GETCURTASKINDEX
 | Outdated function block This function block is outdated. Use the function GETCURTASKINDEXEX() instead. |
The function block GETCURTASKINDEX determines the task index of the task in which it is currently called.
To differentiate whether the current call occurs in the real-time context or from a cyclic PLC task, see the documentation for the function GETCURTASKINDEXEX. For example, the automatic call of FB_init methods during initialization does not occur from a cyclic PLC task.
