Third, system debugging Previous page next page
CNC machine tool networking uses serial communication, while serial communication is characterized by information transmitted in one direction, occupying only one communication line. Therefore, this line serves as both a data line and a tie line (except for hardware flow control). , using the direct connection method of the tie line), that is, to transmit both the data information and the contact control information on one transmission line. To identify the contact signals and data signals in the information stream, it is necessary to have a serial communication protocol, that is, an agreement between the two parties, including the provisions of the transmission speed, data format, verification method and control character definition, communication Both parties must abide by it. By modifying the communication protocol, the eXtremeDNC software is suitable for almost all CNC systems.
The system debugging process is actually the process of modifying the controller properties (CSP). Users can find the corresponding communication parameters through the CNC system manual, and then set the “Setting†tab in the eXtremeDNC software to match, mainly set the communication port (CommPort), baud rate (BaudRate), data bit (DataBits). , StopBits, ParityBit, FlowControl. If you are unable to find these communication parameters, eXtremeDNC provides a connection wizard that allows you to detect communication parameters that match the controller.
The second is to set the path of the receiving and sending program (Path), the receiving label (Input), the sending label (Output), the remote request command (Remote), these settings are changed according to the CNC system, but not Complex, because the software itself provides a lot of options, you just have to choose according to the actual situation. When all these parameters are set, the CNC machine can communicate with the computer.
Fourth, the operation and use
After the system debugging is completed, the actual operation is very simple. You only need to open the computer and enter the main interface of eXtremeDNC every time you use it. Since the automatic connection is set, the software automatically connects with all CNC machine tools, and then it can be operated on the machine side. The machine operator does not need to operate the computer.
When the program is output to the computer, select the program to be output, directly use the OUTPUT (or PUNCH, DATAOUT, etc. depending on the CNC system) on the MDI operation panel, and the program will be output to the eXtremeDNC inbox (Inbox).
To call a program on your computer, you need to use a remote request file. The remote request file is actually similar to a simple NC program, which is saved in the program directory of the CNC system after debugging according to the type of CNC system. Each time you use it, change the program name in the remote request file to the name of the program to be called. Of course, the program name must be the name of the program existing in the Outbox, then send the remote request file, and finally use the MDI operation. The IUTPUT (or READ, DATAIN, etc., depending on the CNC system) on the panel is loaded into the desired program.
The following example illustrates the remote call process of the FANUCOTE CNC system:
(1) Open the remote request file O2222.
%
O2222
WWGETP program name WW
M30
%
(2) Modify the remote request file O2222 and change the program name to 3211.
%
O2222
WWGETP3211WW
M30
%
(3) Press the “OUTPUT†button to send the remote request file O2222 to the computer (this file is not saved in the inbox, just send a remote command to the computer).
