P ERIODIC D ATA R ECORDING
A snapshot of the data is saved periodically at a period programmed by
the register “FDR_Period”, and also when a local warning or fault is
generated. The master controller has a real time clock (optional) that
keeps track of the date and time, so every entry is logged with this time
information. If the “FDR ENABLED” is set to “1”, the master controller
sends a periodic request to all to modules to save their local data to their
FDR memories. If any module has a local fault, it will immediately save it
to its local FDR with the last time information received from the master
plus a “time_increment”, specified in seconds.
