1 Properties and Services
Application
The CP 443-1 Advanced communications processor is designed for operation in an
S7-400 (not fault-tolerant) programmable logic controller. It allows the S7-400 to be
attached to Industrial Ethernet.
To set up small local area networks or to connect several Ethernet devices, a
4-port switch with autocrossing and autosensing has been integrated in the
CP 443-1 Advanced.
Communication Services
The CP 443-1 Advanced supports the following communication services:
SPROFINET IO Controller
PROFINET IO allows direct access to IO devices over Ind. Ethernet.
SPROFINET CBA
Use of a SIMATIC S7−400 for Component based Automation on the basis of
the new PROFINET standard of the PNO. This standard allows:
−Component technology in automation
−Graphic configuration of communication between intelligent devices instead
of laborious programming
−Vendor−independent, plant−wide engineering
SS7 communication with
−PG functions
−Operator monitoring and control functions
−Data exchange over S7 connections

B4A−7
CP 443-1 Advanced for Industrial Ethernet / Manual Part B4A
Release 01/2007
C79000-G8976-C193-06
−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 443-1 Advanced 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 third−party device / PC.
−LOCK/UNLOCK with FETCH/WRITE services (CPU−dependent; see
Chapter 2);
SOpen TCP/IP communication (as of firmware version V2.2)
To allow the user program to establish connections with other
TCP/IP−compliant communication partners and to exchange data, STEP 7
provides a UDT for the connection parameter assignment and four FBs for
high−performance data exchange. The following are supported:
−ISO-on-TCP connections
SIT functions
−Sending E-mail
−Monitoring devices and process data (HTML process control)
−FTP functions (File Transfer Protocol) for file management and access to
data blocks in the CPU (client and server functions).
STime−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 of day is also forwarded automatically to the S7 station so that the
time is synchronized in the entire S7 station.
Further services of the CP
SAddressable with the Factory-Set MAC Address
The CP can be reached using the factory-set MAC address to allow IP address
assignment; the CP supports the PST function (Primary Setup Tool).
SSNMP agent
The CP supports data queries over SNMP in version V1 (Simple Network
Management Protocol) complying with the MIB II standard.

B4A−8CP 443-1 Advanced for Industrial Ethernet / Manual Part B4A
Release 01/2007
C79000-G8976-C193-06
SIP 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.
SIP configuration
You can configure how and with which method the CP is assigned the IP
address, the subnet mask and the address of a gateway.
It is also possible, as an alternative, to assign the connection configuration to
the CP using STEP 7 or using a block interface in the user program (FB55:
CP_CONFIG) (see /Part A/).
Note: Does not apply to S7 connections.
SDiagnostic 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 last ten diagnostic events of the
CPUs and CPs located in the same S7 station as the CP.
SConnection diagnostics with FC10 AG_CNTRL (as of firmware version V2.2)
With FC10 AG_CNTRL, it is possible to diagnose connections. When
necessary, you can reinitialize connection establishment by the FC.
SS5/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).
SIP double addressing detected in the network
To save you time-consuming troubleshooting in the network, the CP detects
double addressing in the network.
When the CP starts up (after power down or after the initial addressing), the CP
queries its own IP address on the network. If there is a response, the CP does
not start up! The error is indicated by an LED (“STOP with internal error” is
displayed) and an entry is made in the internal diagnostic buffer.
S4−port switch integrated
To set up small local area networks or to connect several Ethernet devices, a
4-port switch has been integrated in the new CP 443-1 Advanced.
Each port of the switch is designed for simple diagnostics and is equipped with
a LINK and a RXD/TXD LED. Each port can also be set to a fixed mode
manually using STEP 7, for example 10 or 100 Mbps half duplex / full duplex.
As of firmware version V2.2, each port can be deactivated individually in the
project engineering.
With the autocrossing mechanism with autosensing integrated in the switch, it is
possible to use a standard cable to connect the PC/PG. A crossover cable is
not necessary.

Using Programming Blocks for the SEND/RECEIVE Interface
For some communication services, there are ready-made blocks (FCs/FBs)
available as the interface in your STEP 7 user program.
For data transfer on the SEND/RECEIVE interface, there are FCs for short and
long data records:
Table 1-3
Function Requirement
Transfer of data fields <= 240 bytes SYou require the blocks AG_SEND FC5 and AG_RECV
FC6 or alternatively the blocks AG_LSEND FC50
and AG_ LRECV FC60.
Transfer of data fields > 240 bytes SYou require the blocks AG_LSEND FC50 and
AG_LRECV FC60. These blocks are shipped with
NCM.
For a detailed description of these blocks, refer to the general part of this manual
/Part A/).
Notice
We recommend that you always use the current block versions for all module
types.
You will find information on the current block versions and the current blocks to
download from the Internet in our customer support.
http://www4.ad.siemens.de/view/cs/en/8797900
With the older module types, this recommendation assumes that you are using the
latest firmware for the particular block type.

Key to table 2-1 continued
1) Caution:
The AG_LRECV call with long data (data > 240 bytes) occupies both a send and a receive resource. This
affects the configuration limits of the SEND/RECEIVE interface (AG_SEND) .
This means that if you use AG_LRECV calls with long data (data > 240 bytes), this reduces the number
of AG_SEND/AG_LSEND calls that can be sent at the same time, as follows:
Number of AG_SEND/AG_LSEND in total
= number of AG_SEND/AG_LSEND maximum −number of AG_LRECV with long data
Example:
This means, for example, at a maximum of 64 possible AG_SEND calls: At the absolute limit with 64
AG_RECV calls with long data sent at the same time, no calls with AG_SEND can be sent because the
available send resources are then occupied.
2) Note
The maximum value shown here applies to the CPU being used; if several CPs are operated at the same
time, the maximum value applies unchanged to the total number of jobs issued by the CPU.
Example: If you use two CPs, via which a CPU 414-3 operates a total of 100 connections, only 24 jobs can
be processed directly at any one time.
3) Note
When operating the CP as a PROFINET IO controller, multiprocessing is not supported; in other words,
only process image of the assigned CPU can be distributed over the CP. (Note: this does not affect
communication protocols operating alongside in multiprocessing mode).

5. 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 4-port switch has been
integrated in the new CP 443-1 Advanced.
With the autocrossing mechanism integrated in the
switch, it is possible to use a standard cable to
connect a laptop or PG directly. A crossover cable
is not necessary.
Please note the following points:
SManual configuration
If a port is set to manual configuration, the
autocrossing mechanism is also deactivated 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
10.2
SConnecting switches
If you connect further switches, make sure that
no ring is formed in the network.
You will find examples of network attachments in
the general Part A of this manual.

Step Explanation / Meaning
6. The remaining steps in commissioning involve
downloading the configuration data and user
programs.
Requirement:
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:
Svia MPI
Svia Industrial Ethernet
For more detailed information is, please refer to
/Part A/:
−First 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.
7. User diagnostics for commissioning and to
analyze problems. The following options are available:
SHardware diagnostics and troubleshooting with
STEP 7
SCommunication diagnostics with NCM S7
Diagnostics
SStandard information using HW Config
8. Optional when using with PROFINET CBA:
Download PROFINET CBA component
If the S7 station in which the CP is operated is used
as a PROFINET CBA component, the
interconnections are downloaded using SIMATIC
iMap; for more detailed information, refer to the
topic “Using the CP with PROFINET CBA”.
Caution
Remember the following points regarding the power supply during installation:
SWhen using the CP in the central rack or in a universal rack operating as the
central unit, the following applies:
The CP 443-1 Advanced should not be inserted or removed while the power
supply is on. If you remove the CP when the power supply is on, the CPU
changes to STOP and indicates ”I/O error” (in contrast to previous modules!).
After inserting the module with power applied, it is essential to turn the power
supply off and on again.
SWhen using the CP in a universal rack operating as an expansion unit, the
following applies:
Before removing or inserting the CP, turn off the power supply of the expansion
unit. The CPU can then continue to operate and recognizes the ”rack return
signal” when the power supply of the expansion unit is turned on again.

3.2 C−PLUG (Configuration Plug)
Exchangeable C−PLUG
The CP has an exchangeable configuration plug (C-PLUG). This can store up to
32 MB of data in nonvolatile memory.
The retentive parameters include:
SIP address and IP parameters
SA newly set MAC address
SLAN settings
SInterconnection information for PROFINET CBA
SData in the flash file system (see also Flash Area in Section 5.10 Memory
Organization)
SSNMP Variables (modifiable)
This configuration plug simplifies replacement of modules. By simply exchanging
the plug, all the data can be transferred to the replacement module.
Notice
The CP will not start up without a C−PLUG!
Area of Application
The C−PLUG is an exchangeable medium for storing configuration and project
engineering data of the basic device (CP 443−1 Advanced). This means that
configuration data remains available if the basic device is replaced.
Principle
The power is supplied by the basic device. When powered down, the C−PLUG
retains all data permanently.

Inserting in the C−PLUG Slot
The slot for the C−PLUG is on the rear panel of the device.
The C−PLUG is inserted in the receptacle.
Figure 3-1 Fitting the C−PLUG in the CP and Removing It from the CP with a Screwdriver
Function
If the C−PLUG has not yet been written to (as shipped), when the device starts up,
all the configuration data of the CP is saved automatically on it.
If the C−PLUG is inserted, the basic device automatically uses the configuration
data of the C−PLUG. This assumes that the data was written by a compatible
device type.
If a fault occurs, the basic device can then be replaced much faster and more
simply. If a device needs to be replaced, the C−PLUG is simply taken from the
failed component and inserted in the replacement. As soon as it starts up, the
replacement automatically has the same device configuration as the failed device.
Using a C−PLUG with old Configuration Data
Use only C−PLUGs that are formatted for the CP 443−1 Advanced. C−PLUGs that
have already been used and formatted in other device types must first be
formatted for the CP 443−1 Advanced.
You do this with STEP 7 / NCM Diagnostics. For more detailed information, refer to
the online help in the topic ”General Diagnostics Functions −C−PLUG Diagnostics
Object”.
After formatting, all data areas are deleted on the C−PLUG. Project engineering
data is adopted by the CPU only after reloading or after turning on the power
supply again.
Removing the C−PLUG
It is only necessary to remove the C−PLUG if a fault occurs on the CP (see
Figure 3-1).

Diagnostics
Inserting a C−PLUG containing the configuration of an incompatible device type or
general malfunctions of a C−PLUG are signaled by the diagnostic mechanisms of
the CP (F−LED red).
3.3 Module Replacement without PG
General Procedure
The configuration data for the CP 443-1 Advanced is stored on the CPU; this
means that the module can be replaced with the module of the same type
(identical order number) without a PG.
For information on replacing previous modules, please refer to the section
”Compatibility”.
Notice
The ”Replace module without PG” functionality (configuration data stored on the
CPU) can no longer be used fully after downloading PROFINET CBA
interconnections since the interconnection information is stored only on the CP.
You have the following two options:
SAdopt the C−PLUG in a new module
You insert the previously used C−PLUG in the replaced module; this makes the
interconnection information is available again.
SUse a new module with a new C−PLUG
After replacing a module, you must download the interconnection information to
the new CP using SIMATIC iMap.
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), the DHCP server always receives the
configured MAC address and the CP obtains the same IP address as the replaced
module.
