Block Run of Task

4-3-5 I/O Break Condition Setting

110
When debugging only a specific rung, set a start point at the top of the rung
and a break point at the top of the next rung (shown by the hatching in the
diagram) to execute the specified range of the rung.
However, when repeating executing a specific rung continuously, reset a start
point, which is automatically cleared on execution, after stopping at the break
point.

When the Ladder Engine is in stop (the Program mode), if a task is executed
from the pop-up menu after selecting the task in the [Task Control], Step Run
will be executed with a start point set at the top of the task and a break point at
the bottom of the task automatically. (While the program is being executed, an
interrupt will occur at the timings: when a task execution flag is set for a Cyclic
Task and when the interruption occurs for an interrupt task.)
Note In the Block Run, the following operation will be performed after stopped by an
End instruction:
(1) For a cycle task, the next executable task is executed,
(2) For an interrupt task, a cyclic task in the next cycle is executed.
The setting expression of I/O break condition is a logic expression combining
multiple I/O break conditions. If an I/O break condition is set, the I/O break
pauses the program execution when the contents of the I/O memory area get
to satisfy the specified condition. Only one condition can be set for the setting
expression.
