This engine is a timer that runs for a pre-set amount of time and then stops. By default, the
timeIn input is connected to the
realTime global field. It can, however, by connected to any other time source.
The timer
is started when the
trigger input is touched. It then runs for the specified
duration, and updates the
timeOut output with the time that has elapsed. During that time, the
ramp output is also updated. The
ramp output starts at 0.0
at the beginning of the cycle, and linearly increases until it reaches 1.0 at the end of the cycle.
You can disable the timer by setting the
disable input to TRUE. The output value remains 0.0 while the timer
is disabled. If the timer is disabled in the middle of a cycle the output values will be set to 0.0.
The
flags input contains control flags. Using the flags you can set the timer to be retriggerable in the
middle of a cycle, and set the output values to stay high after the cycle has been completed. By default, these flags are not set.
