Summary:

As of v16 of the Allen Bradley firmware, predefined data types (e.g. MESSAGE, ALARM_DIGITAL etc.) no longer return the size of the structure when a tag is subscribed. This results subscriptions to structure members always returning 0.

Solution:

This issue has been fixed in v3.03.04.000 of the ABCLX driver.
