Hello! I use LMQTT Client Block (V 4.0.0) in TIA Portal V17 to send some data via MQTT protocol from the CPU 1510SP-1 PN to a MQTT broker. I have created all necessary configuration settings as it is described in the LMQTT Client Block Manual by SIEMENS. I am testing it with PLCSIM Advanced V4.0 SP1. But it doesn't work properly. The LMQTT_Client block status output jumps between 16#7003 and 16#9000 and doesn't want to switch to 16#7004 connected. I have checked it with two different brokers: Mosquitto and HiveMQ. But without any success. HiveMQ log:Client ID: SIEMENS, IP: 192.168.0.10 was disconnected. reason: Sent second CONNECT message. Mosquitto log: bad client SIEMENS sending multiple CONNECT messages The MQTT Explorer catches the Last Will message from the PLC correctly. IP PLC: 192.168.0.10; IP PLCSIM Virtual Adapter (and Brokers): 192.168.0.241 Anonymous Connections are allowed in the brokers conf. files. See attached zip-archive with the pictures. Please give me any idea what is going wrong. Thanks in advance. Best regards, Alexander. AttachmentMQTT_Prot.zip (337 Downloads) |
