7.7.4 Variant Dependence
PD Invalid
PD Inputs Invalid:
Input data (device-to-master) is marked as invalid if the
device status (see section 7.1 on page 89) of the device
is Failure . In all other states, replacement values for the
data are output for which the content cannot be output
correctly.
PD Outputs Invalid:
If a master sends the process data without explicitly
marking the data as valid by means of master command ,
the data is not used in the device. The device operates
only with the last valid data. A special behavior can,
however, be defined for various pieces of data (e.g. BNI
can configure the values collected in this state by means of
parameters).
