SIMATIC WinCC Open Architecture Forum

Dear all,

I am not able to find the TIA Technology objects DB tags in the exported file, I am using TIA V14 SP1 and WinCC OA 3.15, how can I access those tags to WinCC OA.

Hello Chandra!

In general the Export from TIA Portal and the browsing function in WinCC OA only show Datablocks (and variables) and tags which are declared as "Visible in HMI Engineering" and "Accessible from HMI/OPC UA". Without those flags you won't find them in the export file. You may also want to activate debug flag "-dbg sym" on the S7+ driver while browsing into the TIA export file.

Best,
Daniel
