Modbus Register Map (cont’d)
Format (R40,062)
This value determines the format of all unsigned, double-register integers (UINT32), except for
those in the direct parameter access.
0 indicates that the most significant byte (MSB) is given first
1 indicates that the least significant byte (LSB) is given first
