Program Structure
16
A total of 288 tasks with 288 programs can be created and controlled with the
CX-Programmer. These include up to 32 cyclic tasks and 256 interrupt tasks.
1. CJ1 CPU Units do not currently support I/O interrupt tasks and external in-
terrupt tasks. The maximum number of tasks for a CJ1 CPU Unit is thus
35, i.e., 32 cyclic tasks and 3 interrupt tasks. The total number of programs
that can be created and managed is also 35.
2. The CS1D CPU Units do not support any interrupt tasks. Interrupt tasks,
however, can be used as extra cyclic tasks with CS1D CPU Units.
Each program is allocated 1:1 to a task through individual program property
settings set with the CX-Programmer.

I/O refreshing
Peripheral processing
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.
Interrupt task 5
Condition Flags (ER, >, =, etc.) and instruction conditions
(interlock ON, etc.) are cleared at the beginning of each
task.
