No. 1599	Re: Re: Re: problem to have in status with cieh10	2018-10-17

Dear Jean Claude, As you said, you send FC03 requests to get the DI status of CIE-H10. Refer to page 18 of Modbus/TCP document https://www.eztcp.com/en/download/pds_files/an_modbus_tcp_en.pdf, the request frame for FC03 should include: Function code (1byte) \| Starting address (2 bytes) \| Quantity of Register (2 bytes) So normally, the request data may look like: 03 00 08 00 01 We don't see this function code (0x03) in your request frame, so first please check your request data. You can use Wireshark to monitor your Modbus/TCP data. In case there is still a problem, we can establish a TeamViewer session. You can set up a schedule and send your credentials (ID and password) to us via email support@eztcp.com. Our working time is from 9:00 to 18:00 in UTC+9 Time zone. Thank you for your understanding.
