有一篇文章，前言是：
With Siemens’ introduction of their SIMATIC S7-300 and S7-400 families of PLCs, they’ve established a new network protocol specifically for the S7-300 and S7-400 PLCs. You can use this network protocol to communicate through the PLC’s MPI port without the use of a Siemens Profibus CP.
However, if you desire faster communications, you will need to add a Profibus CP to the PC. Siemens offers communication processors for the L2 network (CP 342-5 DP for S7-300 PLCs) and for the Industrial Ethernet network (CP 443-5 for S7-400).
The L2 network uses the same media and the same first layer of the Profibus network. The Industrial Ethernet network works in the same way as the Ethernet network. That is, you can use the Industrial
不知是否有用。
