Description
Right bit is least significant bit (0).
000 = BYTE used as an array of Boolean
001 = WORD used as an array of Boolean
010 = BYTE (8-bit integer)
011 = WORD (16-bit integer)
100 = DWORD (32-bit integer)
101 = TCHAR (8-bit (not unicode) or 16-bits (unicode))
110 = REAL (32-bit floating point value)
111 = Use bits 16, 17, 18
0 = unsigned
1 = signed
0 = visible
1 = hidden
0 = Parameter can sink a link
1 = Parameter cannot sink a link
0 = Recallable from NVS
1 = Not Recallable from NVS
0 = No ENUM text
1 = ENUM text
0 = Read only
1 = Read/write
0 = Writable when enabled (e.g., drive running)
1 = Not writable when enabled
0 = Parameter value is not a Reference to another
parameter
1 = Parameter value refers to another parameter
Must be zero
0000 = 0
