EtherNet/IP

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.

Connection Properties

Endpoint Properties

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 response:

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