Function
When an error occurs in a data
exchange between the CPU Unit
and the Inner Board, the Inner Board
Error Flag (A40208) and the appro-
priate bits in A424 will be turned ON.
The meaning of the bits in A424
depends upon the model of Inner
Board that is being used. Refer to
the Board's operation manual for
details.
A424 will be cleared when the error
is cleared.
When A40213 is ON, the content of
these bits depends upon the status
of A42615 (the Interrupt Task Error
Cause Flag).
A42615 ON:
An attempt was made to refresh a
Special I/O Unit's I/O from an inter-
rupt task with IORF(097) while the
Unit's I/O is being refreshed by
cyclic I/O refreshing (duplicate
refreshing). A42600 to A42611: con-
tain the Special I/O Unit's unit num-
ber.
These bits will be cleared when the
error is cleared.
When A40213 (the Interrupt Task
Error Flag) is ON, this flag indicates
the cause of the error. The CPU Unit
will continue operating and the ERR/
ALM indicator on the front of the
CPU Unit will flash.
A42615 will be ON if a Special I/O
Unit was refreshed from the interrupt
task while it was already being
refreshed.
When an CPU Bus Unit Setting
Error occurs, A40203 and the bit in
this word corresponding to the Unit's
unit number are turned ON. Bits 00
to 15 correspond to unit numbers 0
to F.
The CPU Unit will continue operat-
ing and the ERR/ALM indicator on
the front of the CPU Unit will flash.
When a Special I/O Unit Setting
Error occurs, A40202 and the bit in
these words corresponding to the
Unit's unit number are turned ON.
Bits 00 to 15 correspond to unit
numbers 0 to F.
(Bits A42800 to A43315 correspond
to unit numbers 00 to 5F (0 to 95).)
The CPU Unit will continue operat-
ing and the ERR/ALM indicator on
the front of the CPU Unit will flash.
ON: Duplex Communications Units
for the corresponding unit number
does not exist, i.e., it is not mounted,
the Unit does not support duplex
operation, or the unit number is ille-
gal.
Bits 00 to 15 correspond to unit
numbers 0 to F.
ON: The settings of the pair of Units
mounted for duplex communica-
tions are not the same. Refer to the
Operation Manual for the Communi-
cations Unit for details on settings.
Bits 00 to 15 correspond to unit
numbers 0 to F.
