The binary inputs points for the DNP protocol, or the MSP points for IEC 60870-5-104
protocol, can be configured to a maximum of 96 points. The data source for each point is
user-programmable and can be configured by assigning FlexLogic operands. For a
complete list, see Format Code FC142.
The menu path for the binary input points (DNP) or MSP points (IEC 60870-5-104) is shown
below.

Up to 32 analog input points can be configured for the DNP or IEC 60870-5-104 protocols.
The menu path for the analog input point (DNP) or MME points (IEC 60870-5-104) is shown
below.

Points
Analog IP Point 0 Entry
Point 0 Scale Factor
Point 0 Deadband
DNP ANALOG INPUT POINT 0(31) SCALE FACTOR
Range: / 0.001, / 0.01, / 0.1, / 1, / 10, / 100, / 1000, / 10000, / 100000
Default: /1
These are numbers used to scale analog input point values. Each setting represents the
scale factor for the analog input point. For example, if the DNP PHASE A VOLTAGE SCALE
FACTOR setting is set to “/ 1000”, and the Phase A voltage is 72000 V, the Phase A voltage
is sent on to the 8 Series relay as 72. The settings are useful when analog input values
must be adjusted to fit within certain ranges in DNP masters.
