Object 1
For every point included in the device profile document there is a che
of class 0 and radio buttons for class 1, 2 or 3 membership. Any point
be a member of one of the change event classes 1, 2 or 3.
Points that are configured out of class 0 are by default not capable of gene
events. Furthermore, points that are not part of class 0 are effectively removed from
at point number 0. The renumbered point numbers are shown
screen in S1 and can be printed out to form a revised device pr
mechanism allows best use of available bandwidth by only reporting
by the user when a poll for all points i
Object 20
The running counter value of object 20 points can be configured to be in or out of class 0.
Any running counter that is in class 0 can have its frozen value selected to be in or out of the
DNP3.0 response, but a frozen counter cannot be included without the corresponding
running counter. As with object 1, the class 0 response will be renumbered into a contiguous
list of points based on the selection of running counters. T
running are not also se
counters having different point numbers to their running counterparts. For example, object
20 point 3 (running counter) might have its frozen value reported as object 21 point 1.
Object 30
For the analog inputs, object 30, the same selection options for classes 0, 1, 2 and 3 are
available as for object 1. In addition to these options, which behave in exactly the same way
as for object 1, it is possible to change the deadband setting for each point. The minimum
and maximum values and the resolution of the deadband settings are defined in the device
profile document; MiCOM S1 will allow the deadband to be set to any value within these
constraints.
SK5 PORT CONNECTION
The lower 9-way D-type connector (SK5) is currently unsupported. Do not connect to this
port.
