11.2.1.2 Floating-Point word order (32-bit)
Non-volatHle regHster 402002/425346(0x07D1/0x6301) = 0t: HHgh word fHrst
If zero, when the register is set to be 0, the floating point high word is first in the Modbus
register.
Non-volatHle regHster 402002/425346(0x07D1/0x6301) <> 0t: Low word fHrst (Factory
Default)
If none-zero (factory default value), the floating point low word is first in the Modbus
register.
11.2.1.3 Fixed-Point word order (32-bit)
Non-volatHle regHster 402003/425347(0x07D2/0x6302) = 0t: HHgh word fHrst
If zero, when the register is set to be 0, the fixed point high word is first in the Modbus
register.
Non-volatHle regHster 402003/425347(0x07D2/0x6302) <> 0t: Low word fHrst (Factory
Default)
If none-zero (factory default value), the fixed point low word is first in the Modbus register.

11.3.1 Input status (discrete inputs)
Input status bits 101001 through 101032 may be available using function code 02. The status
definitions are defined the following table. The first 16 bits are the actual status state while
the late 16 bits indicate whether the corresponding status state is valid, or supported by the
trip unit.
