is preserved for
approximately 20 days (at 25

4-6-2 Reading Error Statistics
Each
time an
error occurs, the ID Controller increments the subtotal for the given
type of error. MCBF figures are also calculated simultaneously, and up to 999
data
items are stored in the designated memory area. The error statistics
read
command enables supervision of error occurrence conditions, and therefore
makes
it possible to perform system operation condition diagnosis on a regular
basis.
