Process Data Info and Configuration

6.7.1 Description
Process data information and configuration offers various
possibilities related to process data:
– Selection of a process dataset specified by the device
– Information about the structure of the input and output
data
– Information about the last valid value for input and
output data
As a diagnosis function, monitoring of the updates of
certain process values is available. If these are not updated
in the specified time, the device sends corresponding
diagnosis messages.
Invalid Process Data
Input data (from the device to the master) is only marked
as invalid if the device has the Failure device status.
In the case of individual pieces of faulty data, the
data is not marked as invalid but is instead
replaced by substitution values or error codes.
This is to be taken into account during the
evaluation.
Invalid output data (from the master to the device) is not
processed by the device. The device then operates only
with the last valid data.
