New  SIMATIC HMI KTP700F Mobile, article number 6AV2125-2GB23-0AX0 Panel 2nd generation  is not compatible with the old one.

The emergency stop button has only 2 contacts hard wired  and i need the 3 contacts to locate  the emergency stop for the alarm tekst.

Only with a falesafe plc these contacts are visible in the plc and we do not use a fale-safe plc.

Please Tell us about the way you did to install the HMI.

What are  the softwares of Siemens you had installed in your PC?
