internal tags

In WinCCflexible, the start value not only is written to the tag during the initial startup of the HMI, but rather at every startup. Tag values are not buffered, i.e. the last value can not be written to the tag on startup.

In WinCC flexible, tags are only initialized during startup of the HMI. An initialization at a later time is only possible indirectly using a user script. The user script evaluates the delta value of the tag which contains the start bit: When the HMI is connected to power, the value of the start bit changes from 0 to 1. The value of the tag that can be initialized with the start value, depending on the delta value of the start bit.

You can configure a start value for numerical tags. The tag will be preset to this value at runtime start. In this manner, you can ensure that the project begins in a defined state.

In the case of external tags, the start value will be displayed on the HMI device until it is overwritten by the PLC or an operator input.

The way to configure your "Start Value":

settings of the tag --> Properties --> Base Values --> Start value

I hope this informations will help you...
