BT_READY
The Bluetooth interface is activated and waits for connection set-up by a master.
The Bluetooth LED (blue) of the local controls is blinking.
BT_CONNECTED
The Bluetooth interface is connected to a master.The Bluetooth LED is permanently
illuminated.
Properties of the input signals:
●
The inputs are edge triggered.
●
The Bluetooth interface is activated with rising edge.
●
The Bluetooth interface is deactivated with falling edge.
Information
For details on the process representation, please refer to Manual (Device integration
Fieldbus).
If the parameter Bluetooth corresponds to the value “2” or “3”, the Bluetooth interface
is in “BT_OFF” status when switching on the device.
By activating the Bluetooth interface, the status will change from “BT_OFF” to
“BT_READY”.The duration for the interface to remain in “BT_READY” state depends
on the selected parameter value.
Parameter value 2 – fieldbus or I/O
The Bluetooth interface remains in “BT_READY” state until a connection is
established. Exception: In case a master was already connected, the status will
change to “BT_OFF” once the set time is exceeded.
Parameter value 3 – selector switch position OFF
The Bluetooth interface remains in the “BT_READY” state until the set time is
exceeded. Once the set time is exceeded, the status will change to “BT_OFF”.
If a Bluetooth master tries to connect within the set time, the connection will be
established.The interface will then change to the “BT_CONNECTED” state.
●
Generally, the status is always signalled either via fieldbus or via I/O interface.
●
The Bluetooth interface may at any time be interrupted via the fieldbus or the
I/O interface.The status will then directly change to “BT_OFF”.
●
Deactivation via local controls is not possible.
The following graphic chart describes the overall behaviour of the Bluetooth interface:
