Bit Validator The Online Editing Disable Bit
(A527.09) is valid only when this byte
contains 5A.
To disable online editing from the
CX-Programmer, set this byte to 5A
and turn ON A527.09.
(Online editing refers to changing or
adding to the program while the PLC
is operating in MONITOR mode.) 5A:

A528.07 Serial Port 2
Error Flags These flags indicate what kind of
error has occurred at the serial port
2; they are automatically turned OFF
when the serial port 2 is restarted.
(These flags are not valid in periph-
eral bus mode and only bit 5 is valid
in NT Link mode.)
PLC Link Polling Unit:
Bit 05: ON for timeout error.
PLC Link Polled Unit:
Bit 03: ON for framing error.
Bit 04: ON for overrun error.
Bit 05: ON for timeout error.
These bits can be cleared by the CX-
Programmer.
Bits 00 and 01:
Not used.
Bit 02: ON for
parity error.
Bit 03: ON for
framing error.
Bit 04: ON for

error has occurred at the serial port
1; they are automatically turned OFF
when the serial port 1 is restarted.
(These flags are not valid in periph-
eral bus mode and only bit 5 is valid
in NT Link mode.)

A529 All 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.)

Counter 0
Reset Bit
When the reset method is set to
Phase-Z Software reset, the
corresponding high-speed counter's
PV will be reset if the phase-Z signal
is received while this bit is ON.
When the reset method is set to Soft-
ware reset, the corresponding high-
speed counter's PV will be reset in
the cycle when this bit turns ON. --- Retained Cleared --- ---
