How is the connection between a Windows-based panel and a SIMATIC S5 set up?

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 the TP177 and xP277 operator panels for connecting to a SIMATIC S5 controller.

There are two possible options:

Option 1: for a maximum distance of 3.2 meters
