It depends on the setting parameters of your CIE-H10. To get the current value of [Input Port Base Address] of your CIE-H10, you can: Connect ezManager to your CIE-H10 ==> I/O port ==> Basic Settings. Then you can find the value of [Input Port Base Address] in Modbus/TCP section. For your reference, by default, the value of [Input Port Base Address] is set to 0, so that the value of Starting address(2 bytes) is 00 00. And in that case, the request data will look like: 03 00 00 00 01 Could you please check your setting parameters and verify again? Thank you very much.
