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):

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

Output Format on Write

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

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

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:

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

Output Format on Subscribe

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

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