Dear medea, Yes, optional encryption of messages via SSL/TLS is possible. Please refer to the document attached to this Application Example (page 8): Security function configuration To activate the security functionality of the connection, the related parameters declared in the Static of the instance DB of MQTT_Client FB must be set according to your specifications. Note: The security function configuration is not included in the scope of this document. For secured communication via SSL/TLS, please refer to the chapter 3.6 of "SIMATIC S7-1500, ET 200MP, ET 200SP, ET 200AL, ET 200pro Communication Function Manual" (https://support.industry.siemens.com/cs/document/59192925/). The information on the secured communication between MQTT broker and S7-1500 CPU via TLS can also be found in the chapter 2.3 of "MQTT Publisher for SIMATIC S7-1500" (https://support.industry.siemens.com/cs/document/109748872/) Best regards, Yu-wen

Dear Sistemi Zero, No, I don't. Instead, you can find the latest MQTT Publisher for SIMATIC CPU from Siemens Product Support website, which support the MQTT publisher function for S7-300. Best regards, Yu-wen |

Dear shadowofgod4343424, Error code W#16#80C4 comes from the TSEND_C and TRCV_C instructions. It's basically problem of TCP/IP connection which involves both MQTT broker and client sides and should be check first (please refer to this post). Best regards, Yu-wen |

@nguyenduchuu Same error info with me!!! Did you solve it? I am also using PLCSimAdv. And I am sure PLCSimAdv supports TSEND_C, and I already tested MQTT Publisher for SIMATIC CPU with PLCSimADV from here, it works!! https://support.industry.siemens.com/cs/cn/en/view/109748872 So I think (guess) the blocks from @Yu-wen Tang may have some bugs. I also hope @Yu-wen Tang can helps us out! |

The current MQTT Publisher link https://support.industry.siemens.com/cs/ww/de/view/109748872 shows the library supports both s7-1200 & 1500. Note that for secure messaging, the s7-1500 is required.
