5-1-2 Types of Remote I/O Operation
There are three types of CompoBus/D Communications Card remote I/O operation:
• Basic remote I/O: Remote I/O operation for the standard DeviceNet configuration.
• Standard remote I/O: Remote I/O operation (DeviceNet-compatible) that is the default setting for the
CompoBus/D Communications Card.
• Special remote I/O: Remote I/O operations that enable using all the functions of 3G3FV-series Invert-
ers, and accessing/setting for all parameters. (Special remote I/O operation is special for this product;
they are not compatible with DeviceNet.)
The default setting is for standard remote I/O operation, so it will be necessary to switch to either of the
other types of remote I/O operation if desired. Switching the remote I/O operation involves the use of
message communications. Refer to 5-2 Message Communications and 5-3 Switching Remote I/O Op-
eration.
H Basic Remote I/O
Basic remote I/O is used for the standard DeviceNet configuration.

Note 1. A shaded box indicate that the bit is not used.
Note 2. The basic remote I/O operation is the same as those explained for standard remote I/O. (Ba-
sic remote I/O restricts the operation of standard remote I/O.)
H Standard Remote I/O
Standard remote I/O is the default setting for the CompoBus/D Communications Card.
