10.7 IT Functionality − “Device Structure and Status” in the
System
As described in the “Information Technology with CP 343 − 1 IT and CP 443 − 1 IT”
manual, the diagnostic texts can only be displayed when the STEP 7 event
database is located in the file system of the CP. The STEP 7 event database must
be stored there with the following file name:
/config/S7wmeld.edb (case
− sensitive)
When the CP ships, this file in German in the file system and is located in the
following directory:
Program files\Common files\Siemens\s7wmeldb\data
You can change the language of the diagnostic messages by copying the events
database from your STEP 7 installation on a PC/PG and replacing the existing file.
The files are stored there with the naming scheme “s7wmeldb” and you must
change this to “S7wmeldx.edb”.

10.8 Possible Security Gaps on Standard IT Interfaces /
Preventing Illegal Access
With various SIMATIC NET components, such as OSMs/ESMs, a wide range of
parameter assignment and diagnostic functions (for example, Web servers,
network management) are available over open protocols and interfaces. The
possibility of unauthorized misuse of these open protocols and interfaces by third
parties, for example to manipulate data, cannot be entirely excluded.
When using the functions listed above and these open interfaces and protocols (for
example,
SNMP , HTTP, Telnet), you should take suitable security measures to
prevent unauthorized access to the components and the network particularly from
within the WAN/Internet.
Notice
We expressly point out that automation networks must be isolated from the rest of
the company network by suitable gateways (for example using tried and tested
firewall systems). We do not accept any liability whatsoever, whatever the legal
justification, for damage resulting from non-adherence to this notice.
If you have questions on the use of firewall systems and IT security, please contact
your local Siemens office or representative. You will find the address in the
SIMATIC catalog IKPI or on the Internet at
