5-4 Special Remote I/O Operation

There are three kinds of CompoBus/D remote I/O operation: Basic remote I/O, standard remote I/O (the default setting), and special remote I/O. This section explains special remote I/O.

Special remote I/O operation enables using all the functions of 3G3FV-series Inverters, and setting and reading all parameters. These operations have been developed independently, and are not part of the DeviceNet standard.

5-4-1 Overview of Special Remote I/O

Special remote I/O operations utilize CompoBus/D (DeviceNet) remote I/O, and can directly write to and read from internal Inverter registers. Basically, the register numbers for the various functions shown on this and subsequent pages are specified for writing or reading. Once data has been written, it is re- tained until it is changed by the next write operation.
