XML device configuration

XML device configuration defines slave address, registers (holding / input registers) and discretes (coils and statuses). For transaction optimization registers and discretes can be grouped.

Device configuration example

<!DOCTYPE mbm>
<Device version="2.0" Slave="1" Name="PZT2" >
    <Register Format="int16" Digits="15" Update="false" Name="Target" Addr="0" />
    <Register Format="int16" Digits="5" Update="false" Name="Target (V)" Addr="1" />
    <InputRegister Format="uint16" Digits="0" Update="true" Name="Status" Addr="0" />
    <InputRegister Format="int16" Digits="15" Update="true" Name="Voltage" Addr="1" />
    <InputRegister Format="int16" Digits="5" Update="true" Name="Voltage (V)" Addr="2" />
    <InputRegister Format="uint16" Digits="16" Update="true" Name="PD" Addr="3" />
    <Group Update="true" Name="ADC" Addr="4" >
        <InputRegister Format="uint16" Digits="0" Name="Ch2" />
        <InputRegister Format="uint16" Digits="0" Name="Ch3" />
        <InputRegister Format="uint16" Digits="0" Name="1v1" />
        <InputRegister Format="uint16" Digits="0" Name="Gnd" />
    </Group>
</Device>
