– Server for data exchange on S7 connections configured at one end only without
communication blocks on the S7300 / C7300 station
● Open communication services with the following functions:
– SEND/RECEIVE interface ISOonTCP, TCP and UDP connections
UDP frame buffering on the CP can be disabled during configuration. When
necessary, this allows you to achieve a shorter reaction time between the arrival of a
UDP frame and its evaluation on the CPU.
– Multicast over UDP connection
The multicast mode is made possible by selecting a suitable IP address when
configuring connections.
– FETCH/WRITE services (server; corresponding to S5 protocol) via ISO-on-TCP
connections and TCP connections
The addressing mode can be configured for FETCH/WRITE access as S7 or S5
addressing mode.
– LOCK/UNLOCK with FETCH/WRITE services
– Connection diagnostics from the user program
1.4
Other services
The CP also provides the following additional services:
● Media redundancy (MRP)
Within an Ethernet network with a ring topology, the CP supports the media redundancy
protocol MRP. You can assign the role of MRP client to the CP.
● Time-of-day synchronization over Industrial Ethernet
Time-of-day synchronization can be configured in the following modes:
– SIMATIC mode
The CP receives MMS time messages and synchronizes its local time and the time of
the CPU.
Accuracy approx. +/- 1 second
You can choose whether or not the time of day is forwarded. The forwarding direction
can also be selected (station > LAN or LAN > station).


Free UDP connections are supported by the
CP.
AG_SEND and AG_RECV allow the transfer of
blocks of data with the following length:

1 to 8192 bytes for ISO-on-TCP, TCP;

1 to 2048 bytes for UDP.
Restrictions for UDP

Transfer is not confirmed
The transmission of UDP frames is unconfirmed,
in other words the loss of messages is not
detected or displayed by the send block
(AG_SEND).

No receipt of UDP broadcast
To avoid communications overload of the CP due
to high broadcast load, the CP does not allow
receipt of UDP broadcasts.

UDP frame buffering
Size of the frame buffer with buffering enabled: 2
Kbytes
Note:
Following a buffer overflow, newly arriving frames
are discarded.
Execution times of the FCs AG_SEND / AG_RECV
The execution time required to process the FC blocks (AG_SEND, AG_RECV) required on
the S7-300 / C7-300 CPU is decisive for the calculation of the CPU cycle times (OB1) for
SEND/RECEIVE connections.

Characteristic data of the integrated switch
Learning addresses / deleting addresses (aging time)
The switch integrated in the CP (PROFINET interface) reads the source addresses included
in the data packets. The switch therefore learns the addresses of the end devices connected
via a port.
If the switch receives a data packet, it directs this packet only to the port via which the
appropriate end node can be reached.
The switch monitors the age of the learned addresses. Addresses that exceed the "aging
time" are deleted. The aging time is 5 minutes.
Ports can be deactivated individually
The ports of the switch integrated in the CP can be deactivated individually in STEP 7 /
HW Config. This can, for example, be used for service purposes.
To do this, open the properties dialog of the relevant port and select the "disabled" setting
under "Options > Transfer medium / duplex".
The port is turned off completely when it is disabled. The corresponding LED on the device
(for example X1P1) is then turned off.

2. Where necessary, connect another component to the remaining free RJ45 jack.
Note
Autocrossing mechanism - effects on the connectors
For small local area networks or for attaching several Ethernet devices, a 2port switch
has been integrated on the PROFINET interface of the CP.
With the autocrossing mechanism integrated in the switch, it is possible to use a standard
cable to connect the PG/PC. A crossover cable is not necessary.
Please note the following points:
 Manual configuration
If a port is set to manual configuration and autonegotiation is disabled, the
autocrossing mechanism is also disabled for this port. Which cable you need to use
depends on the partner device (network component or end device).
In the factory, the ports are set for automatic configuration.
For more information, refer to section Network settings (Page 38)
 Connecting switches
If you connect further switches, make sure that no ring is formed in the network.

Automatic setting or individual network settings
As default, the CP is configured for automatic detection (autosensing / autonegotiation /
autocrossing).
Note
In normal situations, the basic setting ensures troublefree communication. You should only
change this in exceptional situations.
If you create a manual configuration for the CP, the automatic negotiation of the network
settings (autonegotiation) is no longer effective. If, on the other hand, the communication
partner works with autonegotiation, no communication will be established.
Only use manual configuration when the communication partner works with the same
manually set configuration.
Autocrossing mechanism
The automatic setting also includes an "autocrossing" mechanism. With autocrossing, you
can connect network components and end devices using either crossover or straight-through
cables.

Notes on configuration and operation
6.3 Network settings
● In STEP 7 special diagnostics under the diagnostics object "Industrial Ethernet" in the
"Network Connection" group box
● in STEP 7 with the menu command "PLC > Module Information"
● In Web diagnostics
Further notes:
● Autocrossover
If you disable the "Automatic setting" option, autocrossing is disabled; which cable you
then use depends on the integration of the CP (network component or end device).
● 10/100 Mbps network components without "autonegotiation"
If you use 10/100 Mbps network components that do not support "Autonegotiation", it is
possible that you will have to set the mode manually in the CP configuration in STEP 7.
As default, the CP is configured for automatic detection.
● Forcing a specific network setting instead of "Autonegotiation"
If your application requires a fixed network setting instead of "Autonegotiation", both
partner devices must have the same setting.
● No reaction to Autonegotiation query with manual configuration
Remember that if you configure the CP manually, it will not react to an autonegotiation
query! As a result, a connected partner will not be able to make the required network
setting and communication will not be established.
Example:
If the CP is set to "100 Mbps full duplex", a CP connected as partner will set itself to "100
Mbps half duplex". Reason: Due to the fixed setting, no autonegotiation response is
possible; the connected partner recognizes the 100 Mbps with autosensing but
nevertheless remains in half duplex.
● Recommendation: Change "individual network settings" only over MPI
If you modify the LAN settings in the properties dialog of the CP in the “Port Parameters"
tab, these changes will be adopted by the CP and activated when the configuration data
is downloaded to the CP. In some situations, the device may then no longer be
obtainable over Ethernet.
We therefore recommend that you download configuration data to the S7 station over an
MPI connection if you change this setting.
If you download the configuration data over the LAN interface then, depending on the
selected setting, it is possible that the current download will not be completed due to the
changes to the configuration taking immediate effect and an inconsistent configuration is
reported.
Example:
The download is started initially with the setting TP/ITP at 10 Mbps half duplex. If the
"Individual network setting" is now changed to 100 Mbps full duplex, the download cannot
be completed.

6.4
Influence of MPI on connections via Industrial Ethernet
Adding/removing MPI nodes
If a station on the MPI bus is added or removed, for example because a service PG has
been connected or disconnected, it is possible that active communication connections on the
communications bus are aborted. This has the following effects on the communication
connections on Industrial Ethernet:
● All S7 connections are temporarily aborted.
Exceptions: This does not apply when using CPUs with a separate communication bus,
for example:
CPU 318-2, CPU 317-2 PN/DP, CPU 319-3 PN/DP, CPU 315-2 PN/DP,
CPU 315F-2 PN/DP, CPU 317-2 DP, CPU 317T-2 DP, CPU 317F-2 DP,
CPU 317F-2 PN/DP, CPU 319-3 PN/DP
● FETCH/WRITE connections are temporarily aborted.
On the FC interface in the user program, the condition codes made up of the DONE,
ERROR and STATUS parameters must be evaluated in FC11 / FC12.

PROFINET IO when operating other services at the same time
Sporadically used services
Note the following if you are using functions alongside PROFINET IO that affect the
configuration or the operating status (FB55, Primary Setup Tool, STEP 7, NCM Diagnostics):
Note
The functions listed above can influence the flow in PROFINET IO so that an interruption of
cyclic IO data exchange of the PROFINET IO devices lasting several seconds may occur.

6.6 Effects of multicast communication on RT communication
6.6
Effects of multicast communication on RT communication
Note
If PROFINET IO RT communication is operated at the same time as broadcast (BC) or
multicast (MC) in an industrial Ethernet subnet, RT frames can be delayed by long BC
frames or MC frames.
Among other things, these frames can be generated by the communications FCs AG_SEND
or AG_RECV.
With certain constellations, this can lead to a PROFINET RT communication abort. The
factors that influence this are the switch configurations ("switch depth"), the update time and
the MC/BC frame lengths.
You will find further information about the influencing factors as well as possible solutions in:

6.7
IP configuration
6.7.1
Detection of double IP addressing in the network
To save you timeconsuming troubleshooting in the network, the CP detects double
addressing in the network.
The reaction of the CP when double addressing is detected varies as follows:
● CP during startup
When the CP starts up (following a power down or after assigning an Ethernet address),
a query for its own IP address is sent into the network. If a response is sent in reply, the
CP does not start up! The error is indicated by the LEDs ("Stopped (STOP) with error" +
"BF" LED is displayed) and an entry is made in the internal diagnostics buffer.
The CP remains in STOP mode.
When you eliminate the cause by removing the device with the same IP address or by
changing its address, you then need to restart the CP.
● CP in RUN mode
If a double IP address is detected, the CP also reports this via the LED (BF) and
generates an entry in the diagnostics buffer.
The CP remains in RUN mode.
If the conflict is eliminated on another component, the "BF" LED goes off again.

6.8 Media redundancy
6.7.2
Obtain IP address vie DHCP: CP STOP on expiry of the lease
If you have configured “Obtain IP address from a DHCP server", when the CP starts up, it is
assigned a valid IP address by the DHCP server for a restricted time (period of the lease).
Note
STOP on expiry of the lease
The CP changes to STOP and loses the previously assigned IP address if the DHCP server
does not extend it before expiry of the lease. All communication connections are terminated.
6.8
Media redundancy
You can use the CP in a ring topology with media redundancy. The CP can only be a
redundancy client.
For more detailed information on configuration, refer to the online help of the "Media
redundancy" tab and Part A of the manual, see /1/ (Page 60).
6.9
Timeofday synchronization
General rules
The CP supports the two modes explained below for timeofday synchronization:
● SIMATIC mode
● NTP mode (NTP: Network Time Protocol)
No automatic changeover to daylight saving time is defined in NTP. As a result, you may
need to implement this changeover using a program application.

For more detailed information on configuration, refer to the online help of the "Time-of-day
synchronization" parameter group and in Part A of the manual /1/ (Page 60).

6.11 Possible security gaps on standard IT interfaces: preventing unauthorized access
6.11
Possible security gaps on standard IT interfaces: preventing
unauthorized access
With various SIMATIC NET components, such as switches, a wide range of parameter
assignment and diagnostics functions (for example, Web servers, network management) are
available using open protocols and interfaces. The possibility of unauthorized misuse of
these open protocols and interfaces by third parties, for example to manipulate data, cannot
be entirely excluded.
When using the functions listed above and these open interfaces and protocols (for example,
SNMP, HTTP), you should take suitable security measures to prevent unauthorized access
to the components and the network particularly from within the WAN/Internet.
Note
We expressly point out that automation networks must be isolated from the rest of the
company network by suitable gateways (for example using tried and tested firewall systems).
We do not accept any liability whatsoever, whatever the legal justification, for damage
resulting from nonadherence to this notice.
If you have questions on the use of firewall systems and IT security, please contact your
local Siemens office or representative. You will find the address in the SIMATIC catalog IK PI
or on the Internet at the following address:

Memory reset / reset to factory defaults
If the CP was configured with the "Status-dependent" protection level, the following two
functions are available only when the CPU is in STOP mode. You will find a setting in the
properties dialog of STEP 7 > "Options" > Module access protection tab.
Available functions
The CP has a twolevel function available for resetting memory:
● Memory reset
Following this memory reset, the CP retains the preset MAC address and the retentive
parameters. The CP is therefore immediately ready for downloads using the IP address.
The retentive parameters include:
– IP address, subnet mask and, if applicable, router address
– LAN settings
● Reset to factory settings
After resetting, the CP only contains the default MAC address (as shipped).
Note
The functions for memory reset and resetting to defaults described here do not change
the configuration data on the CPU!
If you subsequently upload the configuration data from the CPU to a PG you will always
obtain the configuration data that was previously on the CP (with parameters,
connections, IP address).
How to use the function
You can start the memory reset functions in STEP 7.
● Memory reset
– In STEP 7 V5.5 with the menu command "PLC" > "Clear/Reset"
– In STEP 7 special diagnostics with the "Operating Mode" > "Clear/Reset Module"
menu command
– In STEP 7 Professional V11 with STEP 7 special diagnostics

– In STEP 7 special diagnostics with the "Operating Mode" > "Reset to Factory Settings"
menu command
– In STEP 7 Professional V11 with "Online > Online & Diagnostics > Functions > Reset

Behavior after a memory reset
The CPU in the S7 station does not recognize that the CP memory was reset. The CP
therefore changes to the "Stopped (STOP) with error" state (see LEDs (Page 25)).
The configuration data must then be reloaded. The download of the configuration data can
be initiated by cycling the power supply (OFF → ON).
7.2
Loading new firmware
Options for a firmware update
The following alternative methods can be used to download new firmware to a SIMATIC NET
CP:
● Using the firmware loader supplied with STEP 7
Requirement for downloading:
– To download firmware, you require an Industrial Ethernet CP module in the PG/PC
(for example, CP 1613) or a normal Ethernet module with the "Softnet" software
package.
– The S7ONLINE interface must be set to the "ISO - Industrial Ethernet" protocol. It is
not possible to download using TCP/IP (and therefore not to other networks).
● Via the update center in the Web diagnostics of the CP
With this method, the CP remains in RUN mode.
You can reach the update center using Web diagnostics.
Requirement: The option "Firmware download via Web" is selected in the configuration.
Both options for loading the firmware are described in the manual Part A, see /1/ (Page 60).
LED displays when loading a firmware file
The LED combinations when loading a firmware file using the STEP 7 firmware loader can
be found in the section LEDs (Page 25).
When loading a firmware file using the update center in Web diagnostics, the LEDs of the
CP remain unchanged.

7.3 Replacing a module
If the loading with the firmware loader is interrupted, you should react as follows:
Disturbances or collisions on the network can lead to packets being lost. In such cases, this
can lead to an interruption of the firmware download. The firmware loader then signals a
timeout or negative response from the module being loaded.
In this case, turn the station off and on again and repeat the download.

Replacing a module
Note
Recommendation to reset address data if the use of the CP is changed
The following data is stored permanently on the CP:
 IP parameters when using DHCP
If the CP has already been operated in your plant and you want to use it at a different
location in the plant, it starts up with the permanently configured parameters.
If the CP has been used previously in your plant or has been repaired, delete all stored data
by resetting to the factory settings.

Replacing older modules
Distinction
When replacing existing modules with the module described here, the following variants
must be distinguished:
● Replacing a module
Describes the situation when an existing module can be replaced with a new module
simply by pulling/plugging without changing the configuration.
● Upgrading
(module replacement with compatible functions)
Describes the situation when the module described here can be used instead of an older
module as long as adaptations are made to the configuration. Here, the previously used
CP needs to be replaced in the configuration by the new CP.
Unless otherwise specified, the range of functions of the older module continues to be
supported.
You can also upgrade modules listed in "Module replacement". This is necessary when new
characteristics that were not available in the previously used module are required.

During configuration of the CP you can specify the IP configuration in the properties dialog;
one option is to obtain the IP address from a DHCP server.
Note
When replacing modules, please remember that the factoryset MAC address of the new
module is different from the previous module. When the factoryset MAC address of the new
module is sent to the DHCP server, this will return either a different or possibly no IP
address.
Ideally, you should therefore configure IP as follows:
Always configure a client ID if you want to obtain the same IP address from the DHCP server
