OPC AE Client ActiveX fully complies with the OPC Alarms and Events 1.10 specification. It supports all standard AE features, including condition-based, tracking, and simple event notifications.
Yes. Events can be programmatically logged to any data sink, including databases, text file, or third-party historians.
The control includes built-in connection monitoring and automatic reconnection logic. If a connection to an OPC AE server is lost, it can attempt to re-establish communication based on configurable retry logic. Event subscriptions are re-initialized upon successful reconnection.
The ActiveX control itself is 32-bit, as is typical with COM components. It can run on 64-bit Windows systems using 32-bit containers or applications. For use in a 64-bit .NET application, a separate 32-bit host process or wrapper may be required.
Yes. The component architecture allows simultaneous connections to multiple OPC AE servers, whether local or remote. Each connection is independently managed, with isolated event subscriptions and filters.
