Description
•
External encoder for detecting the actual position of
an encoder and its use as a master value for syn­
chronous operation
•
Cams, cam track for position-dependent generation
of switching signals
•
Measuring input for fast, accurate and event-depend­
ent sensing of actual positions
•
PID Compact (continuous PID controller)
•
PID 3Step (step controller for integrating actuators)
•
PID Temp (temperature controller for heating and
cooling with two separate actuators)
The know-how protection protects user blocks against
unauthorized access and modifications.
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 correspond­
ing SIMATIC memory card or CPU.
You can use authorization levels to assign separate rights
to different users.
The CPUs feature an integrity protection function by
default. This helps to detect any manipulation of the
engineering data on the SIMATIC Memory Card or during
data transfer between the TIA Portal and the CPU, and to
check communication from a SIMATIC HMI system to the
CPU for possible manipulation of engineering data. The
user receives a corresponding message about manipula­
tion of engineering data detected by the integrity protec­
tion.
As an alternative to manual password input you can con­
nect a password provider to STEP 7. A password provider
offers the following advantages:
•
Convenient handling of passwords. STEP 7 reads the
password automatically for the blocks. This saves you
time.
•
Optimum block protection because the users do not
know the password itself.
