How can I connect HOST PC COM port under cRIO 9074?

[sad0000]

I can't find any HOST PC COM port on my cRIO.

I tried to use global variable but it was unuseful.  Is there any solution?

And why should it?  A cRIO is really another computer.  Would you expect your PC to see the serial ports of another PC on your network?  No, you wouldn't.

If you really want the cRIO to do communications of some sort over the serial port of the PC, then you will need to make an application on the PC that can communicate with the cRIO, typically over TCP/IP or Network Streams.

thank you for your reply. I will try your solutions.

Here is my project. Detect one direction force value and control a motor. I chose scan mode to detect my sensor. I must put the program under cRIO to make sure the value is correct. If the program is under cRIO, it cannot connect my PC port so that I cannot send any request to my control board 

I tried VISA server but it cannot work
