MONO—Monostable Multivibrator
The MONO function block is a monostable multivibrator that generates an output pulse
of duration defined by TON when a rising edge trigger is detected in the TRIG input. If a
new trigger is detected before the output pulse has completed, the pulse is stretched
out by another full pulse duration. The reset clears the OUT irrespective of the state of
TON and TRIG.
Parameter Data type Description
TON UINT Pulse duration (x1ms, x10ms, 100ms, x1s)
TRIG BOOL Input trigger
RESET BOOL Reset
OUT BOOL Generated pulse
ET UINT Elapsed time since pulse start
