8ABB ARC GUARD SYSTEM™ – TVOC-2-COM MODBUS CONFIGURATION MANUAL

1.1 Introduction

This manual covers the Modbus interface, which offers

a direct connection to Modbus-RTU for the Arc Guard

System™ TVOC-2.

TVOC-2-COM will behave as a slave. This means all

communication will be performed by a master device on

the same Modbus system. Mostly this will be a PLC. This

manual explains how to install the Arc Guard System™

TVOC-2-COM to your Modbus system.

1.3 Quick start-up

1Make sure your Modbus master has been installed to

the system.

2The TVOC-2-COM will be delivered with the following

configuration:

• baud rate 19200

• parity even

• stop bits 1

• Modbus ID 248*

*Modbus ID 248 is not a valid id for a Modbus system but is used to indicate that the

communication is disabled.

3Physically connect the system to the Modbus network.

4Test communication between your master and

the TVOC-2 system. For example see chapter 5

Troubleshooting.
