ADDITIONAL NETWORK CONFIGURATIONS FOR
ACCESS VIA INTERNET
There are many network confi gurations that will allow
access to the Vilter 20/20 panels via an internet connec-
tion. Cost and network support is a consideration when
the plant IT department has restrictions about outside
access. It is recommended to work with them to setup
an acceptable network. The confi gurations below are
examples only. Setup and support of these networks are
beyond the ability of Vilter.
Example 1
In Figure B-20, this example shows a PC connected to the
internet, running a program which accesses a PC within
a plant. Both computers would have a Remote Desktop
program running on them that allows the off-sight PC to
connect to the plant PC, gain control of it, and then run a
VNC program that resides on the plant PC to gain access
to the Vission 20/20 panels.
