<MonitoredElement > is an optional Placeholder for ElementMonitoringType instances. This allows for any number of such instances as a component of the MonitoringType. For the DisplayName, it is recommended to use the value of the Name Property of the respective ElementMonitoringType instance.
MachineTool provides overall monitoring information of the machine tool.
Stacklight contains the information about a stacklight’s composition and status. It is an object of 4:BasicStacklightType, defined in OPC 10000-200. If the machine tool has a stacklight available, the Stacklight shall be present.
The optional 4:StackLevelType and 4:StackRunningType of the 4:BasicStacklightType shall not be used, only a segmented light shall be shown. Thus, the 4:StacklightMode of each stacklight has to be “Segmented” (0).
As 4:<StackElement>, only elements of 4:StackElementLightType shall be used. For these, the 4:SignalOn, 4:SignalColor and 4:SignalMode shall be used, not the 4:ControlChannelType (see Table 17).

The ElementMonitoringType is intended to be a supertype for all monitoring information that is specific to a particular element within the machine tool. An element doesn’t have to be a physical component. Examples for such elements are NC channels or spindles. It is an abstract type, meaning it is not instantiated, only the subtypes are.
The ElementMonitoringType is formally defined in Table 18.

ChannelState is representing the current status of the NC channel and is defined in 12.1.
ChannelMode is representing the current mode the NC channel operates in. It is defined in 12.2.
FeedOverride is representing the current value of the feed override of the NC channel.
RapidOverride is representing the current value of the rapid override of the NC channel.
ChannelModifiers is representing additional program modifiers usually used during special operations of the machine tool, e.g., preparation of production (see 8.3.10).
The CombinedChannelMonitoringType is a subtype of the ChannelMonitoringType and inherits all its InstanceDeclarations. Using this type instead of a ChannelMonitoringType provides an aggregated representation of the channels in a machine tool. The rules for aggregation are given in Table 24. Sometimes it is not necessary to provide one representation per individual channel, e.g., if one channel is of primary interest, the status of the remaining channels is irrelevant for the machine tool status. It could be used together with the separate channels. Typical applications are multi-spindle machines in which a large number of channels are used for interlinked work steps.
Table 24 – Rules for Aggregation of the CombinedChannelMonitoringType
|
Component of the CombinedChannelMonitoringType |
Rule for Aggregation |
|
ChannelState |
Mode of the channel not in “active”, otherwise “active” - if all channels active --> active - if >0 channel reset --> reset - else interrupted |
|
ChannelMode |
Mode of the channel not in “automatic”, otherwise “automatic” If one or more channel of the combined channels is not in “automatic” the machine tool is not producing (except if the channel is not currently in use). If for example the operator is in JogManual and moving one axis, the whole machine tool is not producing in automatic and the combined channel can be viewed as in JogManual |

FeedOverride is the combined actual feed override value that is effective for the manufacturing program of the machine tool.
IsWarmUp being True indicates if the machine tool is performing a warmup task. A warmup is not used for production, it is the mode used to reach a stable operating point for the machine tool. An example is reaching the optimal operating temperature. This might be indicated by a hardware switch on the machine tool, a special control command, a special production program (referenced by program name) or otherwise. In combination with the 3:MachineryItemState and the 3:MachineryOperationMode, the following behaviour is expected: If IsWarmUp is True, the 3:MachineryItemState is in state 3:Executing and the 3:MachineryOperationMode is in state 3:Setup.
3:MachineryItemState is used as defined in OPC 40001-1. Shall also be referenced as AddIn in the 3:MachineryBuildingBlocks folder.
3:MachineryOperationMode is used as defined in OPC 40001-1. Shall also be referenced as AddIn in the 3:MachineryBuildingBlocks folder.
MaintenanceMode, as a SubStateMachine of the 3:MachineryOperationMode (see Table 29), is only valid if the 0:CurrentState of 3:MachineryOperationMode is 3:Maintenance.
Obligation indicates the instance responsible for the current activities of the machine.
OperationMode contains a MachineOperationMode value as defined in 12.5. The values of the MachineOperationMode enum are derived from the MO modes of machinery functional safety standards. For a machine adhering to such a standard, the OperationMode shall show the respective mode. For a machine not adhering to such a standard, the OperationMode shall be filled with the appropriate mode available from the MachineOperationMode Enum. The OperationMode is only a representation of the machine mode, it shall not be used in a safety relevant manner.
[DEPRECATED in version 1.02] PowerOnDuration is the duration the machine has been powered, meaning all systems have line voltage. It is counted in full hours. This value only increases during the lifetime of the machine and is not reset when the machine is power cycled.
2:OperationCounters with 3:MachineryOperationCounterType is used as defined in OPC 40001-1. Shall also be referenced as AddIn in the 3:MachineryBuildingBlocks folder. It shall contain the 2:PowerOnDuration defined in OPC 40001-1.
2:OperationCounters optionally contains the counter PartsProducedInLifetime, which is the counter for the total number of produced parts during the machine’s lifetime. The exact way this number is acquired may differ between different machines. No quality information of PartsProducedInLifetime can be given.

The MaintenanceModeStateMachineType does not define an initial state.
The Service state indicates that measures to maintain or increase availability and duration of life are implemented. For example, linear guides are replaced, the bearings are lubricated, or the working area is cleaned.
The Inspection state indicates that the status is evaluated. For example, the lubrication is checked, the expendable parts are examined for wear and tear or the functionality of a workpiece holder is checked.
The Repair state indicates that the functionality of the unit is restored. For example, errors are fixed, or components are replaced.
The Upgrade state indicates that the performance, functionality, etc. of the unit are improved. For example, software upgrades, retrofitting of more powerful modules or modules with a longer duration of life.
The Other state is used if none of the other states apply.
The InstanceDeclarations of the MaintenanceModeStateMachineType have additional Attribute values defined in Table 33.

BlockSkip being True indicates that specially marked NC program blocks are skipped.
DryRun being True indicates that a test run using with a dedicated axis feed is being performed.
OptionalStop being True indicates that the execution will stop at special machine commands.
TestMode being True indicates a test mode which enables execution of a program without physical axis movement. The machining process may be simulated during program execution.
SingleStep being True indicates if the NC channel operates in single block/single step mode.
The ObligationType is used to indicate the entity responsible for the current activities of the machine. This value is needed for certain KPI standards.
The ObligationType is formally defined in Table 35.

EndUserObligated being True indicates that the machine‘s activity is the responsibility of the end user/operator.
MachineBuilderObligated being True indicates that the machine’s activity is the responsibility of the machine builder.
Typically, only one of EndUserObligated or MachineBuilderObligated is True, indicating the respective entity as responsible. Both being False indicates the obligation being unclear (e.g., unknown, third entity responsible). Both variables being True should not be used. It is foreseen that further obligation entities may be added in later versions; this way of representation allows for extension.
