5.12.3.1 System task information
VAR_GLOBAL
SystemTaskInfo : SYSTEMTASKINFOTYPE;
END_VAR
System flags are implicitly declared variables. Using the Input Assistant, a variable SystemTaskInfoArr can
be found under system variables. This variable is a field with four structures of type
SYTEMTASKINFOTYPE
[
}
58] . The structure definition can be found in the system library. The index in this field is the task ID.
