- 89 10.8 Extended Data Register (D) and Extended Link Register (W)
6) To access the extended data register (D) or extended link register (W) from a
module which does not support the use of those devices, device number
needs to be specified by that of the file register (ZR).
Calculation formulas to obtain device number of the file register (ZR) to be
specified to access the extended data register (D) or extended link register
(W) and their calculation examples are described below.
register (D) or extended link register (W)
Item
* 1: Variables in the table above indicate the following.
• ZR : Number of points set for the file register (ZR)
C
• ED : Device number of the file register (ZR) to access the extended data register (D)
ZN
• ED : Access target device number of the extended data register (D)
N
• D : Number of points set for the data register (D)
C
• ED : Number of points set for the extended data register (D)
C
• EW : Device number of the file register (ZR) to access the extended link register (W)
ZN
• EW : Access target device number of the extended link register (W) (hexadecimal)
N
• W : Number of points set for the link register (W)
C
[Calculation example]
• D : Number of points set for the data register (D) ••• 12288 points
C
• W : Number of points set for the link register (W) ••• 8192 points
C
• ZR : Number of points set for the file register (ZR) ••• 2048 points
C
• ED : Number of points set for the extended data register (D)
C
••• 2048 points
