Sharing Index and Data Registers between Tasks

Index and Data Registers (IR/DR) can be shared between tasks. The normal setting is for separate reg-
isters for each task. The current setting can be confirmed in A99.14.
Setting Method
Use the CX-Programmer to set shared index and data registers. This setting cannot be made from a
Programming Console.
1
Select a PLC in the CX-Programmer project tree and click the right mouse button.
2
Select Properties. The following PLC Properties Dialog Box will be displayed.
Leave the check mark for using IR/DR independently per task if separate index and data registers
are required for each task. Remove the check mark to use shared index and data registers for all
tasks.
