18 Application Information
18.1 Storage Media
The operating system and customer application are stored on the internal storage device
(starting from HW2.0).
INFORMATION
At least 1 Gbyte of the total memory must be reserved for the update
process (packages).
To ensure longevity of the memory, writing cyclic data to the internal storage medium
should be avoided (lifespan drastically reduced). For cyclic writing, an external storage
medium (e.g. microSD card or USB stick, depending on the respective device) from
SIGMATEK must be used.
Errors resulting from the use of storage media from other manufacturers are excluded from
support.
18.2 Updating the Operating System
Operating system versions of 09.07.009-387 or below cannot be updated online. For an
update, the memory card must be removed from the device and the image loaded via PLC
Diag - Make Bootdisk.
INFORMATION
With this update process, all existing data on the microSD card are
overwritten! In is strongly recommended to backup import data before
the update process!
