CxEventIF
The CxEventIF control is an automation object that provides a way for scripts to set up and execute filtering queries. The filtering queries can be used for events, activities, and conditions, as well as for point and value information. For example, a script can set up and execute queries to be applied to a shift report.
The main filter and query areas of the CxEventIF object are as follows:
- Alarms in the Common Alarm Service (CAS), filtered by CAS attributes
- Events, including Audit events, in the Event Logging Service (ELS), Alarm Event Logging Service (ELSALM), and the Audit Service (AUD), filtered by event attributes
- History values, for a specific time in the Value History Service (VHS)
- Point information, filtered by Facility Service (FAC) attributes (such as UDC) and Point Service (PNT) attributes (such as facility type and configurable attribute)
- Current values in the Current Value Service (CVS)
There are five query objects available, allowing interfaces with a large number of services. CxEventIF contains the following objects:
- AlarmQuery Object
- EventQuery Object
- HistoryQuery Object
- PointFacQuery Object
- ValueQuery Object
Note: Both 32-bit and 64-bit versions of this library are available; library files are located in your CygNet source files at CygNet\Support\CxEventIF.dll and CygNet\Support64\CxEventIF64.dll respectively.
