Network Method for Automation Factory Processor

자동화 공정을 위한 네트웍 구현

As design a network system that should command and response to do tasks by PLC, to make factory automation for being distributed facilities which are not guaranteed procedure, through polling method, commands are send orderly by PLC and responses are answered by each sub-unit. It make a guarantee of sequence and drive a master-slave operation in network. This method help to distribute procedure systems and make possible dividing tasks to each unit. To make this method, network protocol's format have Master or Slave ID and tasking data and Master's command or Slave unit's report. In network interpret algorithm, skip algorithm are included and it make guarantee of protecting data though network are in noise. Data that are made by this method are send to PC to transmit long-distance user by internet.
