I have a demo working well with a handful of tags communicating to a ControlLogix PLC. However when I try to import from a more complete program (PLC with 1000’s of tags, the import button does not work). Seems like there is a limit on the list of tags Prototwin can import? I obviously do not need to import all of the tags from the PLC, so is there a method to import only a specific list (ie from an excel sheet, other method?).
The AI helper is referencing the possibility of an excel sheet import, and also an “Add Tag” button, but I cannot seem to find these.
There is no hard limit on the number of tags that you can import. If no tags appear when clicking the import button, it is likely that a tag is causing import to fail early on. This can happen if you have safety tags, which we currently don’t support.
I’d recommend setting External Access for all tags that you don’t want to read/write to None in Studio 5000 Logix Designer. If you have any safety tags, you’ll need to set the External Access for those to None in order to be able to import the other tags.
Alternatively, if you’re using V36 or later, you can use OPC UA. This will allow you to select the tags that you want to import. Although, it is still possible to hide tags from ProtoTwin by setting the OPC UA Access to None. The OPC UA driver has the additional benefit of being able to read UDTs/structs. We’ll be adding this to the Ethernet/IP driver in a future update.
Currently, importing tags from a spreadsheet is only possible with the Siemens S7 driver. We can add this capability to the Ethernet/IP driver if it would be helpful.

OPC UA was a much better solution that worked. Thanks for the tip!
