WinCC V7.0 SP3 Update 6 How to have a single I/O-field which shows "TAG2" but edits "TAG1" if operator clicks on it? I linked "TAG1" to the Input Value-property and "TAG2" to the Output Value-property but this seems not to work. Changing Field Type also didn't work. I also tested with I/O-field as Input only, but linking a tag to Input Value-property or not,it never writes the entered value to the tag The idea is to send the entered value to PLC TAG1, PLC does something and returns its answer in TAG2. WinCC manuals and Information System has little documentation about I/O-fields and if there is something, the help is very unclear. Thx in advance |

A little late but in a test project with internal tags, it seems to work. I'll have to check this behaviour with external tags later on. Thanks Hariom |
