Introduction

iTNC 530 features a comprehensive integral monitoring system for the prevention of input or
operation errors, as well as for identification and diagnosis of technical errors on the control
and the connected units. 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 machine manufacturer can also define specific PLC error messages.
