For a detailed analysis we would need more detailed information, e.g. WinCC OA version, operating system and the type of the UI, and some files for the project (log files, config files). As sharing data in the WinCC OA Portal is not that easy it is possibly better when you get in contact with your c...

During the recovery (newer) database directories/files which are missing are copied to the starting WinCC OA project. This not only related to files in the Value Archive directories, it is made for all database directories. If some directories/files must be deleted the deletion is made during startu...

You have to check the configuration of the _address configs in WinCC OA to see if the correct type is used. If no "CP56Time2a" type is used the time stamp is given by the driver. When you need further assistance it is maybe easier when you get in contact with your common WinCC OA support. The WinCC ...

Thanks for replying Leopold, Why do you need an additional function to set the input elements invalid if no heartbeat is received? - I was hoping to use trend tool to display the values as invalid (out of the box trend functionality) in case of connection loss or invalidation of the values (e.g. he...

I do not know how to read the protocol log as it seems not to be log written by WinCC OA. If the timestamp given by the PLC or if the system time is used depends on the configuration of the peripheral address. When you to use the PLC timestamp you have to use a type where the text for the type conta...

In the Event Manager timestamps for original values have to be in the correct ascending time order. Writing an original value with a timestamp older than the time stamp for the last value is not possible. To write older values correction values must be used, as it is done with the driver in your cas...

At _Ui_<num> you must replace <num> with the number for the UI manager you are using. The _Ui datapoints you find at the datapoint type _Ui in the PARA module. In the WinCC OA Documentation you can find information for the _Ui datapoint in the chapter Reference tables --> Internal datapoint types. I...

If a reference contains an object which cannot be rotated the rotation parameter will be ignored when using addSymbol(). I made some tests with a reference containing of rotateable objects and addSymbol(). The rectangles will be a "parallelogram" if the scaling parameters do not have the same value....

There seem to be several problems. At "Direction" you have selected "AM_Output" which sounds like an output and not an input address. In the simulation file you have defined times which shall be used when setting a value. Also you have used the option "-2" which defines that the values will be set i...

In your posting the images are missing.
Maybe you can make a document with the description and screenshots and attach it.

What do you want to do with the simulation driver?
