--- title: MTConnect Ethernet slug: litmusedge/quickstart-guide/industrial-systems-connection-guide/mtconnect/mtconnect-ethernet description: Review the following information for setting up and configuring the MTConnect Ethernet driver. docTags: createdAt: 2026-10-14T18:20:42.984Z --- Review the following information for setting up and configuring the MTConnect Ethernet driver. The driver reads data from an MTConnect Agent over HTTP. At each polling interval, it requests the agent's `/current` document and serves tag values from that response. The driver is read-only. For the protocol reference, see the [MTConnect standard](https://docs.mtconnect.org/). :::hint{type="info"} **Note:** This driver is experimental. Some features might not work as expected. ::: # Litmus Edge compatible series | Compatibility parameter | Compatible items | | ---------------------------- | ---------------------------------------------------------------------------------------------------- | | **Driver type** | Ethernet (HTTP) | | **Validated devices/series** | Devices that support the [MTConnect](https://www.mtconnect.org/) standard through an MTConnect Agent | To set up and configure this device in Litmus Edge (LE), do the following: - Step 1: Set up and configure the device - Step 2: Set up the device in Litmus Edge DeviceHub - Step 3: Configure the list of registers # Step 1: Set up and configure the device Make sure the MTConnect Agent is running and that LE can reach it over the network. Record the following: - The IP address or hostname of the agent - The HTTP port of the agent - The name of the device in the agent, as it appears in the `name` attribute of the device stream. The name is case-sensitive. To check the device name, open `http://:/probe` in a browser. To try the driver with a public demo agent, see [Use the Mazak MTConnect Demo Agent to Connect a Device](docId\:bCkFjJ6gRTQ7Yl0EAVmQe). # Step 2: Set up the device in Litmus Edge DeviceHub Configure the following parameters when you [Connect a Device](docId\:pF5pwEP7Ata1NC7c0yQu_) with this driver. Update default values to the specific setup of your device. | Parameter | Value | | ------------------ | ----------------------------------------------------------------------------------------------------------------------------------- | | **Type** | MTConnect | | **Driver** | MTConnect Ethernet | | **NetworkAddress** | The IP address or hostname of the MTConnect Agent. Default value `192.168.0.1` | | **NetworkPort** | The HTTP port of the MTConnect Agent. Enter a value from `0` to `65535`. Default value `5000` | | **DeviceName** | The name of the device in the agent. The driver reads data only for this device. The name is case-sensitive. Default value `device` | The following parameter is under **Advanced Parameters**. | Parameter | Value | | ------------------ | ------------------------------------------------------------------------------------------------------------------------------ | | **RequestTimeout** | How long the driver waits for the agent to respond, in milliseconds. Enter a value from `500` to `30000`. Default value `3000` | For the **Meta Data**, **Status Register**, and **Optional Settings** options, see [Connect a Device](docId\:pF5pwEP7Ata1NC7c0yQu_). # Step 3: Configure the list of registers When you [Add a Tag](docId:89nruY50cZN0cPLIOmVdl) to the connected device, see the following sections. You can also [Browse and Add Tags from a Device](docId\:nZ8iGcvClQufkAB0i3s2a) for this device. Browsing reads the agent's `/probe` document. See the following additional resources if necessary: - [Organize Device and Tag Data by Using Metadata](docId\:gSM6iJPWjd0cCxWq2Qre2) - [Tag Formula Variables](docId\:Xj0OqYONxM2BEhMwqkDWC) ## Free tags This driver doesn't have a list of register names in the DeviceHub *Add Tag* form. Enter the data item in the form `.`. The driver matches the `name` attribute of the component and data item first. If an item has no name, use its ID instead. For example, `Controller.execution` or `path1.Fovr`. ## Available value types - `string` - `int` - `float` ## Tag parameters - **Name**: Enter the data item in the form `.`. See the *Free tags* section. - **Value Type**: Select a data type from the drop-down list. - **PollingInterval**: Enter how often the tag polls for data, in seconds. Enter `0` to disable polling. Default value `60` - **Tag Name**: Enter a name for the tag. - **Description** (Optional): Enter a description for the tag. - **Tag Formula**: Enter a formula for the tag to process the generated data. You can use two variables: `value` (current tag value) and `timestamp` (current tag UNIX time in milliseconds). The following math functions are available: - sin - cos - sqrt - tan - power: power(`x`) performs the operation `10^x`. - log: log(`x`) is the natural logarithm (the logarithm is in base `e`). - exp: exp(`x`) performs the operation `e^x`. - **Only Publish on Change of Value**: Select the checkbox to publish NATS messages only when the *value* parameter changes. *Change of Value* only applies to boolean, numeric (such as int or float), and simple string data types. It does not apply to complex types, such as JSON or array. Poll-once topics are not affected by *Change of Value* settings, and still receive a single message. - **Meta Data**: Define key-value pairs to add to the device output payload. :::hint{type="info"} **Note:** If you use special characters in metadata key names, the special characters are replaced with underscore characters in the payload. This can cause two key names to be combined into one. For example, configuring the key names a\*\*b and a&\&b creates only one key name (a\_\_b). :::
