Operation: Automatic reintegration
Operation in the following table shows the procedure:
■ Simulating a wire-break at the emergency stop button.
■ Passivation of the entire F-DI
■ Automatic reintegration after removing the wire-break
A more detailed description of the scenario, with overview image
on the hardware setup, is available at page 330.

At page 334 you find an overview of statuses and mode transitions
of the sample code. The area in the figure marked as
"Automatic reintegration of F-DI" is relevant here.

the TEST and ACTUATOR indicator
lights are switched off.
