z The operation for this instruction is the same as that for the basic timer (T0~T255), except that the basic
timer only has a "timing control" input - when its input is 1 it starts timing, and when input is 0 it get clear.
Every time the input changes, it starts timing again and is unable to accumulate. Timing with this instruction
is only permissible when enable control "EN" = 1. With this instruction, when timing control "TIM" is 1, it is
the same as a basic timer, but when "TIM" is 0, it does not clear, but keeps the current value. If the timer
need to clear, then change enable control "EN" to 0. When timing control "TIM" is once again to be 1, it will
continue to accumulate from the previous value when the timer last paused. In addition, this instruction also
has two outputs, "Time up TUP" (when time up it is 1, usually it is 0) and "Time not up" (usually it is 1, when
time is up it is 0). Users can utilize input and output combinations to produce timers with various different
functions. For example:
z On delay energizing timer:
X0
TIM
CV :
10
R 0
89.T1S
TUP
Y0
NUP
EN
PV :
z This timer's output (Y0 in this example) is
normally not energized. When this timer's
input control (X0 in this example) is activated
(ON), only after delay by 10 sec will output
Y0 become energized (ON).
z On delay de-energizing timer:
X0
TIM
CV :
10
R 0
89.T1S
TUP
Y0
NUP
EN
PV :
z The output Y0 of this timer is usually
energized. When this timer's input control X0
is on, only after delay by 10 sec will the
output become de-energized (OFF).
