Hello, If you are able to publish messages to the AWS server, then you should also be able to receive subscriptions. What topic has the SubMessage variable subscribed to on the AWS server? How are you publishing messages to this topic? Martin.

MySubTopic has the SubMessage subscribed to on the AWS server. This name is described in AWS IOT Client . “subscribe_data”:[{ “topic” : “MySubTopic”, “ports” :[ “Arp.Plc.Eclr/MainInstance.SubMessage” ] }] }] } but. I can’t read “Hello” at Arp.Plc.Eclr/MainInstance.SubMessage port in PLCnextEngineer
