Hi Mikail. I need to send a command to write updated data to register 6 of slave ID2. The command frame should be “2-byte transaction id, 0x00 0x00 0x00 0x06 0x02 0x06 0x00 0x06 0x01 0x2C”

Thank you, Mikhail. Now I deleted the project and made a new one, which worked. Could the problem be from adding a new device on Device Polling?
