1 Properties and Services
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
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.
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 last ten diagnostic events of the
CPUs and CPs located in the same S7 station as the CP.
S Connection 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.
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.
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.
S 4−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.
