Process Data & Interface Structures
A separate set of Process Data is used for each task :
In: Out: AuxOut: AuxIn:
For External input signals Output of main data or technological relevant external data Output of interim results, diagnostic or internally relevant data Input of configuration values and parameters
This task is used to control sequences within a package. (Cyclically- and Event Triggered)
This task is used for safety checks and initiating of safety actions caused by abnormal conditions. (Cyclically Triggered)
XxxTsk:
In this module the code for this tasks functioBiblioteka ality is situated.
XxxTskOut (Output Interface):
Write external data like signals to the field, or signals to other packages (Fast RDS, RFM, SHM, Messages). Do not pass values to another tasks in this package through the Output Interface module.
This task is used for fast control loops. (Cyclically Triggered)
This task is used for evaluation of the reference values within a package. (Cyclically Triggered)

AppEv AppLp AppRef AppLgc AppSaf AppAnc
Standard Application Program & Task Structure
The task AppEvent is used to read configuration parameters for a package. The data are written independent of the communication mechanism like RDS or Config-Server. (Event Triggered)
The implementation of further substructures is recommended if the data overview will be improved, or the software implementation will be simplified.
Note: The configuration parameters for a task are accessed directly via the Process Data of the AppEv, e.g. PdEv.In.AuxRef.Xyz

XxxTsk
XxxTskOut
XxxTskIn (Input Interface):
Read external data like signals from the field, or signals from other packages (Fast RDS, RFM, SHM, Messages). Do not pass values from another task in this package through the Input Interface module.
Remarks: In the uppermost level of the above mentioned modules (In, AppXxx and Out), direct access of Process Data Images of another task is allowed. Tsk specifies the function of the task within the application according to standard task structure

XxxEvIn
x => PdEv.In.AuxRef.x y => PdEv.In.AuxSaf.y
This task is used to do low prior calculations and to write data which are required for the Engineer HMI. Depending on the communication mechanism the values are written to different variables (RDS or resource global variables). (Cyclically Triggered)
