Research and application based on RK512 protocal in Impeller Coal Feeder

Paper introduces the frame format of RK512 protocol and SIEMENS point-to-point communication module CP341. According to the control requirement of the Impeller Coal Feeder, proposed the design mind and control flow chart. According to the call of protocol block, paper provided the data extending of the RK512 Protocol. And according to field programming, it is verified that the module CP341 has the advantages of low-cost, high stability and practicability when it be used with the third party equipment under the RK512 protocol for communication.
