CPU 1511-1 PN (6ES7511-1AK00-0AB0)
10 Manual, 01/2013, A5E31264526-AA
Properties
The module has the following technical properties:
● Communication:
– Interfaces
The CPU 1511-1 PN has a PROFINET interface with two ports. The two ports have
the same IP address and form the interface to the fieldbus level (switch functionality).
– Integrated Web server
The CPU status query is independent of a software installation. Graphically visualized
process variables and user-defined websites facilitate information acquisition.
● Trace functionality
– All CPUs of the S7-1500 automation system support trace functionality.
Trace functionality is independent of the technology and supports you in
debugging/optimizing the user program. It is particularly useful for Motion Control
and control applications.
● Integrated technology:
– Standard Motion Control
PLC Open blocks for programming motion functionality by means
of PROFINET IO IRT and PROFIdrive interface.
The functionality supports speed-controlled axes, positioning axes
and external encoders.
– Integrated control functionality
Universal PID controllers or 3-point controllers with integrated tuning.
Integrated temperature controller
● Integrated system diagnostics:
– System diagnostics is automatically generated and consistently displayed.
● Integrated security:
– Know-how protection
User programs can be securely protected against unauthorized access and
modification.
– Copy protection
User program blocks are linked to the serial number of the SIMATIC memory card
or of the module. User programs cannot run without the corresponding
SIMATIC memory card or module.
– Access protection
Extended access protection provides comprehensive protection against unauthorized
configuration changes. Authorization levels can be used to assign separate rights to
different user groups.
– Integrity protection
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.

Note
Removing and fitting the front panel
The front panel can be removed and replaced during runtime without affecting operation.
Note
Temperature range for display
To increase the service life of the display, the display switches itself off before the permitted
operating temperature is reached. When the display cools down again it automatically
switches itself on again. The status of the CPU continues to be indicated by the LEDs
when the display is switched off.
For more information on temperatures at which the display switches itself on and off,
refer to the Technical Specifications (Page 29).

2.4 Functions
2.4.1 PROFINET IO
PROFINET is a fieldbus standard of the PROFIBUS user organization that defines
a cross-vendor communication and engineering model.
Within the context of PROFINET, PROFINET IO is a communication concept for the
implementation of modular, distributed applications. PROFINET IO IRT enables defined
response times and high-precision system behavior.
The PROFINET IO controller operating mode enables direct access to IO devices
via Industrial Ethernet.
The PROFINET IO device operating mode enables the operation of S7 stations
as "intelligent" PROFINET IO devices on Industrial Ethernet.
UDP and RT or IRT are used to configure the cyclic IO data traffic for
PROFINET IO communication.
General properties of PROFINET IO
PROFINET IO has the following properties and functions:
● Real-time communication
● Isochronous real-time communication
● Media redundancy
● Prioritized startup
● Device replacement without exchangeable medium
● I-device
● IO controller
● Isochronous mode

2.4.3 Memory reset
Apart from a few exceptions, a "memory reset" involves clearing all internal memories
and then reading the data from the SIMATIC memory card.
Options
You have the following options for resetting the memory of the CPU:
● Using the mode selector switch
● Using the display
● Using STEP 7 V12
Procedure using the mode selector switch
Proceed as follows to reset the CPU memory using the mode sselector switch:
1. Set the mode selector switch to STOP.
Initial result: The RUN/STOP LED lights up yellow.
2. Set the mode selector switch to the MRES position. Hold the switch in this position
until the RUN/STOP LED lights up in yellow for the 2nd time and remains lit
(this takes three seconds). After this, release the switch.
3. Within the next three seconds, return the mode selector switch to the MRES position,
and then back to STOP again.
Result: The CPU executes a memory reset, during which time the RUN/STOP LED flashes
yellow. The RUN/STOP LED switches to yellow when the CPU has completed the memory
reset.

2.4.4 Restoring the factory settings of the CPU
The "Reset to factory settings" function restores the CPU to the "delivery state".
This means that all data that was stored in internal CPU memory is deleted.
Recommendation:
Always reset a PROFINET CPU to the factory state if you want to store it or remove it for
use at a different location with a different program. Make sure that the Reset to factory
settings also deletes the IP address parameters.
Options
There are three ways to reset the CPU to the factory state:
● Using the mode selector switch
● Using the display
● Using STEP 7 V12
Procedure using the mode selector switch
Make sure that there is no SIMATIC memory card in the CPU and that the CPU
is in STOP mode (RUN/STOP LED lights up yellow).
Perform a reset to factory settings when there is no SIMATIC memory card inserted,
as follows:
1. Set the mode selector switch to STOP.
Initial result: The RUN/STOP LED lights up yellow.
2. Set the mode selector switch to the MRES position. Hold the mode selector switch in
this position until the RUN/STOP LED lights up in yellow for the 2nd time and remains lit
(this takes three seconds). After this, release the switch.
3. Within the next three seconds, return the mode selector switch to the MRES position,
and then back to STOP again.
Result: The CPU executes the "Reset to factory settings"; the RUN/STOP LED flashes
yellow. The yellow state of the RUN/STOP LED indicates that the CPU is reset to factory
settings and in STOP mode. The "Reset to factory settings" event is entered in the
diagnostics buffer.
Note
Make sure to set the CPU to factory state when you remove a PROFINET CPU and use it
elsewhere or put it in storage. Make sure that the Reset to factory settings also deletes the
IP address parameters.

20 Manual, 01/2013, A5E31264526-AA
Procedure using the display
Make sure that the CPU is in STOP mode (RUN/STOP LED lights up yellow).
If a SIMATIC memory card is plugged in, make sure to remove this.
You can reach the "Factory settings" menu command by successively selecting
the following menu commands and confirming each step with "OK".
● Settings → Reset → Factory settings
Result: The CPU executes the "Reset to factory settings"; the RUN/STOP LED flashes
yellow. The yellow state of the RUN/STOP LED indicates that the CPU is reset to factory
settings and in STOP mode. The "Reset to factory settings" event is entered in the
diagnostics buffer.
Procedure using STEP 7
Make sure there is an online connection to the CPU that is to be reset to the factory settings.
1. Open the Online and Diagnostics view of the CPU.
2. In the "Functions" folder, select the "Reset to factory settings" group.
3. Select the "Retain IP address" option button to retain the IP address,
or the "Reset IP address" option button to delete the IP address.
4. Click "Reset".
5. Click "OK" to confirm the security prompt.
Result: The CPU is set to STOP mode and is reset to factory settings.
Retentive characteristics of the memory objects
The properties of the CPU are set to the following values:

Assignment of MAC addresses
The CPU 1511-1 PN has a PROFINET interface with two ports. The PROFINET interface
itself has a MAC address, and each of the two PROFINET ports has its own MAC address.
There are therefore three MAC addresses in total for the CPU 1511-1 PN.
The MAC addresses of the PROFINET ports are needed for the LLDP protocol,
for example for the proximity detection function.
The number range of the MAC addresses is sequential. The first and last MAC address
is lasered on the right of each CPU 1511-1 PN.
The table below sets out the MAC address assignment.
