Product overview
2.2 Applications of the S7-1500 CPUs
System diagnostics and alarms
Integrated system diagnostics is activated by default for the CPUs. The different diagnostic
types are configured instead of programmed. System diagnostics information and messages
from the drives are displayed consistently in plain text in up to three languages:
• On the CPU display
• In STEP 7
• On the HMI
• On the Web server
This information is available in RUN mode, but also in STOP mode of the CPU. An automatic
update of the diagnostics information is performed when you configure new hardware
components.
The CPU is available as a central interrupt server in up to three project languages. The HMI
takes over the display in the project languages defined for the CPU. If you require alarm texts
in additional languages, you can load them into your HMI via the configured connection. The
CPU, STEP 7 and your HMI ensure data consistency without additional engineering steps. The
maintenance work is easier.
