for each channel. Once DNP is assigned to a serial port, the Modbus protocol is disabled on that port. When this setting is
set to "Network - TCP", the DNP protocol can be used over TCP/IP on channels 1 or 2. When this value is set to "Network -
UDP", the DNP protocol can be used over UDP/IP on channel 1 only. Refer to Appendix E for additional information on the
DNP protocol.
Changes to the DNP CHANNEL 1 PORT and DNP CHANNEL 2 PORT settings take effect only after power has
been cycled to the relay.
NOTE
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.
The setting is the DNP slave address. This number identifies the L60 on a DNP communications link. Each
DNP ADDRESS
DNP slave should be assigned a unique address.

ited responses are sent is determined by the L60 from the current TCP connection or the most recent UDP message.
The DNP scale factor settings are numbers used to scale analog input point values. These settings group the L60 analog
input data into the following types: current, voltage, power, energy, power factor, and other. Each setting represents the
scale factor for all analog input points of that type. For example, if the
all DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000
V on the L60 will be returned as 72). These settings are useful when analog input values must be adjusted to fit within cer-
tain ranges in DNP masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (that is, the value will be 10
times larger).
