
12.1 DeviceNet Function
This controller enables adding of a DeviceNet function by a DeviceNet module. This chapter
describes the DeviceNet interface.
DeviceNet is a field network interface that features a minimized wiring design in a low-cost
structure and high-speed data communication. The DeviceNet interface allows data
communication for various input/output and jog operation.

12.1.1 Overview
This controller can be handled as a DeviceNet slave station for enabling I/O data communication.
For details of the DeviceNet system specifications and various limitations, refer to the document
published by ODVA (Open DeviceNet Vendor Association, Inc.) or the document supplied with the
master station unit of the DeviceNet system.
