OPC and the 5000 - What is OPC?

• “OLE for Process Control”

• Defines common ways for applications to access field, process or plant data

• A collection of standards– Data Access

– Alarms & Events

– Historical Data

...

• Based on Microsoft Windows standards

• “Ostrich for Process Control”

6

OPC and the 5000 - Some History: up to 1990

• Before Windows 3.0– single-tasking DOS computers

– no established need for interoperability standards

7

OPC and the 5000 - Some History: 1990-92

• Windows 3.0– a multi-tasking computer on every desktop

– Dynamic Data Exchange (DDE) allows live transfer of data between programs

» defines transport mechanism, not data formats

– proprietary ways of using DDE for process data

» Wonderware: NetDDE, FastDDE

» Rockwell Software: AdvanceDDE

8

OPC and the 5000 - Some History: 1992-95

• Windows 3.1 introduces OLE 2.0– based on COM, Microsoft’s

Component Object Model

– use of DDE now deprecated, because COM is» more flexible

» more robust

» more efficient (better transport mechanisms)

• Attempts begin to standardize uses ofOLE 2.0 and COM for process data

9

OPC and the 5000 - Some History: 1996-present

• Draft OPC Data Access specification launched 1995

• Formally released 1996

• Reached ‘critical mass’ by 1997

• OPC Alarms and Events released 1998

• Historical Data specification released 2001

OPC and the 5000 - An analogy

• cf. Windows printer drivers– Every printer has exactly one Windows driver,

which follows the standard driver model

– Every Windows program uses the standard printer driver model

• Result– Every Windows program can use any type of

printer

13

OPC and the 5000 - The OPC ideal

• Every piece of process or plant equipment has an OPC driver– the OPC server

• Every program which accesses plant data is capable of using OPC drivers– an OPC client

• Proprietary driver architectures are eliminated

14


• What is OPC?


• Who owns OPC

• Who uses OPC



15

OPC and the 5000 - Who owns OPC

• Original specification defined by the“OPC Task Force”– 5 process industry companies + Microsoft

– inc. Fisher-Rosemount, Intellution, Rockwell

• Now managed by the OPC Foundation– a not-for-profit industry grouping

– 300+ member companies

16


• What is OPC?


• Who owns OPC

• Who uses OPC



17

OPC and the 5000 - Who uses OPC

• Everyone!

• Supported by all leading SCADA software

• Drivers for every major PLC, every fieldbus standard, and most process equipment

• OPC Foundation member product catalog includes over 400 products

• Who owns OPC

OPC and the 5000 - Setting up the iTools OPC Server

• Current iTools release V4.21 has limitation of one IP address (hence one 5000) per port

• Ports configured via iTools Control Panel

• Who uses OPC



22

OPC and the 5000 - The future of iTools

• Faster startup of iTools OPC Server

• Next version of iTools (V5) will have port networks - each port can be assigned to one or more IP addresses

• Ports configured via iTools Control Panel

• Each Port can have unlimited number of IP addresses

• Multiple Ports can have duplicate IP addresses

• iTools OPC Server can automatically scan for IP addresses on the network

23


24


25


• iTools Out-Of-The-Box is optimised for configuring/commissioning small numbers of instruments

• For large networks, need to configure iTools OPC Server for “SCADA” mode - in EuroMBus (iTools OPC Server), under “Edit” menu, “Server Settings…”, select “Advanced” tab. Check the “Lean Server Mode”

26


• Further performance gains can be achieved by using the “Save As SCADA…” option under the “File” menu.

27


• iTools V5 will be packaged in a more modular way using the Microsoft Installer

• iTools V5 will have a new ordering code and pricing– Configuration Tools (replaces current Demo

edition)

– Open iTools OPC Server

– OPC Scope

– iTools Views

– Standalone Setpoint Programmer Editor

28

OPC and the 5000 - iTools Views

• PC-based user screens

• Editing environment - ‘iTools View Builder’– also used to create Configuration Wizards

• Visual editor for screen design

• Standard widget set– labels, edit fields, combo boxes, checkboxes, shapes,

bitmaps, ...

• Scripting language for enhanced interactivity– Visual Basic Scripting

• Data binding to any OPC server– special licensing for non-Eurotherm servers?
