# EtherNet/IP

Connect Connectware to factory and process devices via EtherNet/IP, the Common Industrial Protocol (CIP) on standard Ethernet.

EtherNet/IP is an industrial network protocol that adapts the Common Industrial Protocol to standard Ethernet. EtherNet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries including factory, hybrid and process.

### Input Format on Write

When writing data, a JSON object with the following structure should be sent to a write endpoint (`/set`):

{% code lineNumbers="true" %}

```json
{ "id": "<correlation id>", "value": "<value>" }
```

{% endcode %}

### Output Format on Write

When writing data, the result of the operation will be published to a `/res` topic with the following structure:

{% code lineNumbers="true" %}

```json
{ "id": "<correlation id>", "timestamp": "<msSinceEpoch>", "result": "<result>" }
```

{% endcode %}

### Output Format on Read

When data is read from a read endpoint (`/req`), the following JSON is returned as a response in a `/res` topic:

{% code lineNumbers="true" %}

```json
{ "id": "<correlation id>", "timestamp": "<msSinceEpoch>", "value": "<value>" }
```

{% endcode %}

### Output Format on Subscribe

When data is read by means of a subscription endpoint, the following JSON is returned as a response:

{% code lineNumbers="true" %}

```json
{ "id": "<correlation id>", "timestamp": "<msSinceEpoch>", "oldValue": "<old value>", "value": "<value>" }
```

{% endcode %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.cybus.io/2-6-1/connectors/shop-floor-connectors/ethernet-ip.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
