When changing the parameter value, the Bluetooth interface behaviour pattern in
“BT_READY” and “BT_OFF” states is as follows:

BT_READY1 (switched on)BT_OFF0 (switched off)
BT_OFF2 (fieldbus or I/O)BT_OFF0 (switched off)

tion OFF)

BT_OFF3 (selector switch posi-
tion OFF)
BT_READY or BT_OFF2 (fieldbus or I/O)
BT_OFF0 (switched off)BT_READY or BT_OFF3 (selector switch posi-
tion OFF)
BT_READY1 (switched on)BT_READY or BT_OFF3 (selector switch posi-
tion OFF)
BT_OFF2 (fieldbus or I/O)BT_READY or BT_OFF3 (selector switch posi-
tion OFF)
If the Bluetooth interface is in “BT_CONNECTED” state, a change of parameter value
does not cause a status change. In order to change the status, the master must
interrupt the connection or the connection must be interrupted otherwise:

Timeout for Bluetooth activation
The time the Bluetooth interface remains in “BT_READY” state after activation via
“selector switch position OFF” or after connection abort by the Bluetooth master, can
be set via parameter .
