Compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs support technology functions such
as fast counting, pulse generators (PWM, PTO and frequency output). Due to the supported
technology functions, the compact CPUs are suitable for controlling pumps, fans, mixers,
conveyor belts, lifting platforms, gate control systems, building management systems,
synchronized axes, etc.
SIWAREX is a versatile and flexible weighing module, which you can use as a static scale
for operation.In conjunction with STEP 7 (TIA Portal), each CPU offers password-based know-how
protection against unauthorized reading out or modification of the program blocks.
The copy protection provides reliable protection against unauthorized reproduction of
program blocks. With copy protection, individual blocks on the SIMATIC memory card are
linked to its serial number so that the block can only be executed if the configured memory
card is inserted in the CPU.
In addition, four different authorization levels in the CPUs can be used to assign different
access rights to various user groups.
Improved manipulation protection allows the CPUs to detect changed or unauthorized
transfers of the engineering data.
The use of an Ethernet CP (CP 1543-1) provides the user with additional access protection
by means of a firewall and/or the option of secured 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 distributed.
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.
Design and handling
All CPUs of the SIMATIC 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. Errors
messages are immediately shown on the display in plain text, thus helping customers to
reduce downtimes.
Uniform front connectors for all modules and integrated potential jumpers 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 . The CPUs of the SIMATIC product series can be expanded
centrally and modularly 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 the easy wiring inside the control cabinet
(flexible connection consisting of front connectors with assembled single conductors).Integrated system diagnostics is enabled 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 (TIA Portal), 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 diagnostics information is updated
automatically when you configure new hardware components.
The CPU is available as a central interrupt server for 3 languages. The CPU, STEP 7
(TIA Portal) and your HMI guarantee data consistency. You can skip the various engineering
