Hello Seroj; If your diagnostic OBs are downloaded to the CPUs load memory, they will be accessed by the CPU's operating system in case a related fault happens, and prevent the CPUs from going to STOP mode -- even if there is nothing programmed inside them It is the interface of each OB that is required for the diagnostic features to work, not the contents. If you need to have special things done when the OBs are active, you may choose to program some code inside the OBs. As an example, follow the discussion that was held here: /tf/WW/en/Posts/44178 To show the contents of the diagnostic buffer in your HMI, follow these FAQs on System Error Reports, both in WinCC and in WinCC Flexible: System error reports/WinCC http://support.automation.siemens.com/WW/view/en/23596958 System error reports/WinCC Flexible http://support.automation.siemens.com/WW/view/en/22319131 |
