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.
