Initializes the asynchronous mechanism and generates the asynchronous tasks
The method Init is used to initialize the AsyncManager and to create the required additional tasks. The number of required tasks is specified by the parameter GPL.Gc_udiMaxNumOfAsyncTasks.
The method Init must be continuously called until one of the following conditions is true:
oThe output q_xDone indicates True
oThe output q_xError indicates True
For the additional tasks, created by this library, the following conditions apply:
oThe priority for each task is set to 31
oThe name of the task is set to TASK_Async<#> (# is a sequential number starting at 1)
NOTE: For a diagnostic of the method Init, it is possible to evaluate in the message logger if a cycle time overrun occurs because of the call up of the method Init. No filter is set which avoids the indication of the messages.
