Output:
The Output Assembly is the collection of command & configuration data that is sent as an
output from the PLC and consumed by the interface card. Its structure is defined by the
Consumed Register Configuration as described in section 5.8.4. The Output Assembly Instance
must be set to 100 when connecting to the vendor-specific I/O assembly instances (or 20/21 when
using the ODVA AC/DC drive profile), and the size must be set to the number of 16-bit registers
that we wish to send to the interface card. For the purposes of this example, we are assuming that
the consumed configuration array is defined as shown in Figure 43, with two relevant registers
(1799 and 1798). We therefore set the Output Size to 2.
Configuration:
The Configuration Assembly Instance is unused, and its instance number and
size are therefore irrelevant (you can just enter “1” and “0”, respectively).
When done, click “OK”.

You should now see the new module (named “ETHERNET-MODULE Fuji_Inverter”) in the 1756-
ENBT/A branch under the I/O Configuration in the controller organizer view. Right click on this
new module, choose “Properties”, and select the Connection tab. Refer to Figure 88.
Confirm the setting of the Requested Packet Interval (RPI). The RPI defines the amount of time
(in milliseconds) between data exchanges across an I/O connection. The smallest RPI supported
by the interface card is 10ms.
When done, click “OK”.

After adding the I/O Module to the configuration, the full I/O
Configuration tree should appear similar to Figure 89.

Switch to online mode and download the project to the
PLC. Verify that the newly-added inverter is available and
operating correctly by observing any indications shown on
the inverter’s icon. When the inverter’s icon is selected, its
status and any available error messages will be displayed
in the area below the project tree. Refer to Figure 90.
Also confirm that the interface card’s “Network Status”
LED should be solid green, indicating an
“online/connected” state.
8)
By double-clicking “Controller Tags” in the project tree,
it is possible to view the newly-added tags. Refer to
Figure 91. The Fuji_Inverter:C configuration tag is
unused, the Fuji_Inverter:I tag allows viewing of the
input data, and the Fuji_Inverter:O tag allows
modification of the output data. These tags will be
synchronized with the inverter at whatever rate was
established for the module’s RPI.
