Dear All,
I have a S7 project, not written by me. In thes project there are some alarm bits, which switch on a horn. The problem is that these bits are not set from anywhere in the project. As far as I undertand, the alarm bits are set from the SCADA (WinCC v6.0.3). But in the project there is no "Horn" option in the WinCC Explorer and there are no scripts (well, there is a single VBS script, but it is entirely commented). Does anybody know how else could those bits be set from the WinCC? The S7 program and WinCC project are operational for about 10 years.
All the best!
