Allocation of User-defined Variables to the Memory Used for CJ-
series Unit
With this Unit, the slave areas of the following functions are allocated to the Memory used for CJ-series
Unit.
• Fixed allocations and user-set allocations (Master)
• Fixed allocations and user-set allocations (Slave)
The user program accesses the slave via the user-defined variable that specifies the AT specification
for the area where the slave is allocated. With this Unit, the device variable for CJ-series Unit, or a user-
defined variable that specifies the AT specification of the allocation area for the slave as setup using the
CX-Integrator software application, needs to be created. User-defined variables are created using Sys-
mac Studio.
Have the necessary user-defined variables created before creating a program.
For details on operations, refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504).
Precautions for Correct Use Precautions for Correct Use
The user is responsible for management of the memory used for CJ-series Unit. Please take
great care to avoid overlapping of reference areas between user-defined variables.
