This extension is provided by True Analytics Manufacturing Solutions (TAMS). .mep is currently a proposed/experimental exchange format and is not an approved MTConnect specification. This package is not an official feature of the MTConnect Institute Reference Agent.

From raw XML to an Agent workspace

See the progression from raw MTConnect XML through legacy and open-source styles to the TAMS interface, with device navigation, filters, and MEP export.

Raw XML, legacy styles, open-source styles, and TAMS v0.1.1 are shown in sequence. The TAMS view includes Probe, Current, Sample, and Export MEP controls.

Export a capture. Explore the evidence.

With the TAMS extension installed on your Reference Agent, export a .mep file and open it in MEP Explorer.

The recording follows Export MEP in the Agent, then opens the package in MEP Explorer to inspect capture coverage, execution states, and the exact state breakdown. Processing time varies by package.

Try MEP Explorer with an approved example or your own capture.

Read the results with their context

Capture span, observed items, and state durations answer different questions. MEP Explorer keeps those distinctions visible.

MakerBot capture: 3 hours 27 minutes 7 seconds; 31 of 31 items seen. Execution was READY for 99.99% of the interval, with 0.01% unknown and no observed ACTIVE duration.
This capture observed every configured item at least once. Its execution state was almost entirely READY; this is not an uptime measurement. Unknown coverage remains explicit. Select the image to view it at full size.

Export, share, and explore

Add the TAMS style extension to your Reference Agent to export an experimental MEP package. Use it to explore manufacturing data, share a capture, or test an MTConnect implementation.

The ZIP includes the style files, installation instructions, license notices, and synthetic MEP examples.

What gets exported?

  • The MTConnect device model and snapshot or retained-buffer observations.
  • Package and provenance metadata, plus integrity hashes.
  • Agent validation evidence when available; this does not establish conformance.

The exporter does not collect TAMS dashboard configuration or Agent configuration files. Agent responses may themselves contain sensitive values; review the package before sharing.

The extension constructs the package in your browser using responses from your Agent, without sending Agent data to TAMS. If you choose to upload the package to MEP Explorer, it is sent to the Explorer analysis service for processing.

Installation overview

  1. Back up your installed Agent styles.
  2. Copy all seven active files from the ZIP's styles folder together into the Agent's served styles folder. Do not deploy the examples or replace machine settings.
  3. Follow the included README.md for the styles mapping, image MIME types, and configuration paths. Configuration changes may require a coordinated restart.
  4. Hard reload Probe, Current, and Sample, then try Export MEP. Restore the backed-up files if needed.

After exporting, open your package in MEP Explorer.
