3.2.1 TOND
Line diagram/Symbol
in SR
Pin Description
Input TRG
After TRG is triggered, the time delay timer starts timing. (If
TRG stop triggering during the timing of timer, the timer will
terminate the timing.)
Parameter T
After time T, the output is on (the output signal changes from 0
to 1).
Output Q
If there is still trigger signal, when time T is up, the output will
be on.
Output P
If the property pin of the output P is connected with the
properties pin of the SLCD, the parameter of this function block
will be transferred to HMI.
Time Sequence Frame:
Function Description:
1. When the status of TRG changes from 0 to 1, the time delay timer starts timing.
If TRG holds the status 1 for a sufficiently long time, the output will be changed
to 1 after the time T has elapsed. There is a time delay between the input turning
ON and the output turning ON, that why the TOND is so called.
2. If the status of TRG input changes into 0 before the fixed time, the timer will be
reset.
3. When the status of TRG input is 0, then the reset status of the output is 0.
4. This function is applicable to override vibrations of switches, delayed start-up of
motor, delayed turning-on of lights, etc.
5. The assignment range for T is 0.01-99.99, and the time units can be set
respectively to hour (H), minute (M) and second (S). Its time accuracy can reach
0.5‰.
