WinCC OA Data Quality

[jjang@gtd.eu]

Hi,

How can I read the quality of a input signal? Is there other way to check the quality apart from userbit1?

I want to know if the input signal is valid or invalid. For now, I was investigating the attribute_status.

Thank you

Junho

The attribute 'bad' could be used to determine if the value is valid or not.

When looking at the WinCC OA Documentation you will find a list of all attributes of the _original and _online config in the Chapter Reference Tables --> Data point configs.
The statusbits and their names are described in this list.
