Sequence controller

Abstract

Abstract PURPOSE:To attain ease of debugging and adjustment of a program, by providing a control section converting the 2nd machine instruction applied with contact control information into the 1st machine instruction stored in a program storage section so as to designated forcedly the contact logic independently of other contact logics of the program. CONSTITUTION:The combination of symbols such as relay contact or coil is inputted from a program input section 1 and converted into a machine instruction train at a machine instruction converting section 2, and stored in a program storage section 5. The stored content is read out to a machine instruction inverting section 4, the machine instruction train is inverted into a relay sequence diagram form and displayed on a program display section 3. On the other hand, a desired machine instruction is extracted from the storage section 5 at an operation processing section 8, the operation is performed based on an external input signal from an input section 7 and outputted externally from an output section 9. Further, a machine instruction rewrite control section 6 is provided between the input section 1 and the storage section 5, and the 2nd machine instruction added to the contact control information is converted into the 1st machine instruction of the storage section 5.
