Hello Srikant,
Thank you for your reply. I select Device1 (EtherCAT) and goto Actions > Select Set/Reset TwinCAT to Config Mode. Then I'm asked about Active Free Run, I select Yes. This put "SSC Box 1 (TIESC-001)" into OP state when I run demo application. But not when I run full application. It remains INIT state. I can't change state even though I click Op in State Machine. Is my out file of full application incorrect?
Regards,
Kazu
