Product overview
3.3 Overview of functions
● Integrated Web server
All CPUs of the SIMATIC S7-1500 automation system support querying of the CPU via
the web server. The web server of the CPU provides the following diagnostics
possibilities:
– CPU mapping with LEDs and current operating mode
– Reading out entries from the diagnostics buffer
– Querying module states
– Querying current alarms
– Information on the status of the topology/PROFINET devices
– Transferring user data to the load memory of the CPU and managing this data
– User-programmable web pages for support of service- and commissioning-specific
● Trace functionality
All CPUs of the SIMATIC S7-1500 automation system support the trace functionality. The
trace functionality supports the recording of analog and digital tags for each cycle and
their representation as a trend with STEP 7. It is particularly useful for motion control and
closed-loop control applications.
● Integrated technology
– S7-1500 Motion Control
– Integrated closed-loop control functionality: The CPU has three PID controllers with
● Integrated security
– Know-how protection
– Access protection
– Integrity protection

machine functions
PLC Open blocks for programming motion functionality by means of PROFINET IO
and PROFIdrive interface.
The functionality supports speed-controlled axes, positioning axes, synchronous axes,
and external encoders.
integrated optimization for a wide range of closed-loop control tasks:
PID_Compact for universal closed-loop control tasks
PID_3Step for valves
PID_Temp for closed-loop temperature control tasks
Algorithms can be securely protected against unauthorized access and modification.
Extended access protection provides comprehensive protection against unauthorized
configuration changes. Authorization levels can be used to assign separate rights to
different user groups.
The system protects the data transferred to the CPU from unauthorized manipulation.
Altered or external transmission of engineering data is reliably detected by the CPU.
