PROBLEM TO BE SOLVED: To provide a PLC capable of monitoring an automatically generated execution program. SOLUTION: This PLC has I/O modules 11, 12, a CPU module 2, an input/output bus 3, and a PC 4 having a display 41. The CPU module 2 has a control program storage part 211 storing preliminarily an intrinsic control program packaged with arithmetic processing and input/output information, a library 212 storing preliminarily a function block expressing the arithmetic processing, and a header file 213 storing preliminarily equivalent input/output information expressing equivalently the input/output information by a graphical language. The PC 4 displays the execution program generated and stored in a main storage part 241, on the display 41, by the function block and the equivalent input/output information, referring to the library 212 and the header file 213.
