WinCC analog scaling

[loonx 0]

For analog display, i would like to do the scaling on WinCC instead of on PLC. Example: Analog raw value 0-4000 (4-20mA) Scaled to 0-100% for display on WinCC. How to do it??

Hi loonx. One way u can do this is by using C-Script. U can read the value using GetTagWord, then apply the formula of scaling & store the result in some internal tag using SetTagWord. By the by, step7 has standard built in blocks for scaling...Y du u need to do it in wincc!!!!??? Gud luk!!! Regards Nil
