Hi, here's the situation: I copied the program from the PLC. On my laptop I have an older version of that same PLC-program. I have to upgrade my old version to be the same as the program on the PLC.I compare them, and found some differencies. Used OES is v4.8.5. The standards are the same. Q1: What can I do to not have this Module1.Extension.rStationData REF= DataHandling.StationData.Module1; line in StationUnit.OnApplyParameter exported from the OES into Twincat? A new export from OES does not solve my issue. I also tried with reloading standards, I got the same results. old version on left side // version from PLC on the right side Q2: I have 4 OpconDatAccess addons on Module1 level (TypeDataAccessModule1, ResultDataAccessModule1, CgDataAccessModule1, GrrDataAccessModule1). What has to be set in OES to have rStationData : REFERENCE TO Module1StationDataStruct; exported into TypeDataAccessModule1Addon (FB) in Twincat? I have the same problem with all four addons. I can't add that Module1StationDataStruct structure as reference in OES. On Station level the DistributeToModelTree parameter is checked for StationData as shown on the screenshot. Thanks!
