DNP TCP CONNECTION TIMEOUT
Range: 10 to 300 s in steps of 1 s
Default: 120 s
The setting specifies a time delay for the detection of failed network TCP connections. If
there is no data traffic on a DNP TCP connection for greater than the time specified by
the setting, the connection is aborted by the 845. This frees up the resource for the
connection and allows another DNP TCP connection request.

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.
The menu for the binary input points (DNP) or MSP points (IEC 60870-5-104) is shown
below.

Points
Up to 32 analog input points can be configured for the DNP or IEC 60870-5-104 protocols.
The menu for the analog input point (DNP) or MME points (IEC 60870-5-104) is shown
below.
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 as 72. The 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.
