ABSTRACT:
Foreground program execution means executes a program, and outputs movement commands to a control object. Meanwhile, background program execution means checks abnormalities by executing the program, without outputting the movement commands, obtained by executing the program, to the control object. If a program abnormality is detected by the background program execution means, the abnormality is stored in association with the block in which the abnormality is detected. When the program is executed by the foreground program execution means, the program is interrupted at the end of a preceding block for which a program abnormality was stored.
