14.7.6 Configuring 'Standby visibility' for the management station
'Station' can be assigned to a
'Standby visibility for Management station'. If the
management station fails, the assigned 'Station' automatically receives this
visibility.
You will find information on configuration of the standby view for management
stations in chapter 'Standby visibility [
14.8 BACnet device configuration
14.8.1 'BACnet device object' –Overview
'Station' contains a 'BACnet device object' element in the tree view of the
'Network' task card. It is used to identify the 'Station'in the
BACnet.
●
In the 'Overview' tab of the detail editor, the 'BACnet device object' element
contains an address and a predefined customer text ('Own device'). The
address is used directly as a 'BACnet device ID' and must be in the same
address range that has been entered in the global settings for BACnet.
●
The configuration of the BACnet stack, including the BBMD function and the
properties of the device object for BACnet transaction control, can be found in
the 'Details' tab of the detail editor.

14.8.1.1 BACnet transaction control
The following properties of the 'BACnet device object' must be set in all stations
and be consistent for the entire
site.
●
'APDU timeout'
Defines the timeout for the BACnet transaction control.
●
'APDU segment timeout'
Defines the timeout for the requirement of another part of a segmented BACnet
message.
●
'No. of APDU retries'
Defines the maximum number of repetitions for a BACnet transaction.
14.8.1.2 Configuration of the BACnet communications stack,
including BBMD function
As a rule there is just one value that has to be defined on all stations:
●
'BACnet UDP port'
Defines the number of the UDP port used for BACnet communication. The
default 47808 (0xbac0) corresponds to the standard. All participants, including
the BACnet clients, must use the same number.
The BBMD configuration in contrast needs only be made for one station per IP
sub-net. If using stations on the Ethernet this must be agreed with the BACnet
clients if they are in the same IP sub-net.
