ICC 
are written via the EtherNet/IP “data table write” service.  Different tags exist for 
reading vs. writing. 
 
Any given register can be accessed with its own unique tag name, or an array 
tag can be used to access a group of registers with one PLC instruction.  Tag 
names are generated according to the following structure: 
 
[action prefix][_reg_][register number] 
 
Where 
[action prefix]
 is a 2-character field, and is equal to either “rd” for read tags, or 
“wr” for write tags.  Although commonly followed for naming clarity, this “read 
vs. write” naming convention is not strictly enforced by the interface card, 
however: it is perfectly acceptable to write to a tag that starts with “rd” and read 
from a tag that starts with “wr”. 
 
[_reg_]
 is just the 5-character sequence “_reg_”. 
 
[register number]
 is a 1- to 4-character field (“1”, “2”…”1484”, “1485”) 
corresponding to the referenced register number. 
 
Examples 
Read “acceleration time 1” (register #10) ................................... rd_reg_10 
Write “option frequency command” (register #1008) .................. wr_reg_1008 
Read “inverter status 1” (register #1402).................................... rd_reg_1402 
 
Additionally, a few special tags exist which provide backward-compatibility with 
V1.000 network interface CPU firmware.  These are specified in Table 4.

To read data from the interface card, the application PLC program must 
reference a “source element” from which to start reading and the “number of 
elements” to read.  The “source element” will be a tag name constructed 
according to the naming convention shown above, or a special tag as shown in 
Table 4.  The “source element” can be either a base tag (such as 
“rd_reg_1301”, which starts at register 1301), or an offset from a base tag (such
