WinCC V7.5 SP1 I/O field value updating problem.

Hi Experts,

I am using WinCC V7.5 Sp1 in my project with step7 V5.6 sp2 and controller 412-5h used is this project. 

Communication established between controller and WinCC.

But facing problem in WinCC I/O field, all the I/O field showing zero values whenever I am changing screens in WinCC runtime and when I am setting value in any one of the the I/O field, remaining I/O  field automatically shows the last set value. And these value disappear again after changes the screen. Please suggest the solution for same.

Thanks in Advance! 

Hi,

I/O field configured as Input / Output mode and I am able to change the values also from these I/O field. Zero values showing after changing the picture but in PLC all the values retain only
