Abstract

PURPOSE:To realize a high-speed operation of a sequence control, by installing an arithmetic circuit exclusive for sequence operation of 1 bit for a high-speed operation plus an arithmetic circuit containing a microprocessor which performs a numerical operation. CONSTITUTION:The sequence controller consists of the 1st arithmetic circuit 10 including the instruction register IR11, logic arithmetic circuit LU15 and others, the 2nd arithmetic circuit 20 including the microprocessor MP21 plus the memory device 30 including the sequence program memory PM31, operation result memory RM32 and others. These devices are connected to each other via the address buses shown by the black thick lines and the data buses shown by the white thick lines each. For such sequence device, only the high-speed 1-bit sequence operation is carried out through the circuit 10. And other operations are carried out through the circuit 20. As a result, the system can be simplified with a reduction of hardwares.
