Processing details
■Operation processing
• The counter starts counting when detecting the rising edge (from OFF to ON) of (s1). It does not start counting if (s1)
remains ON. The counting is started from the value of (s3). When the count value reaches the value of (s2), (d2) turns ON.
The current count value is stored in (d1).
• A value in the range of 0 to 32767 can be specified for (s2).
• A value in the range of -32768 to 32767 can be specified for (s3). However, when a negative value is specified, the initial
value is set to 0.
• To reset the current value of the counter (d1), reset (s1) of FB directly.
