Example 2
The legacy protocol default mappings are a selection of the most important signals
produced by the IEC 61850-based protection relay applications. The manufacturer’s
selection of important signals may not always serve every customer.
Any non-protocol-mapped internal signal can be freely connected to a general-
purpose input object via the Application Configuration tool. This object can then be
accessed by the legacy protocol as regular protocol application data.
Example 3
The basic IEC 61850 application model of the protection relay produces a great
amount of information. In some cases, this is more than what is feasible to transport
through a legacy protocol. Via the PCM600/Communication Management tools,
unnecessary data objects can be excluded from the legacy protocol.
However, in some cases a better solution is to OR together several internal signals into
one general signal. This OR output can be connected to a general-purpose input and
accessed by the legacy protocol as regular protocol application data.
General-purpose input object and OR function block may cause
delays to time stamps.
3.5 Standard data object types
3.5.1 Binary inputs
DNP3 object type 1, binary input objects are derived from IEC 61850 data object’s
boolean type attributes, mainly from data classes SPS, SPC, ACD and ACT. Also, few
binary input objects has been converted from enumeral INS and INC classes (ENS and
ENC classes in Edition 2).
The circuit breaker and disconnector double point data objects,
containing open and close bits, also exist in the DNP3 map as normal
single binary input alternatives. These are intended for DNP3
controlling stations that do not support the double bit input DNP3 data
type alternative (Object group 3).
DNP3 object type 2, binary input change events can buffer up to 200 events. When the
buffer becomes full, the new events are discarded until more space is available in the
event buffer.
