Easy Archive

In line with the data segregation in data classes, an archive can be created separately for each

data area and for each data class.

The data class "System" is an exception. This data is set permanently and becomes effective

at the first installation or a default initialization. For this reason, data backup of system data is

unnecessary, as this data class contains no data created during commissioning or during the

machine run-time.

Protection of the system data

All system data and data contained in the "System" data class in the HMI, NC, PLC and drive

areas may not be affected.

System data cannot be changed through operation, by writing from a part program,

subprogram or cycle and by importing an archive.

When you load user data with a USB FlashDrive, the data volume must not be larger than 4

Identification of archives

Every archive contains the following identifiers:

● Data class: M, I, U

● Type of control: For example 828D ME

● Time stamp: Date and time when the archive was created

● Version designation: Software version with which this archive was created

● Serial number of the system CompactFlash card

These markings allow filters to be set when reading in, determining which archive may be read

in to which control variant, depending on the data class and the software version.
