Remote I/O Functions
!Caution Be sure to set the switches correctly and check the settings before starting opera-
tion. Not doing so may result in malfunction or damage to the product
!Caution Install devices to stop operation as required to ensure safety. Equipment damage
may result. This is particularly important when operation is set to continue for
communications errors because the Inverter will continue operation.
!Caution
Do not carelessly change Inverter's settings. Doing so may result in injury or dam-
age to the product.

Overview of Remote I/O Functions

This section provides an overview of the remote I/O functions, which provide communications
between the Inverter (SYSDRIVE 3G3MV, 3G3RV, or 3G3FV) and the Master.
5-1-1 Overview of Remote I/O Functions
The following table lists the four remote I/O functions that are supported. Use the remote I/O func-
tions most suitable for your application. Also, the Inverter's status can be monitored easily by attach-
ing the status flags (16 bits) to each function and allocating them in the Master. The Unit status flags
can also be allocated independently in the Master.
Note Refer to 5-7 Unit Status for details on the Unit status.

This remote I/O function is compatible to DeviceNet remote I/O function.
The basic remote I/O function is more limited than the standard remote I/O function.
This remote I/O function is the factory setting in the DeviceNet Communications
Unit/Card. General Inverter control can be performed with this remote I/O function.
This remote I/O function is a proprietary OMRON format, not the remote I/O format
specified by DeviceNet.
The special remote I/O function can be used to read/set all of a 3G3MV, 3G3RV, or
3G3FV Inverter's parameters and take advantage of all of the Inverter's functions.
specified by DeviceNet.
The control I/O remote I/O function's features and arrangement match the Inverter's
control terminal I/O signals, so it can be used for communications with the Inverter's
multi-function inputs. There are also default settings in which the Unit status (16 bits)
or multi-function input monitor data (8 bits) is attached to this remote I/O function for
allocation in the Master (data connection path setting)
