(3) Cautions for when using the same timer at two or more positions.
The timer programmed last will be valid even if the timer is set in the subprogram which is not
ladder-processed according to the branch as shown in the following circuit.

In the circuit above, when M100 is ON, the subprogram of P110 will not be processed. However,
the value of K100 programmed in the subprogram of P110 will be valid as the T30 timer value.
Therefore, when the circuit above is executed, the timer setting value will be the value of K100
(100(s) obtained by 100(ms)*100), in other words, Y10 device will be ON after 10 seconds
although the subprogram of P100 is processed.
To make a correct operation, program the circuit as shown in the next page.
