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 paraĆ
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
ć commissioning mode or parametrising mode must be
active,
ć the controller must be locked (CCON.ENABLE = 0)
