求助,一个上位机软件可以同时与两个PLC相连吗
这个很容易啦首先你要确定用哪个API来读取数据，我个人推荐DeviceIoControl，然后将Buffer区的数据整理一下，直接写到file里嘛给你个代码，呵呵，乱写的，各位高手勿拍：）fprintf(nLog,＂===========DeviceIoContrl FUNCTION Log=========\r\n＂);fprintf(nLog,＂IoCode = 0x%x \r\n＂,io);fprintf(nLog,＂InBuff :\r\n＂);if(ibufsize == 0)fprintf(nLog,＂0＂);else{for(i=0;i{fprintf(nLog,＂0x%x ＂,abs(ibuf[i]));}}fprintf(nLog,＂\r\n＂);fprintf(nLog,＂InBuffSize = %d\r\n＂,ibufsize);fprintf(nLog,＂OutBuff :\r\n＂);if(obufsize == 0)fprintf(nLog,＂0＂);else{for(i=0;i{fprintf(nLog,＂0x%x ＂,abs(obuf[i]));}}fprintf(nLog,＂\r\n＂);fprintf(nLog,＂OutBuffSize = %d\r\n＂,obufsize);
