Slave cannot enter OP state

Hello, everyone. I configured a slave station, which is not a servo, but an EtherCat IO device. After I configured it, it cannot enter the OP state. After starting Linuxcnc, it first enters the SAFEOP state and then reports an error. I tried many methods but failed. I hope someone can help me find out what is wrong. I can read the slave information, but I cannot change the IO status of the slave. Thank you very much for this.The following is the XML file I configured and the XML file of my IO device.   

please post the output from "ethercat pdos -p3" and "ethercat pdos -p3 -v" ;

set ec debug level to 1 "ethercat debug 1" and post the output from dmesg after starting linuxcnc

Hello, I have kept you waiting for a long time. Here is my output. Please check if there are any errors that need to be corrected

test this xml.

look at the differences in the edited file and the picture from your last post.
There have been some errors in your pdo config.

I have tried. Your XML file has no problem. You can run my slave and enter OP mode. Thank you very much for answering my question. Thank you again for helping me with my week's work. Another question, do you have a tutorial on the configuration of XML files and hal files? I want to learn something.
