2-2 Connectable Sensor Amplifiers
This section explains the types of connectable sensor amplifiers with EtherCAT Sensor Communication
Units.
* The E9NC-TA0 is supported from E3NW-ECT Ver 1.03. The E3NX-CA0 is supported from E3NW-ECT Ver 1.06.
The E3NX-MA0, E2NC-EA□0, E9NC-AA□0/VA□0/VD□0 are supported from E3NW-ECT Ver 1.08 of the
E3NW-ECT. You can check the version with object index 100A hex. (Refer to "A-1-4 Communication Objects" on
page A-4.)
This Sensor Communication Unit allows you to connect up to 30 Sensor Amplifiers, including those that
are connected to the Distributed Sensor Units.
You can connect up to 10 Sensors to a Distributed Sensor Unit.
You can connect up to eight Distribution Sensor Units in one Sensor Communication Unit.
* Also refer to the Sensor Amplifier specifications, as the number of connected units varies depending on the
Sensor Amplifier specifications.
