RS-232C
Port Error
Flags
These flags indicate what kind of
error has occurred at the RS-232C
port; they are automatically turned
OFF when the RS-232C port is
restarted.
(These flags are valid in Serial Gate-
way mode. They are not valid in
peripheral bus mode and only bit 5 is
valid in NT Link mode.)
Polling Unit:
Bit 5: ON for timeout error.
Polled Unit:
Bit 3: ON for framing error.
Bit 4: ON for overrun error.
Bit 5: ON for timeout error.
These bits can be cleared by a Pro-
gramming Device.
Bits 0 and 1:
Not used.
Bit 2: ON for
parity error.
Bit 3: ON for
framing error.
Bit 4: ON for
overrun error.
Bit 5: ON for
timeout error.
Bits 6 and 7:
Not used.

Code
These flags indicate what kind of
error has occurred at the peripheral
port; they are automatically turned
OFF when the peripheral port is
restarted.
(These flags are valid in Serial Gate-
way mode. They are not valid in
peripheral bus mode and only bit 13
(timeout error) is valid in NT Link
mode.)
Bits 8 and 9: Not used.

error.
Bit 11: ON when there was a framing
error.

run error.

error.

A529 --- FAL/FALS
Number for
System
Error Simu-
lation
Set a dummy FAL/FALS number to
use to simulate the system error
using FAL(006) or FALS(007).
When FAL(006) or FALS(007) is exe-
cuted and the number in A529 is the
same as the one specified in the
operand of the instruction, the sys-
tem error given in the operand of the
instruction will be generated instead
of a user-defined error.
0001 to 01FF
hex: FAL/FALS
numbers 1 to
511
0000 or 0200
to FFFF hex:
No FAL/FALS
number for sys-
tem error simu-
lation. (No error
will be gener-
ated.)
