Remote I/O Functions
5-6 Control Remote I/O Operation
The control I/O remote I/O function is a proprietary OMRON format, not a remote I/O format specified
by DeviceNet.
This remote I/O function’s features and arrangement match the control terminal I/O signals of the
3G3MV/3G3RV/3G3PV/3G3FV Inverters, so it can be used for communications with the Inverter’s
multi-function inputs. There are also default settings available 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).
