You might find this approach useful (IIRC, the device simulator doesn't handle Rockwell's dot-separators well): > [@AB PLC tag import/export](https://forum.inductiveautomation.com/t/ab-plc-tag-import-export/33050/2): > > You might find [my Ethernet/IP module](https://inductiveautomation.com/moduleshowcase/module/automation-professionals-llc-ethernetip-class-1-communications) useful for this, without needing to buy it. Export the Logix 5000 project in L5X format. You can import that into an instance of my driver and it will render the data types and tags into my module’s virtual controller. OPC item syntax is identical to that in Ignition’s own Logix v21+ driver (with a handful of exceptions). For even more fidelity, do the above in another Ignition gateway, and let the first gateway connect to it with the normal v21 driver.
