A means by which the DNP3 Master Station can set an analog value at the
Outstation. The EDS001 Outstation supports signed 16-bit and 32-bit data,
as well as 32-bit PLC Real variables.
Advanced User Parameters for Ethernet configuration, a file which contains
specific parameter overrides and options for the Ethernet Module.
A request from a master station to an Outstation for all the data for all points,
Data Object Group 60, Variance 1.
A request from a master station to an Outstation for the event data which is
stored in the Outstation, typically with time and status information. This data
can be further organized by groups, representing the class number.
Specifying the Class Number ensures that only those points that are part of
the group are returned. The EDS001 groups digital data into class 1 and
analog data into class 2.
A Communications Request Instruction supported by RX3i CPUs. Conveys
data from the RX3i CPU to a designated target device. In this application, a
single COMMREQ conveys all the DNP3 Outstation parameters to the
EDS001.
A Control Relay Output Block (Data Object Group 12, Variance 1) is the
method used to set a bit in the PLC from a Master Station. It represents a
physical action of select before operating for an Outstation to set a bit over
DNP3.
Distributed Network Protocol
Specific implementation of DNP
Indicators that are returned to the Master Station from the Outstation, in
general to describe point-related conditions which may exist at the
Outstation.
A specification sub-group of Object that refers specifically to a data type,
point action, or Outstation action as defined in the DNP3 Specification.
Group is a macro sub-category of Object and is unique when describing DNP3
Objects.
