: Link variable for BYTE data format (1 byte)
Data type:
Range of values:
: Link variable for WORD data format (2 bytes)
Data type:
Range of values:
: Link variable for DWORD data format (4 bytes)
Data type:
Range of values:
: Link variable for REAL data format (8 bytes)
Data type:
Range of values:
: Address index in bytes, counted from the start of the link variable memory
Data type:
Range of values:
UINT
0 to 255
INT
-32768 to 32767
INT
-2147483648 to 2147483647
REAL
±(2,2*10 ... 1,8*10
-308 +308
INT
0 - MAX_INDEX
Note
• MAX_INDEX is calculated from the parameterized
size of the link variables memory: MAX_INDEX =
(MD18700 $MN_MM_SIZEOF_LINKVAR_DATA) - 1
• Only indices may be programmed, so that the bytes
addressed in the link variables memory are located on
a data format limit ⇒
Index = n * bytes, where n = 0, 1, 2, etc.
