5 Setting Up EtherCAT Communications with the Sysmac Studio
5-1 Overview of Network Configuration
Information
To execute EtherCAT communications, you must create the following three types of data with the Sys-
mac Studio and download the data to the CPU Unit. When this data is set, the network configuration
information is automatically created.
When you download the network configuration information to the CPU Unit, the EtherCAT master initial-
izes slaves and performs process data communications based on the network configuration informa-
tion. This section describes the procedures to set the network configuration information and how to
check EtherCAT communications.
