Dear friends, hello everyone. Regarding this issue, due to the busy work, it has been a week since then. Currently, we have basically understood the problem. I extracted two different Ethercat master station data from Wireshark and conducted a comparative analysis. From it, we can see that the entries of the PDO have a slight difference in the arrangement order. The main difference is reflected in the two special status words, namely " {0xf200, 0x01, 16}," and {0xf100, 0x01, 16}. We are currently in contact with the manufacturer to confirm these two PDO entries. These two entries are used for a special design. Additionally, there is a problem with the parsing data of the data sent from IGH to PDO by the IO module!
