Citect SCADA/PowerSCADA 2016 Error Not Directing to Error Location

Hello,

I am working on PowerSCADA v8.2 (I believe equivalent to Citect SCADA 2016) and am receiving the error "Tag already defined, tags must be unique (E2077)". There is no context given for the error. Typically, by clicking the error, Studio will direct me to the location of the error. However, it does not direct me anywhere when I double click. I have gone through all variables and cannot find a duplicate. Does anyone have a way to find where the duplicate is located?

  • Thanks for the help Eric. Nothing is given in Name Field and Table. To give more context, when first building this project this error was not there. However, when I Backup the project and Restore it fresh, the error appeared.

  • That is weird. You could use the "Pack with Included Projects" command from the Studio | Projects activity, then try compiling again (turn Incremental Compile off or just compile twice to get a full compile).

    It may be a weird unexpected conflict, like naming a page the same as a Label. You may have to send the project to support if you can't find the conflict.

    Michael (Malaga)'s note about checking included projects is important as well. Even if you haven't created any, the PLS_Include, Include, System, and Library projects may be automatically included when you compile. If you accidentally modified one of them or duplicated something in your own project, that could cause a problem. 

    Since you said it happened after restoring, open the Restore dialog box and see if it shows any included projects being restored along with your main project. I believe PowerSCADA doesn't recognize PLS_Include as a system project and will (incorrectly) include it with your backup. When you restore on a different computer or in a different version of PowerSCADA, you can inadvertently overwrite the PLS_Include project with an older version. That could be causing a problem. You'd have to copy the PLS_Include project from another PC or reinstall to get the correct version back.
