I would like to Know when a specific Module fail, I can detect this one, for to show alarm in a Wincc. First I need a example in AWL to do this.

But there is an easier way that should give you a good hand. Siemens has developped a Profibus-DP diagnosis FB 125, that you can download free and install in your project. It is available here: http://support.automation.siemens.com/WW/view/en/387257 It also comes with FC125, a simpler version of the block;FC125 will not signal the slot number of a defective module in a ET 200M rack, for example; the FB125 has that option. Simply follow the setup instructions (call the FB125 in all 3 OBs required) and use the data from the output of the block to program the messages you need. There are also templates to use with WinCC Flexible/Protool, maybe you can make use of them in your application. Hope this helps, Daniel Chartier

Those ET200M are twoin the same rack by direction profibus,I wouldliketo do diagnosticat eachET200M,(the ET200m active and ET200 inactive)I used the SFC13 butI can do diagnosticat only ET200M by rack.
