7.4.3 Wind Vector Processing Instruction
The Wind Vector output instruction is used to process and store mean wind
speed, unit vector mean wind direction, and Standard Deviation of the wind
direction (optional) using the measured wind speed and direction samples.
7.4.4 Example Programs
The following programs measure the Wind Monitor 05103 every 5 seconds,
and store mean wind speed, unit vector mean direction, and standard deviation
of the direction every 60 minutes. Wiring for the examples is given in TABLE
7-4.
