Overview

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 server application (up to four server applications are supported).

  • Automatic event backfill to the SCADA or the client station via RTU protocol facility (on DNP3, IEC60870-5-101, or IEC60870-5-104).

For the RTU server configuration (DNP3, IEC60870-5-101, IEC60870-5-104), each object type has an independent event queue setting. To enable event generation, set an event queue for the corresponding object type.

Event Time Stamping

The BMENOR2200H module provides two ways for time stamping of events:

  • Time stamping done at source in the CPU (requires PLC programming).

  • Time stamping done in the BMENOR2200H module (does not require PLC programming).

NOTE: Improved time stamping resolution can be obtained when performing in the CPU. Time stamping resolution depends on the CPU scan time and I/O module type.

Event Generation

Access the event command 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.
NOTE: IEC60870-5-101/104 protocols do not support event generation.

Event Queue Setting Page

Configure the parameters on the Events tab to map the event queue status to the Device DDT 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/Devices > <DNP3 NET Server> > <ServerName>

    – or–

  • IEC10• Server > <ServerName> > <DeviceName>

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.

4

  • Click the Apply button to implement your configuration changes.

  • Click the OK button to implement your changes and close the dialog box.

Maximum Event Buffer Size

You can configure a maximum of 150,000 events for each module, but each point type only supports up to 65,535 events.

Hot Standby Event Performance

When a BMENOR2200H module generates up to 4,000 events per second, the module still supports a Hot Standby switch-over without any event loss (depending on the configuration).

Clearing Events in the Server

Clear_Events supports a new point type which clears the event buffer in DNP3 and IEC60870-5-101/104 servers. It enables the user to clear the events buffer in a local or remote SCADA through mapping memory.

To create Clear_Events for these servers, select Data Mapping.

When the value of the Clear_Events register changes, the BMENOR2200H module clears the events of the object group in the configuration.
