This CPU is described in the fail-safe CPUsThe compact CPUs can be used for smaller to mid-range applications and have an
integrated analog and digital on-board I/O as well as integrated technology functions. The
following table shows the specific properties of the Compact CPUs.
CPU 1511C-1 PN CPU 1512C-1 PN
Integrated analog inputs/outputs 5 inputs/2 outputs 5 inputs/2 outputs
Integrated digital inputs/outputs 16 inputs/16 outputs 32 inputs/32 outputs
High-speed counters 6 6
Pulse generators
• PWM (pulse-width modulation)
• PTO (Pulse Train Output or stepper motor control)
• Frequency output
4 (PTOx/PWMx) 4 (PTOx/PWMx)The CPUs of the SIMATIC support motion control functions. STEP 7 offers blocks
standardized according to PLCopen for configuring and connecting a drive to the CPU.
Motion Control supports speed-controlled, positioning and synchronous axes (synchronizing
without specification of the synchronous position) as well as external encoders, cams, cam
tracks and measuring inputs.
The CPUs of theSIMATIC T support advanced motion control functions in addition
to the motion control functions offered by the standard CPUs. Additional motion control
functions are absolute synchronous axes (synchronization with specification of synchronous
position) and the cam.
For effective commissioning, diagnostics and fast optimization of drives and controls, the
SIMATIC controller family offers extensive trace functions for all CPU tags.
In addition to drive integration, the SIMATIC has a PID compact closed-loop
controller; easy-to-configure blocks allow automatic optimization of the controller parameters
for optimized control quality.
Technology modules also implement functions such as high-speed counting, position
detection and measuring functions and pulse generators (PWM and frequency output). In
compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs, these functions are already
integrated and require no additional technology modules.
SIWAREX is a versatile and flexible weighing module, which you can use as a static scale
for operation.
Due to the supported technology functions, the CPUs are suitable for controlling pumps,
fans, mixers, conveyor belts, lifting platforms, gate control systems, building management
systems, synchronized axes, etc.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.
