– Motion Control
The Motion Control functionality uses technology objects to support speed-controlled
axes, positioning axes, synchronous axes, external encoders, cams, cam tracks and
measuring inputs, as well as PLCopen blocks for programming the motion control
functionality.
You can find a detailed description of the use of Motion Control and its configuration in
the Motion Control 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.
You can find additional information on the trace functionality in the Using the Trace
and Logic Analyzer ntegrated system diagnostics:
– The alarms for the system diagnostics are automatically created by the system and
displayed on a PG/PC, HMI device, Web server or the integrated display. System
diagnostics information is also available when the CPU is in STOP mode.● Integrated security:
– Know-how protection
The know-how protection protects user blocks against unauthorized access and
modifications.
– 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.
– 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 erroneous or manipulated engineering data.
● Additional functions:
– PROFIenergy
You can find information on the topic of "PROFIenergy" in the PROFINET function To increase its service life, the display switches off at a temperature below the permitted
operating temperature of the device. When the display cools down, it automatically switches
itself on again. When the display is switched off, the LEDs continue to show the status of the
CPU.
For more information on the temperatures at which the display switches itself on and off,
refer to the Technical specifications (Page 33).If you remove or attach the front panel of an automation system during operation,
personal injury or damage to property can occur in zone 2 hazardous areas.
Before you remove or fit the front panel, always switch off the power supply to the
automation system in hazardous area zone 2. The CPU maintains its operating mode.
You can lock the front panel to protect your CPU against unauthorized access.
You can attach a security seal or a padlock with a diameter of 3 mm to the front panel.In addition to the mechanical lock, you can also block access to a password-protected CPU
on the display (local lock) and assign a password for the display. You can find additional
information on the display, configurable protection levels and local locks in the /ET EDs for the current
