NOTE
As part of a data backup plan, we recommend also saving 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 man‐
ually saved to the PC as a project file (*.sopas file with configuration data) thereby
archiving the 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 an external parameter memory for this pur‐
pose.
This can be achieved in one of the following ways, depending on the device:
a) By inserting a microSD memory card with sufficient storage capacity into the
device
b) By connecting a CDB or CDM connection module to the device. The connection
module is equipped with a CMC600 parameter cloning module.
c) By connecting the device to a CDF600 fieldbus module and operating it in proxy
mode.
d) If necessary, by using a combination of a) plus b) or c)
NOTE
Only option a) is possible for the RFU61x.
Operating principle
The user saves the current parameter set to the permanent parameter memory of the
device using the “permanent” option. The device then automatically also saves the
parameter set to an external, permanent parameter memory. Depending on the device
and configuration, this could be either to a memory card, in the CMC600, in the
CDF600 or, when using one of the supported combinations, in both storage media (see
above).
At each restart after being switched on, the device automatically loads the compatible
parameter set from the external storage medium into its working memory and into its
internal, permanent parameter memory. The parameter set is loaded either from a
memory card or, depending on the configuration, from the CMC600 or CDF600.
In the event of device failure, for example, this approach enables the device to be
quickly and easily replaced with another device of the same type provided the above
prerequisites have been met. This is achieved without any loss of configuration data,
and without having to connect the PC to the SOPAS ET configuration software.
