•
When an error occurs at the serial port 2 or built-in
RS-4
8
5 port, the corresponding error bit is turned
ON.
•
The flag is automatically turned OFF by the system
when the serial port 2 or built-in RS-4
8
5 port is
restarted.
•
In NT link mode, only bit 1
3
(timeout error) is
enabled.
•
In Serial PLC Link mode, only the following bits are
enabled.
Errors at the Polling Unit:
Bit 1
3
: Timeout error
Errors at Polled Units:
Bit 12: Overrun error
Bit 11: Framing error
Bit 10: 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.
