No valid sign-of-life tool
interface
Within the monitoring time of the tool interface
no valid sign-of-life has been received from the
tool interface.
Cyclically execute write tasks from the tool
interface within the monitoring time whereby
the sign-of-life has to be increased by 1 for
every write task.
