CHAPTER 5: SETTINGS
SETTINGS  PRODUCT SETUP  COMMUNICATIONS  DNP / IEC104 POINT LISTS  BINARY INPUT / MSP POINTS
 BINARY INPUT / MSP
 POINTS
Up to 256 binary input points can be configured for the DNP or IEC 60870-5-104 protocols. The points are configured by
assigning an appropriate FlexLogic operand. See the Introduction to FlexLogic section in this chapter for the range of
assignable operands.
Changes to the DNP / IEC 60870-5-104 point lists take effect when the L90 is restarted.
The menu for the analog input points (DNP) or MME points (IEC 60870-5-104) follows.

POINTS
 ANALOG INPUT / MME
 POINTS
Up to 256 analog input points can be configured for the DNP or IEC 60870-5-104 protocols. The analog point list is
configured by assigning an appropriate FlexAnalog parameter to each point. See the FlexAnalog Parameters section in
Appendix A for the range of assignable parameters.
Changes to the DNP / IEC 60870-5-104 point lists take effect when the L90 is restarted.
The DNP / IEC 60870-5-104 point lists always begin with point 0 and end at the first "Off" value. Since DNP / IEC
60870-5-104 point lists must be in one continuous block, any points assigned after the first "Off" point are ignored.
5.3.5.12 IEC 61850 protocol
The L90 is provided with optional IEC 61850 communications. This feature is specified as a software option at
the time of ordering. See the Order Codes section in chapter 2 for details.
The IEC 61850 settings are accessible in EnerVista software or a substation configuration language (SCL) generating tool.
The path is Settings > Product Setup > Communications > IEC 61850 or Settings > IEC 61850. The settings are not
accessible from the front panel of the device.
IEC 61850 messaging can form part of protection schemes. Consider IEC 61850 settings with the same criticality as
protection element settings. To ensure reliable performance of protection schemes utilizing IEC 61850 messaging,
route IEC 61850 traffic on a separate port from SCADA communications, or use redundant, independent ports, and
a high-speed network recovery method, such as PRP.
Overview
IEC 61850 is a series of international standards and technical reports applicable to power utility automation systems. It
includes semantics, abstract communication services, specific communication services, performance specifications,
network engineering guidelines, configuration description methodologies, and engineering processes. The standard
