When X0 = ON, the present value of timer T0 starts to up count clock
pulse by 100ms, and when its value reaches the set value, K100
(10 seconds), its contact will be activated.
When the input contact X0 = OFF or power cut, the present value of the
timer will return to “0” and the contact will turn into OFF.

When X1 = ON, the present value of timer T246 starts to up count clock
pulse by 1ms, and when its value reaches the set value K2000
(2 seconds), its contact will be activated.
During the timer is counting, if the X1 turned OFF or power cut, the T246
will pause counting and retain the present value. After the X1 turned ON
again, it will resume counting to increase its present value continually,
until its present value = set value K2000 (2 seconds) and its contact will
become ON.
When X2 = ON, the present value of timer T246 returns to “0” and its
contact will be OFF.
The set value of a timer can be set directly by using a constant number K or indirectly by using the content value in a
Data Registers D or R. Also, can be modified by using the Index Register V/Z.

The timers count the time are by increase counting. When the timer's Present Value = Set Value (the value designated
to a Timer), the contact of the timer is (ON).
The real Set Value of a timer = Designated number × Unit of the timer
