Web Connectivity / Network Interfaces
Data exchange, APIs and web technologies
- APIs
  An overview of the APIs (Application Programming Interface) available in WinCC OA.
- COM
  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.
- Prometheus Interface
  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.
- SIMATIC PLC Discovery
  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
- WinCC OA JavaScript Manager for Node.js
  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 (Augmented Reality)
  SIMATIC Unified AR is an industrial Augmented Reality app that allows to display and operate HMI screens (WinCC Unified) and web applications (WinCC OA Dashboard) in real production environments.
- HTTP Server
  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
  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.
- REST Reporting API
  The REST Reporting API is integrated into the Standard web server and can be activated via the config entry [restRporting] enabled.
- Distributed systems
  Distributed systems in WinCC OA allow to connect two or more autonomous WinCC OA systems via a network.
- Dist-Management
  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
  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.
User Management

Debug Flags


Debug Flag	Description
RRINFO	The REST Reporting API debug flag RRINFO logs values of read config entries, names of called endpoint-handlers, out-parameter names and values.
RRDETAILS	The REST Reporting API debug flag RRDETAILS logs JSON result/response of /reporting/GetVersion, internal function methods names and parameters (name and values), URL parameter names and values, information about used version of /reporting/DpNames.
RRJSON	The REST Reporting API debug flag RRJSON logs JSON result/response of /reporting/Dp, /reporting/Dps and /reporting/DpNames. This can be a lot of data (e.g. /DpNames: all DP names of the whole system).
RRSTRUCT	The REST Reporting API debug flag RRJSON logs native results of internal method calls.
