Indicates where this CPU Unit is
mounted. (Duplex CPU System
only)
Indicates the current mode.
A32808 is turned OFF in duplex ini-
tialization and thus cannot be used
alone to detect errors causing a
switch to Simplex Mode. Use
A32808 together with A43915 as
shown below.
The Duplex Initialization Flag is also
used for write processing in online
editing, when the initialize switch is
pressed, when processing com-
mands from communications or Pro-
gramming Devices, etc.
Indicates which CPU Unit is the
active CPU Unit.
Indicates the system configuration, CS1H CPU Units or
CS1D CPU Units.
A32810 OFF, A32811 OFF:
A32810 ON, A32811 OFF:
A32810 ON, A32811 ON:
ON: The right CPU Unit failed to
recover duplex operation in Duplex
Mode even after the error was
cleared and an attempt was made to
recover duplex operation automati-
cally.
ON: The left CPU Unit failed to
recover duplex operation in Duplex
Mode even after the error was
cleared and an attempt was made to
recover duplex operation automati-
cally.
These flags are ON while the corre-
sponding Special I/O Unit is initializ-
ing after its Special I/O Unit Restart
Bit (A50200 to A50715) is turned
from OFF to ON or the power is
turned ON.
The bits in these words correspond
to unit numbers 0 to 95 as follows:
A33000 to A33015: Units 0 to 15
A33100 to A33115: Units 16 to 31
----
A33500 to A33515: Units 80 to 95
Use these flags in the program to
prevent the Special I/O Unit’s refresh
data from being used while the Unit
is initializing. Also, IORF(097) can-
not be executed while a Special I/O
Unit is initializing.
These bits are turned OFF automati-
cally when initialization is com-
pleted.
These words contain the maximum
value of the differentiation flag num-
bers being used by differentiation
instructions.
