The HMI device image is a file that can be transferred from the configuration PC to the HMI
device. The HMI device image contains the operating system of the HMI device , including
the elements of the Runtime software required for the executable project file.
I/O field
Enables the input or output of values on the HMI device and their transfer to the PLC.
Info text
