3.3 Indexing
4) Usable range of index registers
The following table shows the usable range of index registers in 32-bit indexing used “ZZ” specification.
The 32-bit indexing with “ZZ” specification is specified as the format ZRmZZn.
Specifying ZRmZZn enables Zn and Zn+1 of 32-bit values to index the device number, ZRm,
5) The 32-bit indexing used “ZZ” specification and the acutual processing device are as follows.
(Z0 (32-bit) 100000.Z2 (16-bit) -20)
Fig.3.10 Ladder Example and Actual Process Device
6) Available functions for “ZZ” specification
The 32-bit indexing specification with “ZZ” specification applies in the following functions.
ZZn cannot be used alone as a device like “DMOV K100000 ZZ0”. When setting values of index registers to specify 32-bit
indexing with “ZZ” specification, set the value of Zn (Z0~Z19).
ZZn alone cannot be input to each function.
