Q1: Is HMI only used to connect to PLC? That's not true. HMI products are originally produced to solve the problem of PLC human-computer interaction. But with the development of computer technology and digital circuit technology, much industrial control equipment has a serial communication interface ability. So as long as there is a serial communication interface ability of the industrial control equipment, such as VFD (variable frequency drive), DC speed regulator, temperature control instrument, and data acquisition module, they can be connected to HMI products to realize the human-computer interaction function.
