Agent

The MTConnect Agent receives data from one or more device Adapters and writes the data to an XML tree. This XML can be consumed by other applications, or displayed in a browser as an HTML webpage.

Run Image

The Agent comes with a recording of a CNC machine for playback.

This command will download an image of the Agent from Docker Hub (a central repository for Docker services) and run the simulation -

docker run -it --rm --init --name agent -p5000:5000 mtconnect/agent

View Output

View the output in your browser at http://localhost:5000 -

The Agent starts in the Probe tab, which shows the data items available - first for the Agent itself, then the CNC machine.

Click on the Current tab to see the current data values, then click on the Autorefresh button to have the view refreshed every 2 seconds.

The Sample tab shows a series of recent data values. The Agent comes with a buffer to store data values, and you can query it with XPath expressions.

For example, to see the last 10 values for the x-axis position, visit http://localhost:5000/sample?path=//Linear[@name=”X”]//DataItem[@type=”POSITION” and @subType=”ACTUAL”]&count=10
