tmr
Retriggerable monostable timer.
Timer is activated on every rising edge of input g in the following way:
1. On the rising edge of input g the following operations are performed:
l Reading activation time from input t.
l
Zero setting of internal variable act (output act).
l Set output o TRUE.
. After t cycles are elapsed, from operations start, timer outputs are set in the following
way:
l output o is set FALSE
l output act stops on the last value reached (t value)
2. if, while the timer is active, input g became FALSE, timer goes on work normaly
3. if, while the timer is active a new rising edge on input g is checked, timer executes a new cycle
repeating the operations starting from point 1.
When the timer is active, output o is TRUE, output act indicates the number of milliseconds elapsed from
operations start. When output o is FALSE output act is not significant.
Input t is read only in the cycle in which the rising cycle of input g is checked. Therefore, if input t changes
while timer is enabled, output o is TRUE, the new value is not considered. This value will be used in the next
activation timer.
All times are expressed in milliseconds. Therefore, if input t is set 8, output o becomes TRUE for 8
milliseconds and output act changes from 0 to 8.
