Hello Emerson,
most probably there is no connection between your plc and the cloud server. To send data from a local PLC to the cloud, we strongly recommend an edge device that can add a layer of security and robustness.

P.S.: we kindly ask you to please post your questions in english, since it is the default forum language, to make it easier to share knowledge with people from all over the world
