DCU Board block diagram
Operationally the DCU board provides a distributed database
over the CAN-bus. A PC Card is used to transfer new application
definitions from the associated configuration tool to the DCU
system. These parameter files, when properly transferred, are
stored into the DCU FLASH-memories, where they stay regard-
less of powering conditions (power on or off) until erased upon a
user command.
