Min. operation
The parameter window “Min. operation” will be shown in Fig. 3.
5.1.7. Parameter window “Counter, X”
The parameter window “Counter, X” will be shown in Fig. 12. It is visible when the input is operated
with the function “Counter”.
Using the “Counter” function, the device is able to count the number of pulse edges at the input. A
“differential counter” is therefore available if required in addition to the standard counter. Both counters
are triggered by counting pulses but otherwise operate independently of each other. The counter always
has the same data width as the differential counter.
The function is similar with the differential counter and the standard counter. The difference is the
differential counter can reset the counter value (count from 0) and overflow by the bus counter report.
Attention: When disable the function, both key scanning and object in/out are disabled. Any key
status change will be ignored.

Parameter “Pulse detection on”
The type of input signal is defined in this parameter. It can be set whether the contact is a normally
open contact (pulse trailing edge) or a normally closed contact (pulse rising edge).Options:
