Word Order
Word Order controls the order in which Multifunction Meter receives or sends
floating - point numbers:- normal or reversed register order . In normal mode, the

first. In reversed register mode , the two registers that make up a floating point
numbers are sent least significant bytes first. To set the mode, write the value ‘
2141.0’ into this register-the instrument will detect the order used to send this value
and set that order for all ModBus transaction involving floating point numbers.
