OPC Foundation Mission
“To develop a specification for applying
OLE in the process control industry.
To ensure open participation by
incorporating feedback and obtaining
acceptance from industry leaders and
end-users.”
To Create Plug & Play Device Drivers.

Alarm and Events
• Developing an interface which will
define how alarms and events are
communicated.
• Developed an extensive draft
• Creating proof of concept sample code
– ICONICS to develop sample code
ICONICS
Compliance Testing
• Define compliance testing to ensure
plug-and-play interoperability
• Establishing compliance testing centers
– US - Milwaukee
– Europe - Germany / Nuremberg

• DCOM is Distributed COM
–COM with a long wire
• OPC Based on COM … so ...
• Networking comes for free!
