PREFACE

The purpose of this manual is to enable users to:

 Understand the basics of XVG/eXVG Modbus communications via standard

definitions, interfaces, and protocols.

 Setup Modbus communication with a network of one or more XVG/eXVGs.

It is expected that the user have sufficient knowledge of serial communication and

Modbus protocol. This manual only mentions the relevant information regarding

XVG/eXVG and Modbus, but every attempt has been made to provide sufficient

information for establishing communication with an XVG/eXVG using Modbus protocol.

For detailed information about Modbus protocol, see www.modbus.org.

The following precautions must be considered when writing your own Modbus

application for XVG/eXVG operations:

- Adhere to the tables of registers provided and their allowable data ranges.

- Do not attempt to write to any register if you are not sure of the consequence.

- Do not write to registers that are for options your XVG/eXVG does not have.

Failure to do so can result in erratic control and/or damage to equipment. Care must also

be taken that the process cannot cause damage to property or injury to personnel if the

wrong commands are sent due to operator error or equipment malfunction.
