The region block starting with "< Sett i ng >" and ending with "</Sett i ng >" is a "constant value recording block". Wherein, the mark is 16 bi t bit, and the output is carried out according to 16 system (format is 010B), the high 8 bit corresponds to the 'group No' (definite value group number) of the belonged group, the corresponding relation with the group in the 'definite value group block' can be obtained, the low 8 bit corresponds to the concrete item number; the value type is the M type code, see table below; the value, the maximum value, and the minimum value are displayed according to the value type.
The region blocks ending with "< Sett i ngVa l Zone1 >" to "< Sett i ngVa l Zone32 >" are "respective partition value recording blocks". When the device has a plurality of constant value areas, the constant values of all the constant value areas are sent by the segment, and if the device does not have a plurality of constant value areas, the segment does not need to be sent.
The last line represents the CRC check code of the file content in a comment form, the CRC32 is a check result code obtained by performing CRC32 check after removing the line feed symbol in addition to the last line comment line.
