Range 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 range 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 range allocation when the range data user-defined variables are
defined as follows.
c1D for Counter 1 (array[0..31] of _sCJCT021_Ex_RngLin) (Linear Counter, 32 ranges (maximum))
c2D for Counter 2 (array[0..31] of _sCJCT021_Ex_RngRing) (Circular Counter, 32 ranges (maxi-
mum))
