How can I open/close (serial) com port in LabVIEW for IC-3120?

Solved!
Go to solution

Hello,

 

I want to get data from sensor to Industrial Controller(IC)-3120 product through RS232 communication.

 

In some basic serial examples of LabVIEW (e.g. Simple Serial.vi), most of them use VISA to configure, read/write, close the COM port.

 

What I want to know is how should I make a VI so that I can open & close the COM port and read the data package from the sensor using IC-3120.

 

Can I just use VISA as example VIs? or should I do some different way?

 

Best regards,

What have you tried? What didn't work? The serial port on the IC-3120 is standard present as VISA resources, so your questions make me assume that its a presales question or you have not bothered to try it yet? For a presales question you would however be fairly late as it is a mature product whose final order date is December 30, 2022.

Hello,

 

I sincerely appreciate for your earnest answer.

 

It was the very first time that I tried to use RS232 communication with IC-3120 product.

 

So I was wonder if there is specific way to use serial communication with that product.

 

Thanks to your advice, I could make VI for obtaining sensor data with IC-3120.

 

Again, I appreciate for your great help, and I hope wonderful events are waiting for you and your family in this new year.

 

Happy new year!

 

Best regards,
