This year I have used the following function successfully to browse bacnet:
When trying to use the same with a Control Logix PLC it always times out no matter what filtering I set.
It seems like there is simply too much data to go through and it cannot happen soon enough.
In this case we do have the PLC code, but in cases where PLC code is not available it is (I think) very valuable to be able to build an excel sheet from the browse results and then look at it in a jupyter notebook as a data exploration activity to understand how you would build a UDT for a new site or vendor.
Has anyone successfully used system.opc.browseSimple recently on an allen bradley PLC?
