MTConnect
The EMQX Neuron MTConnect driver accesses devices installed with MTConnect Agent through the HTTP protocol.
MTConnect is a read-only collection protocol: an MTConnect Agent exposes an HTTP read interface only, so this driver does not support writing back to the device.
For the generic steps, see Create a Southbound Driver and Groups and Tags.

ADDRESS
The driver address is in the form of XML XPATH.
node-name: Prefix
For self-closing tags where the value is represented by the element name (e.g., CONDITION-type data items), prepend node-name: to the address. When this prefix is used and the matched element has no child content, the driver extracts the element's tag name instead of its text content.
| Address Prefix | Behavior |
|---|---|
node-name: | Extract element tag name from self-closing tags. |
| (no prefix) | Extract element text content (default). |
Address Examples
| Address | Type | Des |
|---|---|---|
| //m:Angle[@dataItemId='Babs'] | float | Absolute angle of rotation axis B |
| //m:DeviceStream[@uuid='Mazak']/m:ComponentStream[@componentId='LYI1']/m:Samples/m:Position[@dataItemId='LYI1actm'] | double | Mechanical coordinates of linear axis Y |
| //m:DeviceStream[@uuid='Mazak']/m:ComponentStream[@componentId='Lct1']/m:Events/m:InputOutputSignal[@dataItemId='LPlcMonitorIO_1'] | bit | IO signal |
| node-name://m:*[@dataItemId='DMGlogic1'] | string | Element name of self-closing tag (e.g., Normal, Warning, Fault) |
