(3) 32-bit index setting (for Universal model QCPU only)
Either of the following two methods can be selected to specify index registers used for a 32-
bit index setting.
• Specify a range of index registers used for a 32-bit index setting.
• Specify a 32-bit index setting using 'ZZ'.
32-bit index settings using 'ZZ' can be used for the following CPU modules only.
• QnU(D)(H)CPU with a serial number whose first five digits are '10042' or higher
• QnUDE(H)CPU
(a) Specifying a range of index registers used for a 32-bit index setting
1) Values from 2147483648 to 2147483647 can be set to index registers.
The following shows how the index is set.
2) Specification method
When setting indexes in 32-bit range, specify the start number of index
registers to be used in the device setting of the PLC parameter in GX Works2.
Figure 3.7-2 Index setting for ZR device on the parameter setting screen
When changing the start number of index registers to be used in the device
setting of the PLC parameter, do not change nor write only parameters to the
programmable controller. Always write parameters along with the program to the
programmable controller.
If data are forcibly written, the operation error "CAN'T EXE. PRG." (error code:
2500) occurs.
