There are two types of timers in Omron PLC: TIM/ TIMH

TIM – normal timer Timing time is 0~999.9 s

TIMH – High Speed Timer Timing Time is 0~99. 99 s

N:000~127 (TIM shares these numbers with TIMH)

SV : 0~9999 Unit: TIM is 0.1 s; TIMH is 0.01 s

★ Timer function

1 Timing starts when the execution condition is ON, and the execution condition remains ON during timing.

2 When the timing is up, the timer is ON and its contact is activated. Thereafter, only the execution condition remains ON and its ON state remains.

3 When the scan time Ts > 0.1 seconds, the TIM will be inaccurate; when Ts > 0.01 seconds, TIMH will be inaccurate.

4 After the timer is turned ON, if the execution condition is OFF, the timer is reset.

5 After the timer is turned ON, if the PLC is powered off, the timer is reset.

When the timer is reset, its current value is the set value.
