Use

The PXG3… BACnet router connects a BACnet/IP network to a BACnet/LonTalk network (PXG3.L only), and/or a BACnet MS/TP channel. BACnet objects are transmitted simultaneously throughout any and all networks.

Router functions

Four-way routing| The PXG3… BACnet router transmits BACnet protocol between a BACnet/IPv4 network, a BACnet/IPv6 network, a BACnet/LonTalk network (PXG3.L only), and a BACnet MS/TP channel. BACnet objects are simultaneously transmitted throughout any and all networks.
---|---
BBMD| Broadcast Management Device, used to distribute BACnet Broadcast messages across IP Routers.
Web server| The BACnet router includes a Device Object and can be operated by a BACnet Client. Present operating state, date and time as well as statistics on sent packages can be viewed via web server.
MS/TP Slave Proxy| The BACnet router can serve as a Slave Proxy for slaves that are connected to its MSTP port. In other words, it responds to Who-Is messages on the slaves’ behalf by sending an I-Am message.
SNMP v2| Simple Network Management protocol MIB-2, for monitoring and diagnosing the BACnet router network interface.
BACnet NAT| Supports setup of a BACnet network over a NAT device. Additionally, remote access from a public network to BACnet devices is possible on a private network. Important: the public IP address must be static. For security reasons we recommend using VPN tunneling with BACnet NAT.
BACnet/IP to BACnet/IP| When routing between BACnet/IP and BACnet/IP on one IP network, the BACnet router address must be the same on both BACnet networks. The difference is that different BACnet UDP ports are used on the BACnet network.

Communication

• The router complies with BACnet standard and ISO 16484-5.
• A 2-port Ethernet switch allows low-cost cabling via line topology. This is the preferred commissioning medium.
• The LONWORKS network is connected via a 2-pin connection terminal.
• The MS/TP channel is connected via RS485 or a 3-pin connection terminal.
• An RJ45 plug on the device front allows connecting to a PXM20 operator unit (PXG3.L only).
• A USB port is available for connecting the tool.

Engineering

• The router does not require programming. It is configured either using Xworks
  Plus or the Desigo SSA-DNT via Ethernet or using a USB device. For details see SSA (Setup & Service Assistant) Commissioning, CA111050).

• Each device has a unique identification number to ensure efficient commissioning. The number is located on a removable barcode label.

• Each device has a unique MAC address.

For more details see document “Ethernet, TCP/IP, MS/TP and BACnet – Principles” (CM110666).

Installation

Note

Ethernet: See installation manual Desigo TRA, CM111043.
LONWORKS: See installation manual Desigo RXC, CA110336.
HMI (RJ45 plug): only the PXM20 can be connected. Otherwise the PXG3.L or the mistakenly connected device may be damaged.

Mounting

The router is designed for mounting on a standard mounting rail or on a wall. Power is supplied by connecting the plug-in screw terminal blocks.

Commissioning

To prevent equipment damage and/or personal injuries adhere to local safety regulations and related safety standards.

Maintenance

No maintenance required. A supercap supports the real-time clock (3 days).

Disposal

The devices are considered electronic devices for disposal in terms of the
European Directive 2012/19/EU (WEEE) and may not be disposed of as domestic waste.
Dispose of the devices via the proper channels. Observe all local and applicable laws.
