Timer
A Timer object can be used to start an action after another one has occurred, with a delay
time. It is also possible to send out a value cyclically. In the latter case, a value will be sent
each time the timer expires, as long as the input Activation Object is 1.
The timer period is Factor x Time Base, allowing you to specify a period from 100 milliseconds
up to 255 hours.
You can choose when to activate the timer; wheter a 1, or a 0 is written to the object, or on
both edges. There is no way to cancel a non-cyclical timer that has been activated.
The value that is sent can be freely chosen.
The copy/invert of a 1 Bit object will use the “Input Value” when the timer expires, not the
value at the time of activation of the timer.
If a timer is “Resetable”, then an incoming telegram on the activation object will reset the
timer period to 0.
