able 69: 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.
The input is ignored when a rising signal edge occurs simultaneously at
the Reset to zero, Set to Reload value or Down input.
Down Data type: Boolean
A r
ising signal edge (0–1) at the Down input decreases the value of the
internal counter by “1” as long as 0 has not been reached.
1)
If the value falls below 0, the behavior depends on the Underflow behav‐
iour parameter.
The input is ignored when a rising signal edge occurs simultaneously at
the Reset to zero, Set to Reload value or Up input.
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.
Set to Reload value Data type: Boolean
A r
ising signal edge (0–1) at the input sets the value of the internal
counter to the configured value of the Reload value parameter.
The input is ignored when a rising signal edge (0-1) occurs simultane‐
ously at the Reset to zero input.
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 70: 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
Lower limit Data type: Boolean
Is 1 a
s long as the counter = 0
Overflow Data type: Boolean
See t
he Overflow behaviour parameters
Underflow Data type: Boolean
See t
he Underflow behaviour parameters
Table 71: Parameter
Parameter Description
Initialization value The parameter defines to which start value the internal counter is set
af
ter the first logic cycle.
•
Set to 0 at start
The L
ower limit output is immediately set to 1.
•
S
et to Reload value at start
If Reload value = Maximum value, then the Upper limit out
put is
immediately set to 1.
If Reload value = 0, then the Lower limit output is immediately set to
1.
•
Se
t to maximum value at start
The Upper limit out
put is immediately set to 1.
