Handling timers as numeric devices

In timers, the output contact operating in accordance with the set value is used in some cases, and the
current value is used as numeric data for control in other cases.
The figures below show the structure of timer current value registers. When a timer number is specified in an
input variable of an instruction, the timer is handled as a device which stores 16-bit or 32-bit data in the same
way as data registers.

When M3 is connected as shown in the
left figure, M2 and M1 become flicker outputs.

When X000 is set to OFF, M0, M1 and M3 turn
OFF and T10 is reset after the set time.

Do not use the timers used here in other
general circuits again.
