How can I open/close COM port for IC-3120?

Solved!
Go to solution

I want to connect a sensor with Industrial Controller(IC)-3120 product through RS232 communication.

 

There exist some basic VI examples for serial communication for LabVIEW and most of them use VISA to configure, read/write and close the serial port.

 

What I want to know is that should I also use VISA in order to open and close the serial port for IC-3120 product? or should I use different way?

 

Sincererly,

Short answer, use VISA. It is the recommended API for communicating with a number of interfaces, including serial. The fact that you are using an Industrial Controller does not change that. The shipping LabVIEW examples are a good starting point.

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,
