INTRODUCTION TO THE PLC.
(REF: 1402)
Operation of a timer.
3.5 Operation of a timer.
All the timers have a status output "T" and the inputs: TEN, TRS, TG1, TG2, TG3 and TG4.
It is also possible to check, at any time, the elapsed time t since the timer was triggered.
When starting up the PLC, all the timers are initialized by setting their status "T" and their
time count to "0".
(TEN) Enable input.
It can be used to interrupt and resume the timing. It is referred to by the words "TEN" followed
by the timer number. For example TEN 1, TEN 25, TEN 102, etc.
Once the timer is triggered, if input TEN is set low (=0), the PLC stops timing; input TEN must
be set back high (=1) to resume timing.
By default, every time a timer is triggered, the PLC sets this input high (=1).
(TRS) Reset input.
It is used to initialize the timer by setting its status "T" and its timing to "0". It is referred to
by the word "TRS" followed by the timer number, for example TRS 1, TRS 25, TRS 102, etc.
Once the timer has been activated, at an up-flank (0 to 1 transition) of the TRS input, the
PLC resets the timer. The timer is deactivated and its trigger input must be activated to turn
the timer back on.
By default and every time a timer is triggered, the PLC sets this input high (=0).
(TG1, TG2, TG3, TG4) Trigger inputs.
They are used to activate the different work modes of the timer.
TG1 triggers the mono-stable mode.
TG2 triggers the delayed activation mode.
TG3 triggers the delayed deactivation mode.
TG4 triggers the signal limiting signal.
They are referred to by the words TG1, TG2, TG3, TG4 followed by a timer number and the
initial timing value (time constant). For example TG1 1 100, TG2 25 224, TG3 102 0, etc.
I2 = TEN 10
Input I2 controls the Enable input of timer T10.
I3 = TRS 10
Input I3 controls the Reset input of timer T10.
