1 Properties and Services
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).
