Target Register File/Section Number Offset/Element Address Format
In addition to providing access to the inverter registers in their “standard” numerical locations as
mentioned above, the registers can also be accessed in a special “assembly object” type format by
targeting integer file N50. What this means is that when N50 is targeted for reading, what is actually
returned by the interface card is the user-defined register data as ordered by the EtherNet/IP produced
data word configuration (refer to section 9.2.4). Similarly, when N50 is targeted for writing, the written
data is disseminated to the inverter’s registers according to the definition contained in the EtherNet/IP
consumed data word configuration. By appropriate configuration of the EtherNet/IP consumed and
produced data word configuration, therefore, bulk access to non-contiguous but frequently-used inverter
registers can be conveniently provided by performing only one read and/or write instruction targeting file
N50.
