Hello, In this manual http://support.automation.siemens.com/WW/view/en/1105178 In chapter 11.4, they explain how you can get diagnostic data from OB82 (channel diagnosic). You should use theFC 5 DIAG_RD. The function DIAG_RD can only be called in the interrupt OB82. The FC DIAG_RD executes the following actions: Reads 16 bytes of diagnostic data from the FM 350-2 Enters these data in the counter DB in the data area DIAGNOSTIC_IN_INFO. These data contain the diagnostic status of the whole module (covering all counters). |
