address space under a specific Topic (the first branch under the
tree root RSLinx OPC Server) and click Connect.
If the selected AOI instance tag does not correspond to the fuzzy
project in FuzzyDesigner, the following message appears.
IMPORTANT
The AOI instance Tag can be accessed through a Topic tied to
corresponding Logix controller. If an RSLogix 5000 project is
saved, then a default RSLinx Topic is created with a default
name that corresponds to the Controller Name. To make sure
that the selected RSLinx Topic corresponds to the correct
controller or to reconfigure or create a new RSLinx topic, follow
the steps described in the Appendix K – Configuring RSLinx
OPC Server Topic.
If the AOI instance Tag cannot be found, then check if the
RSLinx topic is correctly configured as explained above.
