After the FieldPoint modules are found, click on the
+
sign next to
FP Res
in the DNH window to expand the device hierarchy and
display the modules found on the network.
The hierarchy should include all of the modules you had connected
to the communications port. Figure 4-1 shows an example of an
expanded device hierarchy. The default name of each device found
includes the model number of the FieldPoint module, followed by the
@ sign, then the address of the module—for example, “FP-1000 @0”.
For each I/O module found, one I/O Item is created for each channel
of the module, and one I/O Item is created to represent all of the
channels on that module collectively.

To configure the hardware settings of a particular I/O module, select
the device in the DNH window.

from
the pop-up menu.

selecting the desired Attribute Value from the list.
f.
If you want to change attributes of a channel from your
application, you can do so by creating data items to represent the
attributes of the channel. To do this, select the attribute from the
Attribute
list and click on the
Create Item
button.
g.
Continue this for each channel that you want to configure.
