• Live Demonstration
• Summary
• Discussion, Questions & Answers
What is OPC UA?
• Unified Architecture
• A collaborative working effort of the OPC
Foundation and it’s members since 1994
• Objective to create a standard that
– Isn’t dependent on DCOM
– Can interoperate with non-Windows platforms
– Is more secure than the original OPC
– Removes redundant code across interfaces
Value Point #1 – Common Interface
Usage
Common Interfaces=
Less Programming=More Products

• ReadHistory
Value Point #2 - Security

UA Client(s)
Security & Performance Thoughts
•
•
•
•
•
Data throughput must be significant
Data is sensitive, no eavesdropping!
Data received must match what was sent
Work ONLY with those you trust!
Withstand attacks: replay, alteration, spoofing, DoS etc.
Value: 5
Security - Certificates
•
•
•
•
Digital Certificates are used for safe identification
A Certificate can represent a UA Server and UA Client
A Certificate can represent a Person (login)
Trust lists control access
Connect

… check my
trust list

Profiles
What is a Profile?
• An identifiable block of
functionality that is
supported:
– Methods needed
– Information Model, i.e.
Type(s) of Data being
moved
– Protocol & Security
• “Data Access” is an
example of a Profile, as
are all OPC Classic
interfaces
Why Profiles?
• Servers can “reveal”
which functionality they
support
• Clients can query a
Server’s Profiles
• UA Products can decide if
the other has the
capabilities desired
What is TOP Server?
TOP Server UA Client Driver
And if you connect the OPC UA
Client to a Remote TOP Server…
You have a secure OPC UA Tunnel:

Connect any client application to
the TOP Server UA Client driver
locally

Easily access other driver data in
the Remote TOP Server via the UA
Server Interface with No DCOM!
What is OmniServer?
•
•
•
•
User-Configurable Data Acquisition
Tool
OPC/DDE Server
–
OPC Server Interface
–
DDE Server Interface
–
FastDDE/SuiteLink Interface
Hardware Interfaces
–
RS-232, RS-422, RS-485
–
Winsock (TCP/UDP/Telnet)
–
LPT
Communicate to almost any
device, including custom designed
devices
–
Variable length, character
delimited Protocols
–
Known/Fixed Length
protocols
Applications for OmniServer
• Solves the problem of writing custom
drivers for unique devices.
• Is NOT a replacement for existing drivers.
Use for devices that have no drivers.
• Use OmniServer to interface computers
with other computers or devices with
other devices.
What is OPC Data Logger?
• OPC Client Application that logs data to text files and a
variety of ODBC databases, including SQL, MySQL,
Access, Oracle
• Allows logging based on exceptions, timers, or triggers
• Allows formatting of data presentation
• Easy configuration wizards let you start logging data
quickly
What is SLIK-DA 5 w/ UA?
• ActiveX and .NET toolkit for creating a custom
OPC DA or OPC UA server in a variety of
environments and languages
• Rapid development of a custom server
through simple properties, methods, and
events
– Hides OPC details and COM details from user
– Allows static or dynamic tag creation
