RZT2M Ecat error

Hello~

When I use the r12an0123xx0300-cn032-ac-servo-solution, I connect to TWINCAT 3.1 on my computer, and I can reach the OP state normally, and I can switch from the OP state to the SO PO IT state.

However, when I try to access the online object dictionary, TWINCAT gives me an error and I can't switch states anymore, it stays in the original state (OP).When I try to locate it, I find that the program is running to Default_Handler.

Is this a CN032 project problem or something else?

Thanks.
