Extended Data Register (D) And Extended Link Register (W) - Mitsubishi Electric Q01UCPU User Manual

4.8
Extended Data Register (D) and Extended Link Register
(W)
The extended data register (D) and extended link register (W) are devices for using 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)
Device numbers can be assigned to the
data register and extended data register
consecutively.

(1) Device numbers
Device numbers for the extended data register (D) and extended link register (W) can be assigned consecutively
after those for the internal user devices, data register (D) and link register (W).
● 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 the file register (ZR), extended data register (D), and extended link register (W) are used for auto refresh, set the
points so that they should not exceed those set in the "File Register Extended Setting" in the Device tab of the PLC
parameter dialog box.
Note 4.6
