1: GENERAL INFORMATION Introduction This chapter describes general information about the LONWORKS network system and provides the features and functions of the SX5L communication terminals. LONWORKS Network LONWORKS refers to the whole multi-purpose network technology developed by Echelon Corporation to provide solutions for building and home automation, industrial, transportation, and public utility control networks.
1: GENERAL INFORMATION LONWORKS Device and Functional Block The following figure illustrates examples of LONWORKS devices. Device A consists of switches to send the ON/OFF status signals of three switches to the network when they are operated. Device B consists of two lamps which go on or off when receiving ON/OFF signals from the network.
1: GENERAL INFORMATION place, called an alias table, to store the second and subsequent selector addresses. The allowable quantity of selector address entries for the alias table depends on the type of the device. The maximum quantity is 62 according to the LONWORKS specifications. For the quantity of address table entries of the SX5L, see page 4-1. When using the LonMaker Integration Tool for binding, the tool automatically assigns the selector addresses.
1: GENERAL INFORMATION SX5L Communication Terminal Models and Features The SX5L is a terminal block type LONWORKS I/O device available in a variety of models designed for multi-vendor building automation and industrial control networks. All SX5L communication terminals contain Standard Network Variable Types (SNVTs) defined by the LONMARK Interoperability Association.
1: GENERAL INFORMATION Finger-safe Spring-up Terminal Block Features Time saving The innovative terminals on the SX5L series use special, spring-loaded screws. This makes installation as easy as pushing down and turning with a screwdriver. Installation time is cut in half since the screws do not need to be backed out to install wiring. Screw terminals accept bare wire or ring or spade connectors. Finger-safe The screws are held captive once installed and are 100% finger-safe. 1.
1: GENERAL INFORMATION System Setup Examples Bus Topology Nodes are connected to one trunk line. The trunk line can be extended up to 1,400 meters. Terminators are needed at both ends of the network. Node Node Terminator Terminator Node Node Maximum trunk cable length: 1,400 meters Free Topology The network can also be connected in star, loop, bus, and combination of these configurations. The network can be expanded and modified flexibly. One terminator is needed at any place on the network.

3: INSTALLATION AND WIRING Introduction This chapter describes the methods and precautions for installing and wiring the SX5L communication terminals. Before starting installation and wiring, be sure to read “Safety Precautions” in the beginning of this manual and understand precautions described under Warning and Caution. Mounting on DIN Rail Warning • Turn off the power to the SX5L before mounting and removing. Failure to turn power off may cause electrical shocks or fire hazard.
3: INSTALLATION AND WIRING I/O Wiring Warning • Turn off the power to the SX5L before wiring the I/O and network cable. Failure to turn power off may cause electrical shocks or fire hazard. Caution • Prevent metal fragments and pieces of wire from dropping inside the SX5L housing. Put a cover on the SX5L module during wiring the I/O and network cable. Ingress of such fragments and chips may cause fire hazard, damage, or malfunction.
3: INSTALLATION AND WIRING Network Cable Wiring Caution • Do not run the network cable in parallel with or in the vicinity of power, output, or motor lines. Keep the network cable away from noise sources. Check for loose connection periodically. Loose connection may cause overheat, resulting in possible fire hazard. Applicable Cables Use twisted pair cable with core wires of AWG24 to AWG14 (0.2 to 2.5 mm2) applicable to the LONWORKS network.
3: INSTALLATION AND WIRING Removing the Detachable Terminal Block Warning • Turn off the power to the SX5L before removing and installing the detachable terminal block. Failure to turn power off may cause electrical shocks or fire hazard. To remove the detachable terminal block from the SX5L module, squeeze both latches on top of the terminal block inward to unlock the terminal block from the socket.
4: SOFTWARE SPECIFICATIONS Introduction This chapter describes the software specifications of the SX5L communication terminals.

APPENDIX Introduction This chapter describes type numbers of the SX5L communication terminals and accessories, and also provides a glossary of major terms related to LONWORKS. Type List SX5L Communication Terminal Type Number Power Voltage Module Name Digital Input 24V DC Digital Output 24V DC Digital I/O 24V DC I/O Points Type No.
APPENDIX Glossary Alias When binding network variables, binding may not be completed due to the limitations on selector numbers which are automatically assigned by the management tool. Alias is a technique used to virtually divide one network variable into several variables. Application program A program for the application layer in the OSI reference model, written in Neuron C which is derived from ANSI C.
APPENDIX Network management tool A tool used to perform network management. Network variable A data item that a particular device application program expects to get from other device on a network (an input network variable) or expects to make available to other devices on a network (an output network variable). Examples are a temperature, switch value, and actuator position setting. Neuron Chip A microprocessor that supports LonTalk protocol.
APPENDIX SNVT_switch SNVT index 95. The SX5L uses SNVT_switch mainly for digital input and output statuses. When the input variable has (state) = 1, digital output is on. When (state) = 0, digital output is off. When the digital input is on, an output network variable is sent with (state) = 1, (value) = 1. When the digital input is off, an output network variable is sent with (state) = 0, (value) = 0.
