Dear All, In Normal WinCC project with Step7 using charts, SCADA WinCC act as a OPC Server at control room and Yokogawa server act as a OPC Client DA type. 1. Both are in same network and it can be browsed from both PCs. 2. Username and pasword are also same for both Siemens WinCC OPC Server and Yokogawa OPC Client. 3. All related DCOM settings are also done in windows side in both PCs Here the question is .. From Yokogawa OPC Client, when we are browsing Siemens OPC Server, its started browsing and listed tags but at the end,it says some error as Item Attribute Error and it mentioned as Item ID required space length in server. The communication with Siemens through OPC not established due to the error of the Item Id. Please see the attached snapshot.The OPC server (OPCServer.WinCC) is able to view and browse in DCS but while browsing all the tags are listing and it is failing to acquire item id attribution.(Error Code : 80070057) .See the picture no. 1 & 2. The same server I connected through third party software (Matrikon OPC explorer) from DCS and it is able to connect but giving the error the Item id property is not valid/specified error.see The picture no.3.
