mtconnect-node's Introduction

MTConnect-Node

An implementation of an MTConnect agent on NodeJS

What's New

This project has been migrated over to Typescript, and may now be built in the Visual Studio Code editor with Ctrl+Shift+B. XPath queries partly work. No error returned for invalid XPath, and all tags must be prefixed with an 'm:' namespace. DataItem update is now handled through POST, using a method similar to the cppagent.

All previous readme entries have been moved to release-notes.md.

Known issues

Assets are not implemented at all. Interval parameters are not supported. The agent will not return an error document for several very basic error conditions. All of the XML documents lack proper xmlns namespace attributes. Test cases are not yet created.

Installation

  1. Install Node.js.
  2. Obtain the MTConnect-Node repository.
  3. (Optional) Modify the included probe.xml file, which was taken from the MTConnect Institute Agent.

Usage

Running the Agent

From a command prompt in the repository working directory: $ npm start

All configuration is handled in conf/agent.json, but configuration is minimal at the moment.

mtconnect-node's Issues

Support MTConnectStreams requests

Support streams requests (current, sample), including parameter support.

Current request allows parameters path, at, interval.
Sample request allows parameters path, from, count, interval.

No support for MTConnect assets

No support currently exists for MTConnect assets or cutting tools, which have been present since version 1.2 of the spec.

XML document formatting

XML documents produced by the agent are missing XML declarations, and xmlns namespace attributes.

Support PUT-style item updates

Allow updates to items via HTTP PUT/POST. Necessary because MTConnect adapters are not yet supported, so otherwise there would be no way to update data items.

Should try to accept same form-data format as the cppagent.
