9.1
Signal configuration user information
GUID-AC54A350-D43E-4C0C-995C-012D7533ECC1 v4
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.
9.2
Adding setting groups
GUID-9C636C53-898E-4A60-9DDA-1DB13A65EE30 v1
In order to show for a DNP master which setting group is used, the following procedure can be
performed.
In this example, only setting groups one and two are used. The DNP master will get two binary
inputs: the first is set if setting group one is used, the second is set if setting group two is
used.

Configure ACTVGRP (Basic IED functions) and SP16GGIO (Monitoring) with the Application
Configuration Tool (ACT).
