Timer (T)

Time counting starts when a coil is turned on, and it times out and the contact turns on when the 
current value reaches the set value.
The timer is of an incremental type.

Timers are mainly classified into the following two types.

1) Timer of which value is set to 0 when the coil is turned off.

2) Retentive timer that holds the current value even if the coil is turned off.

Also, low-speed and high-speed timers are included in timer 1), and low-speed and high-speed retentive timers 
are included in timer 2). 

The same device is used for the low- and high-speed timers, and the type is determined according to the 
instruction used.

 For the OUT T0 instruction, the low-speed timer is specified, and for the OUTH T0 instruction, the 

high-speed timer is specified.

The same device is used for the low- and high-speed retentive timers, and the type is determined according to the 
instruction used.                                

 For the OUT ST0 instruction, the low-speed retentive timer is specified, and for the OUTH ST0
