2-1 E3NW-CCL Overview
This section provides an overview of the E3NW-CCL Sensor Communications Unit.
The Sensor Communications Unit is used to monitor Sensor Amplifier Unit ON/OFF outputs and
detection levels, write parameters, and perform operations between Digital Sensors and a PLC with a
CC-Link communications interface.
The E3NW-CCL has two operating modes. The operating mode is selected via the baud rate/operating
mode setting switch.
Reduced I/O Mode: This mode allows for many devices to be connected by limiting the number of
allocated stations and allocated points.
Monitor Mode: This mode allows for realtime monitoring and control to utilize Amplifier Unit
settings and the monitoring.
*1 This is the total number of Sensor Amplifier Units that can be connected to the Communications Unit and
Distributed Sensor Units.
Symbols: OK: Supported, NA: Not supported.
