Raspberry pi script to read codesys symbols and post them to MQTT broker

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]">



<SymbolConfigObject version="" />

<ProjectInfo name="TemperatureMQTT_220121" devicename="Device" appname="APP" />



<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" />


<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" />



<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" />





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
