1. INTRODUCTION
The aim of this document is to illustrate how to use the Modbus peripheral supplied in Evoplus
products to interface with a Lon network, using Modbus-Lon interfaces available on the market.
The document presumes that the user has a basic knowledge of LON and Modbus networks.
The Evoplus Circulator supplies the user with a MODBUS RTU peripheral, with RS485 interface.
With some modules on the market it is possible to make the circulator available also to a LonWorks network,
and therefore its status and the possibility of varying the circulator parameters, reading or modifying the
registers as described in the Manual "Instructions for use of the Modbus Protocol" available at the address
"http://www.dabpumps.it/evoplus".
2. MODBUS-LONWORKS GATEWAY
To interface a Modbus and a LonWorks network, a gateway must be placed between the two networks.
There are various types on the market, in particular we recommend the BabelBuster485.
