When the serial port 1 or built-in
RS-232C port is being used in NT
link mode, the bit corresponding to
the Unit performing communica-
tions will be ON. Bits 00 to 07 corre-
spond to unit numbers 0 to 7,
respectively.
ON: Communicating
OFF: Not communicating
Read • Cleared when power is turned ON.
• Turns ON the bit corresponding to the unit number
of the Polled Unit that is communicating via the
serial port 1 or built-in RS-232C port in NT link
mode or Serial PLC Link mode.
• Bits 00 to 07 correspond to unit numbers 0 to 7,
respectively.

Restart Bit
A526.00 Turn ON this bit to restart the serial
port 1 or built-in RS-232C port.
Read/write • Cleared when power is turned ON.
• Turn ON to restart the serial port 1 or built-in RS-
232C port.
Note The bit is automatically turned OFF by the
system when restart processing has been
completed.
Serial Port 1/Built-in
RS-232C Port Error
Flags
A528.00 to
A528.07
When an error occurs at the serial
port 1 or built-in RS-232C port, the
corresponding error bit is turned
ON.
Bit 0: Not used.
Bit 1: Not used.
Bit 2: Parity error
Bit 3: Framing error
Bit 4: Overrun error
Bit 5: Timeout error
Bit 6: Not used.
Bit 7: Not used.
Read/write • Cleared when power is turned ON.
• When an error occurs at the serial port 1 or built-in
RS-232C port, the corresponding error bit is turned
ON.
• The flag is automatically turned OFF by the system
when the serial port 1 or built-in RS-232C port is
restarted.
• In NT link mode, only bit 05 (timeout error) is
enabled.
• I
n Serial PLC Link mode, only the following bits are
ena
bled.
Errors at the Polling Unit:
Bit 05: Timeout error
Errors at Polled Units:
Bit 04: Overrun error
Bit 03: Framing error
Bit 02: Parity error
Note If the error occurred in Serial PLC link mode,
the console will retry before communication
establish. Rehabilitation of the communica-
tions is no need for port restart. If user elimi-
nates error, the communication will
automatically establish between console and
servo.
However, error flag will be saved as the
record. If you want to clear the error flag,
please restart port.
