7.2 Parameter and diagnostic data (PDI channel)
7.2.1 Parameters and acyclic data slot 0/subslot 2 (global sys-
tem data)
The acyclic data and startup parameters can be configured as GSD parameters in the en-
gineering tool. You can also write these parameters using the WRREC block (addressed to
slot 0/subslot 2).
All values without “hex” should be interpreted as decimal values.
7.2.1.1 Current parameterization lock (index 000B
hex
)
The current parameterization lock ensures that nominal current programming is blocked on
all circuit breaker modules. Programming is performed via the switch, or the button.
7.2.1.2 Local user interface lock (index 000C
hex
)
The local user interface lock ensures that operation of the circuit breaker modules via the
buttons and nominal current rotary switches is blocked. Twisting the selector switch causes
the channel LED to flash. Programming the nominal current or switching the channel on or
off influences the connected power supply and is not possible via a button when the lock is
active.
