I interface to a wind instrument that measures wind speed and direction. It outputs a reading every second on a RS-232 port. The wind instrument connects to a PC where proprietary software displays this info graphically.
Log files are created on the PC. So far so good. What I now need to do is to access the real time data so I can display it in my HMI. How do you suggest I go about this? Can the contents of the COM port used somehow be echoed? All suggestions welcomed.
