摘要: A programmable controller which executes instructions stored in a user program memory to thereby effect predetermined system control. The programmable controller includes a mode designation section for designating a trace trigger mode, an origin instruction input section for inputting an instruction which forms an origin of the trace trigger, an origin instruction memory section for storing the origin instruction inputted from the origin instruction input section, an instruction extraction section for receiving the designation of the trace trigger mode to extract the instruction in coincidence with the origin instruction stored in the origin instruction memory section out of a group of instructions subjected to execution and processing by the instruction execution section, a trace information extraction section for extracting trace information whose reference is the instruction extracted by the instruction extraction section out of a group of instructions subjected to execution and processing by the instruction execution section, a trace information memory section for storing the trace information, and a display section for displaying the trace information stored in the trace information memory section.
