usb 6002 practice

[ceilingwalker]

I am testing it now. I am not exactly sure how to use the hardware and software for this USB6002 and LabVIEW. I wired AO GND to AI GND, and wired AO0 to AI0. I am using Measurement and Automation Explorer along with a multimeter to see what voltage is being output and from what I have so far, the answer is yes. I am reading on AI0 what my multimeter is reading.

I have done nothing with scaling, so far. I will be using 200 VDC, when I actually put this in circuit but will cross that bridge when I get to it. For now, no scaling.

This is very impressive s-ware! The huge difference to what I am experienced with (Allen-Bradley, Siemmens, DirectLogix, etc....) is speed! Just thought I would throw that in here. 🙂

I'm sure NI would love to hear that feedback.  Setting up scales in MAX isn't too difficult.  You have various options for using a table, or a polynomial, and a few others.  You then save the settings in MAX and you can call them and use them in LabVIEW.  You then read your channel and it returns the engineering units you applied to it.  You can also programatically create the scales using DAQmx VIs, but in my opinion it is better to have it in MAX.  It adds a layer of obstraction that is nice to where my software doesn't care about the scale or how it is made, it just uses it.  No need to re-invent the wheel if there is software that handles scaling for you.

Just need to figure out how to establish serial connection with HP LCR Meter and I am in business. Pretty sure that DAQ Assistant can't be used, as it is not showing my COM3 connection. Probably need the VISA for this however, that's my next task. Thanks for your support.

It sounds like you are making some good progress, but let me suggest you open the Example Finder by going to Help >> Find Examples.  There search for Serial.  The example I'm thinking of is called Simple Serial.  It shows how to open, write, wait, and read some arbitrary data.  It has some functionality similar to hyperterminal.  There are more advanced features like Asyncronous vs Syncronous, and terminating characters but it is a good start, and it should list the COM ports that Windows sees.

You can use the simple example but you can also check to see if there is existing code for your instrument. Simply use Help> Find Instrument Drivers. If one exists, there is normally an example of how to use it.

Tried that for the first time, just now. This software keeps impressing me more-and-more, with each new thing I learn. I took the Core I and started Core 2, online training. This is the most intuitive, easy to learn, controls and automation software I have ever used. Thank you

Fixed that for you.

Thank you for correcting me.
