LONWORKS technology is a network control system concept developed by Echelon Corporation,
L
ONWORKS network provides Local Operating Network that is superior in the distributed control.
Each device works in a peer-to-peer fashion on LONWORKS network. This LONWORKS option is
equipped with the L
ONWORKS Smart Transceiver (Neuron Chip).
2. Names and functions
The drawing below shows names and functions of main parts.
2.1. Service pin
Service pin is used for commissioning device. Use SW2 on the option board.
Danger
Mandatory
Operate Service switch only when a cover for the main circuit terminal is attached.
Otherwise, it may lead to electric shocks.
Operate Service switch using the non-conductive stick. When it is operated with a
conductive stick.
Otherwise, it may lead to electric shocks.
2.2. Use of RS485 communication port
Serial communication (2-wire RS485) option can be used. However, while it is connected, the
internal communication line is switched to RS485 then the communication via L
ONWORKS network
is disabled. In this case, communication error trip time (f803) is also active. Use RS485 serial
communication option specified by Toshiba.
