6. Parameterization
Co.bA: Counter base
By default, the display in counter mode records the incoming impulses. However, the system time
in seconds or minutes can also be used as the counter basis. In this case, the impulse input at
the gate time, which at flank PoSI (HIGH signal) counts and at LOW stands. At the flank nEGA
the logic is reversed.
EdGE: Count start / count end (edge)
The active edge indicates when to count . If the impulse acquisition is used as the counter base
PuLS is selected, then it is indicated whether at the positive edge PoSI or the negativ flank nEGA
the internal counter is incremented. If the counter base is the time, the active/HIGH control is
activated with PoSI and the passive-/ LOW control with nEGA selected. The counter reset is
always static.
PrES: Prescaler
A prescaler is used in the display so that even large numbers of impulses, e.g. 5,000,000, can be
recorded by the display . Only the pre-divided value is included for the scaling.
FILt: Limitation of the impulse length
For debouncing mechanical contacts via the selection of the filter frequency.
none Special evaluation of the impulse length.
no
2 Hz at duty cycle 1:1 => minimum impulse length 250 ms
2
5 Hz at duty cycle 1:1 => minimum impulse length 100 ms
5
10 Hz at duty cycle 1:1 => minimum impulse length 50 ms
10
20 Hz at duty cycle 1:1 => minimum impulse length 25 ms
20
50 Hz at duty cycle 1:1 => minimum impulse length 10 ms
50
100 Hz at duty cycle 1:1 => minimum impulse length 5 ms
100
500 Hz at duty cycle 1:1 => minimum impulse length 1 ms
500
End, End.C: Display end value and impulse count end value
The display value is freely linearized over the preset number of impulses. For this purpose, the
number of desired impulses is assigned to a display value. The zero point cannot be preselected.
With a down counter, the End and End.C as the start value. For the absolute counter limit values,
the settings of dI.HI and dI.Lo are used. If these are reached, all digits with the reached value
flash, which corresponds to an overflow or underflow.
