The components of the ControlModuleLiveStatusType are further described below.
|
BrowseName |
Description |
|
Alarms |
The Alarms folder provides alarms of the control module. |
|
ControlMode |
The ControlMode describes the current control mode of the equipment module. |
|
Data |
The Data folder contains additional data whose structure and name are not known in advance. |
|
Interlocks |
The Interlocks Folder provides the interlocks that, when not True, do not allow the operation of the control module. |
|
Measurements |
The Measurement Folder provides measurement values produced by the control module that do not require a dedicated process item e.g., actual motor current. |
|
ProcessControlLoops |
The ProcessControlLoops Folder contains regulation systems of the control module e.g., servo drives. |
|
State |
The State Property describes the status of the state machine controlling the control module. State provides a subset of the information of the state machine, when the latter is implemented. |
|
StateMachine |
The StateMachine describes the current state of the control module, the possible transitions, and their conditions. |
The components of the ControlModuleLiveStatusType have additional subcomponents which are defined in the following table.
