32-bit register for storing any type of information. This is a free register available
to the user for 'Read' and 'Write' use. As the information is permanently stored
in EEPROM, it cannot be written to cyclically. The content has no effect on the
control program. It is possible to store a version number or the last commissioning
date in it.
