Industrial Communication for Automation and Drives - Induteq

Additional information
In a number of SIMATIC NET components (e.g.
OSM/ESM, CPs with IT functions), extensive
parameter assignment and diagnostic
functions (such as Web server and network
management) are made available via open
protocols and interfaces.
These open interfaces form an access portal
to the components which can also be misused
for clandestine, dishonest activities.
When using the above-mentioned functions
and these open interfaces and protocols (e.g.
SNMP, HTTP, Telnet), it is thus necessary to
take safety precautions which prevent
unauthorized access to the components or
the network, particularly from a WAN or over
the Internet.
Automation networks should therefore be
separated from other company networks by
means of suitable network interfaces (such
as the field-tested firewall systems).
The information provided in this brochure
contains descriptions or performance
characteristics, which in case of actual
use do not always apply as described or
which may change as a result of further
development of the products.
An obligation to provide the respective
characteristics shall only exist if expressly
agreed in the terms of contract. Availability
and technical specifications are subject
to change without notice.
