Invoke Service¶

The Invoke Service node controls the invoke service downstream message to Kafka.

Note

This does not automatically invoke the service of the device; to do this, use the Send Command node instead.
If there is custom processing done on the invoke service message, not using the Invoke Service node will result in the failure to send the message to Kafka, which will cause the device to be unable to receive any control commands.

Node Type¶

EnOS.

Input and Output Ability¶

This node has multiple entry points and 2 exit points (success/failure).

Node Properties¶

Name
