CPU Bus Unit
Initializing
Flags
These flags are ON while the corre-
sponding CPU Bus Unit is initializing
after its CPU Bus Unit Restart Bit
(A501.00 to A501.15) is turned ON
or the power is turned ON.
Bits 00 to 15 correspond to unit num-
bers 0 to 15.
Use these flags in the program to
prevent the CPU Bus Unit’s refresh
data from being used while the Unit
is initializing. IORF(097) cannot be
executed while an CPU Bus Unit is
initializing.
These bits are turned OFF automati-
cally when initialization is completed.
OFF: Not ini-
tializing
ON: Initializ-
ing
(Reset to 0
automatically
after initializa-
tion.)

Digits
The manufacturing lot number is
stored in 6 digits hexadecimal. X, Y,
and Z in the lot number are con-
verted to 10, 11, and 12, respec-
tively.
Examples:
Lot number 01805
A310 = 0801, A311 = 0005
Lot number 30Y05
A310 =1130, A311 = 0005
