SICK Flexi Compact User Manual

7.6.2.3.6 Event counter (up) V1
Overview
T
he function block counts the number of rising signal edges at the Up input.
Principle of operation
Table 63: Inputs
Input Description
Up Data type: Boolean
A r
ising signal edge (0–1) at the Up input increases the value of the
internal counter by “1” as long as the maximum value has not been
reached.
1)
If the maximum value is exceeded, the behavior depends on the Over‐
flow behaviour parameter.
Reset to zero Data type: Boolean
A r
ising signal edge (0–1) at the input sets the value of the internal
counter to 0.
1)
If, during the first logic cycle, the input is already 1, then function block does not evaluate this as a rising
si
gnal edge.
Table 64: Outputs
Output Description
Counter value Data type: UINT16
Out
puts the value of the internal counter (0 … 65,535).
Upper limit Data type: Boolean
Is 1 a
s long as the counter = Maximum value
Overflow Data type: Boolean
See t
he Overflow behaviour parameters
Table 65: Parameter
Parameter Description
Initialization value The start value of the internal counter is set to 0 in the first logic cycle.
Overflow behaviour This parameter controls the behavior of the function block when the
int
ernal counter has reached the maximum value and then another
counting pulse occurs at the Up input.
•
No overflow function
All other rising signal edges at the Up in
put are ignored.
•
O
verflow function
°
The Overflow output is 1 for the duration of a logic cycle.
°
The value of the internal counter is set to 0.
Maximum value 1 … 65,535
7.6.2.3.7 Event counter (down) V1

he function block counts the number of rising signal edges at the Down input.
