Behavior of the function block

With each call the function block removes a message from the LogBuffer and transfers it to the Windows Event Viewer.

If the computer uses a write-restricted mass storage medium (typically FLASH DISK), it makes no sense to use the Windows Event Viewer. An MC_AxRtLoggerDespool_BkPlcMc function block can be used to generate a history in any case.
