Allocating User-defined Variables
For the data used in Range Mode and Comparison Mode, it is necessary to allocate the variables used
by the user (user-defined variables) to memory for CJ-series Unit.
Structure data types are pre-defined for comparison data used in Range Mode and Comparison Mode.
In order to use these data types, register the structure data type for High-speed Counter Units before-
hand on the CPU/Expansion Racks screen in Configuration and Setup of Sysmac Studio.
With the Unit selected on the CPU/Expansion Racks screen in Configuration and Setup, right click, then
select Register Data Types for Units. The data type is registered and becomes usable.
The user program uses the user-defined variables to control High-speed Counter Units.
With High-speed Counter Units, the following structure data types can be used for each comparison
mode and Counter setting.
