and P3 are in an event task (execution priority: 48).
• P3 in the event task (execution priority: 48) is executed.
• The PrgStop instruction with P3 specified is executed in the event task (execution priority: 8).
• P3 in the event task (execution priority: 48) is disabled from the event task (execution priority: 48)
that is executed after the PrgStop instruction is executed.
• Thereafter, P3 remains disabled even if you do not execute the PrgStop instruction with P3 speci-
fied.
