FUNCTIONS
Main Principle
The idea behind functions is to create a set of rules by combining different operations for various
channels or elements. This set of rules is evaluated to a logical true (1) or false (0) result. Function
then can be used to turn, for example, Power Output on or off. Quick example could be turning the
secondary fuel pump on if a fault is detected on the primary one.
Operations
Following operations are available to use in functions:
Test Operations
Is True Returns true (1) if channel is true (its value is other than 0)
Is False Returns false (0) if channel is false (its value is equal to 0)
Comparison Operations
Equal Returns 1 if Channel is equal to Constant
Not Equal Returns 1 if Channel is not equal to Constant
Less Returns 1 if Channel is less than Constant
Less or Equal Returns 1 if Channel is less or equal to Constant
Greater Returns 1 if Channel is greater than Constant
Greater or Equal Returns 1 if Channel is greater than or equal to Constant
Logical Operations
And Returns 1 if both Channel #1 and Channel #2 are true
Or Returns 1 if either Channel #1 or Channel #2 or both are true
Xor (Exclusive Or) Returns 1 if either Channel #1 or Channel #2 are true, but not both
at the same time
Pulse Generation Operations
Flash Flash is triggered by Channel and returns 1 for the time specified in
Time On and 0 for the time specified in Time Off as long as
Channel is in High State. If Low State is detected, Flash will
imediately turn off.
Pulse Pulse switches between 1 for the time specified in Time On and 0
for the time specified in Time Off for the amount of times specified
in Count. It can be set to trigger by Rising Edge or Falling Edge.
Pulse will still continue for Count number of times even if Channels
signal is lost. Pulse will also ignore any Channel input until Count is
reached.
If Time On is set to 0, Pulse will generate a short impulse.
