– Counting, measuring, position detection and pulse generators
The technology functions high-speed counting, measuring, position detection and
pulse generators (PWM/frequency output/PTO) are integrated in the compact CPU.
For more information on integrated technology functions, refer to the section
Technology functions.
– Motion Control
Through technology objects, the Motion Control functionality supports speedcontrolled
axes, positioning axes, synchronous axes and external encoders, cams,
cam tracks and probes as well as PLC open blocks for programming the motion
control functionality.
For more information about Motion Control, refer to the section Technology functions.
For a detailed description of the use of motion control and its configuration, refer to the
Motion Control You can also use the TIA Selection Tool or the SIZER to create or configure axes.
– Integrated closed-loop control functionality
- PID Compact (continuous PID controller)
- PID 3Step (step controller for integrating actuators)
- PID Temp (temperature controller for heating and cooling with two separate
actuators)
● Trace functionality:
– The trace functionality supports troubleshooting and optimization of the user program,
especially for motion control and closed-loop control applications.
For more information on "Trace", refer to the Using the trace and logic analyzerThe system automatically generates the messages for the system diagnostics and
outputs these messages via a PG/PC, HMI device, the Web server or the integrated
display. System diagnostics is also available when the CPU is in STOP mode.ntegrated security:
– Copy protection
Copy protection links user blocks to the serial number of the SIMATIC memory card or
to the serial number of the CPU. User programs cannot run without the corresponding
SIMATIC memory card or CPU.
– Know-how protection
The know-how protection protects user blocks against unauthorized access and
modifications.
– Access protection
Extended access protection provides high-quality protection against unauthorized
configuration changes. You can use authorization levels to assign separate rights to
different user groups.
– Integrity protection
The system protects the data transferred to the CPU against manipulation. The CPU
detects incorrect or manipulated engineering data.
