Feeder Protection Relay
Technical Reference Manual
The default class settings of the DNP points within the different event object groups
are:
• binary inputs change events: class 1
• analogue inputs change events: class 2
• counter change events: class 3
All static data points belong to class 0.
Unsolicited reporting is enabled for all event objects as default. However, the
point-specific enable/disable parameters are meaningless unless unsolicited
reporting has been enabled with SPA parameter 503V24.
The pointers to the scaling factors for analogue objects are all 0 as default.
Consequently, the DNP and Modbus analogue values of REF 610 are identical as
default.
All DNP process points can be edited using the Relay Setting Tool. Editing features
include:
• re-organizing, adding and removing DNP points
• assigning event classes to specific DNP points
• DNP point-specific enabling/disabling of unsolicited reporting
• defining deadbands for event reporting
• defining scaling factors for analogue values
