5.2 PRODUCT SETUP
when any current values change by 15 A, the
these settings are the deadband default values. 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.
The
DNP TIME SYNC IIN PERIOD
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The
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.
The
DNP BINARY INPUTS USER MAP
Binary Inputs list contains 928 points representing various binary states (contact inputs and outputs, virtual inputs and out-
puts, 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 repre-
sents 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 the
settings are set to "Not Used", the standard list of 928 points will be in effect. The L90 will form the binary inputs points list
from the

When using the User Maps for DNP data points (analog inputs and/or binary inputs) for relays with ethernet
installed, check the "DNP Points Lists" L90 web page to ensure the desired points lists are created. This
web page can be viewed using a web browser by entering the L90 IP address to access the L90 "Main

# IEC 61850 PROTOCOL
#
The L90 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported
over two protocol stacks: TCP/IP over ethernet and TP4/CLNP (OSI) over ethernet. The L90 operates as an IEC 61850
server. The Remote Inputs/Outputs section in this chapter describe the peer-to-peer GSSE message scheme.

during testing or to prevent the relay from sending GSSE messages during normal operation. Refer to Appendix C: IEC
61850 Communications for additional details on the L90 IEC 61850 support.
Since GSSE messages are multicast ethernet by specification, router networks must not be used for IEC/MMS.
