LabVIEW
Keyence GT2-UB1 commands, driver or LabVIEW VI
Solved!
The Keyence website requires a registration to get at even the datasheet or user guide as far as I can see, so I don't want to access either of those things.
If you have access to that information, you may be able to find more details on possible commands that you can use to access or interact with this device. By your use of the term "command" and the 'm0', I'd guess perhaps you can communicate via some sort of message-based protocol, perhaps using the VISA nodes in LabVIEW?
Do you have any more information or documentation you can (legally) post?
Hi nrcan,
I tried to write a reply earlier with my phone but the internet connection was spotty and it failed to post. I confess to not wanting to try again!
Based on reading your post, I'd suggested that you might want to take a look at your VISA driver installation. Third-party drivers and applications often install a copy of the VISA library, and LabVIEW will typically not work with other companies' drivers for VISA. A knowledgebase article describing this in more detail can be found here: After Installing 3rd Party VISA Software NI VISA No Longer Works.
I struck through that because maybe it isn't related to your problem, but since it might be relevant/interesting I didn't delete it.
From the example, you can see the necessary connection parameters. What you need is just the list of commands, for which you probably need the company's help. Hopefully your rep's visit will be able to give you some reference manual to list these commands and their argument or return formats.
Keyence definitely does not install a VISA version of their own. While they are not exactly hostile to LabVIEW and NI products in general, they generally feel that it is more of a hassle than anything else to support that and that their own software is all a user ever should need 😁.
So it's a bit a hit and miss to get support from Keyence support to use their hardware with LabVIEW. If you are from a major account or do a project for an important account of Keyence you definitely get better support, with sales reps even willing to ask for help from the HQ in Japan.
The sample shows clearly that the device is simply a virtual COMM port and can be accessed with VISA. It is not that it can't be accessed with LabVIEW or other software, but simply that they do not want to document the commands that can be used. If I would have to use that I would install the trial software on another computer and then connect a software serial port monitor to it.
Thanks for the reply, Since my original post I have made many programs using these particular sensors they are truly amazing! better then our LVDT's, just rock solid linear response with nm resolution and um accuracy/repeatability. I can't say enough about how well they work. I have developed Vi's for both their USB devices as well as their Network adapters.(network more then 10 in use at one time) If your looking at these, the USB's have options that the Network adapter simple doesn't. such as Querying them to get there Model/serial and channel making programing easier. All that said. I don't know how to upload to ni, but am more then willing to give you my basic code. PS the core VI's came from the manufacture in Japan.
Thanks,
I take this opportunity to bounce on this discussion to ask you for help.
I ask for your help on the same problem on the Keyence drivers. I am on project in the framework of validation of the master which requires that I assemble a test bench for an acquisition multiphysics data among which: the moves of a system. On this, I want to use the sensor of LK-G3000 laser measuring moves. However, I installed a driver provided the Keyence, but I cannot find it in the Instrument I/O palette. can you help me with this problem or give me an alternative?
