Description of Tasks Section 1-6
Each program is allocated 1:1 to a task through individual program property
settings set with the CX-Programmer.
Program Structure Standard subroutine programs can be created and allocated to tasks as
needed to create programs. This means that programs can be created in
modules (standard components) and that tasks can be debugged individually.
When creating modular programs, addresses can be specified by symbols to
facilitate standardization.
