I have attached the datasheet of a Delta Oven.
I want to be able to read the temperature at all times using LabView and I guess NI-Visa is not possible with DAQ.
Also what command from the datasheet is used for DWELL Time(like staying at the set temperature for x amount of time)??
Commands are on page 51 Table 5-3
Solved! Go to Solution.

Hi Netsballer,
I want to be able to read the temperature at all times using LabView
Use VISA functions after connecting that oven with your computer.
I guess NI-Visa is not possible with DAQ.
VISA is something different than DAQmx…
what command from the datasheet is used for DWELL Time(like staying at the set temperature for x amount of time)?? Commands are on page 51 Table 5-3
Do you see the word "dwell" mentioned somewhere in this table? I don't…
So why do you think that device even supports something like a dwell time (by remote command)?
Btw. did you read chapter 5.8?

Thank you for the response.
I read 5-8. DUTYCYCLE?
Also if there is no command for DWELL Time. Can it be implemented using LabVIEW. Like a Temperature being set to 50°C then wait 10 minutes and ramp down to -10°C for 10 minutes. And repeat this cycle for 5 cycles?
Also can DAQ be used with this GPIB device?
If not how can I display the temperature from the oven in LabVIEW?
Thanks.

Hi netsballer,

It seems you didn't read chapter 5.8:
So you can command a setpoint and a time to hold that setpoint. You also can command the rate at which the temperature should change.
What else do you need?
Like a Temperature being set to 50°C then wait 10 minutes and ramp down to -10°C for 10 minutes. And repeat this cycle for 5 cycles?
Read chapter 5.8 again…
Also can DAQ be used with this GPIB device?
You can use your own sensors and attach them to a DAQmx device of your choice, but they aren't connected to that oven. GPIB is just a communication bus, but no "DAQ device" (in the sense of being supported by DAQmx)!
how can I display the temperature from the oven in LabVIEW?
Read the temperature from the oven using VISA. It has some commands just for that purpose!
Why do I need to read that manual for you? Why don't you read the manual on your own?

Thank you for the response its been really helpful.
And yes I had just realized what 5.8 was used for before your last response.
One last thing.
I want a button to be used for "write buffer", so I can attach multiple commands with each different button. any ideas?

Hi Netsballer,

Just place that button on your frontpanel!
(Does your device accept multiple commands in one command string? Otherwise just send each command on its own - loops are your friend here!)

Thanks.
Something like the attached picture?

Maybe...
Why do those buttons have no label?
Why don't you connect those LED indicators directly to the buttons?
Why don't you build an array from your buttons and use BooleanArrayToNumber?
Do you really need 4 case structures for such a simple input?

LOL Thanks again..

Just thought of one more thing.
Do I have to keep looping/calling the Temperature? command over and over to get constant temperature for my program?
Thanks.
