Why is the ruler not visible for WinCC Tag Logging trend control on the Web Navigator client?
The reason for this is that a Microsoft component is missing. When installing the Web Navigator client from the installation CD, this component is installed automatically. However, if you download the Web client from the Internet / intranet, this component is not installed.
The missing component can be retro-installed as required from the Web server. The path for installation via the Internet Explorer is as follows:
In Web Navigator V1.2 and higher this file is called 'WinSysUpdate.exe'.
This information is also available in the Web Navigator Release Notes under Important Information / Missing MS Components.
