The ActivityDataMonitoringType provides information about high-level logging of the activities performed on a laser system. This enables for example the tracking of configuration changes.

The ActivityDataMonitoringType is formally defined in Table 25.

The 4:Name is a human-readable string containing the name of the configuration parameter, that is being changed. The uniqueness of this name cannot be assumed. The value of this Property may change during its life cycle.

ParameterIdentifier is a unique string identifier for a configuration parameter. The mandatory identifier is to be used to provide a unique ID. The value of this Property does not change during its life cycle.

The PreviousValue Component represents the value of the configuration parameter before a change, it is optional and given as number.

The CurrentValue Component represents the now current value of the of the configuration parameter in question, it is mandatory and given as number.

The optional Description Component represents a human-readable description of the configuration change.

Note: The change time stamp is given by the source time stamp of the node.
