Overview of DeviceNet Communication Type
Overview of DeviceNet Communication Type
Overview
A DeviceNet Communication Type is a communication unit to output ON/OFF data of
multiple fiber sensors, monitor the detection level, write parameters, and operate the unit
via DeviceNet.
The ON/OFF output and monitoring the detection level can be performed using remote I/O
communications without any programming. Moreover, reading and writing any parameters
using Explicit messages, and batch-transfer and monitoring any parameters using a
configurator are possible.
If the Sensor is connected using a connector with a cable, external noise may prevent correct
communication of ON/OFF signals to the Communication Unit. If a high level of reliability is required,
use a cordless connector (E3X-CN02).
When using this product, also refer to the following manuals:
"DeviceNet User’s Manual" (No. W267), "DeviceNet Slave Manual" (No. W404)
