First, the remote monitoring terminal quickly downloads the NC code (early a substring) to the local controlled terminal (machine) through the GM data item, and executes the fast code download 90. The local controlled end of the station sends the download back through the STATE data item

Page 13 200416508 V. Description of the invention (9) The message “Confirmation that the download is complete 9 2”, the remote monitoring terminal performs single-step execution of π, π pause execution through the com data item ”,“ clear screen ”and“ leave ”commands or“ Continuously execute the π command to achieve the program control function to control 9 4 or perform continuous operation. At the same time, it can display the real-time processing trajectory map generated by the χ_γ position returned from the wave data item on the local controlled end, and through T ra ν e 1 data The item returns one set of starting position (cur —X, cur_Y) or another set of target position, arc radius, starting horn movement angle (nxt—X, nxt—Y, radius, start_Ang, travel_Ang) The real-time execution planning display and the real-time processing block display generated by the NC code line number returned by the Li neNum data item are used for real-time monitoring, and the monitoring target is indeed achieved. After the execution of the continuous processing is completed, the local controlled end sends back the program execution end message through the STATE data item to confirm that the processing is completed 9 6. To avoid confusion, the computer on which the linear motor control machine is located is called the Local host, and the computer on which the remote monitor is located is called the Remote control host. Both are readable at the same time. And writable (reader / writer). The remote monitoring computer is responsible for writing the control command to the DataSocket server via DataSocket (command DS-SetDataValue) via the CV I human-machine interface, and generates a DS_EVENT_DATAUPD | VTED event to notify the controlled end. The DataSocket in the CVI program executed by the controlled terminal is called automatically by the return function, and executes (instruction DS_Ge t Data Value) the control command to read back the information data (such as ff XCONT ") to determine and execute the corresponding work. Similarly, the controlled computer can determine the actual movement position of the motor read by FlexMotioη through the timer in the CVI, and write the X-Y position data to the DataSocket servo through DataSocket (command DS_SetDataValue).
