Abstract

To operate the automatic devices of manufacturing process more effectively and to solve the needs of the resource sharing, network technology is applied to the unit control devices located in common manufacturing zone and operated by connecting them. This paper introduces a design and test operation of cell system for the management of multivendor PLC by applying to wall paper process based on the manufacturing standardization of CIM. The analysis of designed multivendor PLC group is performed by selecting the parameters such as variation of data packet size and node number of PLC ladder logic program and variation by analyzing the corresponding variation values of token rotation time and waiting time for the system operation. For the method of the analysis. The equation is derived considering the overhead such as indicated packet service time and transmission safety margin for PLC network connection in M/G/I queue model, and it is applied to the cell system and PLC group management for operation. Through the experiment, it is found that the realtime processing is possible with expanded and better result than the result obtained by Jayasumana, Browaka with PLC scan time considered, response lower limit of 10~20 msec. data packet size not more than 50 byte, and the number of node less than 40.
