If X0 is ON, HT0 accumulates the
10ms pulse based on the current
value. When the accumulation value
reaches the set value K2000, the
timer output activates.
If X0 is suddenly OFF during timer
working, the timer value will be
retentive. Then X0 is ON again, the
timer will continue working.
When X2 is ON, the timer and
output will be reset.
If X0 is ON, then T0
accumulates 10ms pulse based
on the current value; when the
accumulation value reaches the
set value K200, the timer
output activates. I.e. the output
activates 2s later. If X0 is OFF,
the timer resets, the output
resets;
