Bryll Posted August 23, 2016 Report Posted August 23, 2016 If you are using Step 7 Classic, locate the tag and select it, then press "ctrl"+"alt"+"Q". Then you can see where in the program the tag is used for reading and/or writing. In TIA Portal, locate and select the tag, press "shift"+"F11". The cross-ref. for the tag will pop up and show you where the tag is used for read and/or write access. Quote
