through LV to control the motion of a Hyadon Linear actuator stepper motor.
