For 32 bits binary increment counter, its valid bound is K1~K2,147,483,647
(Decimal constant). With special auxiliary relay M8238, assign the direction of
bits positive/negative counter’s (C300~C498) direction
z If X2 drives M8238, then it is
negative count；If no drive, then it is
positive count.
z According to constant K or to the
content of data register D, set the
value to be positive. Treat contents
in consecutive data register as a
pair, and dispose it as 32 bits data.
So, when assign D0, dispose D0
and D1 as a 32 bits set data. If use
count input X004 to drive coil
C300, execute increase count.
32 bits counter For normally use or power count retentive
z When reset input X3 is ON, execute RST instruction, counter’s current
value turns to be 0, output contact resets.
z When use counter as power cut retentive, counter’s current value, output
contact’s action and reset status cut power retentive.
z 32 bits counter can also be used as 32 bits data register. But 32 bits data
register can’t be used as device in 16 bits applied instructions.
