A programmable controller (20) is provided with a label information analysis unit (25), a program execution unit (24), and a label information holding unit (22). A display (10) is provided with a display unit (17), a label information holding unit (12), a diagram display processor (16), and a label information analysis unit (14). When the label information analysis unit (25) determines that a label value is present within a range, the program execution unit (24) executes a processing program that corresponds to the determination result. When the label information analysis unit (14) determines that a label value is present within a range, the diagram display processor (16) acquires, from label information, a message corresponding to a case in which the label value is present within the range, and displays the message on the display unit (17). |
