Protocol Parameters Of Reu 610 - ABB REU 610 Technical Reference Manual

REU 610
5.1.16.2.
5.1.16.3.
76
Voltage Relay
Technical Reference Manual - ANSI Version
Data Link is to be used with a transport pseudo-layer. As a minimum, the
transport pseudo-layer implements message assembly and disassembly
services.

Protocol parameters of REU 610

The DNP parameters can all be adjusted using Relay Setting Tool. For the
DNP parameters, refer to Table 5.1.17.-13.
Storing DNP 3.0 parameters
All DNP parameters are stored on the external DNP 3.0 module. After
parameterization with Relay Setting Tool, REU 610 must be switched to the
rear communication mode for at least 10 seconds in order for the DNP
parameters to be replicated and stored onto the DNP module. However, this is
necessary only if the DNP parameters have been altered.
DNP 3.0 point list of REU 610
The DNP data points (binary, analog and counters) of the relay, presented in
Table 5.1.16.3.-1...Table 5.1.16.3.-3, are all in use as default.
The default class settings of the DNP points within the different event object
groups are:
Binary inputs change events: class 1
*
Analog 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 analog objects are all 0 as default.
Consequently, the DNP and Modbus analog values of the relay are identical
as default.
All DNP process points can be edited using 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 analog values
*
