Features and System Configuration
Features
■
This Unit provides a communications interface between
OMRON PLCs (e.g., the CS, CJ, and NJ Series) or other
CompoNet-compatible masters manufactured by other
companies and Sensor Amplifier Units.
●
Remote I/O Communications Slave
ON/OFF outputs from Sensor Amplifier Units can be sent to the host (master) PLCs
with remote I/O communications without any programming.
●
Message Communications
You can send commands (explicit messages) from the PLC to read and write
parameters, such as detection levels and thresholds, and perform operations, such
as tuning.
●
Dummy Sensor Registration
You can register Dummy Sensors so that you do not need to change the I/O
assignments even if the number of Sensor Amplifier Units changes. You can also
choose to return either an error or a normal completion when a command is sent to a
Dummy Sensor. Explicit messages are used to register Dummy Sensors.
