<![CDATA[Little endian]]>Hi All,

how to set the data format "little endian" in mango?
I must put the variable in a meta data source?
If yes, what script should I enter?

thanks

I can do meta data source with a command like the following?

unsigned short int Endian_Word_Conversion(unsigned short int word) {
return ((word>>8)&0x00FF) | ((word<<8)&0xFF00) ;
}

where 'word' is, for example, p241.value or p241.other

any ideas?

thanks

The specifications of the device indicate that the protocol is Modbus RTU.
Very strange.

thanks

The Modbus spec - such as it is - is clear on byte ordering as i recall, and honestly, you're the first to ask for little endian. Why do you need it?

the protocol is Modbus.
So there is no chance?
I use the latest version of m2m mango.
If not, think that in future there will be?

thanks

the registers are transmitted as words of 16 bits, LSByte first, followed by MSByte.
How to do the reverse in mango?

thank you
