If X0 is ON, the timer T0 will count upwards
from the present time value every 10
milliseconds. If the present timer value matches
the setting value K100, the output coil T0 will be
ON.

If X0 is OFF, or there is a power cut, the present
value in T0 will become 0, and the output coil T0
will be OFF.
Setting value: Actual time measured by a timer= Unit of measurement for time x Setting value

Specification of a
setting value
Constant preceded by K, or value stored in a
data register
Constant preceded by K, or value stored in two
consecutive data registers
Change of the
present value
If the present value matches the setting
value, the counter will stop counting.
Even if the present value matches the setting
value, the counter will keep counting.
Output contact
If the present value matches the setting
value, the output contact will be ON.
Counting up: If the present value matches the
setting value, the output contact will be ON.
Counting down: If the present value matches the
setting value, the output contact will be reset to
OFF.
Resetting of a
contact
If the instruction RST is executed, the present value will becomes zero, and the contact will be
reset to OFF.
Actions of contacts
After the scan of a program is complete, the
contacts will act.
After the scan of a
