Indexing
2) Index modification where the device number crosses over the boundary among the file register (ZR), extended
data register (D), and extended link register (W)
Index modification where the device number crosses over the boundary among the file register (ZR), extended
data register (D), and extended link register (W) will not cause an error.
However, an error occurs if the index modification result of file register (ZR), extended data register (D), and
extended link register exceeds the file register range (error code: 4101).
(5) Other index modifications
(a) Bit data
Device numbers can be index modified when performing digit designation. However, Indexing is not possible by
digit designation.
(b) Both I/O numbers and buffer memory number can be performed indexing with intelligent function module devices*
