This section provides an overview of the state machines and device status variables used in the LADS Companion Specification. It explains the relationship between various state machines and status variables in the context of a LADS Device, its Components, and Functional Units.

The relationship between these state machines and status variables is crucial for understanding the operation and management of a LADS Device. The state of the LADS Device state machine and the FunctionalUnit state machines come first and form the basis for the MachineryItemState. The MachineryOperationMode provides additional context about the type of Tasks being performed. The DeviceHealth and DeviceHealthAlarms provide information about the device's condition and any Alarms that may have been triggered.

Refer to Annex B for proposed mappings between the DeviceStateMachine, the FunctionalUnit state machines, the MachineryItemState and the DeviceHealth.
