Filter Time of DNP
captures
This is a shutter type of filter for DNP3 point change detection that is
implemented in the code, per DNP3 specifications. Refer to Section 6.3.4.DNP3
Polled Object Parameters –Push-Back Messages (Section b) It is a WORD
denominated in milliseconds. Value: 10 to 32000; default is 250ms. The filter
value is set in the COMMREQ instruction when the station is parameterized.
Duplicate LLA
Addresses
Each master station communicating with the Outstation must have a unique LLA
address. The DNP3 code manages the connections using the LLA address and as
such the Outstation cannot handle duplicate LLA Source (Master Station)
addresses.
DNP3 Code will
not start with NO
Network
connected
The EDS001 module will not start the DNP3 Outstation portion of the application
if NO network is connected to the EDS001 module. This can be worked around
by using a Loopback style of RJ-45 Ethernet connector to indicate a network
presence to the EDS001 module.

Systems.
ST
Structured Text: a programing language supported by RX3i CPUs.
ST Block
A program block within ST. In this application one uses a single ST Block to
convey a COMMREQ from the RX3i CPU to the EDS001 in order to set up all
its DNP3 parameters.
SOE
Sequence of Events: a generic term used to describe a mechanism that can
detect data change, then time-stamping each change for the purpose of
establishing the sequence in which the changes were detected.
TCP/IP
The Transmission Control Protocol (TCP) is one of the core protocols of the
Internet Protocol suite (IP), and is so common that the entire suite is often
called TCP/IP. TCP provides reliable, ordered and error-checked delivery of a
stream of octets between programs running on computers connected to a
local area network, intranet or the public Internet. It resides at the transport
layer.
Variance
A specification sub-group of Group that typically refers to a format of the
data, or a specific sub-command to an action, as defined in the DNP3
Specification. Variance many times is a micro sub-category of Object and is
not unique when describing Objects and Groups.
