Application of SIMENS S7-200 protocol in mechatronical teaching and practice training system

It introduces the modularization design of mechatronical teaching and practice training system. On this base,uses SIMENS S7-200 PPI protocol to integrate all modules,and the module communicates each other in a single host-slave mode.The application result shows that SIMENS S7-200 PPI network can finely satisfy the request for module communication underlying the environment of mechatronical teaching and practice training system.
