LonWorks

Intro to LonWorks

LonWorks (local operating network) is a networking platform specifically created to address the needs of control applications. The platform is built on a protocol created by Echelon Corporation for networking devices over media such as twisted pair, power lines, fiber optics, and RF. It is used for the automation of various functions within buildings such as lighting and HVAC

The LonWorks platform is used for many diverse applications that span Smart Buildings, Smart Cities, and the Smart Grid. Chipkin provides LonWorks Gateway conversions to over 150 protocols via the TP-FT/10 channel to other protocols on RS485, RS232, Ethernet, XML, Mbus, etc. port.

FieldServer QuickServer for LonWorks

The LonWorks QuickServer (FS-QS-1XX1-XXXX) is a high-performance, fully configurable, and cost-effective protocol gateway for integrating any LonWorks System. The Gateway comes basic (250 points) and enhanced (500 points) and can connect to serial (RS485 and RS232) and Ethernet ports. Chipkin knows this protocol to source code level – get expert support (Level 1,2) and configuration from day 1.

Chipkin provides LonWorks gateways for a wide number of conversions. For a list, please click here. Or, Please Contact Us for a free consultation.

FieldServer Multiport Gateway for LonWorks

The FS-B3510 is one of the FS-X30 Series FieldServers designed to meet the needs of any system integrator. The FS-B30 Series brings together the powerful FieldServer driver library with state-of-the-art gateway design. It supports 1,000 points which can be updrageded to 10,000 points allowing it to easily handle just about anything with no slowdown in performance.

LonWorks Datasheets, Manuals and specialized terminology

LonWorks has a large number of products and applications with a vast number of specialized terminology. See below for some Knowledge:

Documentation

Jargon Watch

LonWorks – a wide-ranging term generally applied to describe the whole technology developed by Echelon. It is used frequently and ambiguously.

LonTalk – A registered trademark belonging to Echelon. They use it as the name of the protocol used for data communications in a Lonworks system. Ie. It is the brand name protocol. Echelon released this protocol so it could be adopted as a standard – ANSI-approved standard EIA/CEA-709.1-A-1999 – SO/IEC Standard 14908 or European standard EN14908.

Why are LonWorks communications so good?

The communications between all LonWorks devices is done by means of a proprietary chip (The Neuron chip) made according to one design by one company according to one standard which it wrote on its own. It’s obvious that there are so many fewer aspects of the data communications process that can go wrong when there is a single entity involved. When a device vendor implements a Lonworks System Interface he simply has to implement the application layer of the data communication process. For almost all other protocols the device vendor must implement the physical layer, data link layer, the Network Layer, The transport Layer, The Session Layer, the Presentation Layer and the Application Layer. You can see how many more areas of risk there are.

When Echelon released the standard, their license terms required anyone who implements it to implement the full standard. The fact that other vendors can’t cherry pick features and services means that even when implemented by other vendors you still have the same strong chance of success.

Description of the LonWorks Driver

The LonWorks driver allows the FieldServer to transfer data to and from devices using LonWorks protocol. Data transfer occurs via TP/FT10 twisted pair interface with an exhaustive list of protocols including Modbus, BACnet etc. Data transfer is via 2 basic functional blocks, Input and Output allowing Float and Word SNVT data types.

The FS-B30 Series and SlotServer can handle up to 4096 Network Variables, the FS-B2011 up to 1000, and the QuickServer, ProtoNode and ProtoCessor up to 500 which can be of the Standard Network Variable Types (SNVT) and/or User-defined Network Variable Types (UNVT). The FieldServer LonWorks device can be used with explicit and/or implicit addressing and can be bound to a maximum of 15 other LonWorks nodes. The FS-B30 Series can handle a maximum of 4096 explicitly addressed nodes and the FS-B2011 up to 1000. The FieldServer currently supports a default of 63 network variable aliases to avoid network variable connection constraints.

The FieldServer can transfer data (Network Variables) in two ways.

  • It can poll (request data from) other devices at a regular interval.
  • It can send Network Variable Updates
    • At a regular interval
    • When the data has changed
    • In throttled mode using minimum and maximum send time and change on delta parameters.

The FieldServer is capable of being configured by Network Management Tools such as LonMaker. For binding (implicit mode), a Network Management Tool is necessary to create the bindings. It is possible to place a FieldServer into a Network for explicit communications without using a Network Management Tool, but this requires intimate knowledge of the network in question.

The external interface file (.XIF) for the FieldServer can be uploaded from the FieldServer for the particular application. The FieldServer differs from most other LonWorks devices in that its XIF file is not fixed due to varying applications. The list of points available to the network will vary depending on the other networks connected to the FieldServer, and the requirements of the particular application. The recommended procedure for obtaining the XIF file for the FieldServer is to upload it.

The following FieldServer Platforms are LonMark Certified:

  • FS-B20
  • FFS-B35
  • FS-B40
  • FS-SlotServer
  • FS-QuickServerLon
  • ProtoCessor-Lon

The FieldServer provides the capability of defining multiple functional blocks, but only a single LonMark object. The user can create multiple functional blocks or a LonMark object by filling out the Node Self-Documentation String and the respective Network Variable Self-documentation String fields in the FieldServer configuration file.
