Function
The Online Editing Disable Bit
(A52709) is valid only when this byte
contains 5A.
To disable online editing from a Pro-
gramming Device, set this byte to 5A
and turn ON A52709.
(Online editing refers to changing or
adding to the program while the PLC
is operating in MONITOR mode.)
Turn this bit ON to disable online
editing. The setting of this bit is valid
only when A52700 to A52707 have
been set to 5 A.
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.
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.
Bit 10: ON when there was a parity
error.
Bit 11: ON when there was a framing
error.
Bit 12: ON when there was an over-
run error.
Bit 13: ON when there was a timeout
error.
Bits 14 and 15: Not used.
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.
