| 摘 要： | SIMATICS7系统处理用PROFIBUS—DP网络连接的分散I／O外围设备的方法与处理本地连接在中央机架或扩展机架上的I／O模块方法极为相似，根据用HWConfig程序硬件组态时所分配的地址，输入／输出数据通过过程映像直接交换或通过I／O存取命令进行交换。对于连续的数据则不能交换，这就必须使用DP从站的连续的输入／输出数据区域和特殊的功能。

| Abstract: | It is very similar for SIMATICS7 system to deal with the PROFIBUSDP network connective dispersive I/O peripheral equipment and the I/O module of the local center or extended slot. when dealing with thePROFIBUSDP network connective dispersive I/O peripheral equipment, Input/Output datas are exchanged through process reflex or I/O command by the address which is assigned for HWConfig program configure hardware. For continuous data is unable to exchanged,we must use the input/output continuous area and special functions of DP Slave |
