The example shows the counters C5 to C7 as retentive
counters.
The counter has the value 450 before the power supply is
switched off.

High-speed counters,
CL-DC1, CL-DC2
The logic relay provides various high-speed counter
functions. These counter function blocks are coupled directly
to digital inputs. The following functions are possible:
• Frequency counters: C15 and C16
• High-speed counters: C13 and C14.
Frequency counter
The logic relay provides two frequency counters C15 and
C16 for use as required. The frequency counters can be used
for measuring frequencies. The high-speed frequency
counters are permanently connected to the digital inputs I3
and I4.
Applications such as speed monitoring, volume
measurement using a volume counter, the monitoring of
machine running can be implemented with the frequency
counter.
