Other technology functions
Technology modules also implement functions such as high-speed counting, position
detection, measuring functions and pulse generators (PTO, PWM and frequency output). For
compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs, these functions are already
integrated and can be implemented without additional technology modules.
SIWAREX is a versatile and flexible weighing module which you can use as a static scale for
operation.
Security Integrated
In conjunction with STEP 7, each CPU offers password-based know-how protection against
unauthorized reading out or modification of the program blocks.
Copy protection provides reliable protection against unauthorized reproduction of program
blocks. With copy protection, individual blocks on the SIMATIC memory card can be tied to
its serial number so that the block can only be run if the configured memory card is inserted
into the CPU.
In addition, you can assign various access rights to different user groups in the controller
using four different authorization levels.
Improved manipulation protection allows changed or unauthorized transfers of engineering
data to be detected by the controller.
The use of an Ethernet CP (CP 1543-1) provides you with additional access protection
through a firewall or possibilities to establish secure VPN connections.
Safety Integrated
The fail-safe CPUs are intended for users who want to implement demanding standard and
fail-safe applications both centrally and decentrally.
These fail-safe CPUs allow the processing of standard and safety programs on a single
CPU. This allows fail-safe data to be evaluated in the standard user program. The integration
also provides the system advantages and the extensive functionality of SIMATIC for fail-safe
applications.
The fail-safe CPUs are certified for use in safety mode up to:
●Safety class (Safety Integrity Level) SIL 3 according to IEC 61508:2010
●Performance Level (PL) e and Category 4 according to ISO 13849-1:2006 or according to
EN ISO 13849-1:2008
Additional password protection for F-configuration and F-program is set up for IT security.
In addition to the CPUs, further components such as SINAMICS drives dispose of integrated
safety functions. Additional information about integrated safety functions in drives can be
found in the manuals for the respective products.

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 (http://www.automation.siemens.com/salesmaterial-as/interactive-manuals/getting-
started_simatic-s7-1500/disp_tool/start_en.html).
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.

Additional information
Integrated system
diagnostics
The system automatically generates the messages for
the system diagnostics and outputs these messages via
a programming device/PC, HMI device, the Web server
or the integrated display. System diagnostics information
is also available when the CPU is in STOP mode.

Integrated Web server
The Web server lets you access the CPU data by means
of a network. Evaluations, diagnostics, and modifications
are thus possible over long distances. Monitoring and
evaluation is possible without STEP 7; all you need is a
Web browser. Make sure that you take appropriate
measures (e.g. limiting network access, using firewalls)
to protect the CPU from being compromised.

Integrated trace
functionality
Trace functionality supports you in troubleshooting
and/or optimizing the user program.
You record device tags and evaluate the recordings with
the trace and logic analyzer function. Tags are,
for example, drive parameters or system and user tags
of a CPU.
The device saves the recordings. You can read out and
permanently save the recordings with the configuration
system (ES), if required. The trace and logic analyzer
function is therefore suitable for monitoring highly
dynamic processes.
The trace record can also be displayed through the Web
server.

OPC UA
With OPC UA, you can exchange data via an open and
manufacturer-neutral communication protocol. The CPU
can act as an OPC UA DA server. The CPU acting as
the OPC UA server can communicate with OPC UA
clients.
The OPC UA Companion Specification allows methods
to be specified uniformly and independently of the manu-
facturer. Using these specified methods, you can easily
integrate devices from various manufacturers into your
plants and production processes.

Configuration control
You can use configuration control to operate different
real hardware configurations with a configured maximum
configuration of the hardware. This means that, in series
machine manufacturing in particular, you have the option
of operating/configuring different configuration variants of
a machine with a single project.
