使用S7-300的仿真程序S7-PLCSIM。
在硬件组台态时,CPU选315-2AG10后下载,一切正常;再添加一PROFIBUS线(DP Master)后再下载,出现以下错误提示:
1 System error.
2 Cannot load SDB 122.
3 he system data cannot be loaded to module
CPU315-2DP(1) - (R0/S2) of station SIMATIC
300 Station.
Look under details or try to determine the
cause for the problem using the diagnostic
buffer of the module.
请高手帮助!
