Based on standards for the Web•XML, WSDL, SOAP, WS-*WS-Policy negotiates protocol and encodingWS-SecureConversation provides secured sessionsOptimized for the Intranet• OPC Binary encoding over TCP

RobustnessRobustness

Subscription Update Features• Keep-alive (heartbeat) messages

- Allows clients to detect a failed server or channel• Sequence Numbers in each update message

- Allows client re-sync to obtain missed messages• Decouples callback channel from notification

mechanism, allowing callback channel to be reset without loss of data

Redundancy Features• Designed for easy (optional) redundancy of both

Clients and Servers- e.g. re-sync request can be sent to a backup server

11

SecuritySecurity

UA Clients present credentials to UA Servers (x509 certs on both sides).UA Servers require authentication and authorization.• Access control can be fine-grained

down to the property level.Optional message signing and encryption.

Methods vs. Methods vs. ProgramsPrograms

Programs built on top of MethodsPrograms represent executable components of objects , e.g.,• DownloadProgram(Name, InitState)• MonitorNetwork (From, Till, Interval)

Execution time may vary from milliseconds to indefinitely.Asynchronous invocation is non-blocking. Results are returned using notifications.

The client can control the execution.

Methods part of UA BaseSynchronous invocation similar to blocking function calls.• AckAlarm()

14

Complex Data FeaturesComplex Data Features

Tells clients how to parse structured dataAllows use of XML Schemas for describing XML dataDefines OPC Binary data description language that uses XML to describe binary data structures Allows client to access device specific data descriptions (e.g. Fieldbus Foundation OD)

OPC Compliance, Interoperability, and CertificationOPC Compliance, Interoperability, and Certification

OPC, It’s just that easy

By Mark Hensley

Making OPC Reliable and Making OPC Reliable and EasyEasy

What we will Cover• Issues that effect OPC reliability• How the OPC Foundation has addressed

these issues• Continued Improvement, OPC Third Party

Certification• How to know the Compliance and

Certification status of a product• What you can do

23

Problems and their Causes Problems and their Causes

The Problems:• OPC technology is complex to design• Vendor interpretations of OPC specifications

can vary• Interactions between OPC products can result

in unique issues• Quality control can vary from vendor to vendor• No guarantee of cooperation between vendorsWe want “Plug and Play” not “Plug and Pray”How do we get there?

24

OPC Compliance Test Tool (CTT)OPC Compliance Test Tool (CTT)

The OPC Foundation provides a Compliance test for OPC Server vendorsActions Performed by the Compliance test• Test the OPC Servers adherence to the specifications• Stresses basic server operation (speed, memory

management)• Generates an encrypted results file sent to the OPC

FoundationThe Server vendors can choose to submit their results to the OPC FoundationMany vendors use the OPC Compliance tool as a part of their normal testingUnfortunately at this time there is no compliance test for OPC Client products• Client applications can perform operations that negatively

impact even a compliant OPC server

25

OPC Interoperability (IOP)OPC Interoperability (IOP)

26

OPC Interoperability (IOP)OPC Interoperability (IOP)

The OPC Foundation host Interoperability Meetings each year• Multiple worldwide locations

- US, Germany, Japan

OPC Vendors test their products against each otherTesting takes a full week (12 hour days)Vendors are encouraged to bring source code and make fixes on the spotThe goal is to reduce and eliminate OPC issues before customers encounter themUnfortunately not every vendor takes advantage of this opportunity

27

Continual Continual ImprovementImprovement OPC Certification OPC Certification (Future) (Future)

True Third Party CertificationTesting Labs to be establish worldwideTest Labs will be sanctioned by the OPC FoundationTest both OPC Servers and OPC ClientsTest procedures will be standardized across all labsSpecifications for OPC Certification and Test Lab operation are well underway
