More info at -http://support.automation.siemens.com/WW/view/en/22276718 I sugest you instead of using Simatic Net Server to use DASISIDIRECT Server. The parametization is much easier there. Search for 'DASSIDIRECT' or I can send you manual too... Best regards, Hristo Mihalev

When you connect both stations check in System Managment Console (SMC) in wonderware log file what kind of message is there on the moment of disconnecting. Increasewith 2 OP and S7 basic communications meanwhile too. Best regards, Hristo Mihalev

M.Fouad Posts: 13 Rating: (0)	Thanks Mr/ Hristo Mihalev I will test this new configuration method by increasing the both number of OP communication and S7 basic communication to be 2 for both of them. Then I will tell you about results ! Best regards; Mohamed Fouad
