5-10 Confirming Communications after
Completing EtherCAT Configuration
and Settings
If normal network configuration information is downloaded to the CPU Unit, EtherCAT communications
start automatically regardless of the operating mode of the CPU Unit.
After the start of EtherCAT communications, check the process data communications status to ensure
that process data communications are performed normally between the EtherCAT master and all
EtherCAT slaves.
Checking the Process Data Communications Status
Use one of the following methods to check the process data communications status.
• Controller status monitor of the Sysmac Studio
• System-defined variable
• Indicator
The contents of checking the process data communications status using these methods are given be-
low.

Controller Status Monitor of the Sysmac Studio
On the detailed view of the Controller status monitor, check the item for EtherCAT Process Data
Communications . If the item for EtherCAT Process Data Communications is Communicating ,
process data communications are performed normally. Refer to the Sysmac Studio Version 1
Operation Manual (Cat. No. W504) for how to display the Controller status monitor of the Sysmac
Studio.

System-defined Variable
Check the _EC_PDActive (Process Data Communications Status) system-defined variable in the
user program. If _EC_PDActive is TRUE, process data communications are performed normally.

Indicator
EtherCAT communications are in Operational state (process data communications are performed
normally) if the EtherCAT NET RUN indicator on the front of the NJ/NX-series CPU Unit is lit green.
Checking and Correction Methods if Process Data Communica-
tions are not Performed Normally
If process data communications are not performed normally, check the event log in the Sysmac Studio
and take suitable measures. Refer to
Error Tables in Errors in the EtherCAT Master Function Module
in the NJ/NX-series Troubleshooting Manual (Cat. No. W503) for event logs.
