Hi, i need a script written to extract data from a Codesys plc via a XML script and post them to a MQTT broker such as Amazon AWS or Google Cloud. A sample XML Symbol configuration code is below: "<?xml version="1.0" encoding="utf-8"?> <Symbolconfiguration xmlns="[login to view URL]"> <Header> <Version>3.5.7.0</Version> <SymbolConfigObject version="3.5.7.40" /> <ProjectInfo name="TemperatureMQTT_220121" devicename="Device" appname="APP" /> </Header> <TypeList> <TypeUserDef name="T_LIN_TRAFO" size="32" nativesize="36" typeclass="Userdef" pouclass="FUNCTION_BLOCK" iecname="LIN_TRAFO"> <UserDefElement iecname="IN" type="T_REAL" byteoffset="0" vartype="VAR_INPUT" /> <UserDefElement iecname="IN_MIN" type="T_REAL" byteoffset="4" vartype="VAR_INPUT" /> <UserDefElement iecname="IN_MAX" type="T_REAL" byteoffset="8" vartype="VAR_INPUT" /> <UserDefElement iecname="OUT_MIN" type="T_REAL" byteoffset="12" vartype="VAR_INPUT" /> <UserDefElement iecname="OUT_MAX" type="T_REAL" byteoffset="16" vartype="VAR_INPUT" /> <UserDefElement iecname="OUT" type="T_REAL" byteoffset="20" vartype="VAR_OUTPUT" /> <UserDefElement iecname="ERROR" type="T_BOOL" byteoffset="24" vartype="VAR_OUTPUT" /> <UserDefElement iecname="Diff" type="T_REAL" byteoffset="28" vartype="VAR" /> </TypeUserDef> <TypeSimple name="T_REAL" size="4" swapsize="4" typeclass="Real" iecname="REAL" /> <TypeSimple name="T_BOOL" size="1" swapsize="0" typeclass="Bool" iecname="BOOL" /> <TypeSimple name="T_UINT" size="2" swapsize="2" typeclass="UInt" iecname="UINT" /> </TypeList> <NodeList> <Node name="APP"> <Node name="PLC_PRG"> <Node name="fbiSensorScale" type="T_LIN_TRAFO" access="ReadWrite" /> <Node name="SensorInput" type="T_UINT" access="ReadWrite" /> <Node name="SensorMax" type="T_REAL" access="ReadWrite" /> <Node name="SensorMin" type="T_REAL" access="ReadWrite" /> <Node name="SensorOutput" type="T_REAL" access="ReadWrite" /> </Node> </Node> </NodeList> </Symbolconfiguration>" The raspberry pi will need to request the data from the PLC on an IP address (local address typically [login to view URL]) and then send the value from the tags to an MQTT broker. If a value on the Broker (Publish value) updates then the raspberry pi will need to send the updated value to the PLC. If anyone needs more details please ask me

Hi My robust knowledge and experience in MQTT broker and Python programing with RPI will allow me to tackle your project and deliver it to you in no time. I have built a pub/sub model with my local Mosquitto broker and paho-mqtt library. I am well aware of pub/sub workflow and the only thing for your project is to use cloud broker instead of local broker. Could you please share your details? Regards, Evgeny

Hello, I have a few questions regarding to your project environment: - the PLC is accessible from what connection: TCP, Serial, or Modbus? - the scripting would be in python or bash/shell? - is it raspberry Pi 4 or lower version? Let me know Khamid

Hi. Working with MQTT broker Amazon MQ and Node.js is my top skill and I have a lot of experience with it. Based on my rich experience, I can easily make a connection between your PLC -> Raspberry Pi 3/4 -> AWS MQ. Looking forward to hearing from you. Best regards.

Hi, I am an Embedded Engineer and Raspberry Pi Expert. I have done similar projects using MQTT and databases like AWS, Firebase, SQL etc. My most recent project was to fetch data from a machine using RS485 and post it to AWS...Need more information about your PLC ....Is it TCP/UDP based ? Leave massage for more details. Thanks

Hi, Do you have some preference for the programming language? Which protocol to utilize while fetching the data? Is the Codesys runtime also running on the Raspberry Pi or on an actual PLC?
