4.17 Adapting the firewall settings
4.17.1 Overview
From a PG/PC in the plant network, you can directly access resources on the Siemens PC
system. The same applies when accessing a PG/PC from the Siemens PC system in the plant
network or in the company network.
If you want to access the Siemens PC system via the company network instead or in addition,
you must adapt the firewall settings.

You can adapt the following settings:
● Activate the remote access to the PC system (Page 73)
● Enabling SNMP communication (Page 71)
● Activation/deactivation of the file and printer release (Page 76)
● Activation of the ping execution (ICMP) (Page 88)
As a rule, you can make these settings in the Control Panel or via the prompt or a script/batch
file (relevant for series commissioning) (Page 70).
You can save and restore (Page 90) the firewall settings. (Even on different Siemens PC
systems, e.g. due to series commissioning)
