3.3 Indexing
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 in GX Developer.
Single ZZn cannot be used 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).
Single ZZAn cannot be input to each function in GX Develoiper.
