Rockwell PLC with 1734-4IOL/A IO-Link Master communicating to 3rd party device. Devices without Premier IODD files normally only have a device tab called common. In the newer versions of RS5000, whilst ONLINE ONLY, now users have additional tabs: Identification, Observation, Parmater, and Diagnosis. While ONLINE to a Festo Product in the Diagnosis tab, I have named variables/parameters named Error Count, Device Status, then an array Detailed Device Status [1] to Detailed Device Status [64]. How can I programmatically get the values into my code so I can display the fault history
