"Connect" modbus devices

[Stieges]

Hey guys.

Unfortunatlly i couldn't reach anybody at the manufacturer at the moment. I tried several settings but with noch luck. But i found something at the loxone library for that heat pump and they say this should work. 
I post you a snippet maybe you guys recognize the mistake i made.

Code:

<?xml version="1.0" encoding="UTF-8"?>
<Modbus Title="IDM Heat Pump" Comment="" Channel="1">
    <Info templateType="7" minVersion="12040628"/>
    <ModbusCmd Title="Überschuss" Comment="" ModbusAddress="74" ModbusCmd="16" ModbusDataType="36" ModbusPollingCycle="60" Unit="&lt;v.1&gt; kW" Analog="true" Sensor="false"/>
    <ModbusCmd Title="Überschuss" Comment="" ModbusAddress="74" ModbusCmd="4" ModbusDataType="36" ModbusPollingCycle="60" Unit="&lt;v.1&gt; kW" Analog="true" Sensor="true"/>
    <ModbusCmd Title="Leistung E-Heizstab" Comment="" ModbusAddress="76" ModbusCmd="16" ModbusDataType="36" ModbusPollingCycle="60" Unit="&lt;v.1&gt; kW" Analog="true" Sensor="false"/>
    <ModbusCmd Title="Leistung E-Heizstab" Comment="" ModbusAddress="76" ModbusCmd="4" ModbusDataType="36" ModbusPollingCycle="60" Unit="&lt;v.1&gt; kW" Analog="true" Sensor="true"/>
    <ModbusCmd Title="PV Leistung" Comment="" ModbusAddress="78" ModbusCmd="16" ModbusDataType="36" ModbusPollingCycle="60" Unit="&lt;v.1&gt; kW" Analog="true" Sensor="false"/>
    <ModbusCmd Title="PV Leistung" Comment="" ModbusAddress="78" ModbusCmd="4" ModbusDataType="36" ModbusPollingCycle="60" Unit="&lt;v.1&gt; kW" Analog="true" Sensor="true"/>

 For adress

Code:

  {
        "name": "Total DC Power",
        "bus_datatype": "float32",
        "datatype": "uint32",
        "type": "inputregister",
        "address": 5016,
        "units": "kW",
        "value_multiplier": 0.001,
        "read_swap": "n"
    },

78 i read the values like this:
