Function
Turn this bit ON to restart the RS-232C
port. (Do not use this bit when the port
is operating in peripheral bus mode.)
This bit is turned OFF automatically
when the restart processing is com-
pleted.
Turn this bit ON to restart the peripheral
port.
This bit is turned OFF automatically
when the restart processing is com-
pleted.
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 edit-
ing. The setting of this bit is valid only
when A52700 to A52707 have been set
to 5A.
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 not valid in peripheral
bus mode and only bit 5 is valid in NT
Link mode.)
Bits 0 and 1: Not used.
Bit 2: ON when there was a parity error.
Bit 3: ON when there was a framing
error.
Bit 4: ON when there was an overrun
error.
Bit 5: ON when there was a timeout
error.
Bits 6 and 7: Not used.
These flags indicate what kind of error
has occurred at the peripheral port;
they are automatically turned OFF
when the peripheral port is restarted.
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 overrun
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 oper-
and of the instruction, the system error
given in the operand of the instruction
will be generated instead of a user-
defined error.
