Event Management

Introduction

The BMENOR2200H module generates events on changes of state, handles event lists, and provides these services:

The management of a buffer of events (time stamped or not), overall buffer (queue) size can be up to 150,000 events.

NOTE: One dedicated event buffer is managed per slave/server application (up to four slave/server applications are supported).
Automatic event backfill to the SCADA or the master station via RTU protocol facility (on DNP3).

For the RTU DNP3 slave configuration, each object type has an independent event queue setting. To generate an event, set an event queue for the corresponding object type.

Access the Configuration

Access the event configuration in Control Expert:

Step	Action
1	Follow the directions to configure a server channel.
2	Expand (+) Channels → DNP3 NET server → <ServerName>,
3	Select one of these items from the Select Type Id pull-down menu on the DATA MAPPINGS tab: Generate Events Clear Events
4	Select the Add button to view the parameters for the selected type: Generate Events: Point Number Point Count Object Group Point Name Add CMD_STATUS Clear Events: Object Group Point Name Add CMD_STATUS NOTE: When the Control Expert window is active, you can hover the cursor over any field to see a description of the functionality and the available range of values.
5	Click the Apply button to implement your configuration changes. Click the OK button to implement your changes and close the dialog box.

Event Queue Setting Page

Configure the parameters on the Events tab to map the event queue status to the DDDT registers in the CPU. Each event queue status consumes one three-byte register.

NOTE: When the events number exceeds the configured buffer size, events are lost or overwritten.

Access the event queue configuration in Control Expert:

Step	Action
1	Expand (+) Channels → DNP3 NET server → <ServerName>,
2	Make a selection in the Select Type Id pull-down menu on the EVENTS tab
3	Select the Add button to view the parameters for the selected type: Event Store Mode Max Event Count Buffer Setting Max Event Count-1 Max Event Count-2 Max Event Count-3 Event Backup NOTE: When the Control Expert window is active, you can hover the cursor over any field to see a description of the functionality and the available range of values.

Maximum Event Buffer Size

You can increase the maximum event buffer size from 10,000 to 150,000 (in the case of a single client connection).

NOTE: All channels can support up to 150,000 events, but each point type only supports up to 65,535 events.
