IPv4 is a 32-bit Internet Protocol addressing mechanism represented as four 8-bit
decimal values separated by dots as in: “192.168.0.148”. With the explosion of the
internet and devices using these addresses, IPv6 was introduced with a larger, 128-bit
addressing mechanism in the form of eight 16-bit hexadecimal values separated by
colons as in: “2013:08be:9ce8:0000:0000:0000:00:034d”.
Dual End Point (Task Mode Only) – Master Simulation Mode tasks always initiate a connection
on startup. If this option is unchecked, any Master Simulation Mode task will fail if the connection
is not accepted. If this option is checked, the task will wait until the initiated connection is accepted
or until it detects an outstation initiated connection.
In RTU Simulation Mode, a task will initiate a connection on startup if this option is checked
SSL Port – Port to use in conjunction with a SSL Stream Connection Type
26.3.5. DNP3 LAN/WAN – Secured Sockets Layer (SSL)
When using SSL over DNP3 LAN/WAN, the DNP3 Secure Authentication Specication requires
certicate validation for both sides. These certicates need to be obtained from a trusted
Certicate Authority (CA). The CA trusted root certicate must also be installed into the appropriate
certicate store.
• For client operations you must obtain and install into your certicate store a user certicate
with user authentication.
• For server operations you must obtain and install into your local computer certicate store a
server certicate.
• Beginning with 2.20, you can now pick the certicates that show up from the user store (Client)
and local computer store (Server). The certicates are matched by serial number. Note: The
certicate dropdowns will only show up/populate if you have certicates in your respective
certicate stores.

Under Windows 7 and Vista, the test set must be run “As Administrator” in order to use
