Siemens WINCC(TIA) Communcation with STEP7 V5.5

Dear Experts:

I have a new project of using 2 Siemens CPU-318 using DP communcation with TIA HMI,

Is there something need to set in communcation setting?

I just set 2 name of Connections in Device setting of communcation driver SIMATIC S7 300/400.

They are all in one network and use different DP address.

Nothing difference else.

Please give me some suggestions.

Thanks and with best regards
