Figure 57:
Signal diagram of high-speed counter
1: count pulses at counter input I1(I2)
2: setpoint of the counter
3: actual value of the counter
4: enable of the counter, CC13 (CC14)
5: count direction, direction coil DC13 (DC14)
6: reset coil of the counter RC13 (RC14)
7: contact of the counter, C13 (C14)
• Range A: The relay contact C13 (C14) of the counter with setpoint value "512" switches as soon as the
actual value is "512".
• Range B: When new count pulses or the counter enable are not present, the actual value is retained.
• Range C: If the count direction is reversed DC13 (DC14), the contact is reset when the actual value is
511.
• Range D: the count direction is set to up counting.
• Range E: The Reset coil RC13 (RC14) resets the counter to "0". No pulses are counted.
• Range F: the Reset coil is not active, pulses are counted.
￫
In the examples it must be remembered that there may be a
time difference of up to one program cycle between the
setpoint/actual value comparison and the processing of the
result. This may cause deviations in values.
