Definition 2003 – 2006 Verification and Implementation 2006 – 2008 Final OPC Foundation Release 2009 IEC 62541 Release 2010 – 2012

OPC UA = established OPC features+ Platform independence

+ Standard internet and IP based protocols

+ Built in security features

+ Generic object model

+ Extensible type system

+ Scalability through profiles

+ Migration path from Classic OPC

OPC UA unifies Data Access, Alarms & Events, Historical Data, etc.

One OPC server can support all specifications Legacy COM/DCOM applications interoperate

with OPC UA

OPC UA can be ported to any Operating System Increased market demand for OPC technology

on alternate platforms like UNIX, Linux, embedded operating systems

OPC UA supports C/C++, Java, .NET, etc.

Unification Simplification Classic OPC defines different address space

models for process data, alarms and historical data

Reduced system integration costs by providing a common architecture for accessing information

OPC products can now represent complex systems with OPC UA’s rich Information Model

OPC UA provides data and meta data UA Information model defines modeling

Market demand to start and stop a drive, download a file to a device, invoke a batch file and track download resp. batch process

OPC UA defines program invocation and state machines as part of the unified address space

OPC UA has been architected for speed and network performance

Transfer thousands of points per second Poll-Report-By-Exception mechanism ensures

full bandwidth control User-Selected network protocols using binary or

HTTP ensure applications can traverse almost any network topology
