A.Introduction

Terminal definition for LonTalk system

Device CME-LW01 is used for communication interface between Modbus and LonTalk. CME-LW01 needs be configured via LonWorks network tool first, so that it can perform the function on LonWorks network. No need to set CME-LW01 address.

This manual provides instructions for the installation and setup for CME-LW01 that is used to communicate with Delta VFD-E (firmware version of VFD-E should conform with CME-LW01 according to the table below) via LonWorks Network. The content of this instruction sheet may be revised without prior notice. Please consult our distributors or download the most updated
