Description
The Associated Interface Objects attribute (29) and Associated Interface Labels attribute (31) must be supported together.
Attribtue 29 is conditional. See CIP Volume 1:
This attribute is required if any of the following conditions are true:
- A device supports more than one CIP port and it is not possible for the PTP and CIP port numbers to be the same or
- More than one PTP port is associated with a single CIP port (e.g. PRP).
We support only one CIP port and only one PTP port.
Therefore, we don't have to support attribute 29 and 31.
