Overview of G-language Programs in the MC Unit Section 1-7
Example 3: 2 Tasks and 4 Axes
Example 4: 1 Task and 2 Axes
The task configuration (axis configuration, number of tasks, and task axis
statements) is set by the unit parameters within the system parameters. (For
details, refer to
3-3 System Parameters .
Note The following table shows the factory settings for the task configuration (axis
configuration, number of tasks, and task axis statements). When using any
other task configuration, be sure to set these as the initial settings.
Default Task
Configuration
MC programs are managed according to the number of tasks, so it will be
necessary to rewrite the program if the task configuration is changed after the
program has been created. For details on changing the task configuration,
refer to
Section 3-2 Determining the Task Configuration .
Tasks and Blocks
The MC Unit is capable of storing a total of 2,000 blocks of programming. The
maximum number of blocks that can be executed in each task depends on the
number of tasks as shown in the following table. These figures include sub-
routines.
Note Up to 800 blocks can be used in one program, including subroutines.
Tasks and Programs
A maximum of 100 programs can be managed by the MC Unit. The number of
programs that can be managed per task depends on the number of tasks as
shown in the following table. These figures include subroutines.
Task 1 :
X, Y, Z axis Task 2:
U axis Task 1:
