Overview

The HTTP interface can be used to integrate data and information from HTTP servers or other web services. The data exchange is bi-directional.

  • Retrieving data: using polling, data can be retrieved via HTTP GET, PUT and POST requests. The HTTP response may contain XML, JSON or normal text which can be parsed using XPath, JPath or Regex.

  • Updating data: via HTTP GET, PUT und POST requests, data including the server item value can be published to the foreign HTTP server. Again, XML, JSON or normal text content can be used.

The interface is available for free. Each defined HTTP data point is decreasing the available license data points by one.

Installation

The HTTP interface is provided as an extension and is not included within the default setup.

To install the HTTP interface, open the Core Studio and shutdown the Core Server. Afterwards, start the Extension Manager via the menu Extensions > Manager > Start Extension Manager ....

...

Within the dialog, select "HTTP" and press the Install button. After having installed the HTTP interface, close the Core studio and reopen it. Within the Core Studio you will find a new menu HTTP. It contains entries for all definitions that are necessary for configuration the HTTP interface.
