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. 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. 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 Display 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 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.The CPU 1512C-1 PN consists of a CPU part, an analog on-board I/O module (X10) and a
digital on-board I/O module (X11 and X12). When configured in the TIA Portal, the compact
CPU therefore occupies a single shared slot (slot 1).
The properties and functions of the CPU part and the analog and digital on-board I/O
modules can be found in the subsections below. The properties describe the hardware
features of the CPU part and the analog and digital on-board I/O modules. The functions
describe the functions of the firmware of the CPU part and the analog and digital on-board
I/O modules.The following accessories are included in the scope of delivery and can also be ordered
separately as spare parts:
● 3 x front connector (push-in terminals) including cable ties
