CP 343-1 Advancedfor Industrial Ethernet / Manual Part B
Release 06/2008
C79000-G8976-C202-04
S Recommendation: Change “individual network settings” only over MPI.
If you modify the LAN settings in the properties dialog of the CP in the “Port
Parameters” tab, these changes will be adopted by the CP and activated when
the configuration data is downloaded to the CP. In some situations, the device
may then no longer be obtainable over Ethernet.
We therefore recommend that you download configuration data to the S7
station over an MPI connection if you change this setting.
If you download the configuration data over the LAN interface, depending on
the selected setting, it is possible that the current download will not be
completed due to the changes to the configuration taking immediate effect and
an inconsistent configuration is reported.
Example:
The download is started initially with the setting TP/ITP at 10 Mbps half duplex.
If the “Individual network setting” is now changed to 100 Mbps full duplex, the
download cannot be completed.
9.2.2 Transmission speed of the gigabit interface
If you want to use transmission speed 1 Gbps, leave the interface set to
“Automatic settings”.
The connection partner must also be configured with “Automatic settings”. If the
connection partner does not support gigabit Ethernet, the data will be transferred at
the next lower speed (100 or 10 Mbps).
9.3 Influence of MPI on connections via Industrial Ethernet
If a station on MPI is added or removed, for example because a service PG has
been connected or disconnected, it is possible that active communication
connections on the communications bus are aborted. This has the following effects
on the communication connections on Industrial Ethernet:
S All S7 connections are temporarily aborted.
This does not apply when using CPUs with a separate communication bus, for
example:
CPU 318-2, CPU 317-2 PN/DP, CPU 319-3 PN/DP, CPU 315–2 PN/DP,
CPU 315F–2 PN/DP, CPU 317–2 DP, CPU 317T–2 DP, CPU 317F–2 DP,
CPU 317F–2 PN/DP, CPU 318–2 DP
S The connections on which a job on the communication bus with a data length >
240 bytes is being processed are aborted temporarily.
S FETCH/WRITE connections are temporarily aborted.
On the FC interface in the user program, the condition codes made up of the
DONE, ERROR and STATUS parameters must be evaluated in FC11 / FC12.
