OPENNET CONTROLLER USER’S MANUAL 26-1
26: LONWORKS INTERFACE MODULE
Introduction
This chapter describes LONWORKS interface module FC3A-SX5LS1 used with the OpenNet Controller to interface with
the LONWORKS
®
network, and provides details on the LONWORKS system setup and the LONWORKS interface module
specifications.
The OpenNet Controller can be linked to LONWORKS networks. For communication through the LONWORKS network, the
LONWORKS interface module is available. Mounting the LONWORKS interface module beside the OpenNet Controller
CPU module makes up a node on a LONWORKS network. The node can communicate I/O data with other nodes in a dis-
tributed network.
LONWORKS Interface Module Features
The LONWORKS interface module conforms to the specifications of LONWORKS that is recognized worldwide as a de facto
industry standard open network, so the OpenNet Controller can be linked to the LONWORKS networks consisting of LON-
WORKS compliant products manufactured by many different vendors, such as I/O terminals, sensors, drives, operator inter-
faces, and barcode readers. The flexible, configurable, and interoperable features of the LONWORKS network make it
possible to build, expand, or modify production lines with reduced cost.
The transmit/receive data quantity can be selected from 0 through 8 bytes (64 bits) in 1-byte increments. One LONWORKS
interface module enables the OpenNet Controller CPU module to transmit 64 bits and receive 64 bits at the maximum to
and from the LONWORKS network.
The network can be configured either in bus or free topology. The total transmission distance can be 1,400m in bus topol-
ogy and 500m in free topology. The free topology makes it possible to configure a flexible network.
About LON
The LON
®
(Local Operating Network) technology is a network control system developed by Echelon, USA. The LON
technology is an intelligent, distributed network for communication with various sensors and actuators at a maximum of
32,385 nodes.
LONWORKS is the open control standard for buildings, factories, houses, and transportation systems. Now, LONWORKS
networks are widely used in major building automation (BA), process automation (PA), and many other industries in the
world.
Communication between application programs installed in LonWorks compliant nodes is performed using the LonTalk
protocol based on the reference model of the Open System Interconnection (OSI) issued by the International Standard
Organization (ISO).
