Product overview
2.2 Applications of the S7-1500 CPU
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 immediately shown on the display in plain text. In the case of servicing, plant
downtimes are minimized by quick access to diagnostics alarms. Detailed information about
this and a multitude of other display functions is available in the SIMATIC S7-1500 Display
Simulator

Uniform front connectors for all modules and integrated potential bridges for flexible
formation of potential groups simplifies 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 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 is shown
uniformly and in plain text on the display of the CPU, in STEP 7, on the HMI and on the Web
server, even for alarms related to drives. 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 specified for the CPU. If you require message
texts in additional languages, you can load these via the configured connection to your HMI.
The CPU, STEP 7 and your HMI guarantee data consistency without additional engineering
steps. The maintenance work is easier.
