Extended Data Register (D) and Extended Link Register
(W)
The extended data register (D) and extended link register (W) are devices for utilizing the large-capacity file register
(ZR) area as an extended area of the data register (D) and link register (W). These devices can be programmed as the
data register (D) and link register (W) together with the file register (ZR) area.
Device numbers can be assigned to the data register
and extended data register consecutively.
Device numbers for the extended data register (D) and extended link register (W) can be consecutively assigned after
those for the internal user devices, data register (D) and link register (W). Note that even though device numbers are
consecutively assigned, there is no physical area contiguity between the data register (D) (internal user device) and
the extended data register (D), and between the link register (W) (internal user device) and the extended link register
(W). To use them as one contiguous area, set the points for the data register (D) and link register (W) (internal user
device) to "0" in the Device tab of the PLC Parameter dialog box, and use only the extended data register (D) and
extended link register (W).
When using the file register (ZR), extended data register (D) and extended link register (W) with the auto refresh setting for
the intelligent function module, the points set in the File register extended setting in the Device tab of the PLC Parameter
dialog box must not be exceeded.
