money. Free topology wiring also simplifies network expansion

by eliminating restrictions on wire routing, splicing, and device

placement. The FT 6000 extends all the benefits of Free

Topology wiring to IP devices, allowing an efficient multi-drop

IP capability where multiple IP devices can be very simply

connected in any topology without the need for switches or

hubs.

The FT-X3 Communications Transformer is a surface mount

communications transformer that is compatible with both

the FT 6000 Smart Transceiver and the previous-generation

FT 5000/FT 3120/FT 3150 Smart Transceivers. The FT-X3

Communications Transformer provides equivalent noise

immunity to both the FT-X1 and FT-X2 Communication

Transformers, the previous-generation communication

transformers. However, the FT-X3 Communications

Transformer is not pin-compatible with the FT-X2

Communication Transformer (which is also a surface mount

transformer). The FT 6000 Smart Transceiver can also be used

with the FT-X1 and FT-X2 Communication Transformers.

Multi-protocol Operation, Future Proofing and

Backward Compatibility

The FT 6000 supports up to four different modes of operation,

as shown in Figure 3, allowing device makers unprecedented

flexibility in creating control devices for a wide variety of

applications using one common development effort. Backward

compatibility and future proofing can both be met using a

common platform based on the FT 6000 family.

The FT 6000 series Smart Transceiver is fully compliant with

the TP/FT-10 channel and can communicate with devices that

use Echelon’s FTT-10/FTT-10A Transceivers, FT 3120/FT 3150

Smart Transceivers, or LPT-10/LPT-11 Link Power Transceivers.

The Neuron core in the FT 6000 series Smart Transceiver uses

the same instruction set and architecture as the previous-

generation Neuron core, including instructions for hardware

multiplication and division. The Series 6000 Neuron core is

source code compatible with applications written for the Series

5000 and 3100 Neuron core. Applications written for the

Series 5000 and 3100 Neuron Core must be recompiled with

the IzoT NodeBuilder Software before they can be used with

the FT 6000 Smart Transceiver.

The FT 6000 series Smart Transceiver uses Neuron firmware

version 21 or later. Firmware versions prior to version 21

are not compatible with the FT 6000 Smart Transceiver. The

Neuron firmware is loaded into RAM from off-chip flash. The FT

6000 Smart Transceiver firmware can be upgraded over the

network.

In the “LonTalk Stack over FT” mode, the FT 6000 runs the

complete LonTalk stack and is fully backward compatible with

devices running the LonTalk stack, including devices based

on the Neuron 3120, Neuron 3150 or FT 3120/3150/5000

Smart Transceiver.

In the “LonTalk IP stack over FT” mode, the FT 6000 preserves

the services offered by LonTalk layers 4-7, replacing layers 2-3

with UDP/IP. This allows the creation of devices that are fully

compatible with LonTalk applications while supporting native IP

addressing at the device level. In this mode, the network layer

has been enhanced to support translation between LonTalk

addresses and IP addresses in a manner that is transparent to

both the LonTalk application above and the FT network below.

This allows LonTalk compatible applications to run unmodified

over Free Topology wiring while gaining IP addressing at the

device level.

In the “BACnet/IP over FT” mode, LonTalk layers 4-6 services

are used to create BACnet/IP devices borrowing from a

rich set of LONMARK® services and profiles. LONMARK

compatible applications can now run unmodified over a very

reliable Free Topology channel, and present their LONMARK

interfaces as native BACnet Objects thus pushing BACnet/

IP all the way down to the simplest of devices. Provisioning

and commissioning of BACnet/IP devices is now possible

with available and powerful LONWORKS commissioning tools.

Devices thus provisioned are fully compatible and discoverable

using industry standard, BTL certified, BACnet management

clients.
