When using a function to turn an output on in addition to having PWM variable mapping will the output come on, but obey the duty cycle rules set in the variable mapping? Or is it one or the other?
For example: I have cooling fans that will use PWM to control fan speed based on engine temp which is being reported over CAN. That's easy enough and I have the variable mappings set up.
But I am unclear how a function comes in to play. If I wire up a ground switch to input 3 and then create a function on that states "If input 3 status is True" on the fan output will the output come on and obey the temp rules or will it just come on at 100% duty cycle? Also will it obey the soft start rules?
Hopefully the pictures will help with my explanation
Hi Raymond, The output function will determine if the output is enabled or not, and then the PWM mapping will act on that output when it is enabled.
