PROTOCOL-SPECIFIC INFORMATION
interface card is 1ms. Click OK when done.
21) After adding the I/O Module to the configuration, the full I/O
Configuration tree should appear similar to Figure 43.
22) 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 44. Also confirm that the interface card’s “Network Status” LED
should be solid green, indicating an “online/connected” state.
23) By double-clicking “Controller Tags” in the project tree, it is possible to view the newly-added tags.
Refer to Figure 45. 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 the rate that was established
for the module’s RPI.
We can directly interact with these tags in order to control and
monitor the inverter. In Figure 45, for example, we can see
that the first 16-bit word of output data
(Interface_Card:O.Data[0]) has been set to a hexadecimal
value of 0x0002. The default consumed data word
configuration word offset 0 references register 1, which is the
