Hardware requirements
Communication via a point-to-point interface is only possible with a SIMATIC S7-200 1).
You need a PC/PPI cable or a CP e.g. CP 5611 to connect Panel PCs or standard PCs to the SIMATIC S7-200 PLC.
WinCC flexible automatically installs the necessary drivers.
Cables
Note
If you use the new PC/PPI cable 6ES7 901-3CB30-0XA0 with WinCC flexible Runtime, switch to the compatibility mode. It does not support the functionality for 187.5 kbps in this mode.
The new PC/PPI USB cable 6ES7 901-3DB30-0XA0 is supported at present.
Software requirement
The following software components are necessary for communication via the point-to-point interface:
WinCC flexible engineering tool
STEP 7 Micro Win software for the SIMATIC S7-200 PLC
Note
With global data exchange via the "NetR/NetW" function, the interface of the CPU switches to PPI master mode. This may cause interruptions in the connection to the HMI. In certain situations, it may take longer to shut down the connection at the HMI.
Avoid carrying out a slave / master switch with the CPU that is communicating with the HMI device.
