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

7
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 (contd)
• 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
