![]() Send a following string using cnc_download function. 'LF' must be placed at the top of the whole program, and '%' at the end.Īddress 'O' and program number must be placed in the program to be registered.įor example, to register a program such as M code at the end of the program(M02,M30,etc.) NC program to be registered to CNC is a string composed of ASCII characters as the following format. Namely, an error status may refrect the result caused by the previously executedĪnd the error status for some cnc_download callings just before the finish ofĭownloading is returned by "End of downloading NC program". In general, return of errors(EW_DATA, EW_OVRFLOW, etc.) may be delayed. Therefore, the maximum size which can be transferred by one calling is 256 bytes.īecause importance is attached to the speed of data transfer to the CNC, One buffer is used at each cnc_download calling without any relationto the data size. The procedure of downloading is as follows.įor transferring the data, there are 4 buffers of 256 bytes. If an application cannot wait, use the cnc_cdownload function. ![]() This function waits until it can be transferred. When the data processing on the CNC side is delayed and the data cannot be transferred, Outputs NC program to be registered(downloading).
