exclusive-ORed with the fixed polynomial value A001 (hex) prior to the next shift. Once all bytes of the
message have undergone the above algorithm, the CRC register will contain the message CRC value to
be placed in the error check field.
DECS-400 Modbus
™ Register Space
Modbus address space from 40000 to 49999 refers to function codes 3, 6, and 16. The DECS-400 uses
address space from 40001 to 44999 (4,999 registers). This address space is divided into 14 areas,
referred to as information categories.
Table 34 provides a statistical summary for each information category.
