  • Page 13: Overview Of System Diagnostics

    Overview of system diagnostics Properties of system diagnostics Introduction In the SIMATIC environment, the term "system diagnostics" refers to diagnostics of devices and modules. All SIMATIC products have integrated diagnostic functions that you can use to detect and remedy faults. The components automatically flag a potential fault in the operation and provide detailed information.
  • Page 14 Overview of system diagnostics 2.1 Properties of system diagnostics Consistent diagnostics from the field level all the way to the management level The various diagnostics media give you a uniform view of maintenance-related information of every automation component in the plant: System status (module and network status, alarms for system errors) are available plant-wide in a uniform display.

  • Page 15: Benefits Of Innovative System Diagnostics

    This means it is also available in the STOP CPU operating mode. Faults are detected immediately and signaled to the higher-level HMI devices, the Web server and the display of the SIMATIC S7-1500 CPU, even in STOP mode. This makes system diagnostics consistent with the actual plant state at all times.
