CPU PLC APPARATUS FOR CONTROLING PROGRAMMABLE LOGIC CONTROLLER SYSTEM HAVING MULTI CPU MODULE

摘要

The present invention relates to a control device for a PLC system. According to the present invention, when a control request for data processing of a register in which the control right status information of the multi-CPU module is recorded is received, the control right is dynamically allocated to the multi-CPU module by referring to the control right status information of the register, and It is characterized in that it comprises a control right setting unit for setting the control right of the CPU module and a bus for transmitting and receiving data between the multi-CPU module and the function module according to the setting of the control right. According to the present invention, there is an advantage in that resources of the PLC system can be efficiently distributed and data processing efficiency can be improved.
