4.1 Introduction
The 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 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.
Moreover, the machine manufacturer can define specific PLC error messages.
