- MQTT Publisher
  The MQTT publisher provides a northbound data interface for MQTT clients to data point values within the WinCC OA project.
- Node-RED
  Node-RED is a flow-based programming tool that allows the creation of applications in a graphic environment.
- OPC UA Server
  The WinCC OA OPC UA Server provides an OPC UA interface to access WinCC OA datapoint values, alarms and historical data.
- OPC Server
  The OPC Server enables the communication with OPC clients.
- OPC HDA Server
  The WinCC OA OPC Historical Data Access (HDA) Server is used for the exchanging of archived process data of the WinCC OA project.
- OPC Alarms & Events
