5.2 PRODUCT SETUP
USER MAP FOR DNP ANALOGS
smaller Modbus User Map. This can be useful for users wishing to read only selected Analog Input points from the L90.
See Appendix E for more information
NUMBER OF SOURCES IN ANALOG LIST
are included in the Analog Inputs points list. This allows the list to be customized to contain data for only the sources that
are configured. This setting is relevant only when the User Map is not used.
DNP SCALE FACTOR
log Input data into types: current, voltage, power, energy, and other. Each setting represents the scale factor for all Analog
Input points of that type. For example, if the
Input points that are voltages will be returned with values 1000 times smaller (e.g. a value of 72000 V on the L90 will be
returned as 72). These settings are useful when Analog Input values must be adjusted to fit within certain ranges in DNP
masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (i.e. the value will be 10 times larger).
DNP DEFAULT DEADBAND
containing Analog Input data. These settings group the L90 Analog Input data into types: current, voltage, power, energy,
and other. Each setting represents the default deadband value for all Analog Input points of that type. For example, in order
to trigger unsolicited responses from the L90 when any current values change by 15 A, the
setting should be set to 15. Note that these settings are the default values of the deadbands. DNP object 34 points
can be used to change deadband values, from the default, for each individual DNP Analog Input point. Whenever power is
removed and re-applied to the L90, the default deadbands will be in effect.
DNP TIME SYNC IIN PERIOD
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
DNP MESSAGE FRAGMENT SIZE
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to be
necessary which can provide for more robust data transfer over noisy communication channels.
DNP BINARY INPUTS USER MAP
DNP Binary Inputs list on the L90 contains 928 points representing various binary states (contact inputs and outputs, virtual
inputs and outputs, protection element states, etc.). If not all of these points are required in the DNP master, a custom
Binary Inputs points list can be created by selecting up to 58 blocks of 16 points. Each block represents 16 Binary Input
points. Block 1 represents Binary Input points 0 to 15, block 2 represents Binary Input points 16 to 31, block 3 represents
Binary Input points 32 to 47, etc. The minimum number of Binary Input points that can be selected is 16 (1 block). If all of

When using either of the User Maps for DNP data points (Analog Inputs and/or Binary Inputs), for UR relays
with the ethernet option installed, check the "DNP Points Lists" L90 web page to ensure the desired points
lists have been created. This web page can be viewed using Internet Explorer or Netscape Navigator by
entering the L90 IP address to access the L90 "Main Menu", then by selecting the "Device Information
Menu", and then selecting the "DNP Points Lists".
