(3) RESET_INis“H”.
(4) EveryperiodspeciedinCLOCK_PER.

returnsto“L”.
EvenifRESER_INbecomes“H”,executingRESET,RESET_INdoesnotautomaticallyreturnto

If a reset is made, the next reset will not be accepted for 5 seconds after that.
EvenifUP_AUTO(orDN_AUTO)isactivatedandTOTAL_SP(or0)isreachedwithin5seconds,
the next reset will not be made for 5 seconds from the previous reset.
z CLOCK_PER
IfINTEG_TYPEisPERIODIC(5)orPER&DEM(7),aresetismadeattheperiod(sec)settothe
CLOCK_PERparameter.
IfthevalueinCLOCK_PERissmallerthanthefunctionblock’sexecutionperiod,bit1of
BLOCK_ERR“BlockCongurationError”isset.
