Product overview
2.2 Area of application of the SIMATIC S7-1500 CPUs
Design and handling
All CPUs of the SIMATIC S7-1500 product series feature a display with plain text information.
The display provides the user with information on the order numbers, firmware version, and
serial number of all connected modules. In addition, the IP address of the CPU and other
network settings can be adapted locally without a programming device. Error messages are
shown on the display directly in plain text. When performing servicing, you can minimize
plant downtimes by quickly accessing the diagnostics alarms. Detailed information about this
and a multitude of other display functions is available in the SIMATIC S7-1500 Display
Simulator (https://support.industry.siemens.com/cs/ww/en/view/109761758).
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, since 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 types of
diagnostics are configured instead of programmed. System diagnostics information and
alarms from the drives are displayed consistently and in plain text:
• 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. The diagnostic
information is updated automatically 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.
