13 Data media and file management of the iTNC 530 HSCI
13.1 Introduction
Depending on the main computer, the HDR hard disk or the SSDR solid state disk is used as a data
medium.
The data medium of the iTNC 530 HSCI contains the TNC and PLC data as well as all NC software.
Depending on the operating conditions (e.g., vibration load, dirt), the HDR hard disk is exposed
to more or less strain. HEIDENHAIN therefore recommends to have the HDR inspected after
3 to 5 years.

Removing and inserting the SSDR
--> See ”Exchanging the SSDR” on page 29 – 537.
Main computer Data medium Size (in 2011)
MC 6222 SSDR (Solid State Disk Removable) TNC: > 21 GB
PLC: 1 GB
SYS: 2 GB
MC 6241 HDR (Hard Disk Removable) TNC: > 138 GB
PLC: 1 GB
SYS: 2 GB
Defects in the data medium may have the result that no functions can be called any more.
As the entire NC software is on the HDR or SSDR, these hard disks are subject to export
restrictions!
