5.2.3 Status−dependent and operating mode dependent lock
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)
