Introduction

iTNC features a comprehensive integral monitoring system for the prevention of input or
operation errors, as well as for identification and diagnosis of technical defects on the control
and the connected devices. The monitoring system is an integral component of the iTNC
hardware and software and is active as long as the control is switched on. The presence of a
technical fault or an operation error is made known through a plain-language message.
The effect of the monitoring functions is described in the annex -- .> See "Annex: Monitoring
Functions" on page 3 – 661.
