Retentive timer:

A retentive timer is used when the user wants to keep the values of accumulated time during power loss or the modification in the rung state from true to false.

  • When the accumulating time of device is equal to its preset value, the connections of the device modify its states.
  • The retentive timer must be intentionally reset with different signals in order to reset the accumulated time.

Reset instruction:

  • The reset instruction is represented as RES.
  • It is used to reset value of a timer or counter.
  • It is also used to reset the accumulated value of timer.
