Okuma Alarm-D 4203 DNC-B Communication error
Communication error has occurred in the communication protocol A of the host computer.
Code
XXXXXXYZ
XXXXXX:Hexadecimal number of the received command when error occurred. (ISO or ASCII code)
Y:Status of CNC when communication alarm takes place.
0->Operation preparation is not completed.
1->CNC normal status
2->Remote operation status
3->Alarm status
Z:Cause
1->Check sum error has occurred Ne times (parameter set) continuously.
2->Parity error (higher than RS232C) has occurred Ne times (parameter set) continuously.
5->DR signal OFF or no response
6->Reception of unexpected message. (including Ne times of continual reception of [RTY] command.)
9->Reception from the host computer is made when the control is not in response wait status.
Probable Faulty Locations
1)Defective RS232C interface
2)Defective hardware or software of the host computer
3)Mismatch between the actual communication line specification (baud rate, code configuration, etc.) and the communication set by the communication parameters.
Measures to Take
1)Check the hardware and software of the host computer.
2)Change the FRP board or RPP board channel to other channel by setting proper data at communication parameter.
Change the connection of the connector to the proper position,accordingly.
3)Check the following communication specifications between the actual communication line specification and the communication parameters:
RS232C interface channel being used
Parity
Number of stop bits
Transmission code
End code
Baud rate
