(2) 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 using the file register (ZR), extended data register (D) and extended link register (W) with the auto refresh setting
enabled in GX Configurator, the points set in the File register extended setting in the Device tab of the PLC parameter
dialog box must not be exceeded.
