I am stuck with a problem with the crio communicating through the serial port to an Alicat flow controller.
It was working before Christmas and haven't been back since. Got here today and tried to run it and it would not run. Verified wiring and then used a serial to usb connector to my pc to verify through simply modbus that it works and the wiring and the alicat are working fine. So I tried to download the ni-visa incase it was bad but once I got it downloaded it goes to installer and shows no action.
The controller should be outputting the info but I just cannot get it to read. When I go to shutdown the program using the stop button it says timeout.
I'm really at a loss why it worked and now it doesn't? Any ideas on what it could be?
