Control apparatus, control method and non-transitory storage medium

Provided is a system capable of appropriately evaluating even an execution state of a program having a relatively low priority in execution of a plurality of programs having different priorities in a control apparatus. The control apparatus includes a first program which is repeatedly executed by the processor and has a highest execution priority, a second program and a third program, and a scheduler program which manages programs executed by the processor. The scheduler program includes a command for causing the processor to execute the second and third programs such that execution of the first program is not obstructed, and a command for determining an execution state of the second program in each predetermined monitoring cycle on the basis of a start notification and an end notification from the second program.
