2. About this Document
The purpose of this guide is to describe the installation and operation of a WebdynModbus gateway.
2.1 Scope
The present technical description is valid for WebdynModbus gateways from hardware version 1 onwards,
and from software version V3.04.17 and up.
2.2 Target Audience
This guide is intended for users of WebdynModbus gateways.
2.3 Product Versions
Version 1.0.
2.4 Safety advice
It is essential to respect all safety recommendations featured in this guide.
Failure to comply with these recommendations may cause damage to equipment and danger to the
health safety of personnel.
Electrical connections
• All wiring must be carried out only by a specialized qualied electrician.
• Prior to installation, all equipment connected to the corresponding communications bus must
be disconnected on both sides (DC and AC).
The WebdynModbus unit is liable to damage from electrostatic discharge (ESD). Avoid all contact
with component connectors and terminals.

3. Principles of Operation
The WebdynModbus gateway is the communications hub for your Modbus installation. It continuously
collects desired data from Modbus equipments, concentrates this data into les, and sends these les to
a remote FTP server. In doing so, this gateway enables you to be constantly informed on the operational
state of your installation.
