1. Add the DNP Serial Slave OPC Client object in the Communication structure by
selecting the Gateway object.
2. Right-click the Gateway object and select New > DNP > DNP Serial Slave OPC

Adding Channel objects
After the DNP Serial Slave OPC Client object has been successfully added, you can
continue building the object tree by adding a DNP Serial Channel object.
To add DNP Serial Channel object:
1. Select a DNP Serial Slave OPC Client object and right-click it.
2. Add a DNP Serial Channel object.
3. Rename the new object. The names of the DNP Serial Channel objects within a
DNP Serial Slave OPC Client have to be unique.
Adding DNP Serial IED object
After a channel object has been successfully added, you can continue building the
structure by adding the a DNP Serial IED object. All the data can be connected to one
device or divided to several slave devices. Before dividing data to several slave devices,
it must be checked that the current protocol mode and the master system support the
feature.
To add DNP Serial IED object:
1. Select a DNP Serial Channel object.
2. Add a DNP Serial IED object.
3. Rename the new object. The names within a DNP Serial Channel have to be unique.
Adding data objects using Cross-References function
Data objects are added somewhat differently than the upper level objects. Basically, you
drag and drop the data objects you need from an OPC server to the DNP Serial Slave
OPC Client.
To add data objects:
1. Select DNP Serial IED object and right-click it.
2. Select Cross-References. The Cross References function appears (Figure 3.3.5-1).
3. In the Project Explorer, select now a logical node within an OPC server, from which
you want to connect the data objects to DNP Serial Slave OPC Client.
Note that you can also select an upper level (server, channel, etc.) object and drag
and drop it into the Cross-References function. As a result, all the data objects within
the selected object appear now in the Cross-References function and can be connected
to DNP Serial Slave OPC Client.
