WinCC V13 Professional RT on IPC677C doesn't communicate with S7-300

Hello,

We've created a project on a standard PC (WinCC Prof. V13 SP1 RC), then downloaded to IPC677C  (WinCC RT Prof. V13 SP1). The application doesn't communicate with S7-300. Ping from IPC to S7-300 is OK.

The Run simulation on the standard PC communicates with S7-300.

We suppose that there must be some setting in Connection->Access point but we don't know exactly what to do.

Can anyone help us?

Hello,

open Set PG/PC INterface in the Windows Control panel on the IPC.
Set for the access point S7ONLINE the Networkcard with which the ipc is connected to the PLC.

Regards
Christoph

Also make sure Simatic Net itself has been installed.

I often encounter people overlook/forget this point.

And about setting the PG / PC Interface, see the following link explaining it for WinCC 7.x.

It is basically the same for WinCC Professional:

How do you set the PG/PC interface with a TCP/IP connection in the S7 Protocol Suite?

for winCC V13 you do not need a Simatic Net INstallation!

This only need if you use WinCC V7.x!
