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