do so, the user creates an application-specific parameter set using the SOPAS ET
configuration software, or edits the parameter set later as required. The user then loads
the current parameter set into the permanent parameter memory of the device.
Memory organization for parameter set
The following diagram shows the memory organization scheme for the internal and
external components involved:

main memory of the

the device 7

NOTE
As part of a data backup plan, always save the current parameter set outside the
device memory. This makes it easier, if necessary (device failure, etc.), to restore, to a
replacement device of the same type, the current parameter set used to date.
External data backup: option 1
To back up the data outside the device memory, the current parameter set can be
manually saved and archived to the computer as a project file (*.sopas file with config‐
uration data). This is the generally recommended procedure.
External data backup: option 2
The prerequisite for automatically backing up the current parameter set data outside
the device memory is to have an additional external storage medium. The device
can optionally be permanently connected to a MicroSD memory card as an external
parameter memory.
