Functions of timers:
The units of the timer are 1ms, 10ms and 100ms and the counting method is counting up. When the present
value in the timer equals the set value, the output coil will be On. The set value should be a K value in decimal and the
data register D can also be a set value.
The actual set time in the timer = timing unit × set value
There are three types of timers:
1. General purpose timer:
For ES/SA series MPU: The timer executes once when the program reaches END instruction. When TMR
instruction is executed, the output coil will be On when the timing reaches its target.
For EH/EH2/SV series MPU: The timer executes once when the program reaches TMR instruction. When TMR
instruction is executed, the output coil will be On when the timing reaches its target.

SV K100
When X0 = On, The PV in timer T0 will count up by
100ms. When the PV = SV K100, the output coil T0
will be On.
When X0 = Off or the power is off, the PV in timer T0
will be cleared as 0, and the output coil T0 will be
Off.
2. Accumulative type timer:
For ES/SA series MPU: The timer executes once when the program reaches END instruction. When TMR
instruction is executed, the output coil will be On when the timing reaches its target.
For EH/EH2/SV series MPU: The timer executes once when the program reaches TMR instruction. When TMR
instruction is executed, the output coil will be On when the timing reaches its target.
