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 controller (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 controller. Time stamping resolution depends on the controller scan time and I/O module type.

Event Buffer Capacity in RAM

The number of events in the buffer observes these limitations:

  • The module records up to 150,000 event in the event buffer.

  • The event buffer is synchronized (if event sync is enabled) between the primary and standby modules in a redundant system.

  • The module records up to 10,000 security events per server channel in the event buffer.

Retain or Clear the RAM

The event buffer in RAM is retained in these situations:

  • The controller experiences a warm start.

  • There is a network swap in a dual-network application.

The event buffer in RAM is cleared in these situations:

  • Use a Clear Events command to clear the buffer in RAM.

  • The controller experiences a cold restart (such as during the download of a new configuration) or you press the reset button on the power supply. All communications are reset.

  • Change the DNP3 cyber security configuration on the web page to clear the buffer.

  • A SCADA command specifically clears the buffer.

  • Reset RTU protocol by Device DDT.

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).
