Hi Sir : I really appreciate your reply! I follow your suggestion to use diagnostic tab and save it as attached file. I think there is something wrong with my OB1. I have a PC software and it can read I&M data of my IO device. And I also use Wireshark to record the frame of Ethernet package as attached file. The Wireshark logs shows the index of I&M0 is AFF0 and in Api: 0x0, slot: 0x0/0x1. I also found a datasheet in Chinese and it describes the structure of AR-->Api-->Slot-->subslot to determine the ID. However, I still do not understand what ID I should use in my program. Could you give me suggestion? Best regards, Marcus AttachmentSFB52.zip (137 Downloads) |
