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.

the TVOC-2 system. For example see chapter 5
