Dear Sir,

My PC install TIA Portal V13 SP 1 Update 6

I try to config SIMOTION D425-2 DP/PN with WinCC RT Professional 

but its not successful as picture below

and connect to WinCC RT Advance is normal

What did I do mistake ?

Hello,

Is the OPC still the only way to communicate with simotion?

Regards.

No.

Comfort Panels work fine with SIMOTION.  Basic Panels (2nd Gen) will also work if the SIMOTION is the only communication partner.

Hello,

In WinCC RT Professional V13 SP1 Update 8 I define a opc xml connection to communicate with a simotion D435 device. When I define tags in design time I can see the variables in D435. I do not get any errors in definition of tags. But I can not communicate with the device when I run my project in Runtime. Is there any setting somewhere I did not do?

Regards, 

I solved the problem. I installed the WinCC Runtime Professional V13 SP1 with different setup file that not combined with editor setup. The difference is Simatic WinCC OPC XML Client component I think.

To communicate with an OPC XML Server be sure Simatic WinCC OPC XML Client component installed to the system.
