Hello everybody
I'm working on a project now. I need to install WinCC SCADA system. The problem is that I also need to have an additional server which will provide access from MES factory level to my archived data and also implement a Web service.
The basic setup is:
2 single user WinCC stations(about 1500 tags max) with Redundancy option in order to provide higher availability of control and prevent loss of data.
What should I install on my dedicated server? I suppose I need a copy of MS SQL Server to accumulate all the data. But how do I put it there? I'm quite confused with available options: Industrial DataBridge, Connectivity station, Central Archive server... What do I really need?! Also, the lowest possible cost is very important. Can I possibly collect all the data using SQL server queries only? After all WinCC stores everything in SQL Server Express instances on the operator stations.
And will any of above mentioned options provide SOAP-compatible XML web-service? Or have I still to code it myself?
So, please can you recommend me any suitable architecture, considering both the cost of software and labour-intensity?
