Description: 西门子仿真编程软件S7-PLCSIM V5.4，用于S7-300/400系列PLC程序的仿真-S7-PLCSIM V5.4 offers the following new features with this release:
DP, Industrial Ethernet and PC Internal connection types supported in addition to MPI
Formerly, S7-PLCSIM used a default connection of MPI, address 2. With S7-PLCSIM V5.4, you can browse STEP 7 projects and select a networked node for establishing a simulation connection. S7-PLCSIM simulates the CPU of the selected node, all nodes that belong to that CPU, and the subnet of the selected node.
Increased number of blocks supported for simulation
S7-PLCSIM supports a set of OBs, SFBs, and SFCs as described in the electronic manual and online help. Of these, some are NOPs that is, they do not perform any operation. With S7-PLCSIM V5.4, the number of blocks that are not NOPs has increased.

Description: S7-200 PLC之PPI协议
通过硬件和软件侦听的方法，分析PLC内部固有的PPI通讯协议，然后上位机采用VB编程，遵循PPI通讯协议，读写PLC数据，实现人机操作任务。这种通讯方法，与一般的自由通讯协议相比，省略了PLC的通讯程序编写，只需编写上位机的通讯程序资源
-S7-200 PLC via PPI protocol of the hardware and software methods of listening, analyzing the internal PLC inherent PPI protocol, then the host computer using VB programming, follow the PPI protocol, read and write PLC data to achieve man-machine task. This communication method, and the general freedom of communication protocols, communication is omitted PLC programming, just the preparation of PC communication program resources
