panels via an inter-
net connection. Cost and network support is a consid-
eration when the plant IT department has restrictions
about outside access. It is recommended to work with
them to setup an acceptable network. The configura -
tions below are examples only. Setup and support of
these networks are beyond the ability of Vilter
TM
.
Example 1
In Figure C-9, 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-site PC to
connect to the plant PC, gain control of it, and then run
a VNC program that resides on the plant’s PC to gain ac-
cess to the Vission 20/20 panels.
