BACnet/IP network uses a non-default UDP port number
other than 47808/0xBAC0, enter this port in the
BACnet/
IP port
field. Enter ‘0’ in this field for switching back to the default setting.
In the field
BACnet/IP mode
the operation mode of the device is selected:
• Device
(Default): In this mode the device operates as a regular BACnet/IP device on the local
network without other advanced features.
• Foreign Device
(FD): In this mode, the device registers at an existing BBMD in the BACnet/IP
network as a foreign device. It is used, if the device is located as a single BACnet/IP device on
a remote IP subnet or behind a NAT router. If operated as a foreign device behind a NAT router,
port forwarding to the BACnet/IP port (UDP, default port 0xBAC0) and optionally to the Web
server and FTP server port (TCP, default port 80 and 21) must be setup in the NAT router.
If foreign device is selected, the following, additional settings must be made:
• FD BBMD IP address
and
FD BBMD port
: IP address and port of the remote BBMD the device
registers at as a foreign device.
• FD re-registration
: A foreign device must periodically re-register at a BBMD. Here you can setup
the corresponding interval. The default is 1800 seconds.
• FD retry timeout
and
FD retries
: Here you can specify the behavior, if registration does not work
instantly. These values should be left at default: 30000ms / 3 retries.
• Broadcast Management Device (BBMD): Same as ‘Device’ but the BBMD function is enabled).
For BBMD-only function, MS/TP can also be disabled.
For debugging purposes, the BACnet/IP port can be disabled independently of the MS/TP port.

(see Section 4.2.7).

port.
4.2.7 MS/TP Configuration
The BACnet MS/TP protocol can be enabled on the device’s port Port1. To enable it, click
the
BACnet MS/TP
radio button as shown in Figure 13. The MS/TP port on the LIP-
ME201 is enabled by default.

Figure 13: MS/TP Configuration.
The MS/TP protocol settings are displayed in the settings box on the right-hand side as
shown in Figure 13. Mandatory settings are the
MS/TP node number
and the
MS/TP
baud rate.
The MS/TP node number determines the physical address of the device on the
MS/TP channel and must be in the range from ‘0’ to the number configured with the
MS/TP max master
configuration option. It must be unique within the MS/TP channel.
The latter parameter defines the maximal number of MS/TP master devices on the MS/TP
channel. The Baud rate on the MS/TP channel can be set to 9600, 19200, 38400, and 76800
Baud.
Important:
All masters on the MS/TP channel must have the same setting for MS/TP max master.
Decreasing the default value 127 of MS/TP max master may reduce latency on the
MS/TP bus.
It is strongly recommended to leave the
MS/TP max info frames
and the
MS/TP max
master
configuration options at their default settings. In any case the
MS/TP max master
number must be high enough to include the highest MS/TP node number of all masters on
the channel. Slave devices may have a higher MS/TP node number than
MS/TP max
master
.
To operate with slow devices on the MS/TP network set the
Network Timing
option to
slow. This increases a number of timeouts, which is needed by some devices, but slows
down network communication. If communication problems occur in standard mode, try
setting the slow mode. For fine-tuning other parameters please refer to Section 6.1.
The
Network Number
of the MS/TP port must be set to a non-zero value in order to
operate the build-in BACnet/IP-BACnet MS/TP router
4.2.8 BACnet BDT (Broadcast Distribution Table)
The BBMD function is needed when a BACnet/IP network spans over several IP subnets
separated by IP routers. If the device is configured as a BBMD, i.e. the BACnet/IP mode is
set to
Broadcast Management Device,
see Section 4.2.6, the BDT (Broadcast Distribution
Table) specifies all other BBMDs of the BACnet/IP network. The BDT is shown in Figure
14.
