CitectSCADA and DNP
There is currently a new and an old version of the
DNP driver supporting the DNP 3.0 standard
DNPr – New driver with full support for redundancy
DNP – Old
The DNPr driver is a native driver able to
communicate with any device compliant with the
DNP 3.0 standard
From January 1, 2006 a Specialty Driver support
contract is required to log DNPr support calls

DNPr – New features
Time stamped Trends
Trend events (Value & Time) are pushed directly to the
CitectSCADA trend system through API
No need for customer written Cicode – all handled by the
DNPr driver
Record with 1ms accuracy both analog and digital data
for display in either the trending system or process
analyst
Optimizes data storage by only saving values that are
inserted (or changed)
Trend files automatically expand to fit data
No polling load on CitectSCADA

DNPr – New features
Time stamped Alarms
Alarm events (State & Time) pushed directly to the
alarm system through API
No need for customer written Cicode – all handled by the
DNPr driver
Record with 1ms accuracy both analog and digital
Alarms logged from RTU devices
No polling load on CitectSCADA

DNPr – New features
Support of calculated variables
Calculations can be made within the cache before
pushed into CitectSCADA
RealPower = Voltage x Current x PowerFactor (where
Power factor is 0.85)
Timestamp set to latest time from set of variables

DNPr – New features
Redundancy
I/O Server level redundancy provides PLC type
redundancy
No custom redundancy logics, such as dual-master
logic, coding in the RTU required
The driver maintains a database of values received from
devices known as the cache
The cache is updated by both event and static data
The cache is automatically updated between the I/O
Servers upon change of data in the DNP devices

DNPr – New features
Redundancy (cont’d)
Redundancy managed through “Active State Detection”
of units and exclusive port access mode
A unit becomes active if either of the following occurs
Communication between the I/O Devices fails
The unit is forced into the active state by the user
If a unit on an I/O Device is not active
No communication with I/O devices.
It does not send any DNP3 frames to the device and does
not process any frames received from the device
I/O Servers communicate with each other to ensure that
a unit is active on only I/O Server at one time
