Value Definitions
Setting Value Description
Apply safe state value
The value configured in the Safe state is forwarded as valid to the appli-
cation as soon as communication disturbance occurs.
Keep value
The disturbed quality attribute is overwritten with
good
and the received
value is forwarded as valid to the application. If no value was received,
the output value is assumed being in safe state.
Keep last valid value
If an invalid quality attribute is received, the last valid value is forwarded
to the application. If no value has yet been received, the output value is
assumed being in safe state.
Set value to "false"
Applies only to Boolean communication objects. Every invalid quality
attribute causes the valid value
false
to be forwarded to the applica-
tion.
Set value to "true"
Applies only to Boolean communication objects. Every invalid quality
attribute causes the valid value
true
to be forwarded to the application.
These settings of the Advanced quality attributes apply to the advanced quality attributes listed below. The
selection can vary depending on the data type.
