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".
5)
You should now see the new module (named "ETHERNET-MODULE Interface_Card") 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 44.
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 1ms. Click OK when done.
6)
After adding the I/O Module to the configuration,
the full I/O Configuration tree should appear similar
to Figure 45.
7)
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 46.
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 47. The Interface_Card:C
configuration tag is unused, the Interface_Card:I
tag allows viewing of the input data, and the
Interface_Card: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.
