Section 9 DNP3 communication engineering
9.1 Signal configuration user information
Basic knowledge about DNP3 and the used definitions are required to
use CMT. See the DNP3 communication protocol manual for
information on the DNP3 implementation in the IED.
CMT is a part of PCM600 and allows to configure the signals that are used to
communicate with clients or master units for DNP3 protocols.
On the left window CMT organizes all available signals from the application
configuration in containers that are preselected as signal types.
On the right window CMT provides containers that are selected by tabs. Each
container represents one communication channel. The number of possible
communication channels is IED type dependent. The IED uses TCP/IP as
communication channel. DNP3 can be tunneled over TCP/IP. Serial communication
over RS485 or optical is supported. .
Use direction icons that are located between the windows to move all signals or a set
of individual signals between the windows.
DNP3 signal types, index and default setting for classes are predefined in CMT. Adapt
the signal configuration to project definitions. The signal type can not be modified due
to the fact that the internal signal set up is fixed.
When the default configuration values are sufficient, the task is finished when all
signal are moved according to the project requirements.
With the Save option, the signals are stored for the communication part of the IED
according to the default selections.
Only for analog measurements additional configuration parameters are shown to do
signal scaling to DNP3 protocol presentation. This can be done when the
Configuration Table View is selected.
Finally, the signal configuration to the different DNP3 channels can be listed in a
report on demand and per signal type.
