Status−Dependent And Operating Mode Dependent Lock - Festo CPX Series Manual

5. Parameter
5.2.3 Status−dependent and operating mode dependent lock
Festo P.BE−CPX−CMA X−CONTROL−EN en 0908NH
This lock is designed to protect against maloperations during
the operating phase. It is not permissible to modify para
meters during operation that affect the controller.
To do this, you must change to commissioning mode (or
parametrisation, when using the cyclical I/O data). This data
is documented as commissioning data. Each parameter also
states which operating status is needed.
To write a commissioning parameter
commissioning mode or parametrising mode must be
active,
the controller must be locked (CCON.ENABLE = 0)
