These CPUs are described in the fail-safe CPUshe compact CPUs can be used for smaller to medium-sized applications and have an
integrated analog and digital on-board I/O as well as integrated technology functions. The
following table shows the differences in performance between the two compact CPUs.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
Frequency meter 6 (max. 100 kHz) 6 (max. 100 kHz)
Period duration measurement 6 channels 6 channels
Pulse width modulation (PWM output)
Max. 4 (up to 100 kHz) Max. 4 (up to 100 kHz)
Pulse Train Output (PTO output) Max. 4 (up to 100 kHz) Max. 4 (up to 100 kHz)
Frequency output Motion Control instructions standardized according to PLCopen for configuring and
connecting a drive to the CPU.
Motion Control supports the following technology objects:
● Speed-controlled axes
● Positioning axes
● Synchronous axes
● External encoders
● Output cams
● Cam tracks
● Measuring inputs
The technology CPUs of the SIMATIC offer enhanced Motion Control functions:
● Advanced synchronization functions
– Synchronization with specification of the synchronous position
– Actual value coupling
– Shifting of the master value at following axis
– Camming
● Up to 4 encoders or measuring systems as actual position for position control
The technology CPUs of the SIMATIC additionally support the following technology
objects: – Cam – Kinematics
● Cam
● Kinematics
● Controlling of kinematics, such as
– Cartesian portals
– Roller pickers
– Delta pickers
– SCARA
Due to the supported technology functions, the T CPUs are suitable for controlling
packaging machines, converting applications, assembly automation, etc.
Additional integrated technology functions
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 qualityTechnology 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 (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.
