Start-up Behavior
At start-up, i.e., power-up or reset, all nvi's will be initialized
with INVALID, leading the actuator to drive to the configured
safety position after 1 minute.
Receive Heartbeat
The default configuration for “Receive Heartbeat” is 300 sec.
If no nvi update is received during this time, the field devices
will go to their configured safety positions.
