The number of events that can be defined in the system is limited to 400. The
event buffer will overflow in systems which are very dynamic unless one of the
following conditions exist:
ƒ The master frequently polls the slave device for events to keep the buffer
empty.
OR
ƒ The slave is configured to send unsolicited messages to the master station.
This method requires full-duplex operation of the network because the slave
may be sending a message during a request from the master station.
In order to disable the report by exception feature in the module, set the number
of events to 0 for the BI Class, AI Class, and Float Class parameters within the
DNP.CFG files. This will cause the slave to never generate event data for
classes 1, 2, or 3.
