Abstract

PURPOSE: To enhance the sequence control function and then increase the performance of the controller, by providing several processors having the local memories plus the common memory to carry out an interface via the bus line and at the same time executing the program.
CONSTITUTION: Master processor 2 delivers the request signal to occupy the bus line S to the control part 5 based on the program of the internal memory, and then given an access to the common memory 6 if the request is accepted to then read the sequence instruction to the line S for execution. Then the information is transferred to the common input/output device 9... via the line S, the control part 5 and the line S again while transferring the information with the slave processor 3 and also retrieving the storage information of the external and internal I/O regions in the memory 6 respectively. The processor 3 carries out the initializing process of each part when the power source starts, and then performs the process of the error information written into the memory 6 by the processor 2 plus the process of the parity error which is generated on the line S. Then the processor 2 indicates the start discontinuation of the program to the processor 2.
