6.7.4 Variant Dependence
PD Invalid
PD Inputs Invalid:
Input data (device-to-master) is marked as invalid if the
device status (see section 6.1 on page 66) 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).
