OPC Unified Architecture (UA): Introduction

• OPC Unified Architecture (UA) is the latest OPC standard created for industrial applications by the OPC foundation

• OPC UA combines existing standards, such as OPC DA, OPC A&E, and OPC HDA, into a Service Oriented Architecture (SOA) which is platform independent

• For more information on OPC UA, visit the OPC Foundation website (https://opcfoundation.org/about/opc-technologies/opc-ua/ ). The latest version of the OPC UA specification can also be downloaded from their website: (https://opcfoundation.org/developer-tools/specifications-unified-architecture/ )

Presentation Notes

DCOM is not only weak on security but mostly hard to get it configured right (need to setup the right credentials for the bits and pieces involved) which is why people end up opening up to much access to make it work, resulting in low security You mention OPC UA is platform independent, so is tManager (can talk to DB or JMS on non-windows systems)


OPC UA

7

Advantages • Flexibility • Can have multiple clients and multiple servers • Many participating vendors • Broad user base Disadvantages • Multiple locations to commission and maintain • Data handling

– No Store and Forward – No Failover

• Can be issues with getting mixed vendor systems to work


OPC Unified Architecture (UA): Connecting to RA Integrated Architecture

• Rockwell Automation provides products which are OPC DA 2.05 compliant. RA has worked with encompass partners to provide OPC UA connectivity to Integrated Architecture.

Presentation Notes

OPC being ‘open’ also limits what can be done to the standard. Some proprietary protocols might offer more functionalities OPEN sells but PROPRIETARY works… For the OLDI product emphasize that we publish UDTs as “OPC UA spec undefined complex data” and the newest OPC UA clients read and write CLX UDTs correctly via the OLDI module

What are the Elements of an OPC UA System?

Server

• Configure to access tags from the PLC • Note: Tags configured in Appliance Manager UI may be marked as visible

(read-only) and/or writeable

Client application

• Client will connect to Server(s) • Reading: “Subscribe” to the values that it wishes to receive • Writing: Any tags can be selected from the list posted by the server • Note: Only tags configured in Appliance Manager UI as visible and/or

writeable may be read and/or written in the client

Server

• Once the client application has “subscribed” to a tag, the server will provide the value for that tag when its value changes to the client

• Support Read/Write requests from the client

Presenter

Presentation Notes

Note: Tags configured in Appliance Manager UI may be marked as visible (read-only) and/or writeable Note: Only tags configured in Appliance Manager UI as visible and/or writeable may be read and/or written in the Client.


In this Example, the OLDI OPC UA Server Performs the Following:

– Supports the three client security options – Supports configuration of the support PAC/PLCs and provides the tag

list for selection – Supports “subscribe” requests from the OPC UA client applications – Accepts “write” requests from the OPC UA client applications – Accepts immediate “read” requests from the OPC UA client

applications – Configuration of the eATM using the OLDI GUI

• Using application to show what a OPC UA client will see • Verification of the value change using • to view the controller • as an example OPC UA client

Presenter

Presentation Notes

Enumerate the security options??? Oh, looks like you enumerate them later. All of them work now, so they can be un-grayed. .


Tag Write/Read Support

• Tag visibility & availability: – Tags presented in Appliance Manager UI’s Tag Browser are available to the

OPC UA client when they are configured as Visible (READ) and/or Writeable (READ/WRITE)

– UDTs are supported. OPC UA Server can read an entire UDT with a single request for efficiency, but only allows writing to individual elements

• Reading: Immediate Read and Subscribe support. For supporting “subscribe” requests, we will be monitoring the values of the tags that have been subscribed to and transmitting their values on change

• Writing: Accepting “write” requests and updating the PAC/PLC tags

OPC Unified Architecture (UA): Why Developed

• In 2008, the OPC Foundation released OPC Unified Architecture (OPC UA), a platform independent service-oriented architecture that integrates the functionality of OPC Classic and created to address: – Microsoft de-emphasizing COM (Component Object Model) and DCOM

(Distributed COM) in favor of cross-platform SOA (Service Oriented Architecture)

– OPC vendors wanting a single set of services for OPC data – Need to implement on non-Microsoft systems….including embedded

devices – Need for efficient way to transport high-level structured data – Ability to access OPC servers through firewalls in a secure manner

62

Source: OPC Foundation



OPC Unified Architecture (UA): Functional Equivalence

• OPC UA was designed to enhance and surpass the capabilities of the OPC Classic specifications: – Discovery: find the availability of OPC Servers on local PCs and/or networks – Address space: all data is represented hierarchically (e.g. files and folders)

allowing for simple and complex structures to be discovered and used by OPC Clients

– On-demand: read and write data/information based on access-permissions – Subscriptions: monitor data/information and report-by-exception when values

change based on a client’s criteria – Events: notify important information based on client’s criteria – Methods: clients can execute programs, etc., based on methods defined on the

server

63



OPC Unified Architecture (UA): Platform Independence; Extensible

• Given the wide array of available hardware platforms and operating systems, platform independence is essential. OPC UA functions on any of the following and more: – Hardware platforms: traditional PC hardware, cloud-based servers, PLCs,

micro-controllers (ARM, etc.) – Operating Systems: Microsoft Windows, Apple OSX, Android, or any

distribution of Linux, etc.

• The multi-layered architecture of OPC UA provides a “future proof” framework. Innovative technologies and methodologies such as new transport protocols, security algorithms, encoding standards, or application-services can be incorporated into OPC UA while maintaining backwards compatibility for existing products.

64



OPC Classic

65

• The OPC Classic specifications were based on Microsoft Windows technology using the COM/DCOM (Distributed Component Object Model) for the exchange of data between software components. The specifications provide separate definitions for accessing process data, alarms and historical data. – OPC Data Access (OPC DA)

The OPC DA specification defines the exchange of data including values, time and quality information

– OPC Alarms & Events (OPC AE) The OPC A&E specification defines the exchange of alarm and event type message information, as well as variable states and state management

– OPC Historical Data Access (OPC HDA) The OPC HDA specification defines query methods and analytics that may be applied to historical, time-stamped data

OPC Unified Architecture (UA): Overview

• OPC Unified Architecture is a platform independent service-oriented architecture that integrates the functionality of the individual OPC Classic specifications into one extensible framework

• Multi-layered approach accomplishes the original design goals of: – Functional equivalence: all COM OPC Classic specifications are mapped to UA – Platform independence: from an embedded micro-controller to cloud-based

infrastructure – Secure: encryption, authentication, and auditing – Extensible: ability to add new features without affecting existing applications – Comprehensive information modeling: for defining complex information

OPC Unified Architecture (UA): Connecting ViewSE or other OPC DA Client

• Connecting ViewSE or other integrated architecture OPC DA Client software to a ControlLogix controller via OPC UA Server. This architecture provides OPC UA connectivity across the communications path between the controller rack and the data server and OPC DA connectivity between the data server and the OPC Client
