What is OPC

OPC - OLE for Process Control,software interface standard that allows Windows/Linux programs to communicate with hardware devices and sensors. OPC is implemented in server/client pairs. OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is any program that needs to connect to the hardware, such as an HMI. The OPC client uses the OPC server to get data from or send commands to the hardware. The value of OPC is that it is an open standard, which means lower costs for manufacturers and more options for users. Hardware manufacturers need only provide a single OPC server for their devices to communicate with any OPC client. Software vendors simply include OPC client capabilities in their products and they become instantly compatible with thousands of hardware devices. Users can choose any OPC client software they need, resting assured that it will communicate seamlessly with their OPC-enabled hardware.

bullet j-Interop. Pure Java - COM Bridge.
Java provides a standard mechanism to access native methods\applications aptly named Java Native Interface or JNI, for short. Despite its many benefits JNI has certain drawbacks. Though JNI is Java, the developer still needs to know a lot more about the native component and the target architecture before accessing its services.

bullet Java/COM, Java/Win32 Integration resources
I use "Wire protocol products" to denote products that communicate between Java and Win32/COM via an out-of-proc mechanism. These systems can be 100% pure Java. "Proxy products" use JNI to build in-proc stub.

bullet OPC Software Products
OPC (formerly OLE for Process Control) is an industry standard created in collaboration with a number of worldwide leading automation hardware and software manufacturers. OPC allows software components such as software connectors to be combined and enables these components to intercommunicate without special adaptions. Further information on OPC can be found at: OPC Foundation and OPC Programmers' Connection.

bullet OPC Unified Architecture
The OPC-UA wrappers provide a migration path for the existing legacy products to become OPC-UA enabled providing a secure reliable interoperability across corporate firewall boundaries. The OPC-UA wrappers provide a migration path for the OPC COM/DCOM based specifications and products to the OPC unified architecture Web services platform. The side benefit is that the OPC unified architecture wrappers will also worked inside the corporate intranet providing secure reliable interoperability in that domain.

bullet Integrating OPC Data with Linux and QNX
An IT manager in a municipality office has created a live data link between a Lookout OPC server in Windows and a custom Linux application. He has an OPC DataHub connected to his OPC server, mirroring data to a Cascade DataHub running in Linux. On the Linux side, he feeds the data into an Oracle database, and from there into his custom application.

bullet Java2COM: Java and COM Integration
Java2COM is a bi-directional Java-COM bridging tool that enables Java applications, applets, and servlets to use COM objects and makes possible to expose Java objects as if they were COM objects.

bullet Linux DCE, CORBA and DCOM Guide
There is a rich selection of implementations of CORBA for Linux, including one that is focused on real-time operation, two more on fault-tolerance, and another two aimed at embedded systems. If these features are not important to you, but Microsoft's name is, then take a look at DCOM & ActiveX for Linux.

Advosol
The OPC-DA Client to XML-DA Server Gateway (XDAGW-CS) enables OPC DA client applications to access XML -DA servers. The XML-DA Gateway offers a way to allow existing OPC DA client applications access to remote servers and to upgrade step-by-step to web services technology.
The OPC XML-DA standard and the currently widely used OPC DA V2 standard address the same tasks but the server interface is quite different, due to their different base, web services respectively DCOM. Developers of OPC client applications have to be aware of these differences.
Technosoftware
The OPC Solutions from Technosoftware supports a wide range of operating systems like Windows, Windows CE.net, .NET, Linux, Sun SOLARIS and even QNX 6.3. With this Technosoftware shows its competence in software solutions and services for a wide range of operating systems. Fully functional FREE evaluation versions are available for download.

OPC brings XML-DA to the factory floor The Object Management Group (OMG) Automation World OPC Software Products
Two years ago, the OPC Foundation (http://opcfoundation.org) undertook the task of creating a new XML (eXtensible Markup Language) standard to augment its existing, widely successful COM/DCOM standards. OMGT is an international, open membership, not-for-profit computer industry consortium. OMG Task Forces develop enterprise integration standards for a wide range of technologies, and an even wider range of industries. Using Softing's XML-DA Linux Toolbox, a senior Design Team of the University of Idaho is developing an OPC XML-DA Client-based Web application to monitor a network of Synchrophasor devices. OPC (formerly OLE for Process Control) is an industry standard created in collaboration with a number of worldwide leading automation hardware and software manufacturers.

SCADA for Linux
SCADA is a software which allows to read current and historical data and events from the various devices types, to process the obtained data, to archive and save them in various DataBase, and also to display their for operator on symbolic circuit, trends, indicators and other graphic elements informing about technological process (HMI). The better the communication mechanism with drivers of various manufacturers is realised, the more universal is such a system.

Only few SCADA-packages support other than Windows operational systems. Basically, it is real time multitask OS Linux and QNX. The main reason of the choice of these OS is first of all the open source software (OSS).

For device communication in general, DCOM based OPC is the best choise, because you have the possibility to use modern technologies and new technology standart like OPC-UA and others.

In the Linux case, such rigid standards of communications as OPC or DDE do not exist, and the developers use their mechanisms of connection devices drivers, kernel and visualisation interface. You can read more detailed about alternatives OPC under Linux here.
