End of support notice: On October 7th, 2026, AWS will discontinue support for AWS IoT Greengrass Version 1. After October 7th, 2026, you will no longer be able to access the AWS IoT Greengrass V1 resources. For more information, please visit [Migrate from AWS IoT Greengrass Version 1](https://docs.aws.amazon.com/greengrass/v2/developerguide/migrate-from-v1.html).
# IoT Ethernet IP Protocol Adapter connector
The IoT Ethernet IP Protocol Adapter [connector](connectors.md) collects data from local devices using the Ethernet/IP protocol. You can use this connector to collect data from multiple devices and publish it to a `StreamManager` message stream.
You can also use this connector with the IoT SiteWise connector and your IoT SiteWise gateway. Your gateway must supply the configuration for the connector. For more information, see [Configure an Ethernet/IP (EIP) source](http://docs.aws.amazon.com/iot-sitewise/latest/userguide/configure-eip-source.html) in the IoT SiteWise user guide.
**Note**
This connector runs in [No container](lambda-group-config.md#no-container-mode) isolation mode, so you can deploy it to a AWS IoT Greengrass group running in a Docker container.
This connector has the following versions.
| Version | ARN |
| --- | --- |
| 2 (recommended) | `arn:aws:greengrass:region::/connectors/IoTEIPProtocolAdaptor/versions/2` |
| 1 | `arn:aws:greengrass:region::/connectors/IoTEIPProtocolAdaptor/versions/1` |
For information about version changes, see the [Changelog](#ethernet-ip-connector-changelog).
## Requirements
This connector has the following requirements:
------
#### [ Version 1 and 2 ]
+ AWS IoT Greengrass Core software v1.10.2 or later.
+ Stream manager enabled on the AWS IoT Greengrass group.
+ Java 8 installed on the core device and added to the `PATH` environment variable.
+ A minimum of 256 MB additional RAM. This requirement is in addition to AWS IoT Greengrass Core memory requirements.
**Note**
This connector is available only in the following Regions:
cn-north-1
ap-southeast-1
ap-southeast-2
eu-central-1
eu-west-1
us-east-1
us-west-2
------
## Connector Parameters
This connector supports the following parameters:
`LocalStoragePath`
The directory on the AWS IoT Greengrass host that the IoT SiteWise connector can write persistent data to. The default directory is `/var/sitewise`.
Display name in the AWS IoT console: **Local storage path**
Required: `false`
Type: `string`
Valid pattern: `^\s*$|\/.`
`ProtocolAdapterConfiguration`
The set of Ethernet/IP collector configurations that the connector collect data from or connect to. This can be an empty list.
Display name in the AWS IoT console: **Protocol Adapter Configuration**
Required: `true`
Type: A well-formed JSON string that defines the set of supported feedback configurations.
The following is an example of a `ProtocolAdapterConfiguration`:
```
{
"sources": [
{
"type": "EIPSource",
"name": "TestSource",
"endpoint": {
"ipAddress": "52.89.2.42",
"port": 44818
},
"destination": {
"type": "StreamManager",
"streamName": "MyOutput_Stream",
"streamBufferSize": 10
},
"destinationPathPrefix": "EIPSource_Prefix",
"propertyGroups": [
{
"name": "DriveTemperatures",
"scanMode": {
"type": "POLL",
"rate": 10000
},
"tagPathDefinitions": [
{
"type": "EIPTagPath",
"path": "arrayREAL[0]",
"dstDataType": "double"
}
]
}
]
}
]
}
```
### Create Connector Example (AWS CLI)
The following CLI command creates a `ConnectorDefinition` with an initial version that contains the IoT Ethernet IP Protocol Adapter connector.
```
aws greengrass create-connector-definition --name MyGreengrassConnectors --initial-version
'{
"Connectors": [
{
"Id": "MyIoTEIPProtocolConnector",
"ConnectorArn": "arn:aws:greengrass:region::/connectors/IoTEIPProtocolAdaptor/versions/2",
"Parameters": {
"ProtocolAdaptorConfiguration": "{ \"sources\": [{ \"type\": \"EIPSource\", \"name\": \"Source1\", \"endpoint\": { \"ipAddress\": \"54.245.77.218\", \"port\": 44818 }, \"destinationPathPrefix\": \"EIPConnector_Prefix\", \"propertyGroups\": [{ \"name\": \"Values\", \"scanMode\": { \"type\": \"POLL\", \"rate\": 2000 }, \"tagPathDefinitions\": [{ \"type\": \"EIPTagPath\", \"path\": \"arrayREAL[0]\", \"dstDataType\": \"double\" }]}]}]}",
"LocalStoragePath": "/var/MyIoTEIPProtocolConnectorState"
}
}
]
}'
```
**Note**
The Lambda function in this connector has a [long-lived](lambda-functions.md#lambda-lifecycle) lifecycle.
## Input data
This connector doesn't accept MQTT messages as input data.
## Output data
This connector publishes data to `StreamManager`. You must configure the destination message stream. The output messages are of the following structure:
```
{
"alias": "string",
"messages": [
{
"name": "string",
"value": boolean|double|integer|string,
"timestamp": number,
"quality": "string"
}
]
}
```
