6. Check the channel-specific log file. To do this, open the file at "<Installation
directory>\WinCC\Diagnostics" in a text editor. Check the latest entries with the "ERROR"
flag. You can find a description of this step under the topic "Description of the entries in
the log file" in the WinCC online help.
7. If the error cannot be located even after checking the log file, contact the Customer
Support Team.
With a client-server system, operator control and monitoring is not usually performed directly
on the OS server. Therefore, the operator control and monitoring functionalities must be
checked with the aid of an OS client.
You need to check the following points in this regard:
● Availability of all OS areas
● Entries in the process control list
● Status of connections
● Perform a picture change and estimate the time required to open a picture
● Lifebeat monitoring/asset management (maintenance station)
● Screen compositions
● Trend compilations for archive and online tags
● Redundancy status of the redundant OS servers
● Distribution of the OS clients to the preferred servers
● Time synchronization
You can find further information in the "SIMATIC Process Control System PCS 7 – Time
Synchronization" (https://support.industry.siemens.com/cs/ww/en/view/109746544)
manual.
● Redundancy settings for redundant OS servers
