Hi guys, I have the same problem.. I'm try use S7-1200 G2 with IHM KTP900, there is no communication error but they did not exchange any data.. CPU 6ES7214-1AG40-0XB0 and IHM 6AV21232JB030AX0.

Any ideas ?

Split from No data exchange between KTP900 and S7-1200.

Hello,

Please have a look at the following link:

No connection to PLC after WinCC Panel Images V17 Update 6

(Check the Date and Time, it should be actual!!!)

And look at: Configuration of an HMI connection to S7-1500/S7-1200 CPUs

Best regards,
