CPUs
SIMATIC S7-1500 controllers are character-
ized by maximum performance capability
thanks to a high-performance backplane bus,
very short terminal-to-terminal response time
and extremely fast signal processing.
The controller (CPU) executes the user pro-
gram. The integrated system power supply of
the controller provides power to the modules
used through the backplane bus.
A fail-safe version is available for each
SIMATIC S7-1500 controller (except C-
CPUs). To use the safety functions in the TIA
Portal, you need the "STEP 7 Safety Ad-
vanced" option package.
During commissioning of the plant you can,
for example, change the IP address of the
CPU directly via the display, thus saving time
and costs. In the event of a service call, the
plant downtimes are minimized by quick ac-
cess to diagnostics alarms.
For effective commissioning and fast optimization of drives and controls, the SIMATIC S7-
1500 supports extensive trace functions for all CPU tags.
A SIMATIC S7-1500 controller also offers additional functions:
●
Communication via Ethernet/PROFINET
●
Communication via PROFIBUS
●
HMI communication
●
Communication via OPC UA
●
Web server, technology functions, system diagnostics, protection functions integrated
●

What can you do with the CPU?
SIMATICS7-1500 provides you with a variety of CPUs that can be integrated. You can
expand each CPU with I/O, communications and technology modules. If the memory and
performance of a CPU 1511-1 PN are sufficient for your application, but you also require
additional communication interfaces, then you have the option of extending the CPU with
communication modules for Ind. Ethernet, PROFINET and PROFIBUS. Modules for serial
communication are also available.
