• Redirect HTTP to HTTPS
• HTTPS only
• HTTPS and HSTS

Use DHCP

If selected DHCP (Dynamic Host Configuration Protocol) is used to automatically configure the device port.

Note
Use DHCP is the default setting for newly added devices. You can still choose to manually enter the IP address in a second step, even if the check box is selected.

IP address start

The first numerical label that is assigned to the device port.

IP address end

The last numerical label that can be assigned to the device port.

Subnet mask

Specifies the subnet within the larger network.

Default gateway

Specifies a node on a TCP/IP network that serves as an access point to another network.

Preferred DNS server

The address of the preferred domain name server. Routing information used for cloud connection if DHCP server is not available.

Alternative DNS server

The address of the alternative domain name server. Routing information used for cloud connection if DHCP server is not available.

Domain name

Name of the domain e.g. siemens.net. When a domain is set up, the devices can be addressed with the domain name, for example AS_01.siemens.net.

Specifies the rate at which data is sent to the bus. Default is 38400 to 76800.

• 9600
• 19200
• 38400
• 76800
• 115200

Network number

Number that identifies the network.
Range 1‑65534. Default is 1.

Auto addressing

When activated the following MAC address settings are obtained automatically:

• MAC address start
• MAC address end

Start MAC address

The first MAC address for the MS/TP port.
Range 0‑127. Default is 1.

End MAC address

The last MAC address for the MS/TP port.
Range 0‑127. Default is 127.

Max manager address

Set the Max manager address to prevent the passing of the token to unused MAC addresses situated after the manager.
Range 1‑255. Default is 127.

Max info frames

The maximum number of information requests to other devices.
Range 1‑25. Default is 10.

Enable large frames

Extends the frame length in MS/TP trunk of router.

Max APDU length

Specifies the maximum length of the APDU for network devices in Bytes. The following values are available:

• BACnet LonTalk = 206
• BACnet MS/TP = 480
• BACnet/IP, no fragmentation = 1024
• BACnet/IP = 1476

Device name prefix

Enter a default prefix and a number for the leading zeros for newly created devices.
Autonumbering – Name pattern

Device description

Type a description and a number for the leading zeros for devices.
Autonumbering – Name pattern

Start of name index

The first index number for the device when connected to the network.

Name index end

The last index number for the device when connected to the network.

UDP Port

Specifies the UDP port in hexadecimal format from BAC0 to BAD4. Default is BAC0.

Network number

Specifies the network number

Local broadcast UDP port

UDP port for local broadcast setting (Default 0xBB02 = 47874). Local broadcast UDP is used for messages that do not need to be routed by BBMD, for example, for grouping commands.

Max APDU length

Specifies the maximum length of the APDU for network devices in Bytes. The following values are available:

• BACnet LonTalk = 206
• BACnet MS/TP = 480
• BACnet/IP, no fragmentation = 1024
• BACnet/IP = 1476

Enable

Select to enable the WLAN port via the out-of-service BACnet property.

SSID

Select the SSID used by the WLAN port of the device.

The different options for SSID are the following:

• Device default
• Name
• Description
• Hostname
• Project name

Password

Set the password used by the WLAN port of the device. Max. 63 characters.

To set the password to factory settings, chose Device default from SSID options list and confirm with Set to factory settings. To view the default factory settings, scan the QR code on the device.

QR code information: WIFI:S:PXC4.E16_0000550;T:WPA;P:1400052738;;
Then SSID = PXC4.E16_0000550 and password = 1400052738

Determine manually: Use the information from the Date/Series/SN block:
Date/Series: 20190423A0000550, S/N: 1400052738
SSID = <ASN>_<Consecutive number after the series letter> and password = <S/N>

Channel

Set the channel used by the WLAN port of the device.

Network number

Default network number when enabling secure connect port. Default is 55189.

Connection timeout

Set the time limit before the connection attempts will be interrupted. Default is 10 s.

Disconnect timeout

Request for disconnect from one device to another. After the specified time without answer the device considers that it is disconnected already. Default is 10 s.

Min. reconnect timeout

Set the time limit before a reconnection attempt after a connection timeout. Default is 30 s.

Initiating heartbeat timeout

If there is no communication for the specified time it will trigger the heartbeat request message to verify the connection is still active. Default is 30 s.

TLS mode

Defines which TLS version is used:

• Flexible
• V1.2
• V1.3

UDP port

Specify the default BACnet UDP port for primary hubs. Default is 0xBAC5.

Network number

Specify the IP network number for nodes/failover hubs. Default is 123.
