Output Description
Status Data type: Boolean
•
Out
put = 0, if the error output combination is active.
•
Output = 1, if exactly one input is 1.
Table 102: Parameter
Parameter Description
Number of inputs 2 … 8
Discrepancy time 0 … 10 s in 1 ms increments
T
he discrepancy time defines how long the two inputs can continue
to have discrepant values after a change in either of the input signals
without this being regarded as an error.
Error output combina‐
t
ion
If no input = 1 or more than one input = 1 for the selected discrepancy
time, the function block sets its outputs to the configured error output
combination. Selected outputs switch to 1, and non-selected outputs
switch to 0.
For unused inputs (Number of inputs parameter), the corresponding value
in the error output combination is set to 0.
When a valid input combination is present again, the function block
sets to 1 the output corresponding to the input.
If a faulty input combination is already present in the first logic cycle,
the error output combination is activated without delay.
Behavior of the function block
•
Ex
actly one input must be = 1 at all times.
•
If more than one input or no input is set to 1, the last output set to 1 remains 1 for
the duration of the set discrepancy time. The Status output is 1.
•
If no input or more than one input = 1 after the discrepancy time elapses, the
outputs 1 … 8 are set to the configured error output combination. The Status
output is 0.
