Instructions:
SIMATIC HMI Windows-based panels do not possess a TTY (20mA) interface which is needed for communication with a SIMATIC S5 PLC.
Exception:
The MP 370 operator panel possesses a TTY interface. Furthermore, the interface can be switched between V24 and TTY on a panel PC in the BIOS.
For all other Windows-based panels you need an adapter (9-pin female to 25-pin male) and an RS232/TTY converter cable for connecting to a SIMATIC S5.
Note:
The AS511 driver is no longer available for some operator panels for connecting to a SIMATIC S5 controller.
The latest information about which devices support the AS511 driver is available in the Online Help of WinCC flexible and ProTool, in the relevant manual of each operator panel, in the communication manual and in the ST80 catalog.
Below is an excerpt from the WinCC flexible Online Help.
