Comparison data are set in the user-defined variable. Refer to "Allocation to User-defined Variable"
(P. 4-10) for more information.
Two types of structure data are prepared beforehand for comparison data user-defined variables: one
type for Linear Counters and one type for Circular Counters.
Register the structure data type for High-speed Counter Units beforehand 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.
Use these structures to define user-defined variables.
The table below shows an example of comparison data allocation when the comparison data user-
defined variables are defined as follows.
c1D for Counter 1 (array[0..31] of _sCJCT021_Ex_CmpLin)
(Linear Counter, 32 comparison data (maximum))
c2D for Counter 2 (array[0..31] of _sCJCT021_Ex_CmpRing)
(Circular Counter, 32 comparison data (maximum))
