The BMXNOR0200H module generates events on changes of state, handles events lists and provides the following services:
-
The management of a buffer of events (time stamped or not), overall buffer (queue) size can be up to 100,000 events (the maximum value is 100,000 from RTU 1.5).
NOTE: One dedicated event buffer is managed per client/master application (up to 4 client/master applications are supported).
-
Automatic event backfill to the SCADA or the master station via RTU protocol facility (on DNP3 and IEC 101/104).
For RTU slave configuration (DNP3 slave, IEC 60870-5-101 slave and IEC 60870-5-104 server), each object type has an independent event queue setting. To generate an event, set an event queue for the corresponding object type.
A dialog box is used to configure the event generation:
Object Group
Point Count
The user can map event queue status to CPU registers. The status for each event queue is a 32-bit register (2 words in CPU). A higher word 1 means the event queue has overflowed. The lower word is the number of events in the event queue.
From the Web site, select event mapping:
NOTE: When the events number exceeds the configured buffer size, events will be lost or overwritten.
Increasing Maximal Event Buffer Size
You can increase the maximum events buffer size from 10,000 to 100,000 (in case of one client connection).
NOTE: All channels can support up to 100,000 events, but each point type only supports up to 65,535 events.
A dialog box is used to configure the maximum event count:
