What is OPC?

*

What is OPC? - AcronymsOPC = OLE for Process ControlOLE = Object Linking & Embedding(Microsoft standard)OLE is based on COM technology

COM = Common Object Model

Microsoft renamed & enhanced COM into:DCOM = Distributed Common Object Model

DCOM is also used as the communication fundamentfor ActiveX

*

What is OPC? - Different standardsThe standards:OPC DAUsed to move real-time data from PLCs, DCSs, and other control devices to HMIs and other display clients.OPC HDAWhere OPC Data Access provides access to real-time, continually changing data, OPC Historical Data Access provides access to data already stored. From a simple serial data logging system to a complex SCADA system, historical archives can be retrieved in a uniform manner. OPC A&EProvides alarm and event notifications on demand (in contrast to the continuous data flow of Data Access). These include process alarms, operator actions, informational messages, and tracking/auditing messages. OPC DXThis specification takes us from client/server to server-to-server with communication across Ethernet fieldbus networks. And adds remote configuration, diagnostic and monitoring/management services.

OPC IOGate Client

*

OPC IOGate ClientI/A 8.0 does not support AW70 integrators, so IOGate is not supported on 8.0I/A 8.1 will support AW70 integrators.

Security considerations

*

OPC FBM SecurityGood security because:FBM separates OPC network and our control networkOnly CP's can talk to FBMs via fieldbusNo need for user accounts in FBMNo acces into control network via FBM

*

AIM OPC Server 1Box example1box approach BadAW70+AIMAPI+AIM OPC Server on one machineCentral point of failureOPC needs open ports to corporate network (DCOM)Needs constant maintenance and MS hotfix installation

*

AIM OPC Server 2Box example2box approach GoodAW70+AIMAPI on one machine, AIM OPC server on another machineAIM OPC Server is not an AW70Can put firewall in between AW70 and OPC, only AIMAPI needs to go through (port 45678)Customer can install MS hotfixes on OPC server
