TechTip: Connecting a Control Techniques Drive to a Weintek HMI Using Modbus RTU

This TechTip is about connecting a Control Techniques drive to a Weintek HMI using Modbus RTU. For the purposes of this TechTip, we’re using a CT Comander C300 drive fitted with an AI-485 option module. Drive SetupEither using the drive onboard menu via the keypad, or Control Techniques Connect, software, verify the communications settings (Address, Baud Rate, Data bits, Stop Bits, Parity) as these will need to be matched in your HMI project. Addressing FormatModbus Addressing format for Control Techniques drives is: 40000 + (menu number x 100) + (parameter number) The Weintek HMI does not require the 40000, so Continue reading TechTip: Connecting a Control Techniques Drive to a Weintek HMI Using Modbus RTU
