Hi everyone,
I’m trying to let the operator enter a numeric value (REAL) directly from the PLCnext Web HMI and store it in a PLC variable.
My PLC is the AXC F 2152 and the software version of PLCnext Engineer is 2025.0.1.
However, when I add a „Text Input“ element on the HMI page, I can’t find any option to bind the input to a variable so that the entered value is saved in it.
I’ve tried checking the Action on Data settings (Source Type, Source Variable, etc.), but it’s still not clear how to make the value from the web interface actually write into the PLC variable.
Has anyone faced this? What’s the correct way to bind a REAL variable to a text or numeric input field on the Web HMI? If I can also define some limits it would be awesome.
Thanks in advance!
Hello!
You just need to bind text dynamic to the textInput hmi object.
It will bind variable to be displayed in textInput frame, and enable it’s modifying opportunity by operator.

Unfortunately, there is no limitation mechanism on the hmi side. But you can manage value range of the variable from the plc side, by using fc LIMIT(), or etc.
Thank you!!
