TMS320F28P650DK: Cannot scan device in the twincat

Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: LAUNCHXL-F28P65X, C2000WARE

F28P65 with EtherCAT 


I use LAUNCHXL-F28P65X Development Kit , Open CCS and import the example f28p65x_cpu1_pdi_hal_test_app,

Then refer to document EtherCAT SubordinateDevice Controller Software User's  Guide to operate .But no matter what I do, I can't scan the Ethercat device normally.

I also tried several times according to Troubleshooting,  including restart twincat or Power-cycle the controlCARD,  but the device was not scanned.

But when I scan my own drive device, I can successfully scan it.


What could be the reason for this?
