QueryEventCategories | Finds out events categories supported by the server. The QueryEventCategories method gives clients a means of finding out the specific categories of events supported by a given server. This method would typically be invoked prior to specifying an event filter. Servers are able to define their own custom event categories, but a list of recommended categories is provided in the OPC specification. Server descriptor is used for specifying the OPC server. Queries event categories for given event types. (Inherited from OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClientCore) | |

ReadXml | (Inherited from OpcLabs.BaseLib.Widgets.Widget) | |
RefreshEventSubscription | Force a refresh for all active conditions and inactive, unacknowledged conditions whose event notifications match the filter of the event subscription. Clients often need to get the current condition information from the server, particularly at client startup, for things such as a current alarm summary. The OPC Event Server supports this requirement by resending the most recent event notifications which satisfy the filter in the event subscription and which are related to active and/or unacknowledged conditions. The client can then derive the current condition status from the "refreshed" event notifications. (Inherited from OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClientCore) | |
Reset | Sets the object properties back to their defaults. (Inherited from OpcLabs.EasyOpc.AlarmsAndEvents.EasyAEClientCore) | |

WriteXml | (Inherited from OpcLabs.BaseLib.Widgets.Widget) |
Name | Description | |
---|---|---|
AcknowledgeCondition | Overloaded. Acknowledges a condition in the Event Server. The client will receive event notifications (indicating the acknowledgement) from conditions. This method specifically acknowledges the condition becoming active or transitioning into a different sub-condition (and no other state transition of the condition). One or more conditions belong to a specific event source - the source of the event notification. For each condition-related event notification, the corresponding Source, Condition Name, Active Time and Cookie is received by the client as part of the event notification.
The client is required to pass the activeTime and cookie received in the event notification to the AcknowledgeCondition method without modification. The server(s) can be local or can be remotely accessed via DCOM.
| |
AcknowledgeMultipleConditions | Acknowledges multiple conditions in the Event Server. | |
BrowseAreas | Overloaded. Browses the specified area (or root) in OPC server's process area space, and returns information about child areas found.
| |
BrowseNodes | Overloaded. Browses the specified area (or root) in OPC server's process area space, and returns information about child nodes (areas or sources) found. | |
BrowseOne | Browses the nodes in OPC A&E server's address space. Starts from the specified node, and returns information about child nodes found. Browses the nodes in server's address space, given a browse arguments object. | |
BrowseServers | Overloaded. Browses for OPC (Alarms&Events) servers.
| |
BrowseSources | Overloaded. Browses the specified area (or root) in OPC server's process area space, and returns information about child sources found.
| |
BrowseTree | Overloaded. Allows to traverse through OPC A&E address space nodes under the specified node, using given browse arguments. | |
ChangeEventSubscription | Overloaded. Changes parameters of a particular event subscription.
| |
FindEventCategory | Attempts to find a specified event category in the OPC server, and returns information about it when found. | |
FindEventCondition | Attempts to find a specified event condition in the OPC server and for given event category, and returns information about it when found. | |
GetConditionState | Overloaded. Returns the current state information for the condition instance corresponding to the source and condition name.
Some servers may not maintain sufficient condition state information to fully implement this method. The server(s) can be local or can be remotely accessed via DCOM.
| |
PullNotification | Attempts to pull an OPC event subscribed to by the IEasyAEClient.SubscribeEvents method. Returns refresh or standard event notifications. | |
QueryCategoryAttributes | Overloaded. Finds out event attributes that the server can provide as part of an event notification within a given event category. Uses server descriptor for specifying the OPC server. | |
QueryCategoryConditions | Overloaded. Finds out event conditions supported by given event category. Uses server descriptor for specifying the OPC server. | |
QueryEventCategories | Overloaded. The QueryEventCategories method gives clients a means of finding out the specific categories of events supported by a given server. This method would typically be invoked prior to specifying an event filter. Servers are able to define their own custom event categories, but a list of recommended categories is provided in the OPC specification.
| |
QuerySourceConditions | Finds out event conditions associated with the specified source name. Computer name and server class are used for specifying the OPC server. | |
SetState<TNode> | Sets the arbitrary object associated with the node. | |
SubscribeEvents | Overloaded. Subscribe to particular OPC events. The IEasyAEClient.Notification is generated for each event.
| |
SubscribeMultipleEvents | Overloaded. Subscribe to multiple OPC events. The size of the input array will become the size of the output array. The element positions (indices) in the output array are the same as in the input array. The function returns an array of integer handles. Each such handle uniquely identifies the events subscription. The indices of elements in the output array are the same as those in the input array. | |
SupportsTechnology | Determines whether the client object supports a given OPC technology or technologies (such as OPC COM or OPC XML). | |
UnsubscribeMultipleEvents | Unsubscribe from changes of multiple OPC events. Unsubscribe from changes of multiple OPC events, specifying array of integer handles. |
