Siemens ovn 9700
If your DNP network requires data in a format different than that provided by
the factory DNP configuration, you can edit the setup registers in the DNP
Slave Export modules and the DNP Options module. Do not make any
changes to the DNP Options module’s setup registers unless you
understand the effects each change will cause.
As DNP 3.0 is a very complex protocol, an in-depth understanding of DNP
3.0 is required to interpret the settings in the DNP Options module and the
DNP Slave Export modules. It is beyond the scope of this guide to describe
DNP; consult the DNP User’s Group or other resources to learn more about
the protocol.
DNP Slave Export Module Settings
The 14 factory-configured DNP Slave Export modules are configured as
shown in the following table.
Setup Register Setting
BasePoint Varies – each analog input or binary counter has a different
BasePoint
StaticObj 11 modules are
Analog Input
; three are
Binary Counter
EventObj Disable Event Objects
Deadband 0
FrozStaObj Disable Frozen Static Objects
FrozEvtObj Disable Frozen Event Objects
EventClass Class 1
Scaling OFF (excluding
Unbalx10
and
Freqx10
which are ON)
SEAbusZero 0
SEAbusFull 0 (1000 for
Unbalx10
and 100 for
Freqx10
)
DNPZero 0
DNPFull 0 (10000 for
Unbalx10
and 1000 for
Freqx10
)
As the table indicates, some of the setup register settings vary for different
modules. Specifically, BasePoint will be different for each module within a
group (Analog Input and Binary Counter are groups), and StaticObj is set to
Analog Input for the 11 analog input points and Binary Counter for the three
binary counter points. (StatObj defines the type of DNP object the module
provides when the Master polls it.)
In addition, Scaling is
OFF for all but two modules. The only modules that
apply scaling are the Analog Input points that provide Voltage and Current
Unbalance data (labeled Unbalx10) and Frequency data (Labeled Freqx10).
These modules apply x10 scaling.

DNP 3.0 can only be used
on the X
PRESS CARD’s RS-
485 ports (COM 1 and
Ethernet ports are not
supported).
Only one port per 9700
Power Meter can be used
with DNP 3.0
