[How to control Solenoid valves with TC-32 in labVIEW]

Hello @Vishank Battar.

To send a digital output signal from a TC-32, take a look at the 'Generate Values.llb' file, in the '\National Instruments\LabVIEW {version}\examples\ULx\Digital' folder, which is included with MCC's ULx for NI LabVIEW installation.

Select the 'ULx Write Dig Chan.vi' example.

 

When the example opens, you will need to change the 'Lines' field in the Channel Parameters.  Click on the down menu arrow and select 'Browse'.

 

Referencing MCC's Universal Library (UL) Help file (https://www.mccdaq.com/pdfs/manuals/Mcculw_WebHelp/ULStart.htm), it shows the TC-32's Port I/O with the output PortNum to be 'FIRSTPORTB', but a PortType of 'FIRSTPORTA' for Bit I/O.  If the list of channel options in the example only show 'Dev0/1stPortA/...', then the supported 32 digital output bits range from bits 8 thru 39, with 8 being digital output bit 0.  However, if the channel options show both 'Dev0/1stPortA/...' and 'Dev0/1stPortB/...', then 'Dev0/1stPortB/Do0' is digital output 0.  

 

Table 21 in the TC-32 User's Guide (https://www.mccdaq.com/pdfs/manuals/TC-32.pdf) shows pin 1 as digital output 0 (DOUT0).

 

With this example, you will need to remove the additional bit elements to test just the digital output 0 channel.

 

With regards to controlling a solenoid using a digital output channel, please reference the 'Digital Outputs/Temperature Alarms' section beginning on page 14 of the TC-32 User's Guide.  Take a look at Figure 7 which shows an example of controlling a relay.

I am running into this error. How do you suggest I go around this?

[How to control Solenoid valves with TC-32 in labVIEW]

Hello,

I would like to use my TC-32 board to send digital outputs to a solid state relay rack to actuate a solenoid valve. However, I don't know how to send digital outputs from the TC-32 board, and I can't find useful blocks in the MCC user library in LabVIEW for controlling digital outputs. Does anybody know how to send digital outputs from the TC-32 board, or has anybody controlled solenoid valves with the TC-32 before?

 

Thank you.

[ULx with windows 11]

Is ULx functional on windows 11? I was doing work on a windows 10 machine and transitioned to a windows 11 machine, and now I can't see the ULx for NI Labview library in Labview. Is ULx only compatible with windows 10? I see this on the instcal readme file after installation, so I think I need to downgrade my machine to windows 10:

 

Any thoughts?

 

Thank you.

[Can't create virtual channel with Labview VI]

I am getting the following errors when I try to create a Labview VI. What can I do to solve this issue?

 

Thank you.

[Is hardware required to start creating VI]

Hello,

I've ordered a TC-32 and USB 2637 board and I am currently away from my lab where the parts have been delivered to. Is it possible to work on the DAQ software without the hardware? I want to make a configuration file that has my boards and all of the thermocouples and pressure transducers that I will connect to the boards. Is it possible to do this remotely? Or do I need to have the hardware with me?

 

Thank you.
