Abstract
PURPOSE: To simplify the partial modification of a program by regarding a series of instruction, relating with each circuit block divided by functions, as an instruction group.
CONSTITUTION: A group of instructions, where each circuit element of the circuit constitution in the virtual sequence figure is expressed as one instruction, are stored in program memory part 3. Instructions stored in program memory part 3 are sequentially read out by arithmetic control part 4. On the basis of an instruction fetched from memory part 3, arithmetic control part 4 performs logical operation as to the logical state of each input line obtained from input fetch part 1 and the output control state at that time so as to decide on a new output control state. In this state, desired sequence operation is realized. Program console part B consists of arithmetic control part 7, memory part 8, input unit 9, output unit 10, and interfaces 6 and 11.
