3.2.12 TSEQ (Time Sequence)
Line diagram/ Symbol in SR Pin Description
TRG Input
There are totally 8 output points (Output 0-7) in the
TSEQ function block. And the Output 0 retains the state
ON and is not limited by the Input R. While other
outputs (Output 1-7) will output the ON state in time
sequence one by one and will be reset controlled by Input
R. TRG is activated signal of this instruction.
R Input
R is reset signal of this instruction, will let the output
(Output 1-7) become 0.
Q Output
Time sequence output, and it has 7 selectable outputs, it
can offer 7 outputs statuses at the same time.
The function of the time sequence is as follows.
Fig. 3.7
When you select a TSEQ instruction in the program and double click it, it will
display as above figure. And at this time you can select the output points. If you select
Output 3, Output 2 will be selected automatically, the same way for Output 4, Output
5……Output 7. It means that if you select the behind one, then all the previous ones
will be selected automatically. And you can set the ON time for this output after TRG
being ON, and the time unit can be selected as second, minute, hour.
In above figure, when the TRG become 1, then 7 outputs will become 1 one by
one. It means: First second, OUTPUT 1 become 1, then 2nd second, OUTPUT 2 will
become 1, and so on, till the OUTPUT 7 become 1 in the 7th second, then it will stop.
And the output loop will start again when there is a reset signal 1 was received on R.
Note
£
ºThe Output 0 will be in ON state all the time no matter the Input TRG is
ON or OFF. It is forbidden for the user to change.
