2. Communication hardware introduction The network adopts the dedicated communication serial port HUB produced by COMTROL, and the communication rate per port can be up to 230kBPS, and all ports can reach 115kBPS at the same time. It can connect multiple CNC machine tools through multiple serial port interfaces (RJ45 female port), and can be connected to the HUB or server of the CAD network through the Ethernet 10/100 Base-T device interface. 3. Network connection Install the eXtremeDNC software on a PC on the local network as a communication server, connect the multi-port HUB of COMTROL and the network card of the computer, and then lead multiple RJ45 lines to the RS232 port of the machine by the multi-port HUB, and change the RJ45 line sequence to DB25. Wire sequence and connect to the RS232 port of the machine. The transmission distance of the shielded Category 5 twisted pair cable can reach 100m, and the long line driver can be used over 100m. Third, system debugging 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 (Comm Port), Baud Rate (Baud Rate), data bit ( Data Bits), Stop Bits, Parity Bits, Flow Control. 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.
