4.6.1.3 Wiring of a frequency counter
The following assignment of the digital inputs apply.
• I3 counter input for frequency counter C15.
• I4 counter input for frequency counter C16.
You only integrate a frequency counter into your circuit in the form of a
contact and enable coil. The coils and contacts have the following meanings:
4.6.1.4 Parameter display and parameter set for frequency counter:
In the parameter display of a counter relay you change the mode, the
setpoint and the enable of the parameter display.
￫
If you use C15 or C16 as frequency counters, coils DC15 or
DC16 will have no function. The counter signals are transferred
directly from the digital inputs I3 and I4 to the counters. A
frequency counter measures the actual value and does not
measure a direction.

C15-------SQ3
I8--------RC15
Contact Coil
C15 - C16 The contact switches if the actual value is greater than or equal to the
setpoint.
CC15, CC16 Enable of the frequency counter on “1” state, coil activated
RC15, RC16 Reset, coil triggered: actual value reset to 00000
￫
The frequency counter can also be enabled specifically for a
special operating state. This has the advantage that the cycle
time of the device is only burdened with the frequency
measurement when it is taking place. If the frequency counter
is not enabled, the cycle time of the device is shorter.
C15 Counter function relay number 15
