  • Peripheral device of programmable logic controller
    Patent number: 8060221
    Abstract: A tracing-result optimization processing unit generates an optimized tracing result. A tracing-result collation processing unit collates the optimized tracing result and a time chart as a basis of a sequence processing for an external apparatus and detects shift of the optimized tracing result. A tracing-result storing unit accumulates and stores therein a tracing result obtained by a programmable logic controller at predetermined time intervals. Every time the tracing result is stored in the tracing-result storing unit, the tracing-result optimization processing unit generates the optimized tracing result.

  • PERIPHERAL DEVICE OF PROGRAMMABLE CONTROLLER, METHOD OF VARIABLE SUBSTITUTION, AND COMPUTER PROGRAM PRODUCT THEREOF
    Publication number: 20100161085
    Abstract: A peripheral device of a programmable controller for converting an existing program into a program with variables substituted therein. The peripheral device includes a variable-information creating unit and a substituting unit. The variable-information creating unit extracts an address from the existing program, assigns a unique variable to the address, and creates variable-correspondence information on correspondence between the address and the variable. The substituting unit substitutes the variable for the address to convert the existing program into the program with variables substituted therein.
