You integrate a counter into your circuit in the form of a
contact and coil. The counter relay has different coils and
contacts.

incremental counter
Parameter display and parameter set for high-speed
incremental counter:
In the parameter display of a counter relay you change
setpoint values and/or the preset value and the enable of the
parameter display.
Value range
The function block operates in the integer range from
–2147483648 to 2147483647.
Each pulse is counted twice.
Example: Value at CI…QV>= 42000
The counter has counted 21000 pulses.
h
Prevent unpredictable switching states. Use each coil of a
relay once only in the circuit diagram.
Use a counter input for the CF, CH, CI counters only once.
