Data servers are modules that “serve” data from the VisXpert variables to other applications. This allows other applications to connect to VisXpert and extract data via various formats. Data Servers are implemented as Modules and can be added to the project as required. Servers do not produce data, but allow their clients to have access to the VisXpert variables via the specific interface and protocol.
Some Servers will need an “Mapping” table to allow clients to access the VisXpert variables. This “mapping must be created before the Server becomes usable. Other Servers, such as OPC-UA or DDE, Directly allow access without mapping Tables.
Currently the following Servers are available:
- Modbus TCP
- OPC-UA
- DDE (dynamic data exchange) mainly for Excel real time data access
- MQTT
