Hello everyone, first time posting in the forum. I'm testing LMQTT library (https://support.industry.siemens.com/cs/ww/en/view/109780503) using a free cloud MQTT broker which uses TLS SNI security. The cloud brokers I've been using are: HiveMQ https://www.hivemq.com/ EMQX https://www.emqx.com/en I've looked for information about SNI (Server Name Indication) extension support in S71200 and 1500 PLCs, but all documentation just specifies TLS support. A technical rep from Siemens told me that TLS SNI extension is supported in S71500 PLCs but not in S71200. Still can't get LMQTT library running in S71500 PLC to connect to the cloud MQTT broker. Does some one know if TLS SNI Extension is in fact supported by Siemens PLCs? If it is, how is it enabled? Has some one connected to an MQTT broker that requires TLS SNI Extension using the LMQTT library ? Can you share details of what has to be done to enable SNI? TIA Portal V17 CPU 1212C DC7DC/DC v4.5 CPU 1515-2 PN v2.9 Tested with LMQTT v3.0.4 and 4.0.2 Thank you |

Hi! So that means MQTT over TLS won't work on my S7-1200 PLC? I have firmware v4.5, LMQTT v4.0.2, TIA portal v17. My PLC type is mentioned here as associated product (6ES7214-1AG40-0XB0) : https://support.industry.siemens.com/cs/cz/en/view/109780503 |
