I am very new to LabVIEW, and I need to be able to control and generate a 0-10 Volt signal with my SCB-68 and the DAQ software. I've wired my output to AO 0 and AO GRND, but how do I program the LabVIEW code so I can enter in a value between 0-10 and have the SCB 68 generate that voltage? I know that the max output from the SCB-68 is also 5+ volts.
You will first have to get a DAQ card since the SCB-68 is nothing more than a dumb terminal block. There is no max voltage out from the SCB-68. The DAQ card you use (whatever that might be), will have a maximum voltage.
When you get the card, go through the tutorials at the Getting Started with DAQmx page. Then open the Example Finder in LabVIEW and expand Hardware Input & Output>DAQmx>Analog Generation>Voltage and look at the VIs there.
I just have installed PCIe-6353 DAQ card. I also have hooked up a chassis SCXI-1000 (having strain gauge module SCXI-1520 and thermocouple module SCXI-1102) on Connector 0 and on Connector 1, I have hooked up SCB-68 terminal block! I am trying to generate an AO voltage of 5V to control the speed of a motor. I am hooking up wires from DAC0 OUT and AOGND terminals of this SCB-68 termianl block and then connecting them to the controller of motor. The only issue with this set up is that I am not able to get this voltage generated out to these terminals! All other signals are working fine!
Please help me as this is my fisrt experience with this PCIe-6353!! Do I need to do something in Measurement and Automation Explorer (MAX)? I am also pasting pictures of how I have configured my hardware set up in MAX.
Thanking you all in advance!
All the SCXI information is irrelevant since that is connector 0.
The most relevant information is missing. What is your code to generate a signal and what analog output pin are you specifying? If you disconnect the motor and just probe the SCB-68 pin, do you see a voltage? Have you tried to generate a voltage with the test panel in MAX?
What channel on your PCIe-6353 are you attempting to generate with? If your SCB-68 is attached to connector 1, then you'll need to generate on either AO2 or AO3. I will assume that DAC0 OUT corresponds to pin 22. This pin is connected to AO 2 on your PCIe-6353.
Hope this helps,
Thank you very much for everyone! Special thanks to Mcdan!! It is working now!
Well! The trick is in choosing correct Physical Channel in Labview and quick reference labels for SCB-68 pinout when it is hooked up on connector 1 of PCIe-6353 for AO generation. Since PCIe-6353 has two connectors (68 pins) and can generate 4 AO, where Channel:AO0 and Channel:AO1 (in Labview) can be used for AO generation when SCB-68 is hooked up on connector 0 and Channel:AO2 and Channel:AO3 (in Labview) can be used to generate AO when SCB-68 is hooked up on connector 1 on same pins 21 & 22 of SCB-68. I was tricked by the quick reference labels for SCB-68 E-series which I was using for my application and was working fine with PCI-6254 on connector 1. Since PCIe-6353 is having additional feature of AO in comparison to PCI-6254, the quick reference label layout of E-series does not explain the correct titles of AO pinouts for the PCIe-6353. Below is the link where I took this quick reference!
Thanks to all again!
