Hi,
I have come across the difficulty that you have been facing and completely analyzed the exact cause for the problem with winCC. Having 6 years of sound experience and successful history in dealing with Industrial Automation PLC and SCADA systems (i.e., like designing, programming and configuring PLC and SCADA systems) in different projects, I am confident of accepting any sort of challenges and resolve various kinds of impediments, rationally and precisely, that come with SCADA.
Anticipating your response early. If interested, you can get back to me and feel free to chat with me.
