西门子驱动装置(SIMOVERT MasterDrives VC，MicroMaster 4以及SIMOREG DC Master)具有强大的通讯功能。本文档介绍S7 PLC与驱动装置用PROFIBUS DP协议。
西门子驱动装置(SIMOVERT MasterDrives VC，Master)除了具有与驱动基本应用有关的功能外，为三种方式：MicroMaster 4以及SIMOREG DC还具有强大的通讯功能。驱动通讯可以分
· PROFIBUS DP协议
· USS协议
· SIMOLINK协议（一般用来代替Peer to Peer协议，实现从站到从站的通讯）
PROFIBUS DP和USS协议属于主／从通讯，需要有PLC作为主站，驱动装置作为从站。
USS协议的主要优点是，其接口集成在基本装置中，不需要额外费用；主要缺点是通讯速度慢，只有基本通讯功能(PKW+PZD)，最多31个从站。
PROFIBUS DP协议的主要优点是，通讯速度快，除了基本功能之外还有一些附加功能（例如：非循环通讯，交叉通讯），站点数更多；主要缺点是需要另外购买作为选件的通讯模板（例如：CBP2或PROFIBUS模板）。
SIMOLINK协议（代替Peer to Peer协议）主要用来实现驱动装置与驱动装置之间的通讯。SIMOLINK协议也可以是主／从通讯，主站是S7-400 (FM458+EXM448)或SIMADYN D。
这里主要介绍S7 PLC与躯动装置采用PROFIBUS DP协议进行通讯。
采用PROFIBUS DP协议通讯时，既可以利用STEP 7本身提供的功能，也可以使用TIA软件Drive ES。
