Subroutines
Section 3-19
Examples
Example 1
When CIO 000000 is ON in the following example, global subroutine 1 is exe-
cuted and program execution returns to the next instruction after GSBS(750).
When CIO 000001 is ON in the following example, global subroutine 1 is exe-
cuted and program execution returns to the next instruction after GSBS(750).
Example 2
Two or more global subroutine programs can be programmed in interrupt task
0. In this case, interrupt task 0 can be divided and used as the subroutine
function’s task.
