PLC Manager for Incompatible PLCs in a Cell Controller

비호환 기종 PLC들의 통합제어를 위한 PLC매니저 설계

CIM is generally considered as a solution for total automation of a manufacturing system. In a CIM system, Flexible Manufacturing System(FMS) is linked colsely to the actual manufacturing line. This study will examine the strategy of integrating incompatible FA equipments, expecially PLCs (Programable Logic Controllers). PLC Manager is proposed as a model for integrating PLC algorithms, whose primary tasks are to communicate line-field data with PLCs and cell controller. To operate it, a PLC script language is designed and implemented.
