CP 443-1 for Industrial Ethernet / Manual Part B
Release 07/2010
C79000-G8976-C223−06
1 Properties and Services
1.1 Properties of the CP
The CP is intended for use in an S7-400 or S7-400H (fault-tolerant) automation
system. It allows the S7-400 / S7-400H to be attached to Industrial Ethernet.
To set up small local area networks or to connect several Ethernet devices, a
2-port switch with autocrossing and autosensing has been integrated in the CP.
Each port of the switch is designed for simple diagnostics and is equipped with a
combined RXD/TXD / LINK dual LED. For special situations, each port can also be
set to a fixed mode manually using STEP 7, for example 10 or 100 Mbps half
duplex / full duplex.
Each port can be disabled individually in the project engineering.
1.2 Communication services
The CP supports the following communication services:
S PROFINET IO controller
PROFINET IO allows direct access to PROFINET IO devices over Industrial
Ethernet. PROFINET IO can only be used via the ports of the PROFINET
interface.
− Prioritized startup
The CP supports prioritized startup. Per PROFINET IO controller, a
maximum of 32 PROFINET IO devices can be configured that support
prioritized startup. Of these 32 IO devices, simultaneous startup times with
values as low as 0.5 s can be achieved by up to 8 IO devices.
− IRT communication (isochronous real time)
IRT communication is possible in PROFINET IO.
If you are using IRT communication, no media redundancy is supported.
− Shared device
As a PROFINET IO controller, individual submodules of an IO device can be
assigned to the CP. When configuring PROFINET IO systems with shared
IO devices, make sure that you read the information in /7/.
S S7 communication with the following functions:
− PG functions
− Operator monitoring and control functions
− Data exchange over S7 connections.
1 Properties and Services
B−7
CP 443-1 for Industrial Ethernet / Manual Part B
Release 07/2010
C79000-G8976-C223−06
S S5-compatible communication with the following functions:
− SEND/RECEIVE interface over ISO transport connections;
− SEND/RECEIVE interface over TCP connections, ISO-on-TCP and UDP
connections;
With the SEND/RECEIVE interface via TCP connections, the CP supports
the socket interface to TCP/IP available on practically every end system.
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 services; corresponding to S5 protocol) via
ISO transport connections, ISO-on-TCP connections and TCP connections
Here, the SIMATIC S7-400 with the CP is always the server (passive
connection establishment) while the fetch or write access (client function
with active connection establishment) is always initiated by a SIMATIC S5 or
a device from another range / PC.
− LOCK/UNLOCK with FETCH/WRITE services (CPU-dependent; see
Chapter 2);
1.3 Further services and characteristics of the CP
S Media redundancy
Within an Ethernet network with a ring topology, the CP supports the media
redundancy protocol MRP. You can assign the role of redundancy manager to
the CP.
S Time-of-day synchronization over Industrial Ethernet according to the following
configurable method:
− SIMATIC mode
The CP receives MMS time-of-day messages and synchronizes its local
time.
You can choose whether or not the time of day is forwarded. You can also
decide on the direction in which it is forwarded.
or
− NTP mode (NTP: Network Time Protocol)
The CP sends time-of-day queries at regular intervals to an NTP server and
synchronizes its local time of day.
The time can also be forwarded automatically to the CPU modules in the S7
station allowing the time to be synchronized in the entire S7 station.

Release 07/2010
C79000-G8976-C223−06
S Addressable with the factory-set MAC address
To assign the IP address to a new CP (direct from the factory), it can be
accessed using the preset MAC address on the interface being used. Online
address assignment is made in STEP 7.
S SNMP agent
The CP supports data queries over SNMP version V1 (Simple Network
Management Protocol) according to the MIB II standard.
S Module access protection
To protect the module form accidental or unauthorized access, protection can
be configured at various levels.
S IP Access Protection (IP-ACL)
Using IP access protection gives you the opportunity of restricting
communication over the CP of the local S7 station to partners with specific IP
addresses.
S IP configuration
For the PROFINET interface, you can configure how and with which method
the CP is assigned the IP address, the subnet mask and the address of a
gateway.
As an alternative to STEP 7, you have the option of assigning the connection
configuration via a block interface in the user program (FB55: IP_CONFIG)
(see /10/).
Note: Does not apply to S7 connections.
S Web diagnostics
With the aid of Web diagnostics, you can read out the diagnostic data from a
station connected via the CP to a PG/PC with an Internet browser.
If you do not require this function, you can disable it in the STEP 7 configuration
and disable the port (properties dialog of the CP > ”IP Access Protection” tab).
S Diagnostic Buffer Extract Request
With the aid of a Web browser, the CP supports the option of obtaining an
extract of the diagnostic buffer containing the most recent diagnostic events of
the CPUs and CPs located in the same S7 station as the CP.
S Connection diagnostics with FC10 AG_CNTRL
With the FC10 AG_CNTRL function, you can diagnose connections. When
necessary, you can activate or deactivate connections using the FC or initiate
reestablishment of a connection.
S S5/S7 addressing mode
The addressing mode can be configured for FETCH/WRITE access as the S7
or S5 addressing mode (S7 addressing mode only for data blocks / DBs).

S IP double addressing detected in the network
To save you time-consuming 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
The CP remains in STOP mode.
− CP in RUN mode
There is an LED indication (BUSF LED) and an entry in the diagnostic
buffer; the CP remains in RUN mode.

3.1 Procedure / steps in installation
Caution
When installing the CP for use as a PROFINET IO controller, note the following
points about the power supply:
When using the CP in the central rack or in a universal rack operating as central
rack, you should not insert or remove the CP when the power is on. If you remove
the CP when the power supply is on, the CPU changes to STOP and indicates
“I/O error”.
After inserting the module with power applied, it is essential to turn the power
supply off and on again.
Note:
If the CP is operated without PROFINET IO, it is possible to insert and remove the
CP when the power is no without affecting the CPU.
Installing the CP involves the following steps.
Step Explanation / meaning
1. Turn off the power supply when you have
configured the CP for PROFINET IO
communication.
If the CP is configured as a PROFINET IO
controller and you remove or insert the module, the
CPU assigned in the rack changes to STOP.
2. Inserting the CP: Fit in the CP onto the rack
from the top and push in at the bottom.
The CP can be plugged into all racks with slots for
P and K bus attachment.
Notice
When using the universal rack UR1 or UR2 as an expansion rack, a communication bus transceiver is
necessary!
Suitable slots in the rack:
With the exception of the slots reserved for the
power supply, the CP can be operated in all slots
with a P and K bus attachment.
3. Secure the CP with screws.
4. Turn the power supply on again.
5. Connect the CP to Industrial Ethernet over an
RJ-45 jack.
You will find examples of network attachments in
the general Part A of this manual.

Step Explanation / meaning
6. Where necessary, connect other components to
the remaining free RJ-45 jacks.
To set up small local area networks or to connect
several Ethernet devices, a 2-port switch has been
integrated in the new CP 443-1.
With the autocrossing mechanism integrated in the
switch, it is possible to establish the connection
from a laptop or PG directly using standard cables.
A crossover cable is not necessary.
Please note the following points:
S Manual configuration
If a port is set to manual configuration and
autonegotiation is disabled, the autocrossing
mechanism is also disabled for this port. The
port then behaves like the interface of a switch.
Which cable you can use depends on the
partner device.
As default, the ports are set for automatic
configuration.
For more detailed information, refer to Section
8.2
S Connecting switches
If you connect further switches, make sure that
no ring is formed in the network.
For an MRP configuration, refer to the guidelines
for setting up MRP in the general Part A of this
manual.
You will find examples of network attachments in
the general part of this manual.

C79000-G8976-C223−06
Step Explanation / meaning
7. The remaining steps in commissioning involve
downloading the configuration data and user
programs.
Requirements:
You have configured the CP in a STEP 7
project with HW Config and NetPro for the
services you want to use.
You can connect the PG when configuring the CP
as follows:
S via MPI
S via Industrial Ethernet
For further details, refer to the general Part A of
this manual:
− for initial addressing (node initialization);
− downloading the defined configuration
The PG/PC requires a LAN attachment, for
example via a CP 1613 or CP 1411 and must have
the necessary software (for example the S7 1613
package or SOFTNET IE). The TCP/IP protocol or
ISO protocol must be installed. The protocol used
must then be applied to the S7ONLINE access
point.
8. Use the diagnostic functions during
commissioning and to analyze problems.
The following options are available:
S Hardware Diagnostics and Troubleshooting
with STEP 7;
S Communication diagnostics with NCM S7
Diagnostics
S Standard information using HW Config
S Web diagnostics
Notice
If you use the CP as a replacement (for example for a CP 443–1 “EX11”) with an
older CPU, the default communication load setting of 20% for the CPU can lead to
overload. In this case, you should set the communication load for the CPU in
STEP 7/HW Config (parameter “Scan cycle load from communication”) to a lower
value − for example 10%.
With CPUs as of version V5.1, this is unnecessary.
3.2 Replacing a module without a programming device
General procedure
The configuration data of the CP is stored on the CPU. This makes it possible to
replace this module with a module of the same type (identical order number)
without a PG.

Note
When setting the ISO protocol, remember that MAC address set previously during
configuration is transferred by the CPU to the new CP module.
For information on replacing previous modules, please refer to the section
“Compatibility”.
Module replacement: Special feature of IP address assignment from a DHCP server
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.
Notice
When replacing modules, remember that the factory-set MAC address of the new
module is different from the previous module. When the factory-set MAC address
of the new module is sent to the DHCP server, this will return either a different or
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 after replacing the module.
If you have configured a new MAC address instead of the factory-set MAC
address (generally the exception, for example when using the ISO protocol), the
DHCP server always receives the configured MAC address and the CP obtains
the same IP address as the replaced module.
3.3 Force mode
You can change the mode of the CP between RUN and STOP using the STEP 7 /
NCM S7 engineering software:
S Switch from STOP to RUN:
The CP reads the configured and/or downloaded data into the work memory
and then changes to the RUN mode.
S Switch from RUN to STOP:
The CP changes to STOP. Established connections (ISO transport,
ISO-on-TCP, TCP, UDP connections) are terminated (transitional phase with
LED display “STOPPING”);
The reaction is as follows in STOP:
− The communications connections mentioned above are terminated;
