Hi. Have a good day everyone!. I had a problem when trying connect AWS broker with PLC S7-1500 using Public DNS Address . In new library LMQTT_Client , we can use both DNS or IP address broker to create connection. But i only connect successfully by using IP address it mean DNS not working . Follow document https://cache.industry.siemens.com/dl/files/872/109748872/att_994761/v2/109748872_MQTT_Client_DOKU_V2-0_en.pdf at page 10 we get: qdnsbrokerraddress: URL of the MQTT broker The URL must end with a dot ("."). So i copy DNS address broker to qdnsbrokeraddress with end dot. example: xxxx.amazonaws.com. but nothing happend. I try to ping DNS address and got no error , IP address is correct ( image attacked ) Please help me. I think i got incorrect dns format . Thanks you. |
