Data exchange, APIs and web technologies
COM - Microsoft Interface stands for Component Object Model, a specification for developing modular software components which can be used by each COM compatible application. COM components can be easily integrated in such applications and can even be removed from an application at run time. COM components can be programmed in various different programming languages although C++ is used mostly. The specifications OLE, ActiveX and DirectX are based on the COM technology.

An overview of the APIs (Application Programming Interface) available in WinCC OA.
The Manager Service API (MSA) is the backbone for seamless, protocol-independent communication and logic reuse between WinCC OA managers, supporting modern distributed and web-integrated SCADA architectures.
The Prometheus interface (also referred to as Prometheus client) serves as a bridge between WinCC OA and Prometheus. It facilitates the retrieval, processing, and exposure of data from the WinCC OA system to a Prometheus-compatible format. This allows Prometheus to monitor and alert based on the data fetched from the WinCC OA system.
In increasingly dynamic automation environments and the merging of IT with OT, the SIMATIC PLC Discovery can help with the connection of newly added S7/S7+ devices by showing you all the devices in the network
The WinCC OA JavaScript Manager for Node.js is a manager that allows for the integration of the TypeScript/JavaScript runtime environment Node.js into WinCC OA.
SIMATIC Unified AR is an industrial Augmented Reality app that allows to display and operate HMI screens (WinCC Unified / WinCC V8) and web applications (WinCC OA Dashboard) in real production environments.
webserver.js is a Node.js-based web server that provides a modern, extensible backend for full-stack web applications in WinCC OA.
The HTTP Server integrates Internet technologies directly into WinCC OA . Implemented as an add-on for the Control Manager, possible applications are many and diverse. The HTTP Server can be used as a web server for static HTML pages including download facility or to generate dynamic HTML pages.
XML-RPC (Extensible Markup Language Remote Procedure Call) allows software on different operating systems to make procedure calls over the internet. XML-RPC uses HTTP for the transport and XML for the encoding. It sends the procedure call to a remote server through HTTP. The call is an XML document and it receives the response as XML.
The REST Reporting API is integrated into the Standard web server and can be activated via the config entry [restRporting] enabled.
Distributed systems in WinCC OA allow to connect two or more autonomous WinCC OA systems via a network.
Configuring and maintaining a distributed system in WinCC OA requires a high amount of engineering effort due to a high number of settings and configuration steps that must be applied on several systems. The Dist-Management reduces the engineering effort and simplifies the necessary settings.
XMPP (formerly Jabber) is mostly used in chat (instant messaging) applications and allows near real time communication between two or more parties. It can, e.g., be used to push information from a WinCC_OA project server to one or more persons, even allowing the recipient to send a confirmation back to the server.
