Hello Bip, therefore, you need a diagnostic repeater. The diagnostic repeater allows rapid localization of line faults which occur during the operation at the PROFIBUS-DP. Line faults are made visible by the LEDs at the diagnostic repeater. A detailed diagnostic display is carried out via STEP 7 or COM PROFIBUS. With STEP 7 it is possible to display the following information for the diagnostic repeater with the order number 6ES7 972-0AB01-0XA0: • The topology as a graphic or in tabular form • Diagnostic buffer • Statistics buffer In the user program this information can be read out and displayed on an HMI device, for example. To implements this, you need the RD_REC block for reading out special data sets. Look at this manual, especially chapter 7.3 http://support.automation.siemens.com/WW/view/de/7915183 Greetings, Pittiplatsch |
