PAC Terminal Secure
Strategy Distribution
Features

Description
PAC Terminal SSD (Secure Strategy Distribution™) allows you
to safely distribute a PAC Control strategy and to protect it
once it is downloaded to a controller. PAC Terminal SSD also
can ensure that new controller firmware is from Opto 22 and
has not been modified by anyone.
SSD provides a level of strategy security that is most valuable
to original equipment manufacturers (OEMs) who use Opto 22
equipment in their own systems, although it is not limited to
that application. Using this security system, you can:
• Protect strategies stored and running in a controller
• Safely distribute updated strategies and keep them
protected once downloaded
• Ensure that new firmware is from Opto 22 and has not
been modified by anyone

PAC Terminal SSD
While this is a robust and effective system, here are some
things this system will not protect:
• Original strategies on a PC. SSD does not provide password
protection in PAC Control. It only protects the compiled
strategy.
• Normal system communications, such as controller to
controller, controller to I/O, human-machine interface
(HMI) to controller, etc.
• I/O settings, such as I/O configurations, proportionalintegral-derivative (PID) loop settings, Event/Reaction
settings, etc.
• Inspection of controllers using PAC Terminal
When using Secure Strategy Distribution one user task is used.
This means that one less chart can run at a time than normal.
However, performance is otherwise unaffected.
The PAC Terminal SSD security functions are available in both a
graphical user interface (GUI) and a command line interface.
The command line interface makes it easy for you to create
batch or script files to handle the various aspects of strategy
security.
