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.

HBasic 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.)

HStandard Remote I/O

Standard remote I/O is the default setting for the CompoBus/D Communications Card.
