CP 343-1 Lean for Industrial Ethernet / Manual Part B

Release 09/2009

C79000-G8976-C198-06

1 Properties / Services

1.1 Application

The CP 343-1 Lean communications processor is intended for operation in a

SIMATIC S7-300 or SIMATIC C7 automation system. It allows attachment of the

S7-300 to Industrial Ethernet and supports PROFINET IO.

To integrate the CP in a linear bus or ring, to connect a further Ethernet device or

to use PROFINET media redundancy, a 2-port real time ERTEC switch with

autocrossing, autonegotiation and autosensing was integrated in the CP.

1.2 Communication services

The CP supports the following communication services:

SPROFINET IO

PROFINET IO allows direct access to IO devices over Industrial Ethernet.

−PROFINET IO device

Integration of the SIMATIC S7-300 programmable controller over the CP as

intelligent PROFINET IO device.

SS7 communication and PG/OP communication with the following functions:

−PG functions (including routing)

−Operator control and monitoring functions (HMI)

−Server for data exchange on S7 connections configured at one end only

without communication blocks on the S7-300 / C7-300 station

SOpen communications services with the following functions:

−SEND/RECEIVE interface over ISO-on-TCP, 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) over

ISO-on-TCP connections and TCP connections;

The addressing mode can be configured for FETCH/WRITE access as the

S7 or S5 addressing mode.

1 Properties / Services

B−6CP 343-1 Lean for Industrial Ethernet / Manual Part B

Release 09/2009

C79000-G8976-C198-06

−LOCK/UNLOCK with FETCH/WRITE services;

−Connection diagnostics using the user program

1.3 Other services

Within an Ethernet network with a ring topology, the CP supports the media

redundancy protocol MRP. You can assign the role of redundancy client to the

CP. There must be another node in the ring other than the MRP redundancy

manager.

STime-of-day synchronization over Industrial Ethernet using the following

configurable 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).

−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 and the time of the CPU (accuracy approx.

+/−1 second).

SAddressing using a factory-set MAC address

The CP can be reached over the default MAC address to allow an IP address to

be assigned.

SSNMP Agent

The CP supports data queries over SNMP version V1 (Simple Network

Management Protocol). It delivers the content of certain MIB objects according

to the MIB II standard and LLDP MIB.

STime of day for the diagnostic buffer

If a time master exists (using the NTP or SIMATIC mode), the time for

CP-internal diagnostic buffer is synchronized over the LAN.

SModule access protection

To protect the module form accidental or unauthorized access, protection can

be configured at various levels.

SIP 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.

CP 343-1 Lean for Industrial Ethernet / Manual Part B

Release 09/2009

C79000-G8976-C198-06

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).

SWeb 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 80.
