Hello im using a serial protocol and i need o calculate the length of some parte of message to send it as ascii, it is working but the size is inverter.

                 <Param id="40">
                        <Name>interval_command_len</Name>
			<Description>interval_command_len</Description>
			<Type>length</Type>
			<Interprete>
				  <RawType>numeric text</RawType>
				  <LengthType>fixed</LengthType>
				  <Length>4</Length>
				  <Type>double</Type>
			</Interprete>
			<Length>
				<Content>
					<Param>5</Param>
					<Param>6</Param>
					<Param>7</Param>
				</Content>
			</Length>
		</Param>

		<Command id="5007">
			<Name>Set GPS Config Command</Name>
			<Description>Set GPS Config Command</Description>
			<Content>
				<Param>2</Param>
				<Param>39</Param>
				<Param>39</Param>
				<Param>40</Param>
				<Param>39</Param>
				<Param>41</Param>
				<Param>38</Param>
				<Param>4227</Param>
				<Param>23</Param>
			</Content>
		</Command>

                <Trigger id="5006">
			<Name>before_timecomand_Command</Name>
			<On id="5007">command</On>
			<Time>before</Time>
			<Type>action</Type>
			<Content>
				<Id>1</Id>    <--makecommand-->
				<Id>5006</Id>
			</Content>
		</Trigger>

                <Action id="5006">
			<Name>GetCommandLeng</Name>
			<On>command</On>
			<Type>length</Type>
		</Action>

The size is calculated but should by "000x" format, also and Endian in action but the response was 0001 for 10 size

                 <img src="https://community.dataminer.services/wp-content/uploads/anspress-temp/f46317f4bbf69b198e38d41f9cf06a6ad6aef4d0_1668.png" />

Its posible calculate the correct format or have to use a qaction?
Thanks
