By read access the device provides information about its saving capability.
Bit 0 = 1, the device saves parameters only on command. That means, if parameters
have been changed by the user and no "Store Parameter Command" had been
executed, at the next power on, the parameters will have there old values.
In case of write access the device stores the parameters to the non volatile memory.
This procedure takes approx. 3s. In this time the measuring system isn't accessible
at the bus.
In order to avoid storage of parameters by mistake, storage is only executed when a
specific signature is written to the object. The signature is "save".

On reception of the correct signature, the device stores the parameters. If the storing
failed, the device responds with abort domain transfer, error class 6, error code 6
(hardware fault). See also object 6503h.
If a wrong signature is written, the device refuses to store and responds with abort
domain transfer, error class 8, error code 0.
