摘要

The programmable controller (20) includes a label information analyzing unit (25), a program executing unit (24), and a label information holding unit (22). The display unit (10) includes a display unit (17) A label information holding unit (12), a graphic display processing unit (16), and a label information analysis unit (14). The program execution unit (24) executes a processing program corresponding to the determination result when it is determined by the label information analysis unit (25) that there is a label value within the range, and the figure display processing unit (16) When it is determined by the label information analysis unit (14) that there is a label value in the range, a message corresponding to the case where the label value is within the range is acquired from the label information and displayed on the display unit (17).
