Because both the EtherNet/IP consumed and produced data word configurations are comprised of 32
register definitions, the targeted “offset/element” must be within the range of 0 to 31 inclusive. Refer to
Table 36 for some examples of N50 accesses.

The application PLC program uses a MSG instruction that is configured with a “Data Table Address”
from which to start the access and a “Size in Elements” which determines the number of items to access
(read or write). The “Data Table Address” is constructed by selecting a “File/Section Number” and an
“Offset/Element” according to Equation 3. For example, a “File/Section Number” of N11 and
“Offset/Element” of 0 = N11:0, which corresponds to register 100 (the inverter’s status register).
