The HMI controls of the TX500 product series have high-quality displays with brilliant graphics, resistive touch, and a modern processor. They are ideal for use in small to medium-sized machines, whose processes must be controlled, operated, and observed locally. The CODESYS 3 control of the TX500 has the functions PROFINET controller, EtherNet/IP scanner and Modbus TCP as well as Modbus RTU Master. When used with Modbus protocols, the HMIs can also be operated as slaves. For visualization the CODESYS 3 target is used.
