Calculation rule
● If the on threshold ≥ off threshold, then:
Q = 1, if Cnt ≥ On
Q = 0, if Cnt < Off.
● If the on threshold < off threshold, then:
Q = 1, if On ≤ Cnt < Off.
0BA0-0BA5:
The Start Value parameter does not exist. The counter always counts up or
down from 0.
0BA0-0BA3:
The off parameter does not exist. The calculation rule is therefore void.
Caution
The function polls the limit value of the counter once in each cycle.
Thus, if the pulses at the fast inputs I3, I4, I5, or I6 are faster than the scan cycle time, the
Thus, if the pulses at the fast inputs I3, I4, I5, or I6 are faster than the scan cycle time, the
SFB might not switch until the specified limit has been exceeded.
Example: Up to 100 pulses per cycle can be counted; 900 pulses have been counted so far.
Example: Up to 100 pulses per cycle can be counted; 900 pulses have been counted so far.
On = 950; Off = 10000. The output is set in the next cycle, after the value has reached 1000.
The output would not be set at all if the value Off = 980
The output would not be set at all if the value Off = 980
Scan cycle time
For information on how to determine the scan cycle time of a LOGO!, refer to the appendix in
5.3.2.2
Hours counter
Short description
A configured time is triggered with a signal at the monitoring input. The output is set when
this time has expired.
Connection
Description
Inout R
A positive edge (0 to 1 transition) at input R resets output Q and sets a
configured value MI at the counter for the duration of the time-to-go (MN).
Input En
En is the monitoring input. LOGO! scans the On Time of this input.
