Dear Sirs, I have a S7 project, which was not made by me. In the project, there is an FB with some alarm variables, which switch on a horrn. The problem is that they are used nowhere else but this FB. In the same time I have the alarms switched on just as those variables go into 1. In the alarm-processing FC there also are the variables, which are supposed to be set into 1 by those from the FB. But they are also not set from anywhere in the S7project. First I thought that they can be set from the WinCC (v6.0.3), but it seems that they aren’t. IntheWinCC Explorerthere is no “Horn” option and there arealsono scripts (actually there is one (attached), but it is entirely commented). I can’t understand how the alarm signals are transmitted from FB to FC (the project is operational for about 10 years, the alarms are displayed, the horn is yelling, everything runs great). Could anybody help please? I'm attaching a screenshot with the FB and FC I've mentioned. All the best! Attachmentalarms.zip (243 Downloads) |

Hi Inugami, you can send us the STEP 7 program? So it's a bit difficult to understand. |
