Hardware Properties - Siemens SIMATIC S7-1500 Manual

Uniform front connectors for all modules and integrated potential jumpers for flexible
formation of potential groups simplify storage. Additional components such as circuit
breakers, relays, etc., can be installed quickly and easily because a DIN rail is implemented in
the rail of the SIMATIC S7-1500. The CPUs of the SIMATIC S7-1500 product series can be
expanded centrally and in a modular fashion with signal modules. Space-saving expansion
enables flexible adaptation to each application.
The system cabling for digital signal modules enables fast and clear connection to sensors
and actuators from the field (fully modular connection consisting of front connector modules,
connection cables and I/O modules), as well as easy wiring inside the control cabinet (flexible
connection consisting of front connectors with assembled single conductors).
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.
