The Bluetooth interface remains in the “BT_READY” status 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 status “BT_CONNECTED”.
●
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 the selector switch is not possible.
The following graphic chart describes the overall behaviour of the Bluetooth interface:
Figure 48: Behaviour of the Bluetooth interface
[1] Activation of the Bluetooth interface via I/O or fieldbus (value 2) or via the se-
lector switch position OFF (value 3)
[2] Establishment of connection by Bluetooth master
[3] Separation of the connection by the master
[4] Abort by the DCS
[5] Timeout
[6] Abort by the DCS
When changing the parameter value, the Bluetooth interface behaviour pattern in
states “BT_READY” and “BT_OFF” is as follows:
