M-6280A Instruction Book
Ordering Selected Points – Selected points can
be reordered to match the users SCADA, RTU or
Master setup by selecting, dragging and dropping
the desired point within the Selected Points window.
Adding Dummy Points – The purpose of the
Dummy Point is to allow the user to match other
device DNP maps that contain points that are not
supported in the control. This feature allows the
user to communicate with the M-6280A control
when it is connected to an RTU that contains other
brands of controls and eliminates the need to
re-configure the RTU or the other controls.
To insert a Dummy point, select "Insert Dummy".
The Dummy Point will be inserted at the end of the
Selected Points list. To move the Dummy Point,
select, drag and drop the point at the desired
location in the Selected Points list. The Dummy point
will assume the Index Position and the remaining
Selected Points will be modified to accommodate
the Dummy Point.
Insert Offset – This allows an offset to be created
in the DNP map without the point number being
transmitted, thus providing the ability to construct a
DNP profile that has non-consecutive point numbers
within a group.
Editing Binary Input Points – The Binary Input
"Value" and "Mask" values can be edited by double
left clicking on the desired point Value or Mask
elements. The default value for Value is TRUE,
which means that the point will return a High or
True when the item being monitored is active in
the control. It can be changed to "FALSE" to match
a SCADA Master if necessary. The "Mask" value
defaults to "CLASS ONE" and defines what polling
class type the point is mapped to. The Mask value
can also be set to CLASS TWO or THREE by double
left clicking on the desired point Mask element.
Editing Analog Input Points – The Analog Input
"Deadband" and "Mask" values can be edited by
double left clicking on the desired point Deadband
or Mask elements. The Deadband can be set to
define when the point will report by exception under
the class type in the Mask setting. When the point
value exceeds the deadband value, it will initiate a
report by exception to the master. The "Mask" value
defaults to "CLASS TWO" and defines what polling
class type the point is mapped to. The Mask value
can also be set to CLASS ONE or THREE by double
left clicking on the desired point Mask element.
Editing Binary/Control Output Points – The
Binary/Control Output Point "Crob", "Mask" and
"Inverse" values can be edited by double left
clicking on the desired point Crob, Mask or Inverse
elements. The Crob (Control Relay Output Block)
setting is used to define what control method will
be used to operate the point. The possible settings
for "Crob" are listed below:
• Latch On • Latch Off • Latch OnOff
• Latch OnOff_TC
• Pulse On
• Pulse Off • Pulse OnOff
• Pulse OnOff_TC
• Paired Close • Paired Trip • Paired TripClose
The "Mask" value defaults to "CLASS THREE" and
defines what polling class type the point is mapped
to. The Mask value can also be set to CLASS ONE
or TWO by double left clicking on the desired point
Mask element.
Inverse defines whether the command to be
sent would be inverted, meaning that when
TRUE is selected, sending a Trip, Close, etc will
have the opposite effect. This was implemented
due to variations seen in RTU manufacturer’s
implementation of direct control with DNP to allow
full compatibility the widest possible number of
RTU’s.
Editing Analog Output Points – The Analog
Output "Mask" value can be edited by double left
clicking on the desired point Mask element. The
"Mask" value defaults to "CLASS THREE" and
defines what polling class type the point is mapped
to. The Mask value can also be set to CLASS ONE
or TWO by double left clicking on the desired point
Mask element.
Editing Counters – The Counters “Mask” value
can be edited by double left clicking on the desired
point Mask element. The “Mask” value defaults to
“CLASS THREE” and defines what polling class
type the point is mapped to. The Mask value can
also be set to CLASS ONE, CLASS TWO, CLASS
NONE, CLASS ONE NOT CLASS 0, CLASS TWO
NOT CLASS 0 or CLASS THREE NOT CLASS 0
by double left clicking on the desired point Mask
element.
