Connecting PROFINET
Note
Use a cross-cable for the PROFINET connection when using a point-to-point connection.
Note
PROFINET IO
If you use PROFINET IO direct keys, the HMI device must be connected with a switch. For
detailed instructions regarding the installation of PROFINET networks, please refer to the
PROFINET system description manual.
Only connect the HMI device to public Ethernet networks using a switch or comparable
device.
Configuring an RS 422/RS 485 interface
A DIP switch for the configuration of the RS 422/RS 485 interface is located on the back of
the HMI device.
In the factory state, the DIP switch is set for communication with the SIMATIC S7 PLC via
RS 485.
Note
