Counters The logic relay provides 16 up/down counters C1 to C16 for
use as required. The counter relays allow you to count
events. You can define an upper threshold value as a
comparison value. The contact will switch according to the
actual value.
High-speed counters, frequency counters up to 1 kHz
counter frequency.
CL-DC1 and CL-DC2 feature four high-speed counters C13 to
C16. The function is defined by the mode selected. The
counter input is connected directly to a digital input. The
high-speed digital inputs are I1 to I4.
Possible applications include the counting of components,
lengths, events and frequency measurement.

The counters of CL-LSR/CL-LST and CL-LMR/CL-LMT
function in the same way as the counters of the AC010
devices. If required, the same counters can also be used
for retentive data.
