Upon completion of the auto-tuning, the new values of the parameters Kp, Ti and Td are
calculated and the flag AT completed becomes 1.
If Start AT = 0, the flag AT completed = 0 as well.
If you set Start AT = 0 before the completion of auto-tuning, the auto-tuning is stopped,
the flag AT completed becomes 0 and no new coefficients are calculated.
During the auto-tuning, a test signal limited by parameters Output max. and Output min.
is applied to the output Pwr.
Note: If the maximum gain is not sufficient to reach the setpoint, the auto-tuning cannot
be completed and will continue until it is stopped with Start AT = 0.
6.3 Project macros
Macro is a function block created like a main program in a separate workspace.
To create a new macro:
 use the menu item File > New macro (sect. 6.3.3) or
 select blocks in the main workspace and use the item New macro from the work-
space context menu (sect. 6.3.4)
To use the macro in the project, drag-and-drop it from Library Box into the main work-
space.
