What is HMI?

Human machine interface/man machine interface

Hi,

As you don't specify your HMI more detailed: just use a LED and a pushbutton.

Dear HMI which we used with PLC for data input

Hi,

It seems you don't want to give any specification or requirement.
This makes it impossible to give detailed recommendations.

Thanks for reply. What details you want I tried with modbus ASCII but the HMI keeps on sending the strings and after send the return reply to specific string after few milliseconds hmi again send the string

Hi,

HMI is a rather global term. Like "food".
It can be anything from LED to augumented reality, it can be pushbutton, mouse, keyboard, joystick, touchscreen..and many other..
It can be any optical, haptic, accoustic...

"Integrate HMI with microcontroller" means you are setting up a MODBUS server the HMI should talk to? But what's exactly the problem? Do you understand the protocol used by the HMI? How do you configure it? Are you sure your MODBUS implementation is correct? Did you check it with a test tool?
