A-1 Example of Operations for EtherCAT
Slave Unit Communications
This section provides an example of operations for EtherCAT Slave Unit communications with an Ether-
CAT master.
In this example, the NJ-series CPU Unit’s built-in EtherCAT port is used as the EtherCAT master. Refer
to the NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505) for instructions on
using the built-in EtherCAT port on the NJ-series CPU Unit.
The following configuration is used for this example.
