6.13 Enabling PROFINET IO
PROFINET IO
If the HMI device is connected to the PLC via PROFINET, function keys or buttons, for
example, can be configured as PROFINET IO direct keys. If PROFINET IO direct keys are
used in the project, they must be enabled.
Note
If you enable PROFINET IO direct keys, you cannot use the RS 422/RS 485 port
for serial communication.
PROFINET IO direct keys and PROFIBUS DP direct keys are mutually exclusive.
Requirements
You have opened the "PROFINET" dialog with the "PROFINET" icon.
