CP 343-1 Advancedfor Industrial Ethernet / Manual Part B

Release 06/2008

C79000-G8976-C202-04

S Addressing using a factory-set MAC address

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

IP address to be assigned.

S SNMP 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.

S Time 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.

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)

IP access protection provides the following options:

− Communication via the CP of the local S7 station can be restricted to

partners with specific IP addresses

− Access from a subnet, for example connected to the PROFINET interface to

another subnet can be restricted; the other subnet can, for example, be

connected to the gigabit interface.

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).

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.

This makes it possible, for example, to read the diagnostic buffers of the

intelligent modules in the rack.

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).
