<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 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 15).

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 16.

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 22. 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 22 – 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 |

ChannelModifiers |
If an element of ChannelModifiers is True in any channel, it has to be True in the combined channel. |

FeedOverride is the combined actual feed override value that is effective for the manufacturing program of the machine tool.
PowerOnDuration is the duration the machine tool 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 tool and is not reset when the machine tool is power cycled.
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 tool adhering to such a standard, the OperationMode shall show the respective mode. For a machine tool 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 tool mode, it shall not be used in a safety relevant manner.
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.
The ChannelModifierType allows to show which modifiers are used while the machine tool is performing pre-production tests and similar tasks.
The ChannelModifierType is formally defined in Table 25.
