Diagnostic Messages of the Runtime System
Overview
In addition to the listed messages in the section Diagnostic messages, the message logger can display diagnostic messages of the runtime system in Logic Builder and Diagnostics.
These messages have a diagnostic code that deviates from the normal format:
A decimal greater than 1073741824 is displayed as diagnostic code.
The graphic shows the composition of the diagnostic code:
If the decimal diagnostic code of the message is converted into a hexadecimal, then the digit 4 displays in the first place that it is a runtime system message.
