If the operate command is used with the Null relay (00), the module will operate
on the point as single point control. The following table describes the module's
behavior:
Point Index in Command Point in Database Controlled
0 Bit 0 in BO database
10 Bit 10 in BO database
15 Bit 15 in BO database
If the operate command is used with the close relay selected, the module will
operate on the first bit of the two database bits associated with the point. The
following table describes the module's behavior when the close relay is selected:
Point Index in Command Point in Database Controlled
0 Bit 0 in BO database
1 Bit 2 in BO database
10 Bit 20 in BO database
15 Bit 30 in BO database
If the operate command is used with the trip relay selected, the module will
operate on the second bit of the two database bits associated with the point. The
following table describes the module's behavior when the trip relay is selected:
Point Index in Command Point in Database Controlled
0 Bit 1 in BO database
1 Bit 3 in BO database
10 Bit 21 in BO database
15 Bit 31 in BO database
It is important to note that the trip and close relays are linked in the module. If a
latch-on command is sent to the close relay its bit will be set and the associated
trip relay bit will be cleared.
Because the single-point and dual-point control database share the same
memory area, caution should be exercised to prevent control of one area by
another. This can be accomplished by careful design of the system. The dual-
point database could be isolated from the single-point database. For example,
DNP point index 0 to 9 could be used for the dual-point database and correspond
to bits 0 to 19. The single-point control points would then start at DNP point index
20 which corresponds to bit 20 of the database.
Using this technique, the MVI69-DNPSNET module will not require any
configuration for the new dual-point control, and the module will be backward
compatible for current customer applications.
2.4 [DNP Slave Binary Inputs]
This section of the configuration file overrides the Class 2 binary database points.
2.4.1 Point #
This is the information object address of the point.
